GivEnergy Router Configuration — WiFi Setup for Your Inverter

GivEnergy inverters only connect to 2.4GHz WiFi. Most modern routers default to a combined band that includes 5GHz — and many will steer the dongle onto the wrong band without telling you. This guide covers exactly what your router settings need to look like, and how to fix the most common ISP router configurations.
  • 2.4GHz, WPA2 & band steering explained
  • BT, Sky, Virgin, EE & mesh networks covered
  • Ports 7654/7655 for cloud connectivity
WiFi configured but still offline?

If you've separated the 2.4GHz band and the dongle still won't connect — or connects but the portal stays dark — we diagnose GivEnergy connectivity issues remotely. We access the portal data to identify whether the fault is local WiFi, the dongle itself, or GivEnergy's cloud.

I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Hugh Speirs · Apr 2026 Trustpilot

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning.

Requirements
Requirements

What your router needs to support GivEnergy

GivEnergy's WiFi requirements are straightforward but strict. Meeting all conditions is necessary — the dongle will fail silently if any one is missing.

Requirement What it means Why it matters
2.4GHz band A dedicated 2.4GHz SSID the dongle can connect to Dongle hardware does not support 5GHz — connection will fail
WPA2 security (AES) Wireless authentication set to WPA2-Personal, not WPA3 WPA3-only routers block the dongle from authenticating
DHCP enabled Router assigns IP addresses automatically Static-only networks require manual configuration not supported by setup wizard
Alphanumeric password WiFi password uses letters and numbers only Special characters (@, #, $, %) cause dongle setup failures
Signal at inverter RSSI 60% minimum; 70%+ recommended (as shown in GivEnergy app portal) Below 60% causes disconnections — GivEnergy recommends ≥70% for reliable operation
Port 7654 outbound TCP port 7654 must be open outbound on the router or firewall Some ISP-provided routers block non-standard outbound ports — dongle cannot communicate with GivEnergy cloud
Band steering
The main issue

Band steering — why it breaks GivEnergy connectivity

Band steering is a router feature that broadcasts a single WiFi name for both 2.4GHz and 5GHz, then automatically assigns devices to the faster band. For most devices this improves performance — for GivEnergy, it breaks connectivity entirely.

What happens

The GivEnergy dongle connects to your WiFi network name (SSID). The router's band-steering logic detects a new device and assigns it to the 5GHz band because it appears signal-capable. The dongle's chipset cannot use 5GHz and the connection fails — usually with no meaningful error message.

Why it's hard to diagnose

The dongle setup wizard may appear to succeed — the WiFi credentials are entered correctly and the wizard completes without error. But the dongle then fails to maintain a connection, or connects briefly and then drops. The portal shows offline. Many users assume the dongle is faulty when the router is the cause.

The fix

Log into your router admin panel and either: (1) disable band steering and give the 2.4GHz and 5GHz networks different names, or (2) if your router doesn't allow separation, create a guest network limited to 2.4GHz only and connect the dongle to that. See the step-by-step guide below.

Not just band steering: Even after separating the bands, check that your 2.4GHz network is set to WPA2 specifically. Some routers default the 2.4GHz band to WPA/WPA2 mixed mode with TKIP, which GivEnergy dongles also reject. Set the 2.4GHz security to WPA2-Personal with AES encryption only.

Step by step
Configuration

Router configuration — step by step

1
Access your router admin panel

On a device connected to your home WiFi, open a browser and enter your router's gateway IP. The most common addresses are 192.168.0.1, 192.168.1.1, or 192.168.1.254. The correct address is usually printed on the router label. Log in with the admin credentials — these are separate from your WiFi password and are also on the router label unless you've changed them.

2
Find the wireless / WiFi settings

Navigate to the wireless or WiFi section of the admin panel. You are looking for settings that control the 2.4GHz and 5GHz networks separately. If you see only one network with no band selector, your router uses combined band steering — look for a "Smart WiFi", "Band Steering", "Smart Connect", or "Band Management" option to disable it first.

3
Separate the 2.4GHz and 5GHz networks

Disable band steering or smart connect. Then set a unique SSID for the 2.4GHz network (e.g. YourNetwork_2G) and a different SSID for the 5GHz network (e.g. YourNetwork_5G). This ensures the GivEnergy dongle can specifically connect to the 2.4GHz band. Note the 2.4GHz SSID and current password — you'll need these for the dongle setup.

4
Set security to WPA2 (AES)

Under the 2.4GHz network's security settings, select WPA2-Personal as the authentication mode. Set encryption to AES (also called CCMP). Avoid WPA/WPA2 mixed mode with TKIP — while many devices accept this, GivEnergy dongles do not handle TKIP reliably. If your router only shows "WPA2+WPA3" mixed mode, select WPA2 only for the 2.4GHz band.

5
Check your 2.4GHz password

If your current WiFi password contains special characters (@, #, $, %, &, !, quotes, or slashes), change it temporarily to a purely alphanumeric password of 8–20 characters. Complete the dongle setup with this simpler password. Once confirmed working, you can change the password back — but you will need to reconnect all wireless devices including the dongle.

6
Save settings and reconnect the dongle

Save your router settings and allow 60 seconds for the router to apply them. Now run the GivEnergy dongle setup using the 2.4GHz SSID and password you've just configured. Within 5–10 minutes the dongle should appear as connected in the portal. If the portal is still offline after 15 minutes, see the portal offline diagnostic guide.

ISP guide
ISP-specific

Band separation by ISP router

BT Smart Hub 1 / Smart Hub 2

Band steering on by default

Go to 192.168.1.254 → My Network → Advanced Settings → Wireless. Enable "Use separate band names" and assign different SSIDs to 2.4GHz and 5GHz. The admin password is printed on the hub's label — it is NOT the same as your WiFi password.

Note: BT's "Whole Home" mesh discs do not support band separation in the standard app. Use the Smart Hub 2 admin panel method above — it applies to all discs on the network.

Sky Q Hub / Sky SR203

Band steering enabled

Go to 192.168.0.1 → Settings → Wireless → Advanced. Set "Wireless Band Steering" to Disabled. Two separate SSIDs will then appear — assign different names to each. Sky's admin password is on the bottom of the hub.

Sky Booster pods and Broadband Boosters share the same SSID — once you separate bands on the main hub, boosters follow.

Virgin Media Hub 3 / Hub 4 / Hub 5

Band splitting available

Go to 192.168.0.1 → Advanced Settings → Wireless → Smart WiFi. Toggle Smart WiFi off. Two separate network entries appear — configure the 2.4GHz one with a distinct name and WPA2-AES security. Hub 5 users can also manage this via the My Virgin Media app under router settings.

EE Smart Hub / EE Full Fibre Hub

Band steering on by default

Go to 192.168.1.1 → WiFi → Advanced WiFi Settings. Disable "Band Optimisation" or "Smart WiFi". Assign separate SSIDs to 2.4GHz and 5GHz bands. EE's newer hubs may require a call to EE support if this option is not visible — ask for "band splitting" to be enabled.

Plusnet Hub One / TalkTalk Wi-Fi Hub

Generally straightforward

These routers typically broadcast separate 2.4GHz and 5GHz networks with different SSIDs by default. Connect the GivEnergy dongle to the 2.4GHz network. Confirm it is set to WPA2-Personal (AES) in the admin panel under Wireless Settings.

Mesh networks
Common issue

GivEnergy and mesh WiFi systems

Mesh systems — Eero, Google Nest WiFi, BT Whole Home, TP-Link Deco, Amazon Eero — all use a single combined SSID. Most do not allow per-band network separation. GivEnergy dongles have the same band-steering problem with mesh as with standard routers, but the fix is different.

The mesh problem

Mesh systems are designed for seamless roaming — separating 2.4GHz and 5GHz defeats their purpose. Most mesh apps do not expose this option. Some advanced Eero models allow a separate IoT network, but it may still be dual-band. Most TP-Link Deco units allow you to disable band steering in the Deco app under More → Wi-Fi.

The reliable fix

Run a short Ethernet cable from any Ethernet port on a mesh node to a simple dual-band access point (or a basic router in access-point mode). Configure that access point with a separate 2.4GHz SSID and connect the GivEnergy dongle to it. The dongle gets reliable 2.4GHz connectivity; your other devices continue using the mesh. This is the most reliable long-term solution.

Powerline alternative: If running Ethernet to the inverter location isn't practical, a powerline adapter pair with a built-in WiFi access point (e.g. TP-Link TL-WPA4220) gives you a dedicated 2.4GHz network near the inverter through your house's existing electrical wiring. Most homes with solid-core ring mains see reliable speeds — avoid using powerline if the inverter is on a different circuit or through an RCD board.

Signal & cloud
Connectivity

Signal strength and outbound port requirements

Signal strength at the inverter

GivEnergy specifies a minimum RSSI of 60% (as shown in the GivEnergy app portal), below which connectivity issues occur. The GivEnergy dongle troubleshooting guide recommends ≥70% for reliable operation — treat 60–70% as marginal and 70%+ as the target. Use a free app such as WiFi Analyser (Android) or Network Analyser (iOS) to check signal at the inverter location. An Ethernet cable, powerline adapter, or WiFi extender in AP mode is the correct fix — not a stronger password or router reboot. The dBm table below provides a technical reference for engineers.

RSSIResult
−50 to −65 dBmExcellent — above GivEnergy's ≥70% recommended threshold
−65 to −70 dBmMarginal — between 60% minimum and 70% recommended
−70 to −75 dBmBelow 60% minimum — expect dropouts; improve before commissioning
Worse than −75 dBmPoor — improve signal before proceeding

Outbound port requirements

Once on the local WiFi, the GivEnergy dongle communicates outbound to GivEnergy's cloud servers. Most UK home broadband does not block these ports — but custom firewall rules, parental controls, or some business broadband packages may. If the dongle appears on your local network but the portal is dark, check whether outbound TCP traffic on these ports is allowed.

When to call STS — beyond router configuration

Most GivEnergy WiFi problems are solved by the router configuration steps above. If you have worked through the full guide — separated 2.4GHz, set WPA2, checked the password, confirmed DHCP — and the dongle still won't connect or keeps dropping, the problem is likely beyond router configuration.

Signs the dongle itself has failed

Router correctly configured but dongle shows constant error state or no LED activity
Dongle connects briefly then drops repeatedly even with strong signal at the inverter
Dongle does not appear in the router's connected devices list at all
WiFi configuration interface (AP mode) is no longer accessible
Updating the dongle firmware did not resolve the issue

Signs the issue is cloud-side or firmware

Dongle connects to WiFi (visible in router) but portal stays offline
Portal shows device as online but data stopped updating at a specific date
Issue started immediately after a firmware update
Outbound ports 7654/7655 are confirmed open but portal is still unreachable
Remote diagnostic — we review your portal connectivity

If you have exhausted the router configuration steps and the dongle still won't connect, or the dongle is connected but the portal won't come online, we diagnose your system's connectivity path remotely. Most GivEnergy connectivity faults are resolved without a site visit — from £75.

FAQ

GivEnergy router configuration questions

GivEnergy inverters and All-in-One units use WiFi chipsets that only support 2.4GHz. This is common in IoT and embedded devices — 2.4GHz has better range and wall penetration than 5GHz, which matters for inverters in garages, utility rooms, or on external walls. GivEnergy dongles, including the AECC multi-connect and the HF21, cannot connect to 5GHz networks under any circumstances.
A single network name means band steering is active. Log into your router admin panel (the address is on the router label) and look for settings called "Band Steering", "Smart Connect", "Smart WiFi", or "Band Optimisation". Disable this feature and the router will show separate 2.4GHz and 5GHz networks which you can give different names. The ISP-specific instructions on this page cover BT, Sky, Virgin, EE, and Plusnet step by step.
Most mesh systems use a combined SSID and do not support band separation. The most reliable fix is to add a separate 2.4GHz-only access point (connected via Ethernet or powerline from a mesh node) near the inverter, and connect the dongle to that dedicated network. Some mesh apps (TP-Link Deco) allow band steering to be disabled — check your app settings under More → Wi-Fi or Advanced WiFi.
WiFi connectivity and cloud portal connectivity are separate. Once the dongle is on your local network, it communicates outbound to GivEnergy's cloud servers on TCP ports 7654 and 7655. If your router or ISP blocks these outbound ports (rare on standard home broadband, but possible with parental controls or custom firewall rules), the portal stays dark. Check whether outbound TCP traffic on these ports is permitted. Also check the portal offline guide for cloud-side outage checks.
Persistent disconnections after correct band setup are almost always a signal strength issue. Check the RSSI at the inverter location — GivEnergy specifies a minimum of 60% (as shown in the app portal) with 70%+ recommended for reliable operation. Anything below 60% is too weak; 60–70% is marginal. A WiFi extender in AP mode (not repeater mode) placed closer to the inverter, or a powerline adapter with WiFi, is the standard fix. Also check that DHCP lease time is set to at least 24 hours, that any router power-saving features that disconnect idle devices are disabled, and that outbound TCP port 7654 is not blocked by a firewall rule.
