Archer VR2800 5Ghz stops working
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Every few days or so, the 5Ghz network stops working on my Archer VR2800 for all my 5GHz devices. Devices appear to be connected, but there is no data throughput at all. The only way to get it back working is to reboot the router.
Devices on the 2.4GHz network are unaffected. If I connect to the web interface via a device on the 2.4Ghz, I can see no errors shown in the log (log level is set to All and Debug) and the modem thinks the 5GHz network is working fine.
After a reboot, everything comes up fine for another few days. I highly doubt this is wi-fi interference, as upon reboot all the 5GHz network settings (channel, width etc.) are the same as when it stopped working.
This really is a poor piece of kit. No wonder TP-Link included the option to schedule a restart on it.

@TP-Link It isn't! Getting this error: "Fehlercode: 4503 - Die eingeladene Datei wurde nicht akzeptiert."

@TP-Link I have this problem too. My firmware is up to date. I cannot follow the recommendation to change the channel to 40 and width to 40MHz as I get an error code 80002 : Unknown error.
We have only had this problem for a month or so, but it seems to be getting more frequent.

Hi, I noticed that your model number is Archer VR2800V, not Archer VR2800;
And you already have the latest firmware for Archer VR2800v;

Hi, the reason why you wanted to change the channel and channel width is because of the unstable 5ghz connection, right?
Did the error code only appear when making these changes?

@TP-Link Thank you! Changing my channel and channel width resolved my 5ghz problems I have been having for ~2 months. I had started suffering drop outs, slow connections and inability to connect to other devices on the network. Everything is much smoother again now. It also prompted me to learn what these settings actually mean.

@TP-Link I tried EVERYTHING. The router rebooting every time. When there are both 2.4 and 5ghz connections enabled, and there is a peak of 2.4g (like Speedtest or streaming a video), the modem reboots. When I enable ONLY 2.4 or 5ghz everything seems to keep working but I can't use just 5ghz because my two RE500 repeaters are too far, and I can't cover my whole house if I move them)
I already changed my modem with another identical one (VR2800 v1 00000000), tried every firmware (even beta) and every Wi-Fi setting in both bandwidth, I'm pretty disappointed about that.
p.s. the solution doesn't solve the problem.

Hi, sorry for the delay.
I saw that you mentioned you had already replaced with another identical Archer VR2800 and did both of them have the same issue?
When the VR2800 rebooted himself, did you see all the lights turn off then come back on?
After that, if you go to the system tools>system logs, would all the logs be cleared out?
At the same time, may I know how many devices are connected to 2.4ghd and 5ghz and what are their model numbers?
Thank you very much

I've had 3 of the same Router, I've told TP Link, they just go through a bunch of tips but they do not fix, waste of time really.
when the 5Ghz disappears you won't get it back the only way is to reboot or turn off the router. TP-Link won't help they just offer to replace the router but replacing the router won't even fix the issue because it happens again! This is definitely a bug in the software and it really is annoying! After the price we pay for this product but yet it gives rubbish results.
Tp-Link probably don't know how to fix it hence why they keep wanting to replace rather than try fixing the firmware.

Hi, Thank you very much for getting back to me.
I am sure that we definitely want to fix this issue.
Based on the previous troubleshooting records, several of them are caused by the broken 5Ghz wireless module while the rest have no replies.
Your case is very rare and I see you have opened a support ticket with us.
Our senior engineers tended to collect your device back and replace it with Archer VR2100 so that they could run further tests to locate what might cause the broken 5ghz module.
But it seemed not going on well.
Do you still keep the Archer VR2800 or it has been returned back to Amazon?
Thank you again for your time and patience.
