2.4G Wifi on Eir F2000 Modem

06.07.2018 13:56 #1
I recently had Eir fibre broadband installed and am very happy with it. My connection speed has moved from 8Mbps at best to 150 Mbps at best.

However I seem to have an issue with the 2.4G WiFi network. I have seen similar issues reported, but none match the symptoms I am seeing:

The download speeds on this Wifi network seem to degrade over time. It gets down to as low as about 1mbps. I can resolve it by restarting 2.4G (disable & re-enable on the router), but then it degrades again over the next 24 hours. This happens even for devices held right beside the router, so it is not a signal issue.

5G and wired work fine, but I do still need 2.4G as it has better reach (in this old house) and I still have some devices that do not support 5G

Any suggestions?

Try twiddle with settings disable ipv6
Disable network broadcasting
Check where you put the router is it next to a ton of wires in a cabinet
Is there aluminium sheeting around near it.
Get a WiFi band scanner app and check if there are any other WiFi signals broadcasting on that channel louder than yours? If so change to another.

Thanks - I'll try those. But would any of them cause 2.4G Wifi to degrade over 24 hours (vs being crap from the start) and have no impact on 5G?

I once had an issue with an neighbours old microwave from the 80s interfering with my WiFi before used to drop out almost completely for 15 minutes around the same every evening.
Only noticed it when I was then next door and my mate was online when it dropped on him too about the same time and he commented that someone was using the microwave again and would have to wait.
However I have not come across anything that gets weaker and weaker throuout the course of the say. 
Is it overheating?
A replacement modem or a better modem may resolve

was there any resolution to this?  Mine does the same thing all the time.  Have to restart daily.

Hey Patton, can I ask what your tech level is that you're comfortable with?

I bought a TP-link archer C50 AC1200 (v4) router for 50 euros, and it solved all my Wi-Fi problems. Basically, the router handles WiFi connection to your devices, and then passes the traffic through an ethernet cable to the Eir modem/router.

I installed OpenWRT on it to increase stability and performance, but I'd describe the required technical level how to do that as moderate difficulty.
