I am on BT gigabit internet so get around 900mbps download. The router has been working great for a couple of months but all of a sudden the 2.4ghz channel has dropped from speeds of 400-500Mbps down to 50-100mbps.
Luckily the 5ghz channels remain fine and i can get close to 700mbps with these.
I have just tried a factory reset (using a pin on the back of the router) and completed a firmware update but nothing has helped.
I have also checked wifi congestion using Inssider and tried different channels but nothing has worked.
All the 2.4ghz settings are on max, mode 1200Mbps, 100% power etc. Also tried 20/40 coexisitence on both settings but again no difference.
I am convinced the router must be faulty (for the 2.4ghz channel) - but thought would check here first.
Seperately - if it is faulty can anyone confirm the process to log this in for repair with Netgear?
You can try changing what channel you're broadcasting on in case there's interference.
If you live in an area without much for wifi (rare) you could disable wifi 20/40hz coexistance. I wouldn't recommend doing that if you live around others with wifi
Thanks for the reply - after doing some more reading, you could well be right.
I was sure i had tested 2.4ghz speeds when i first got the router but maybe i was only testing 5ghz speeds. Maybe real world speeds for 2.4ghz have always been this slow from when i first installed it and its just now that i am only realising how big the gap is vs 5ghz.
Reading some of the reviews you refered to - 100Mbps seems a fair reflection..
With my RAX, I usually just have my low bandwidth devices on 2.4ghz. Like my IoT devices, ereaders, etc. Or my devices that are at the peripheral that need the extra range the 2.4ghz provides.
Nice thing is that most device don't need a ton of bandwidth. You can stream 4k with 30-40mbps (if its stable) connections.
Again, you can try changing channels to see about optimizing a bit.
