WNDR 6300v2 looses WiFi speed over time, and cannot select 5Ghz channels
Hi!
I have an older router - WNDR 6300v2 (charter version).
My network speed is 200Mbps and I know the max speed is provided by the internet company (Testing wired connection from router to my computer results in ~205/200Mbps at any time).
However, WiFi from the Router to any device results to 140/140 normally and cannot go higher. It was like this for some years.
I decided it was due to the limits of my router, however, decided to do some tests. My router could not upgrade to a newer FW as it was Charter version.
What surprised me even more was that all WiFi devices started to hit max speed as well on both FW - tablet / laptop / phone - all could get ~200 up/down. They are all either AC or AX devices.
I updated to the latest Netgear FW as I mentioned and was happy that I got max out of the device. However, my 200Mbps speed lasted until the evening - and then all WiFi devices started to do exactly the same as before - 140/140 max on any wireless device... 😞
What could be the possible cause? Restart of the router does not help.
P.S. Another issue (but that does not bother me so much) is that I cannot change channel on 5Ghz. On DD-WRT I noticed I could select width and Ch . On the Netgear FW I can only select Ch for 2.4 and there is no option at all for 5Ghz....?
However, judging by the manual - it does not mention any such options for 5Ghz for some reason.
I looked at settings and it seems that pre-selected Ch = 149 + 153(P) + 157 + 161 (Please see attached files / screenshots).
Well, maybe it is time for my old good router to be retired finally.

I tested this morning again, and the wired connection is the same max 200/200 as it should be.
My phone (AC 2x2) could not go higher than 100Mbps on wireless until I restarted the router / phone (Now 140 is the limit again), other devices also hit max 140. Ping is normally 3-5 ms, jitter - 0.2 - 1ms across all devices.
