Yes ive done that, which didnt make a difference. So i did a factory reset this morning. Its been at full speed for about 90 mins so far. Strange one. I think i need to lesrn more :-)

@pcuttle stopped working I can't understand. I've set the channel and channel width to 80 but doesn't seem to work. The thing I can't understand is why does it work at full strength for like 5 mins....

@pcuttle I've managed to force the 5g 2 into 80mhz as opposed to auto. That seems to help. I'm not sure why it wouldn't help earlier.

Where can i see the latest version?

Hmm my app tells me my firmware is up to date

My 5g 2 is running slow and I cannot seem to fix it. Its a tri-band router and all three have auto settings for Mhz and channel. Interestingly when I power the router on the 5g 2 works at full speed...
