Hey all.
This seems to be a common problem and a design flaw with this particular router so I doubt it's fixable, but it's worth trying.
Basically, 2.4GHz band works fine. Low ping, no packet loss, low jitter, good signal, pretty much perfect.
5GHz band does not work. Period. Has not worked since purchase. Not a computer problem because I've tried lots of different adapters and computers.
Usually, connecting to it gives a "the settings on this computer do not match those required for the network" error (they 100% do, trust me). During this time, signal is a full 5 bars. After 5-6 attempts it will finally connect, work at an absolute snail's pace (2mbit down compared to the usual 45mbits) then stop working. Signal drops between 1 and 0 and it will not reconnect until the router is restarted.
Any ideas? Tried various settings, including A only and N, 20mhz and 40mhz width, different signal channels. Tried 30-30-30. Same problem.
It's a Rev A piece of kit - firmware update tells me there is no update available but there appears to be one http://tsd.dlink.com.tw/downloads2008detailgo.asp
Reckon this might fix the issue?
Cheers
