The Graveyard - Products No Longer Supported => Routers / COVR => DIR-655 => Topic started by: JN99 on July 04, 2013, 03:14:22 PM

Ok, I have read many posts here and elsewhere on this issue and must admit a limited understanding, which might be the problem really... I have a DIR-655 revA on current firmware. I have 3 different computers connecting, all with wireless-n cards but the max any will connect at is 65Mbps. Signal strength is fine, there just seems to be this cap for some reason and I cannot figure out how to get past it. There is one wireless G device (a printer) so I cannot set the router to n mode only and perhaps this is the issue? Otherwise the router is set to mixed mode g-n, auto bandwidth (appears throttled to 20MHz though - again is this the issue?)
Anyway, overall happy with this router but trying to increase performance now and not sure this is a router issue, a bandwidth issue (i.e. running at 20MHz) or what. Seems at a minimum one of these computers should connect at 130, 150, or even as much as 300Mbps but no dice.

The best way to get the maximum speed is to have matched wireless NIC cards to the router, in other words D-Link wireless NICs with a D-Link router. Different companies use different methods in order to get max throughput. The presence of the G item is most likely causing the drop down you are seeing. You could switch to N Only for testing purposes and then back to G + N was you are done checking it out as N only.

Also you need to set the band width to Auto 20/40Mhz. If one of the devices doesn't support 40Mhz, then this also could effect how the connection speed is behaving.
