Technicolor 582n reporting 5.5Mbps wireless not 130Mbps - Slow transfers

[#1]

Hi
My Technicolor 582n reporting 5.5Mbps wireless tonight in the web interface and file transfers from my server to laptop are unusable.

[#2]

Its definetly a router fault.  I've tried on LAN cable and broadband runs at full speed of 3.6Mbps and file transfers on my local network are as they should be.
On wireless I'm only getting 1Mbps and file transfers on the LAN are under 200Kbps.

How far away from the router are these wireless devices? Also have you looked at changing the wireless channel being used?

In the same room, but that doesn't matter as the router has been fine since I got it a few weeks back.  Only today has it started doing this.  I'm using the same channel as I have been, nothing has changed.  I use a wifi analyser to find the best channel to use.

My Dell laptop with a 1704 wireless card has done this from new (it's around a week old)  but with a TP-Link router.  I'm having to use a wireless dongle to get any decent connectivity.

May be a neighbour has changed something that has impacted your WiFi operation.  Note that wifi analysers do not detect all uses of the 2.4MHz band.
