Hello,
I'm having some wlan speed problems with my RT-N66U and Merlin fw 374.40.
I used to connect my laptop through its stock 1x1 wifi card and I used to get the expected 150Mbps on the 2.4GHz band (with channel bonding). This meant actual 7MB/s, which is to be expected (AFAIK).
I have now switched to a 3x3 Intel 6300 nic to improve lan transfer speed. But to my surprise this hasn't happened. The link speed is low: usually about 200Mbps but sometimes drops to about 100Mbps. Moreover, the actual transfer speed hasn't improved at all: about 7MB/s.
This was tested doing a lan transfer to both the router's hdd and a gigabit lan desktop. Note that the transfer speed between the desktop and the router's hdd is about 19MB/s (the router's cpu is the cap here).
This is not a problem of wireless coverage, because signal power actually improved with the Intel 6300 (from 50 to 40 dBm). Anyway, I've also tried staying very close to the router, to no avail.
I've tried to force the wifi to 20MHz (btw the 2.4GHz band isn't crowded at all) and nothing changed.
I've tried managing the nic's options in device manager but nothing changed.
This was tested on both Ubuntu and windows XP.
Could anyone please provide some advice to troubleshoot this? I'm out of ideas at the moment...
Thanks
