Hi

Just purchased an Edimax MIMO router [BR6216mg] and MIMO Cardbus adapter [EW7608pg] both use ralink chipset

 

Everything works well except the following issue

 1. When I look at the statistics in the RAlink wireless utility it shows huge numbers of frames received with CRC errors 
 

I suspect this is why I am only getting 8Mbps [when coping a large file from the laptop to a PC ethernet connected to the router. Furthermore this issue occurs when the router and laptop are next to each other despite good link quality, signal strenghs 1 & 2 and low noise.

 

2. I upgraded my Windows 2000 SP4 laptop to V1110 drivers but this made no difference. I haven't upgraded the router yet.

 

3. I have tried every channel and also turned off all 2.4Ghz phones, Microwaves and even Cellphones to isolate potential interference

What could the issue be ?

 

Kind Regards

Just an update so peps can benefot from my learning curve

1. Receive CRC frame errors are appear to be standard for 802.11b/g setups

2.  Performance issue was that I was copying files from the wireless client to a 300Mhz Win98 ethernet connecrted PC, when I did the same to a 1Ghz XP machine the performance when up to 25Mbit
