Wireless Slow Download Speed/Fast Upload

Hi Everyone,

I was just wondering if you know what would cause a download speed to be at 0.5Mbps and about 6 Mgps upload if I connected using wireless to a Netgear 3500XL and if I direct connect a cable to it, the speed is about 40Mbps/20Mbps upload (normal speed).  We went through all the settings on the Netgear and disabled all unnecessary services and that didn't make any difference.  Also, when I tracerouted, the latency seem to be normal out to the ISP (Comcast).....

It is not the laptop as it is the same issue with different devices. Does anyone have any idea?

I have had this same issue happen to me when I setup Wifi in pfSense using a rosewill wifi card that had the RNX-G300 chipset.  The upload speed was normal but download speed was reduced to the minimum which was 1 Mbps.  I have been unable to determine the source of the problem but it seemed to do with the wifi chipset in the router and problem negotiating speed, so in your case the Netgear.  It may have a similar chipset.

What I did was replace the wifi with an Apple Airport Express and the download speed returned to normal.  So you might try a different wireless router to see if there is any improvement.  If that is not an option, check to see if there is a firmware update for the 3500XL which may help.

Could be interference.  Have you tried changing the wireless channel on the AP/router?
