Hey guys,
A friend recently upgraded his Linksys WRT54GX2 router to a Linksys WRT120N. He noticed that his Shaw internet was acting sluggish after the upgrade, so he ran a speed test. His resultant download speed with the WRT120N was 0.4Mb/s

.
He plugged the WRT54GX2 back in, ran the speed test, and the result was around 8Mb/s.
That's when he called me for help. I checked over all his settings on the WRT120N but nothing jumped out at me that should be affecting his download speed so dramatically.
Just out of curiosity, I plugged in a DLink EBR-2310 non-wireless router that I had kicking around and ran the speed test. Again, his download speed was a shitty 0.5Mb/s.
Any ideas why his speeds would be so slow with the WRT120N and the EBR-2310, but fast with the old WRT54GX2? I have never seen this problem before on home quality routers, so I am at a bit of a loss.
