Latency Issues

[mrrod]

Having problems with a wireless connected pc running windows 7 64 bit. Router is D-link DIR 615 and the nic is a DWA 130 rev c USB wireless N. I’ve had to configure the router to broadcast in G only due to the fact the nic keeps dropping connection in N even though the router is about 20 feet away with a corner of a wall just about in line of site, there’s no interference i.e. phones/microwave etc.

So my problem is the latency on the windows 7 pc. I ran a test from www.pingtest.net and got the results:

Packet loss = 12%

Ping 1541ms

Jitter 247ms

Then tested on shaw.ca site (my isp) and got the results:

6.6Mbps download speed

70kbps upload speed

I then ran the same test on my laptop running Vista (also with wireless G) the laptop is 2 feet away from the router, test results i got were:

Wired to modem

Packet loss 0%

Latency (ping) 18ms

Jitter 4ms

D/L 13.45Mb/s

U/L .97Mb/s

Wired to router

Packet loss 0%

Latency (ping) 28ms

Jitter 13ms

D/L 10.21 Mb/s

U/L .89Mp/s

Wireless

Packet loss 0%

Latency (ping) 283ms

Jitter 90ms

D/L 7.69Mb/s

U/L .34Mp/s

So, would problems with my wireless connection on the windows 7 be the setup of the USB nic and router? If so does anyone know how to resolve this issue? Or would it be the compatibility with the USB nic and windows 7? Or indeed the o/s itself? If it’s the nic, does anyone know of a good compatible nic for pcie
