Slow Internet....not same as other posts i think

Hi-

First post so please bare with me. I am having a problem with a very slow internet connection and I can't figure it out. I browsed many of the threads here and other forums before deciding to post as I wanted to see if anyone else had the same problem but it appears that I am having the opposite problem as everyone else.

My XP, Vista and Win 7 laptops all run very fast on my home wireless network (G...i have to use G because my XP laptop card is only b/g compatible...connected via comcast cable modem and netgear wgr614 router)

Now, when I am at work, we are not allowed to use wireless. We use Comcast as well and there is a linksys router (version unknown) somewhere in the building, with lines routed everywhere. In two different offices, connected to 2 different ports of the router, my Vista laptop works very well with no problems loading ANY website and my download speed is very fast.

When I plug in the Win 7 laptop, I can't load most websites and what took 15 min to download on Vista, now counts up to 3days. When I go to speedtest.net, I get a download speed of 23.47mb/s and upload of 4.38mb/s. If those speeds are accurate, then it has to be a settings issue, right?

I am not sure what info you need but here is some on the Win 7 machine

win7 ultimate 64bit
dell studio 17
intel i7 720 w/ 8gb ram
dell dw1501 wireless-n wlan half mini card
realtek pcie gbe family controller
running google chrome browser

is there some oddball setting in win 7 that I am missing or that I should check for. when my wireless at home works well and my wired connection works under an older OS...it leads me to believe that it must be a setting in Win 7 for wired connections. The laptop is brand new (received it last week) so I hope it isn't the actual network card.

thanks in advance

Could easily be because your computer uses IPv6 and the router (especially if older) uses IPv4. Type cmd in search>ipconfig /all and upload a screenshot of the output.

There is a good chance this problem is caused by out of date firmware on your office router. Updating the firmware on the older router could easily fix this type of problem.

I believe that this has more to do with the DW1501 Wireless-N WLAN Half-Mini Card
than anything else. I say this because I am having the same problems with speeds not going past 65 Mbps on the Win7Pro machine using this card. All of the other Win7Pro machines in my home with different wireless N cards are reaching around 230 Mbps while contacting the same router. I would be interested in hearing more about this.
Router is a Netgear WNDR3300.
Interesting note: When looking at the DW WLAN utility, you can see that the link is set for 270 mbps but can only achieve 65. See captures:

Your router is fine for this and most every router these days can easily handle the IPv6 protocol.

The only reason I mentioned that it could be a router problem is because usually with a newer board the problem isnt usually caused by the hardware or the driver.

If the problem is this mini card then wouldn't that be a problem with the board itself? Maybe a different driver would help in that case.

You could always try a different wireless adaptor to see if that is the problem or not.

Yea, it looks like the adapter itself as that was the first thing that I did (swap in a different wifi card). I guess that I am still perplexed as to why in the DW WLAN utility that it shows it as setup for 270 but only gives me 65. I wonder if a patch would fix this or I have some setting out of place? What do you think?
Thanks for your insight.

What kind of cable do you gave going from your modem to your router? Cat-5 or Cat-6?
Thats make the difference.

CAT6. Great question.
But that wouldn't explain why other wireless N computers on the network reach wireless N speeds and this computer doesn't. Right? Maybe I am missing something. Would love to hear your thoughts. Thanks!
