Win7 won't work with Cox Comm

[snbaker]

I've installed several Win7 PCs on a small office network, along with XP PCs. We're on Cox for our ISP. XP machines work fine but Win7 web access is poor. Only 50% of websites open at all. Other 50% are spotty even when they do open. No limited graphics etc. I've tried other browsers and same problem. Used an air card to get around the network and I have no problems. It's got to be something with Cox but they of course tell me no way. Has anyone else had networking problems with Win7 with Cox or another ISP? Thanks!

is this problem machine the only windows 7 box in the "small office network". Are you in a domain environment? Are you using dynamic addressing? Are you using a firewall/router/switch for traffic routing?


Have you disabled Ipv6?

 

[snbaker]

We're not in a domain environment. 3 Win7 machines and 4 XP. We're using static IPs behind a PIX 506 firewall, and Cox as ISP. Would PIX cause a problem with Win7 and not XP?

 

[brady]

Did you set the static Ip addresses under the Ipv4 or ipv6 properties?

what does the ipconfig /all say on your windows 7 machines?

 

[snbaker]

All using v4.

Here is ipconfig /all

[brady]

can you now put your ipconfig /all for a working xp machine?

public dns looks to be an issue at this point but I'm not sure why your xp machine(s) would handle this setting better than your 7 box.

 

[snbaker]

Here's the ipconfig /all for an xp machine

and finally:

Used an air card to get around the network and I have no problems

please connect with this aircard, and post your ipconfig /all while connected and able to view sites just fine.

 

[snbaker]

Here's with the aircard (actually a mobile phone tether)....

[brady]

ok, change your DNS server(s) addresses on your windows 7 computers to:
8.8.8.8 and 8.8.4.4

 

[CommonTater]

We're not in a domain environment. 3 Win7 machines and 4 XP. We're using static IPs behind a PIX 506 firewall, and Cox as ISP. Would PIX cause a problem with Win7 and not XP?

Does your router/firewall have a DNS relay built in?

If it does then your DNS should be set to the firewall not your ISP. You might have problems with both WAN and LAN functions aiming this beyond the firewall.

Since the firewall gateway is 192.168.20.1, that's probably where you should set your DNS as well.

I would also suggest that you disable (uncheck) IPV6 support in your network adaptors and test...

 

[snbaker]

Hi,
Tried to set DNS to 192.168.20.1 and 8.8.8.8 and no go on either one. My current DNS settings were what my IT guy who handles my DNS suggested I set them at. Never had any trouble with the settings before upgrading to Win7. Thanks for the suggestions....

 

[brady]

both are public dns settings, while bypassing your network on the 7 boxes you were connected to those google dns servers I had listed above. I wanted to see if it was your public dns that was limiting your site connectivity.

Can you run a tracert to a non working site on one of the windows 7 boxes?

 

[chev65]

I'd have to take down the third party firewall and see if that works, they cause nothing but problems with Windows 7. This is a firewall problem in case you weren't aware. The fact that you can only get to certain sites also points to a firewall problem.

 

[snbaker]

tracert to google times out. Nothing returned. Regarding the firewall, I thought it would be the issue as well, but I didn't think the firewall would allow data from an XP computer and not allow data from a Win7 computer. Wouldn't the "traffic" look the same to the firewall whether it is traveling to/from an XP machine or a Win7 mahcine? Thanks!

 

[brady]

What are the windows 7 firewall profiles set to? What anti virus?

 

[snbaker]

I've turned off windows firewall and removed all virus software. my Pix firewall should keep out most viruses anyway, right? I've cranked security settings down to a minimum as well.
