Windows 7: Wireless/Wired problems with internal network

Wireless/Wired problems with internal network

I have the following setup:

Actiontec Q1000 modem from Qwest setup as wireless access point
D-Link DIR-615 router setup as a wireless access point without the DHCP server and plugged in directly to the Q1000

I have a Toshiba Satellite A205-S5864 with an Intel 3945ABG wifi card with the latest drivers from Intel. When I'm connected wirelessly to the Q1000 I can't see any of the other wired devices but can see other wireless devices. If I connect wired to the Q1000 I can see all devices. However, if I connect to the DIR-615 wirelessly, I can see everything fine as well. I'm even getting the same DHCP lease from both wireless access points.

I have network discovery on, password protected file sharing off, firewall off and unneeded network services turned off (IPv6, etc).

When I can't see the wired devices this includes ping, http, ssh and samba.

Windows 7 Ult, Windows 8.1 Pro,

Dual router set ups aren't recommended unless you like inconsistant networks that are plagued with problems.

The way you have this set up now will only cause you problems. Go with a standard modem, not a combo unit, then use your same router and turn back on all networking services including IPv6.

The Argument against Disabling IPv6
It is unfortunate that some organizations disable IPv6 on their computers running Windows Vista or Windows Server 2008, where it is installed and enabled by default. Many disable IPv6-based on the assumption that they are not running any applications or services that use it. Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. This is not true.
From Microsoft's perspective, IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6. If IPv6 is disabled on Windows Vista, Windows Server 2008, or later versions, some components will not function. Moreover, applications that you might not think are using IPv6—such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail—could be.
Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. By leaving IPv6 enabled, you do not disable IPv6-only applications and services (for example, HomeGroup in Windows 7 and DirectAccess in Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can take advantage of IPv6-enhanced connectivity.

A few things.

The second router is setup as per manufacturers instructions on how to set it up as a repeater which is why it's there. It's plugged directly into Qwest's router/modem but through the built in Ethernet cables in the home.

I tried it with both IPv6 on and off so that's not really the issue. I usually don't turn it off but I know some people always blame network problems on it so I tried it just to same myself a step.

Also, none of the wired devices are plugged into anything but the Qwest modem. Two other PCs (1 is Win7 and 1 is XP) have no problem accessing the wired network devices from their wireless connections. And the same laptop that's having the problem has no problems in Ubuntu.

Windows 7 Ult, Windows 8.1 Pro,

We have this tutoral here for dual router sets up that might help. It might just be a problem with the laptop only.

If you keep having problems then post the ipconfig /all from the laptop with the problem and we can go from there. I have an idea of what this problem might be but I'd have to see the ipconfig from the laptop to know for sure.
