Cannot connect through wireless after Windows 8 upgrade

Hi,

I just upgraded to Windows 8 on my work computer. I work from my home office quite a lot and connect wirelessly at home. I have a Netgear RangeMax WNDR3700 router at home that is connected to my broadband modem. Here's the observations I've made:

1. I cannot connect the wireless network at home from my work laptop - it connects but says I have "Limited Access".
2. I can connect to the wireless network at home through other devices (laptop, phone, Kindle, TV). I am able to access the internet without any problems.
3. I can use an Ethernet cable to connect my work laptop directly to the router and it works great.
4. I can connect to the wireless network at work through my work laptop and that works too.

The only thing that doesn't seem to work is when I connect my work laptop wirelessly to the router at home. I can't figure out what's going wrong.

When I try the diagnosis process in Windows, I am told to shut down and restart the modem/router to see if that fixes the problem. It does not.

Anybody have any ideas on what else I could try. Anyone else experiencing this?

If you can see the connection from the system tray icon, clik and then right click for the properties. Make sure that the security/encryption is the same for laptop and router... also, add the default gateway (router ip address) in the ipv4 properties advanced button.

Tried doing that but it didn't work. I had the IPv4 setting to auto-detect IP. Changed that and put in the specific IP address for the gateway but that didn't solve the problem. Either way (with or without IP auto-detection), I am unable to ping the default gateway when connected through wireless. It works just fine when I am on the wired connection. My router settings are accessible on 192.168.1.1. I can't even get to this page when on wireless although it says I'm connected. I have verified that the SSID and passphrase settings are correct. When I auto-detect IP on the wireless adapter the default gateway is set to that address - 192.168.1.1. So no wonder it doesn't work. Now I need to figure out why this doesn't work. It used to work fine on Windows 7.

With upgrades sometimes winsock or the TCP/IP stack gets corrupted. To reset them both type the following two commands into an elevated command prompt one at a time hitting enter after each one then reboot the system. :)

netsh winsock reset catalog (reset winsock entries)

netsh int ip reset reset.log hit (reset TCP/IP stack)

Thanks for responding, chev65. I tried that too. Didn't work. I still can't ping the gateway. Actually, it got a little weirder now. Most times, I see the ping request timing out on all packets sent. But sometimes, I see 1 packet succeed out of 4. Sometimes 2. It is totally random. Also, when the random packet does succeed, it takes over a 1000 ms for the round trip. When on the wired connection, the response is always < 1ms. I don't know how to interpret any of this. Seems to indicate that the connection is live but it is just taking too long for the laptop to communicate with the router. I have a very strong signal, am sitting right next to the router and no other device seems to have a problem.

If you happened to have a third party security/anti virus program installed, uninstall it and see whether it helps.

Thanks, brummyfan. Whatever security or antivirus settings I have on my computer right now are the same ones I had with Windows 7. I didn't have any problems with Windows 7. It probably still helps to check if it makes a difference - unfortunately, I cannot disable the settings on my computer by myself because it is a work laptop and security settings are managed by the IT Admins. I will have to wait for them to help me with this.

If the computer has security software like Avast it breaks all kinds of things I had similar problems.

What I have on my laptop is Microsoft System Center Endpoint Protection. It was the same solution I had on Windows 7 and it was constantly turned on. I didn't have any problems then. I don't know if the combination of SCEP and Windows 8 networking is special in any way as to cause patchy wireless communication to the router. I do intend to find out but I have not been given sufficient privileges on the machine to turn off the protection. I am awaiting Security Administrator assistance with this.

It may be because the work laptop is on a Domain so changing the network location to private may help.

Didn't have any problems signing on with a computer on a domain ever before. I did find something very interesting this morning though. I turned on the Hyper-V feature and configured an "External" Virtual Switch to use the host OS network card. Suddenly, communication with the router ceased (or started timing out to be more accurate) when on the wired connection. And miraculously, the wireless now worked with no hitches. This was odd; so to experiment more, I went back to Hyper-V manager and reconfigured the virtual switch to use the wireless network adapter instead of the NIC. Sure enough, the problem switched back over to the wireless adapter (communication being suppressed when on wireless connection). Next experiment, I changed the virtual switch to an "Internal" type. Now, both the wired and wireless connections work just fine. The only inference I can make (at least since I turned on Hyper-V) is that whatever underlying adapter the virtual NIC happened to leverage was hampered (can't think why or probably don't understand Hyper-V deeply enough). I still have no idea why the problem existed before I turned on Hyper-V. Just very confused at this point.

If I knew there was a virtual switch involved I would have instantly placed the blame firmly on that. Been there done that. :)
