Can't connect via wifi only thru USB and no IP address

I've been trying to figure this out for weeks with no help from Comcast or my tech support. I have several wireless devises and They all work fine. No issues getting online. Then I have a laptop, identical to one of my others and this one says "no internet access". It shows (on the diagram)that the device is connected to the home group but the home group is not connected to the internet.
Equipment is: Arris TG862G. I plugged the laptop directly into the router and got internet access that way so I tried renewing my IP address. Ipconfig /release and ipconfig /renew. The result was:

Wireless LAN adapter Wireless Network Connection: Media disconnected
Also Ethernet adapter local area connection: Media disconnected
It goes thru a bunch of other lines with the same results

Also subnet Mask 255.255.255.0
Default gateway 10.0.0.0.1

Not sure what's important.
Thanks for your time! Appreciate it!

On your network adapter (wifi card), are you trying to set your ip staticly or are you letting the wifi card learn the new address dynamically (recommended)?

You need to make sure whatever method your trying to establish your ip address, that its the same as your wifi router. I don't think your default gateway of 10.0.0.1 will work.


You should most likely will have an ip that looks like this

ip address 192.168.1.10
subnet mask 255.255.255.0
default gateway 192.168.1.1 (usually the same ip as your router)

Sometimes the ip for the wifi network is 192.168.0.xxx

So unless you are trying to setup a 10.x.x.x Ip address network, your default gateway will give you problems.

Goodluck

The first check is to make sure the wireless radio is on in the notebook. You should have a wifi icon in the task bar. If it isn't there it means there are issues. On the network connection screen you should see the onboard network connection, and a wireless network. If you only show one then that's an issue. Run ipconfig/all from the command line and make sure you see 2 adapters, the wired and wireless. If there's only one the wifi card may be disabled.

Check that the notebook doesn't have a wifi off button (a physical slider on the side of the notebook) or possible accessible as a Fn key combination. I've caught myself out with this myself. Check the device driver section and make sure the wifi isn't disabled from there.

I hope this gives you some ideas to move forward.



The gateway is going to usually be the IP address of the router. If you can access the router you should check that. The IP config on the notebook should probably be set for DHCP (not a fixed IP) and the gateway IP of the router.

I just re-read your question and I think jwritchey is on the right path. That is an unusual IP address for your gateway, although I have seen bridges with that as range when unconfigured.

I'm not doing anything intentionally to set up the IP address. Could you tell me the steps to do that? I'm not too knowledgable on how to do this. Thank you!

Ok I just came back from Staples where I purchased the hp laptop and the tech support. They had no problem connecting to the internet in the store so it's not the laptop.

Well, I'm not sure. It is possible to connect to a local network but not get internet connectivity if the password is incorrect. Can you click on the icon on the task bar and make sure it forgets your home network and then try to re-connect to it again.

I guess I should also ask how old this notebook is?

UPDATE: I finally got on to the internet!! I disconnected from the homegroup and wireless network and rejoined them. Internet worked for about 40 minutes then I lost it again. I went on to the comcast forums and found that my router (which is their new one) is a bit of a lemon and drops wifi devices all the time. Most people had to get another router and bridge them and that solved the problem.

Btw comcast cust service was no help. People like YOU that give their time and knowledge just to help a stranger are the ones figuring this stuff out. THANK YOU!! You are appreciated!!!
