Windows 7: Wifi and lan problem possibly homgroup related

hi this has been bugging me for months i can transfer and copy things stream etc from my tower to my laptop but i have to use ethernet leads i have a tenda ws480 v2.0 wireless router my tower is connected to the router all day long just wish i could stream access stuff from it wirelessly to my laptop i can accsess the internet fine i just cant concect to the tower all its hard drives are set to share and visa versa. any ideas any one?

First off, probably a bad idea to share harddrives if your OS is included in this group.

To use homegroup, click through the tabs at the top of this site for a how-to: HomeGroup from start to finish - Help & How-to - Microsoft Windows

If you are having another problem, please let me know as it was unclear in your first message.

there all on the same home group its just the minnute i unplug the ethernet i lose all connection to the home group just the internet acsess remains ive tryed all the home group trouble shooters i can find an still nothing really i have tried before ive asked this iam normaly pretty good with pcs been using them my whole life

So they don't work in a homegroup wirelessly is what you are saying. But both computers can still connect to the internet wirelessly, just not each other.

Do this tutorial: SFC /SCANNOW Command - System File Checker

Then make sure windows is completely updated on both computers, and make sure they have the latest wireless adapter drivers. If you need help, let me know what both adapters are called and I will look them up for you.

Also, without the wired connection, use wireless to, once more, ensure that both computers can indeed connect to the internet.

yeah only the laptop has wireless and ethernet the tower only has ethernet and is connected to the router. thanks for taking the time to help by the way.

Okay is there only 1 modem router combo or a modem fed into a router

confirm that both computers can connect to the internet at the same time if the laptop is using wireless.

did you follow the tutorial I provided?

Is windows updated on both computers?

Perhaps when the laptop switches to wireless, it becomes a 'public' network. Go here: Control Panel\Network and Internet\Network and Sharing Center

You will see a computer and monitor with your computer name under it. Right below that it will say 'network', and tell you if you have a home or public network. Click it and switch to HOME.

Did you try this: http://windows.microsoft.com/en-US/w...troubleshooter - worked for me last time I had trouble.

its just a modem router its a tenda w548d

havent tryed the othe one yet but i did the one in the qoute and still nothing along wiv everything else.
