Adhoc - connection 'stays' but ping fails shortly after

by chow_yee / June 14, 2007 7:31 PM PDT

Hi. I have tried searching this problem over the internet and this forum, would be really grateful if anybody could help.

My main home computer (Win XP Pro) is a desktop connected to a broadband internet service. Since there is a spare wireless USB adapter (Linksys WUSB11 v2.8), I used it to create an adhoc network so that those occasional visitors could connect to the adhoc network and utilise the internet.

I have a notebook with the Intel 2200BG running Win XP Pro and never encountered any problems.

Another (new) notebook running Vista Home Premium, however, constantly faces problems. It is a Intel 3945ABG. Whenever it connects, it will be fine for the first 30 seconds - I could use the internet or ping the home computer, and in Vista Network and Sharing Centre, it shows Local and Internet. However, after 30 seconds, the connection to the home computer always fails. There will be no more replies from the home computer by ping. However, it appears 'connected' - in Network and Sharing centre, it flunctuates between "Identifying", "Local only", "Local and Internet" etc.

What I have done so far:

1. All drivers have been updated to the newest.
2. All power saving features have been disabled.
3. I have tried both Auto-config (using DHCP) and manually assigning an IP for the problematic notebook, but neither solves the problem.
4. I have shut down the home computer, and created an adhoc network between both my notebooks. The same symptom appears (after 30 secs pinging fails)
5. Firewalls have been disabled for these purposes.
6. I have brought the problematic notebook very near to the desktop, but doesn't help either.

Any pointers will be greatly appreciated!!

I finally removed it from my network for similar troubles. Try something else. You might write back that it's not that part or something else but my reply is only sharing I tossed mine out.

No problem if Vista initiated it

Hi there, just an update to my post.

I discovered that there will be no problems if the Vista notebook initiated the Ad-hoc connection. So if the Vista creates a new ad-hoc network, and the desktop computer (XP Pro, also acts as internet gateway) connects to it, the connection will be magically very well.

But if the Windows XP Pro Desktop computer initiated the ad-hoc network, and the Vista notebook connects to it, the problems arise.

For convenience - is there a way to make the connection work if XP initiates the ad-hoc network?

Thanks!

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
