modem keeps crashing

[ Edited ]

In the last week my modem has been crashing daily and locking up so that only power cycling the **bleep** thing will restore it.

Re: modem keeps crashing

I suspect that the "crashes" coincide with the T4 timeouts.  You should report this.

 

You can post a help request on the VM support newsgroup, who are 2nd line support techs and will respond quickly to you. It beats the offshore debacle by a long mile.

 

If you're on XP, the VM web site tells you how to connect to the newsgroup using Outlook Express (Outlook doesn't support this).

 

If you're on Vista or Windows 7, you would use Windows Live Mail (a standard part of your system). To get on the VM Newsgroup you need to be operating through the VM broadband system.

 

In Windows Live Mail, you'd click the "Newsgroups" link at the bottom of the screen and then Tools/Accounts then Add/Newsgroup Account.

 

Give your Display Name (like SAURON), your e-mail address (which can be fictitious) then your server address for the newsgroup which is "news.virginmedia.com".

 

You'll then be able (via the Newsgroups menu item) to select the Virgin media icon on the left of a search panel, click on "All" and wait a few minutes till it's finished listing thousands of newsgroups.

 

Scroll down to "Virginmedia.support.broadband.cable" and double click it.

And you're there. You can post your stuff including any evidence you've collected.
