SpeedTouch 330 ADSL Modem

SpeedTouch 330 ADSL Modem When connected properly to a live broadband connection there should be two steady green lights on the modem. If the left hand green light is steady and the right hand green light is flashing then there is nothing wrong with the PC but the modem cannot see a live broadband connection. That could be because: 1. the phone line is not actually connected to the modem 2. the ADSL filter is fitted wrongly so that it is blocking the broadband frequencies instead of passing them. 3. the line is not connected to broadband at the exchang...

Cable (DSL) Broadband USB Connection

Cable (DSL) Broadband USB Connection I went to install a wireless router in a cable broadband connected house. I was surprised to find that the current connection between the cable modem and the customers laptop was via a USB cable. (The customer’s laptop did not have an ethernet socket) This made it difficult to configure the router because it only had ethernet connections for both modem and hard wired PCs. And the wireless was disabled by the default factory settings!

Not having digital cable in my area means that I don’t...

Setting up Cable Broadband with a Router

Setting up Cable Broadband with a Router Don’t try to set up a new installation with the router connected between the cable modem and the PC.

User names etc are requested by the set-up program.

Sometimes you will have to “spoof” the MAC address of the PC that the installation was set up with onto the router - see my tip: Broadband router not connecting to NT...

Broadband Disconnects

Broadband Disconnects A client reported that a USB broadband modem performed well when browsing the internet but as soon as he attempted to download anything more than about 2MB it either disconnected immediately or sent the error message "Tapisrv has caused an error in rpcrt4.dll and will now close". A reboot was then required. This error has many possible causes. Quite a lot of people have this problem, especially with Windows Me, but Microsoft has not documented a fix for it. Some cynics have suggested that you need to upgrade to another operating system. There is another possible solution. Sometimes this problem can arise through incompatible settings for the TCP/IP configuration parameter called MaxMTU. By default, Windows uses a value of 1500 but PPoE, which is used by most ADSL...
