Do I need to change wireless settings for new ISP?

  cyberphobic 11:24 04 May 2009

My mother in law is in her 80s and lives 150 miles away. I have set up a wireless network so that when any of her children or grandchildren visit, they can take their laptops and go online. Orinally the ISP was Tiscali and I set up a D-Link router modem which worked well. I then realised that because I have O2 mobiles I could get a much cheaper broadband deal with O2 which I have now done and the changeover has now been been completed. My wife is visiting next week and will have some work to complete online so my question is whether the wireless network settings are specific for each ISP so that I will have to re-enter O2 settings or should the network still work regardless? O2 have provided me with a new router/modem but presumably the D-Link will still be fine.

Plenty of real experts on this forum who can answer better than me (or is it I?) but I do not think you need to alter router settings. my wife has Sky BB in a house that is used for holisday lets and as long a the visiting laptops can "see" the router a new connection is made.

If you continue to use your existing D-Link Router and have simply reconfigured it to connect to the new ISP, without altering the "wireless" settings, then computers that connected wirelessly before will still be able to connect.

Wireless settings are not specific to an ISP. A wireless connection emulates a conventional ethernet cable connection but over a radio link, using standard protocols (802.11g, 802.11n etc).

mgmcc - thanks for your reply. The bit which I'm not clear on is exactly what I will need to do to reconfigure it to the new ISP. I have been told that all I need to do is to enter the WEP code which I received with the O2 modem/router. Does this sound right?

The "WEP code" you received with the O2 Modem/Router is *ONLY USED* to connect "wirelessly" to the O2 Modem/Router.

If you continue to use your existing D-Link Router, then any WEP or WPA key currently used will remain unchanged. Probably the only change you need to make in the D-Link Router's settings will be to enter the new O2 Username and Password.
