I recently changed from an ADSL supplier to ADSL2+ from O2, which use a Thomson router. I had never previously used ADSL2+ or an ISP-supplied router, so I was a bit surprised to find that I did not need to enter a username and password into it.
Does this mean that these details are pre-configured by O2 or does ADSL2+ not use them?
I ask because the wireless reception is not as good as I'm used to, so I may replace it with a router of my preferred brand (Draytek). If I do so, will I run into any problems with configuration and/or compatibility?
Their own routers have a back door, that lets them update the router remotely and that is one reason, I won't use it.
For example, when they recently changed their DNS routers, rather than tell me the truth via an email they sent me, they assumed they could update the addresses automatically and simply said we will be updating your router in the next couple of days. I knew they couldn't because they don't have access to my equipment.
Result? I lost connection due to them changing the DNS routers addresses and ended up having to call them to find out what was going on.
While the help desk techie was excellent and knew straight away what the problem was, (I suspect he'd had a few more calls about the same issue) it was annoying.
You are still misreading my question. I know how to configure routers, but this has nothing at all to do with router logins. It is about ISP logins. I am used to ADSL ISPs that issue an ADSL user-name and password. For example, my last ISP used the account name plus phone number for the ADSL user-name. But O2 does not have this (as far as I can see) and I wanted to know whether any other router would expect me to have such data, as my previous routers always did. At least, from the other answers, I know that other routers will work with O2.
