MaaF supplied the D-Link G624T as their standard router for quite a while and all the necessary info is still in the support pages of their website. I did set up quite a few for referrals at the time, they worked fine on standard ADSL, no reason why it shouldn't on your ADSL2.
Maaf also supplied the Thompson around the time of the merger with Plusnet and give different set up instructions for routers supplied before and after the merger. The Maaf one was vanilla whereas the Plusnet one was customised. If your's wasn't supplied by Plusnet it's likely the MaaF instructions will be the way to go - that's if you need to bother with them!!
Probably prefer the D-Link personally, there are quite a few Maaf supplied ones in our village going strong although we are still stuck in the dark ages of 20CN so I've no experience of 21CN performance.
My LAN ports just died on me, however my best guess would be it's a similar problem.
Must change my signature sometime now I've jumped ship to Plusnet!!
