Router

Am thinking of buying a TP-LInk TD-W951ND router..Any comments on these ?

I'd edit your first post to edit the Title and add the TP-Link model number to the title, you may get a more knowledgeable response more quickly.

I assume you mean the TD-W8951ND.
I've no hands on experience of the Tp_link models but they do seem to offer value for money.
The TD-W8951ND is only a Wireless N-Lite router and so wireless performace is not going to be great.
If cost is a main issue then I'd look at the TD-W8960N or TD-W8961ND instead since they offer full Wireless N
If you can stretch to a bit more ( or maybe thinking of fibre at some time ) then look at the TD-W8970, it has Gigabit ethernet and the capability of a WAN port for fibre use.
BTW noting your other post http://community.plus.net/forum/index.php/topic,115077.0/topicseen.html , PlusNet will supply you with a new router ( TG582n ) for the cost of postage ( £5.99 ) as long as you stay for another 12 months. Some people have experienced poor wireless performance with it though.
Hope that helps
