I have had lots of problems with DSL-2780 cannot connect to my ipad unless in same room as router.

I have TVPlus  which I cannot connect to because the router is not good enough,  Requested a better router when I agreed to a further 12 month contract.  Had lots of phone conversations about settings rebooting etc.  Bottom line is when I accepted tvplus in the first place the deal was that talktalk would supply a router good enough to run the service - they have not done this just updated my old router which didnt make the slightest difference.  In the end I lost the will to live you just round in circles.  I have been with talktalk for 10 years and I am now losing patience.
