Reliance broadband and wifi problems



hey guys ,
so heres the thing .... i had been using my reliance broadband connection - thunder 599 1 mbps - for the last 1 year and had been using it with a Netgear wrn613 router ,
2 days back the reliance connection had stopped working- i.e dsl light was steady on and not flickering and so i had called the company and they said that it would resolve next day- and it did but the wifi stopped working - and after a whole lotta configuring the netgear router - its finally comedown to this - i can only access the router via my laptop - cant access it with my android phone or ipad which earlier was not an issue
i have dhcp on if that helps
have been stuck on this for a day now and would really appreciate the help
