Wanting to replace Superhub, need some tips.

I'm wanting to replace my Superhub with something better. However it has a coaxial input. And last time I checked a lot of routers only take in RJ-45 inputs.

Are there specific routers I'm supposed to get? My friend who replaced his Superhub said he just used a normal router and it worked fine but my seems to use a coaxial cable going into the wall...

Anyone else replaced their Superhub with something better?

Something which has a stronger Wifi connection. I been having trouble to connect to a few servers recently (eventhough they are online I see them as offline). I don't know if my superhub is busted or not but Virgin Media are very annoying when it comes to telling a technician to come down... The servers will be randomly unavailable and few hours later it will be available again... Its been happening for awhile and its getting very frustrating so I'm assuming it might be the superhub...
