My ISP says I need a new router after having problems lately with my 20 year old Linksys WRT54G.  I think it's having issues keeping up with everything I now have especially since we started streaming Disney+,Netflix, etc. 

I need one that will run at least a couple of TV's at once, plus someone browsing the internet.  Has to have enough range for a 2 story house.  The linksys would cover the whole house, but now it just can't keep up.  I get on my chromebook, or wifi on my phone when someone's streaming and it's dropping me off frequently.  Every once in a while it will freeze the TV.  I'm getting plenty of speed coming in, I just need it to get from the router out.
