Geo Location Not Working

Hi, I am trying to use the wsop.com Nevada online poker website and I am continually unable to connect to their website due to them being unable to pinpoint my location (which must be inside of Nevada).  I played on this site for the last 2 months with absolutely zero issues and now all of a sudden I can not connect or sustain a connection the times I do connect (which is like 10% of the time).  I have friends in Nevada who are not having this issue.  I have reset my modem nearly 100 times along with uninstall/reinstall the poker software.  So, I suspect something is up with my router or on Cox' end because after 10 years of playing on this site this is the first time I"m having this issue.

Any tips would be appreciated.
