Patch download disconnections

I keep having trouble downloading the latest patch. For some reason it is causing disconnection issues within a few minutes and a " reset router" message pops up I am connected thru USB ports and have had no problems in the past. I was considering searching for my old LAN card cable and using that port. Otherwise the only thing I can think of is to uninstall SC entirely and reinstall.
MY router is an ASUS RT-N66U double 450MbpsDual N Band Router I purchased last year.

The kicker is that my wife does not loose her wireless connection for her Nook or tablet during these download periods.
