After quite a bit of research, trial and error related to why my Wifi Network slows to a crawl or stops when mining ETH on Claymore Miner.
Long story story short, I started using the Ethermine Pool and for whatever reason, I am now able to mine and surf the web, watch Netflix on other computers etc.
I just resolved this all last night.
Hope this helps some folks.
i had some problem with it too, but it was totally different.
after few hours using claymore's, my connection was unstable for a day
