This had worked for years on same router with no issues until tonight. Computer will connect to router but not internet. It will also however connect to ethernet and to my phones hotspot. Its like all the sudden it doesn't like my home router anymore. Router is Verizon Fios, computer a Dell Inspiron notebook with Win 10 64 bit. I tried to reboot router and computer multiple times, a few of the times it said connected only to drop connection again. Any help will be appreciated!
Update: Other devices in house work fine.
