No internet access after 22.5.2.15 update - Windows 7

Hello

After receiving the update 22.5.2.15 , my Windows 7 64bit PC has no wired internet access whatsoever !   It worked fine previously with the nice old version , but the horrible update has royally messed up my PC.   I have tried repairIng the connection and NIS has tried and failed to correct the no connectivity issue  , and I have work to do but cannot do it .  Whoever released this garbage should be fired .   Why release a half baked product to paying customers ?    I don't know what else to do , I have tried the  removal and reinstall tool  but it says no internet and fails .  I have no internet access at all thanks to Norton .  Please help .
