Ok having just reset the HUB its now back into router mode and guess what can now sign it to it using both 100.1 and 0.1 the ui is laggy as hell and the setting wont save first time. good thing is the heat is no longer a issue after load pop I had yesterday. my speed is the same 150mb so no change ther only getting 85% of the speed I should. I have no words of what a mess this new hub 4 is . I just pressed the modem mode button stated it was saving it failed and then pressed save again and it did it this time.
