We may have found the culprit!!

I'll do some more extensive testing when I get back home tonight but after doing the following :
1. Disable True Gigabit routering under Setup/Internet/Manual
2. Change the SSID names for each radio, don't use the default names. Names can be anything.
3. Disable the Enable Graphical Authentication under Tools/Admin.
4. Set a NTP server under Tools/Time.
I can connect through teamviewer to my PC without any problem as well as run a speed test and get the expected results(Which never worked before since my dl speed would drop to 0 after 1 second).
I proceeded to undo the suggestions one by one and found that re-enabling True gigabit connectivity would make my teamviewer extremely laggy/unresponsive again.
I have no idea as to what this function does or why it would cause any problems - perhaps it does have something to do with my pcs configuration as well.
Hopefully everything will be good after some more testing.
Thank you so much for your time Furry!
