PPTPD VPN Connection Issues

[AustinJ]

I currently am using a vps/droplet from digital ocean with debian 7 on it. I obtain a install script from github to set up a pptpd server on debian because I am too lazy to attempt to configure one. The vpn works great when I am connected on my ethernet cable to our secondary router that then goes to our main router. However whenever I try to connect to my vpn with the exact same settings on my wireless adapter to my main router it gets help up on verifing the username and password. Any Idea what this could be. The main router doesn't seem to be blocking this in anyway, so this leads me to believe that it may be my wireless adapter and Windows Issue. On Linux using Manjaro 8.9 it is able to use the ethernet and the wireless to connect to the vpn just fine with no issues. With all this it must be a driver issue then?

Wireless Adapter: SMC WUSB-N2

 

Looking for possible issues since It would be nice to connect via the main router since the secondary and the ethernet are hammered down with internal traffic.
