I just upgraded my internet to a faster speed so i could play online lag free and now cant chat due to nat type error. ive searched this and see there are 3 fixes. the 1st being to open ports on my router, well i didnt have a docsis 3 router of my own and they had one to rent so i got it and now dont have the username or passphrase for my router. so i called my isp and they said they cant change port settings for "security reasons" and my ip is dynamic and they wont change it either..
so my question is; has there been a fix for this besides adjusting port settings, or is the only solution to buy my own router?
