Hubby and I cant play together either... AND to top it off, we cant access our own router we have to contact the cable company to get a lvl 3 tech to do things
Turn on every wifi device in your house then locate the Mac Address for each device and write it down and what it is for. Contact your cable company ask them to list all devices showing, see if any are missing. When you confirm alll devices show have them assign perminant IP addresses to all devices and set number of users to number of devices showing. Once that is complete , tell them you want to set up gaming for your device and they should be able to work that out for you .I port forwarded for my Xbox1 one and have had no problems with glitching or otherwise since then. It is possible your router is not sufficient to support multi person gaming. Hope this helps
or you can just add all of those into your router the only MAC address the ISP needs is my modems.
What most likely the reason could be is that the router is not performing its function correctly or it could be a security feature on the router or computer
A step to find the cause is to make sure both computers can connect to online play (testing one at a time) if one cannot you have already narrowed down your search
If they can both connect make sure they are being given separate IP's (I had a D-Link that had DHCP enabled yet would not do it)
Make sure your router firmware is updated to current (I had issues with this until i updated)
