Its possible that you may be able to reset that router to facotry defaults or even a partial reset may work,
Not all WiFi is satellite and the above thread pretains to that, if you dont have satellite then try these
First try turnning off the computer then the Router/Modem ... unplug the modem/router for a full minute. Then boot things up and see if its reset itself.
If no this one may loose any rules you have set up in the router so be warned you may have to re add those.
Fine the small button or way of resetting to factory defaults in your instruction manual, there is normally a small hole the size of a lead pencil that your menat to fine a small instrument and push this in for usually 10 seconds some are different and you may have to see your owners manual for your model to get this right.
Then restart everything and readd your rules and settings.
