I tried doing this.
Power cycle your home network.
If you have been able to connect with others before, and this issue only recently started, power cycling your network may allow you to connect with others again. To power cycle your network:
Unplug the power cable from both the modem and wireless router (if separate from the modem).
After 30 seconds, plug the power cable back into your modem and wait for the lights to remain steady.
Plug the power cable back into the router and wait for the router lights to remain steady.
