Though this might appear to be a serious problem, it really isn’t. And that’s what we’ll do here as we’ll show you how to get around this issue. Don’t worry because whether you’re a Windows user or Mac user, we’ve got your back!

Doing a power cycle might also do the trick. This is the easiest and (sometimes) most effective way to get around the problem. This clears the accumulated cache in your router.

When it comes back online, reconnect your modem to your router and wait for it to go online.
