This is along the lines of a quick tip that I didn't find anywhere near widely reported on-line. If you replace your WiFi router you don't necessarily have to go through the process of reconnecting every WiFi device in your home.
Over the last several years we have gotten several WiFi devices, which of course have been connected to our home network. In some cases, for example with my aging Brother printer, I have no idea where the manuals are anymore. In other cases, like with the Blu-ray player & Roku devices, how you connect to a network is fairly plain & simple, but it's nonetheless painful to enter passwords [for WiFi access] using a remote.
One solution to that is pretty simple -- that may in fact be why I didn't find it all over the web... Use the same name [SSID] & WiFi password for the new router as you've been using for the old one. All of your devices should not see any difference, connecting as usual with no fuss.
Now after writing that I have to say that there is one potential wrinkle to this... Most WiFi routers on the market today have 2 WiFi frequencies that they use, 2.4 GHz & 5 GHz -- devices will connect using one or the other, but not both. The oldest, and sometimes the cheapest devices can only use the 1st frequency. WiFi routers generally use one of two methods for connecting to these 2 frequency ranges -- either the band with the stronger signal is chosen automatically, or you in effect have two WiFi networks, one for each range.
Being able to choose the frequency yourself, by choosing which network name [SSID] to connect to, is a more reliable way of getting the throughput you want/need -- automatic selection doesn't always make the best choice -- but that means a new network name, & entering the password to connect to it, for some of your devices. Choosing a router that makes that selection for you means that you don't have to choose which frequency band gets your old network name -- and so everything WiFi should still work -- but you might not get the best WiFi performance with every device in your home. Connecting at 5 GHz gives the Roku in my bedroom the best data rate for streaming, but in that bedroom the 2.4 GHz signal is strongest, so in that case I *think* the manual selection works out best.
At any rate, while I personally don't recommend buying one of the more expensive routers on the market, since new WiFi standards are coming & you'll want to buy another router soon enough anyway, new router models means good sale prices on the slightly older ones, so now might not be a bad time to take the plunge if like me you had an old single band WiFi router.
