I’ve noticed our Internet/WiFi is struggling occasionally.
Chances are, that's more likely your wifi settings / neighborhood RF interference. Do you have anything hardwired? Try plugging a laptop straight into the router and see if your internets is still struggling.
If it's still bad, visit
https://www.speedtest.net/, and record your speeds ~3 times, 2-3 times a day. (Make sure you're on wired connection for this!) Compare those numbers to the ones you're paying for (50/75/100Mbit up/down) and complain if you aren't getting at least close to what you pay for. If it's close, they aren't gonna do anything. But several factors off, you should get upgraded gear or switch to a cheaper plan. They won't do a refund. And make sure your numbers line up - Mb (megabit) and MB (megabyte) are 8x different!
If the wired connection is good, but wireless is not, do a web search for "router settings to improve connection" or "speed up wireless router". Changing your channel can easily help, since all your neighbors might be on the same channel (usually 1-11, or auto). Also, if it can, make sure your router/devices are using 802.11n, it might be set to 802.11 a/b/g, which are slower. Do n-only if everything you have still works. And there's a bunch of other little tweaks that can help, depending on how technical you want to get.
Thanks for the suggestions. We’re not at the hair-pulling stage yet, but you made a good point with the hardwire vs WiFi. It seems to be happening the most with the WiFi. Our router is from the Dark Ages...so it’s probably the culprit. Amazon Fire box is WiFi and we get those little pulsing dots as the device seems to be waiting for the signal. It has occasionally failed to connect. Wife also moves upstairs closer to the router with her laptop when she’s got all of her church friends on Zoom or whatever it is they use. There’s usually 12-15 doing bible study.
Thanks again...I’m gonna try those things you mentioned.
