Back in December I received a free Roku streaming stick with a Slingtv membership and I use it on my living room tv. A few days ago I decided to buy two more streaming sticks. One for the bedroom and one for the kitchen. The two new ones are getting poor signal strength, while my original one is getting good signal strength. I tried rebooting both the router and roku units, but no luck. Then I figured it had something to do with the location of the router in relation to the roku units, so I took the one with good signal strength and put it on the other tvs and took the poor ones and put them on my living room tv. They each had the same strength as before, so I would assume that would rule out the router location. None of the units have the wifi extender. They all show channel 6 as their wireless channel. I'm not really sure what the problem would be.
I tried changing channels, first 1 and then 11. No change. I wonder if it is a router problem? I figured since I moved the units around to different televisions and the connection remained the same that ruled out the router, but I really can't think of anything else. My router is getting up there in age (over 10 years old) so maybe it needs to be replaced.
While I don't disagree about updating the router, you've got a working setup as is. I am surprised, though, that the Express is showing better signal strength than the Sticks. If I saw that with my devices, I'd be curious myself.
But, I have to ask. You say "poor signal strength." Are you actually seeing a difference in performance? That is, do you only know that because you looked at Settings > Network > About ? If you didn't see that the strength was different, would you know?
If not, I would hold off on spending any money, unless you simply feel it's time. Or find a heckuva deal. But, it's your setup and your money. What I would do might not match what you would do. If your current setup is working, it's a matter of want, not need. But "want" is always good enough if you got the money to spend.
Sorry about the Express/Stick thing. You wrote Stick, but then the "Free with Sling TV" changed it in my head to Express, since that's their current offer.
Yeah, with a performance issue, I'd consider upgrading a router that age. Personally, I went with the Google WiFi 3-pack when they had it on sale. Setup is easy and the mesh covers the entire house easily. But, if a single wireless point would do the job, no need to spend the extra money. Even the cheapest today are better than just about any 10-year old router, so you're looking at an upgrade in performance no matter what you do.
