Wi-Fi signal keeps dropping/fluctuating

So, here’s the situation: for about the last month, my connection has been acting completely haywire. My router sits out in the hallway while my computer is in my bedroom—we're talking maybe 15 to 20 feet apart—and for two whole years, everything worked flawlessly with a rock-solid signal. Then, out of nowhere, things just started falling apart. 🤔 I’ve already tried swapping in a different Wi-Fi router and even tested a different USB Wi-Fi adapter, but the result is always the same. Honestly, the only thing I can suspect is some kind of signal interference. Ever since the tenants downstairs set up their own internet about a month ago, my signal has been wildly inconsistent; sometimes it just drops entirely, leaving me unable to load a single webpage, almost as if something is actively blocking it. I tried mounting the router higher up, but that didn't really do much. Is it actually possible for their setup to clash with mine? It feels strange because for two years the signal was perfect without me moving a single thing, yet everything remains exactly where it was. I even gave a TP-Link router that a technician brought over a shot, but it was the same story—it might work fine for thirty minutes or so, and then suddenly the speed plummets like something is jamming the frequency. Resetting the router provides a tiny bit of relief, but that's about it.

What kind of options am I looking at here?

Should I invest in a beefier Wi-Fi USB adapter with an external antenna, or perhaps move over to a PCI Wi-Fi card?

I mean, maybe there really is something interfering with the signal, hmm.

As I’m typing this, the signal is actually showing as "excellent," mostly because I nudged the router slightly, but the whole thing is just so temperamental. It never used to be like this; it was always steady and reliable.

Last night was a nightmare; I was down to a single bar and it took me half an hour just to get a single page to load.🙂

Now, it seems fine again.

My gut feeling is that something is definitely interfering with the signal. It might just be a massive coincidence that this started right when the neighbors downstairs got their internet installed, but considering I'm barely 15 feet from the router and had two years of perfect service, it's hard not to connect the dots. Everything went downhill the moment they plugged in their router. 🙂

Should I just ask them to turn their router off for an hour so I can see if my connection stabilizes? 😁

It’s a bit hard to wrap my head around the idea that they could be causing this, but I'm honestly stumped as to what else it could be.

Then again, there are times when the signal stays good for several hours at a time, and everything runs smoothly for most of the day.🤔

It’s totally possible that your router is fighting for airtime because other nearby routers are blasting signals on that same channel. I had this exact headache last summer when I moved into my apartment in Chicago and couldn't get anything to load; what worked for me was just jumping into the router settings and manually switching to a different channel to clear out the interference. Give that a shot and see if it stabilizes your connection.

Just a heads up though—don't just bump it up one notch, like moving from channel 2 to 3. Since those adjacent channels overlap, you won't actually see any improvement. You gotta make a bigger jump to really clear the interference.
Also, keep an eye out for things like cordless phones or even your microwave. They run on similar frequencies and can absolutely wreck your connection if they're too close.

So, it’s been running flawlessly all morning—I've got all five bars and the speed is actually decent—but last night I was stuck with just one single bar and couldn't even browse the web properly.

I poked around in my router settings, and I'm wondering if this "select channel manually" option is what I'm looking for?

There are 11 different channels listed here, and honestly, I haven't the slightest clue which one to pick, though I think I've settled on channel 3 for now.

Oh, wait, I just caught that—so I should probably aim for a higher number to ensure there's enough of a gap?

Check your PC to see which channels the nearby routers are sitting on, then just pick the one furthest away from any of those strong signals near you.

I’m not entirely sold on all these other routers out there, but honestly, things have been running pretty smoothly for the last couple of days 👍 and the signal strength seems solid. I did notice that sticking to channel 6 or 7 works best for me, though I run into this annoying little quirk where I’ll manually set it to channel 6, hit save, and everything looks fine—only to check back later and find it’s jumped right back to 7. Then, by the next morning, it’s decided to revert to "auto" mode all over again. It’s just this constant cycle where no matter which channel I pick, the thing decides to switch itself back to whatever it wants after a few hours.

I've currently got this USB Wi-Fi adapter

Since my router is sitting pretty close to me, I don't think I really need anything more powerful, especially since my current setup used to work flawlessly without any fuss. That said, if I really need to grab one with an external antenna, I can easily pick one up at Best Buy, though I suspect the interference from the neighbors might still mess with me occasionally—maybe just a little less than before. 🤔

In your router settings, under "select a channel manually"
...it’s set to auto. Can't you see that?

So, which channel are you going to pick? You'll just have to test them until you find one that actually works...

Look, I think you missed my point entirely; obviously, I know how to use the "select a channel manually" setting, because believe me, I speak English just fine 😁 but here’s the kicker: I’ll set it to channel 7, and it stays there all day, but then I’ll step away, come back online the next morning, and find it’s jumped right back to channel 3... even though I distinctly remember locking it at 7, because I always double-check my work.

Anyway, for the most part, everything is running beautifully. My only real gripe is that around midnight or maybe an hour into the early morning, the signal tends to dip slightly down to about four bars, but overall, it's performing quite well enough.

One more thing—do you think this USB Wi-Fi adapter I'm using is up to par? 😉

How would I even go about doing that?

The inSSIDer Home software

On my end, when I'm sitting on channel 6, it’s like there isn't a single soul around, and my link score is sitting at a perfect 100. 👍
