Wi‑Fi network problem: Nokia G-120W-F

Continuing the discussion from Connection instability: app to monitor the internet 24/7?:

Some days ago I wrote a topic looking for an app to monitor the internet because I was having trouble with my WiFi network. Since then, after some testing, I’ve started to suspect it’s the router (provided by my ISP). The comments in the original post suggested the same thing. But there’s been a development…

After swapping out my PC’s WiFi adapter, using an Ethernet cable, and some tools (see my comment in the original topic), the problem really does seem to be the router. It’s not handling the demand and keeps “bottlenecking,” not to mention when I lose the connection altogether.

I contacted my ISP, and they said everything is “normal” with the router. As was well suggested in the original topic, I got another router and connected it to the ISP’s router. And that’s where things get weird and go beyond my enthusiast-level knowledge.

I correctly connected my router, it worked just fine, and I disabled the WiFi on the provided router. However, I kept having the same problem! I’ve talked to the ISP via chat, over the phone, and by email (still no reply to that one), and they brush off the problem, saying everything is fine with the router!

Only YouTube works fine in full HD; for everything else, I have to download it to watch. And for stuff you can’t download, like Crunchyroll, I have to lower the resolution if I want to watch it.

I don’t know what else to do. What do you suggest?

It seems to me that even with a direct ethernet cable connection to the modem, the connection drops, right?

So the best course of action is to open a ticket with your ISP (or if you already have one, no need to open another), and then go to consumidor.gov.br and also to ANATEL. There, you report the entire issue: that your internet drops both over Wi-Fi and via cable. I’d advise against using overly technical terms—just report all the experiences you’ve had with the outages.

Once that’s done, you wait—they have to get in touch with you to resolve it.

No. It works fine over cable, that’s what makes it weird.

I’ll wait this week to see if they reply to my email. But from what I’m seeing, I’ll probably have to go down that route — but then it would be to cancel, not to fix it.

So only over Wi-Fi, both from the modem and from an external router? Then it might not be a problem with the modem itself, but rather an area with many signals all on the same channel. When you ran the tests, did you check that and set it to the least congested channel?

So it seems like your router, Wi-Fi adapter, or location/distance is the problem. If it works over cable (and that’s the best way to test to rule out the device/carrier), Wi-Fi can have many related and indirect issues that could cause problems.

See if there’s any free or less congested channel, there must be a crazy amount of Wi-Fi around…

Nope. :man_facepalming:t2: It didn’t even cross my mind! And if you’re interested, I’ll explain why below.

I downloaded a similar app, the highest rated one. Turns out, that wasn’t the issue—there was actually a Wi-Fi signal on the same channel as mine.

I went a week without Wi-Fi between canceling my old service and getting the new one installed. In that time, a new neighbor must have set up Wi-Fi! :joy: That’s why I thought the problem was with the new provider’s router.

Apparently, that was actually the issue. I switched channels, opened Crunchyroll, and it worked perfectly—no packet loss or anything. Thanks!

I mentioned this one because it’s one of the most reliable I’ve been using for about 5 years, the others are all poorly made copies. hahaha

It’s odd that it would drop with just one WiFi on the same channel. Take a look at the settings to see if the signal is in eco mode. If it is, change it to power or performance.
