Computer cannot connect to network

Wed May 23, 2018 10:40 pm

The service is through Spectrum, the router is a netgear. Chipset is a Dell wireless 1705 802.11b/g/n 2.4 gighz.

I've gotten my phone, my wife's phone, the smart TV, and the laptop all on the wireless network, but my desktop either does not see the network, or it sees it, and after I put in the code, fails to connect. I've tried uninstalling and reinstalling the drivers (after lugging it to the damn router and plugging it in via ethernet cable).

Any suggestions past that?

Ooof. Is there some Dell software trying to handle the connection? I find those type of programs often cause more issues than they really solve. Also, is this a PCI/PCIe card? Maybe try reseating it just to be extra sure ("reseat" it regardless of what connection it has IMO).

In any case (and obvious this is not the first option), but it may be worth your time and money to upgrade that thing. Something with at least both 5GHz and 2.4GHz might be nice. A couple options below.

Has it ever worked before? If so, what changed?

Do you have another wireless AP you can hook up to the network to see if it is a compatibility issue between the Dell and the Netgear? Also, sometimes updating the router/AP to the newest firmware will fix weird compatibility issues.

Beyond that, yeah I agree with the post above mine -- a new wireless card would be the next thing I would try.

5GHz wireless has been around for a while, even on 802.11n. Are you sure that your router is also outputting a 2.4GHz band for your Dell to see? I just set up a new 802.11ac router for our house this week, so I freshly remember that the 2.4GHz and 5GHz broadcasts are completely separate networks that devices connect to. The cheapo $40 webcam we use for a baby monitor cannot detect the 5GHz wireless band.
The suggestions that DancinJack provided are fine as long as your router is 802.11ac. If not, you can get by with cheaper 802.11n wireless cards.

I've never used the wifi on this before; at our last place the drop for the cable was right by the computer desk so I just used an ethernet cable.

The router is outputting a 2.4 ghz band.

I tried connecting a 5 ghz USB wirless adaptor and the computer didn't even seem to recognize that (borrowed it from my SIL).

I guess in the grand scheme of moving this isn't too high up on the PITA meter but jeez!

Well, when WiFi fails, bring the cable to you with Powerline. I bought this kit for $20 and it's been working flawlessly for the past 9 months. Before that I had this 200Mbps kit that I bought for $20 back in Jan 2014 with nary an issue either. That 2014 one had one unit with coil whine that finally broke my sensitive ear's tolerance after 2.5 years.

As in, it didn't even prompt to install drivers? Nothing in Device Manager? That's seriously weird if so.

I had to reinstall Win10 on a co-workers' laptop this week. The internal WiFi chip is fried (cant turn it on) so I've got him using a Linksys USB WiFi dongle. When formatting, Win10 install didn't seem to notice that the internal WiFi wasn't working (I think Win10 sees the chip, but the chip is blind/deaf), and it also didn't care about the USB dongle. Ethernet wouldn't turn on, even after a restart (sometimes Ethernet gets hibernated). Even after I rebooted and re-plugged the Linksys dongle, it showed up in device manager, but Win10 made no effort to even install generic drivers for it so I had to use a different computer to download the driver pack off Linksys' website, transfer the contents to the laptop via USB and install the drivers manually in device manager......PITA.

TL;DR Check device manager for the USB Wifi dongle.

Yuck. That sounds almost like the "bad old days" of trying to get network/WiFi drivers working in Linux. Kinda lends support to my theory that all desktop and mobile OSes seem to be converging on a common level of suckiness.

It shows up as a generic PnP in my device manager, and it gives me the *ding* sounding alert, but there's not even a prompt to install drivers and it doesn't show up in my networking connections:? I may use the laptop and see if I can dig up the drivers for it and dump them on a flash drive...I hope I can find them, god alone knows how old/well supported this thing is.

Sounds like UEFI hook for the airplane mode switch might be garbling things? Many laptops have the WiFi+BT on a separate M.2/mPCIe card. If the laptop can be opened without too much fuss that's a good reason to find out...and pull the offending device, if you can.

finally got something working; I hooked up via ethernet again, and managed to find updated drivers for the USB wifi adaptor on Netgear's site and that's working. My intergrated wifi for the desktop still isn't and I'm giving up on it at this point. I'll buy my SIL another adapter to replace this one.

If you're out of options on the desktop's integrated WiFi, and you've tried everything sensible to do with hardware config, drivers and IP address - try netsh winsock reset as a last resort. It's an old Windows 10 bug that may have resurfaced.

Is your PC that cannot connect running Windows 10 on a Microsoft Account?
If so, that may be problem.
I tried to share my files to my family with multiple computers, and the only one that cannot connect (Password incorrect) even though it is correct and connect to all the other computers in the house.
The only thing different about the one that cannot connect is Microsoft Account Windows 10.

Yeah, the first time I serviced it for him, I suggested a nano adapter like this since they're <$10 and it was the easiest out for me. He bought one, but it died (surprise surprise), which then led him to the current $40 USB stick which he doesn't like because it sticks out a lot further and he's worried it will break off. I wish I would've known he was considering the $40 USB stick because I definitely would've steered him toward replacing the internal card instead for the same price.

It does seem to be stuck in airplane mode, but I can't coerce it out of that mode for the life of me. That made me wary about replacing the internal card and having the same problem, hence the USB suggestion.
