Wireless Connection Issues: XPS 13 9350

Question

Hello,

I am having wireless connection issues, mostly on my home network, where the laptop will show that it is connected to the wireless access point, but that there is no internet connection. The issue is resolved by running the Windows troubleshooter, but it will often persist a few minutes later. The problem that the troubleshooter identifies is "The default gateway is not available."

It seems to work better when I am at a different location (work, coffee shop, etc.), but the issue is not solely limited to my home network. All other devices work fine on the home network. I have uninstalled and re-installed the network drivers numerous times.

I'm hoping that the answer is not a new wireless card, as this laptop is becoming almost useless at home.

Thanks.

Some information:

Dell XPS 13 9350, Windows 10

Dell Wireless 1820A 802.11ac

Driver Version: 1.566.0.0

Hi Steelboom,

Thanks for posting.

Have you been able to run the Support Assist diagnostics?

Download and run SupportAssist

1. Download and install SupportAssist
2. Click Start > All Programs
3. Navigate to Dell > SupportAssist and launch the program
4. Once SupportAssist launches, click on Checkup > Scan a Specific Device
5. Under Communication Devices > Select Wireless Card (Requires a connection to a wireless network)
6. Restart the system after using Support Assist.

Robert, Thank you for responding. I followed your directions and the SupportAssist did not identify any issues. The hardware scan showed as 'passed' after running it on the network card.

I will try with to test with other devices turned off. However, we have other computers and devices that access wirelessly without issue. So if it's a bandwidth problem, why would this computer be the only device affected?

I have not tried wired at home, as that is not practical given the location of the router. That said, I have used a wired connection elsewhere, and have not had connection issues.

If it's passing the diagnostics, then it's possibly the bandwidth at your home location. Have you tried it without all the other devices going through the router?  How about wired as opposed to wifi?  Does it improve wired?  If so, it's probably not the card.

I am posting a new item related to speed throttling on the XPS 13 when on battery. Just mentioning it here in case that is a factor for you.
