Really weak Wi-Fi signal - XPS 13 9350

Hey.

I just bought a brand new XPS 13 9350 (Windows 10. 64 bit) from dell.com, and opened it up.

I was so excited to get it going with it, which quickly turned out to so much disappointed to find out my 5 years old Samsung notebook has much better Wi-Fi reception than this one.

My signal strength on ALL the networks is so low, and even when I connect - traffic rate is not something I'd expect from laptop that cost that much...

I tried to update the last version drivers (Dell Wireless 1820A WiFi Driver, Version 1.555.0.0) to no avail...

Right now I'm really disappointed by the performance of this laptop. Any help will be appreciated.

Thanks.

RE: Really weak Wi-Fi signal - XPS 13 9350

Hi,

Sorry for the issues you've had with that system.   The driver you've installed is Version 1.555.0.0, A02, correct?

Check out this article and see if it can help you out:

Resolving Connection Issues on Your Wi-Fi Network for Windows 10

Since the Dell 1820a can handle both 2.4 GHz and 5.0 GHz bandwidth have you tried connecting on the 5.0 band to see how the connection is with that?  The system might be getting too much interference at the 2.4 GHz range and may work better for you on the 5.0 band.  

Also, try turning off bluetooth as a test and see if that helps improve your connection speed and quality.  

You said it's having connection issues with all networks.  Could it be that the antenna leads have worked loose during shipping?   Here is a link to the XPS 13 9350 Service Manual showing how to check the antenna connection.  

Try the resolving connection issues link above and let me know if changing the connection to the 5.0 GHz works better, as well as whether turning off bluetooth helps.   And if you can check the antenna leads to make sure they're snug.   To better help me troubleshoot this problem please click on my Dell Todd username and send me a private message with the Dell Service Tag of the system.  Please keep discussions about troubleshoot and steps taken here in this thread so others, who might have the same problems, can see what is done to resolve the issue.

RE: Really weak Wi-Fi signal - XPS 13 9350

Hi,

I have exactly the same problem like cheetah64D. I also installed driver version 1.555.0.0 and it did not solve the issue. Additionally, I can say that pinging the network using cmd (ping 192.168.1.1 -t) reports reponseless pings (out of time limit), sometimes up to 5 or more consecutively and of course I have practically no internet connection at this time. Other wireless devices connected to the same wifi have no problem to keep connected at these time point.

Turning off Bluetooth does not alter anything. Changing the property of the netork adapter Minimum Power Consumption = Disabled does not change anything.

I have to access PCs in my company via VPN. This is practically impossible currently and if I had not kept my five year old Zenbook, I would be lost now. I would really appreciate if there was a solution because otherwise it is a really good laptop. But if not I (or more exact: the company) will have to return it. I have bookmarked this page and also the support page to look for updates regularly.

Thank you for your support in advance!

Hi waschhaus,

I'm sorry for the issues you've been having.   You said you've tried the current driver but have you tried deleting that driver, rebooting, and seeing if Win10 has a native driver that might work better?  Or does it just end up installing the same driver version?

Also, have you checked the card itself to make sure it's physically seated correctly in the system, and that the antenna leads are tightly connected?

I'm curious, and trying to find out if there is a solution.   I've asked a few contacts here internally and if i hear anything I'll let you know.   In the meantime, to make it easier for me to provide information can you click on my Dell Todd username and send me a PM with the service tag of your system?   Please keep discussions and troubleshooting steps here in the forums

Hi Todd,

thank you for the rapid reply. At the moment and until weekend I am at a location that is so small that I cannot move far away (>5m) enough from the Wifi spot, so I cannot "satisfactory" reproduce the problem. But I can still see missing ping responses when I test from the most distant position (5m+1wall) in this flat. Next weekend I will try to follow your suggestion regarding deleting the Dell driver, but I am reluctant to open the notebook because in Germany this may lead to loss of guarantee.

Hi waschaus,

Are you in a situation where you can check for an update for the router's firmware?   Or are you accessing a public wifi?  It could be that the router needs an update to work with the protocols and chipsets used by the newer cards.

Man, are you seruious?? Are you offering me NOT to use the 2.4Ghz?? ALL the networks around me are at 2.4, what will I do with laptop that have only the 5 Ghz??
And what is this talking about the antenna leads? Am I suppouse to open up my brand new laptop and look for loosen wires??
I read all about this cr***py driver that supllied with this latop, and YOU KNOW it has nothing to do with all the above. This is all about the driver that DELL\Broadcom supllied here. So, please, get your **** together, and try to make better drivers for your premium products...
Jesus, and to think I spent so much money on this one, while I could get much better in cheaper price...
How did this laptop won so many reviews? That what bothers me. I can't stop thinking there was something wrong with all those review.
You buy so flattered laptop, just to find out you become one of so many 'frustrated from Dell' community.
And I didn't even started talking about the awfaul trackpad this laptop have...

Hi Todd,


I was able to reproduce the problem on many wifis meanwhile and when I search for wifis at home, where I typically see more than 20 with my Asus Zenbook (living at cross roads), I see only 5 with the Dell XPS. Like Cheetah, I also found this issue on many forums. The notebook was collected today by Dell service. I will let you know about the outcome.


Cheers,

Looks like others have had similar issues. You could upgrade the Wifi Card.

RE: Really weak Wi-Fi signal - XPS 13 9350

Thank you. I knew I can upgrade the WiFi card, but this is the biggest absurd, just right there - you're buying top-brand premium laptop - you don't expect to replace any part of it. After spending so much money on the laptop itself, you really shouldn't have any other 'upgrading' expenses...
