Dell 9370 Killer WiFi 1435 Issues and Problems

Hi there

Has anyone got any fixes for the Killer WiFi 1435 lag issues and slow performance and what workaround have you taken.

Totally interested in that thread !
Huge drop of internet performance navigation on my new XPS 15 (with killer 1535) (coming from Intel 6235, using same network)

 

Seems like the best move is to buy the intel card and install it. Since I'm getting mine in a few weeks I'm going to just do that right when it comes in. Such a ridiculous thing only dell would do on a high end laptop.

 

Which Intel card do you recommand ?

 

Edit: got the wrong model

Intel 9260 AC seems to be the one of choice, seems like a very cheap solution to one of the annoying quirks with these. I plan on adding this, a new SDD in time, and a repaste to mine if everything goes well after the first 30 days. I will do the wifi card regardless since its fairly cheap and easy to remove and return if i decide to return the dell.

You can't replace the wireless card in the 9370

 

I would try uninstalling all of the killer software and just get the .ini files from the killer website, not the suite.

Here is the download link:

Im realy sorry I misread this at 9570 folks, apologies! Off to a nice start here

 

I talked to my contact at Killer about this; the latest BIOS update should fix this issue in the XPS 13.

 

The other issue is the Wi-Fi just doesn't work after resuming from sleep mode sometimes - you have to go through the network troubleshooter to fix it (or reboot).

Having the same issue here. Already sent back 1 XPS 15 9570 and upgraded to the i9 9570. Same issue with poor wifi connection using killer 1535. First XPS 15 9570 Dell sent a intel card but didnt have much luck with that. Hoping for a resolution on this 2nd 9570. Looking forward to a solution.

 

Odd, I don't have any issues with my killer wifi in my 9570, or the intel 9260 that I am trying in it.

 

all of my other devices, including another dell laptop do not experience this. Wondering if maybe a router/ modem issue?

 

Hard to say, the fact that you tried two totally different wireless cards and two totally different laptops makes me think something is going on. Is it just a slow connection or issues connecting?

 

Slow connection and sometimes hard to connect to unless within 10ft of router/modem. Further away of 20-30 ft and it is minimal speeds. If I put my other devices same distance(20-30ft)there is no issue with wifi range/speed.

When I got the first 9570 I thought maybe antenna was bad.

The thing is, If I am within 10ft, I am getting full mbps of 120+.

 

Reset your router lately? Which router do you have?

 

It is a CISCO DPC3941T which is what Xfinity supplied me with.

 

There was a recall on that wireless gateway due to "performance issues." Call comcast and have them replace it.

 

Thanks for the info. I have a Netgear coming and will post the outcome.

 

There's a new BIOS 1.4.0 that claims to fix Killer Wi-Fi stability issues. It also adds keyboard backlight timeout settings in the BIOS for battery & AC use (Finally!)

I will check also to see what bios version is on my 9570. I also just installed a Netgear 6250 router/ modem. But still experiencing some range and speed inconsistency.

I am going to trouble shoot router position next.

 

Fixed router position and all drivers are updated...killer wifi, bios and fresh install of win 10 with current 1803 update. Still poor performance.

 

So my resolution to all the issues I am having....Returing this laptop! Numerous BSODs, Dell unable to fix wifi issue and quiet frankly their tech support is horrible. I really wanted to keep this thing but I have spent more time troubleshooting then actually usuing it for what I bought it for.

 

Did you ever get a new router instead of the known bad one?

 

Yes I put in a new router (Netgear C6250) and no improvement. Actually, that router ended up being worse ...so that is going back as well. I think what pushed me to the edge to send this one back was all of the random shutdowns and BSODs...and Dell not wanting to do anything about it accept charge me more money to look into it. I understand if I had the laptop for a month or so and then issues start showing up...:but less than a few days of receiving it and nothing but issues.

 

Makes sense. Sucks you've had issues, was really hoping the router was the cause. What are you considering next?

 

either a MSI GS65 or Gigabyte Aero 15 x 4k. Any other recommendations?

 

I like the gs65 but the new razer actually looks nice...​

 

Well I talked myself into giving it a 3rd and final shot with a 9570 I9. I have since returned the Netgear C6250 and put in an Orbi which is awesome! Now I will know the wifi issues are not on my end. Once the new machine arrives I am hoping for the best with wifi and now BSODs.
