Windows 10: Wifi very slow on laptop, but ok on other devices - Windows 11

Hello, I have a new Dell XPS with i7 processor running Windows 11. My wifi speeds have been painfully slow. I have 300mb bandwidth but average 20mb on my laptop and sometimes much less. While all my other devices average 250-200mb. Any recommendations? Thank you.

Wifi very slow on laptop, but ok on other devices - Windows 10

Hi Annu

I've had the same problem as Panayiotis1984. Upgraded to Windows 10 on my Lenovo from windows 8.1 - now the wifi is painfully slow. The wifi still works fine on my other devices (smartphone etc).

I tried the steps that you suggested but they did not bring an improvement.

Any other suggestions?

Michael

 

Wifi Very Slow

Hi,

The following are some reasons that may cause of the slow WiFi connection.

• Corrupted or incompatible drivers.
• Missing updates.
• Network connection settings.
• Hardware or software problems.
• Inappropriate distance from the router or obstruction.
• Interference with other devices.

To isolate the concern, have you checked if the issue persists with other devices? For now, we suggest that you follow the troubleshooting steps provided in this
article.

 

Win10 Wifi slow and erratic, IOS and Droid devices OK

Fafhrd -- thanks for the suggestion. I disabled IPv6 and re-booted the Surface. At first I thought BINGO, because on re-conection the speed was the best I've seen -- 40 mbps download. It stayed that way for maybe an hour or so, then deteriorated (getting maybe 10 - 15 mbps), then went back to dead (.2 mbps, or perhaps 1 mbps at times). So no joy. But thanks again for the info and suggestion. As I note below, it goes unpredictably from dead (.2 mbps) to OK (10 mbps and above).

Ken -- Thank you very much for the follow up. Not sure about "shut off everything below WI-Fi sense" -- I do not see anything similar to "wifi sense". Below is a screen shot of my wifi adaptor settings. It is unchanged from what I started with, except I have disabled IPv6, per Fafhrd's suggestion (see above).

Yes, the IOS and Droid devices are connecting to the exact same SSID (SUNSET HOUSE).

I cannot find a free Inssider for Droid, and I'd rather not pay the $10 for something that may or may not solve the problem. I am about ready to admit defeat, and just continue using my iPhone hotspot.

I find the wholly erratic nature of this to be maddening -- I will think I've fixed it, then back to molasses. Even from click-to-click I can tell the speed is varying dramatically. Something is "confusing" Windows. Perhaps it is some sort of transient interference as you first suggested. I would think the adapter itself is bad, but it is fine with the iPhone hotspot (and it was fine when I left home). And the router itself must be fundamentally ok since the IOS and Droids are fine.

Two last items I will toss out:
1. When the speed is dead, I cannot even get to the local router url (10.0.0.1). In other words, even response time here locally, what I think of as the WAN, is bad. Its not just to/from the wider web. When I'm in "molasses mode", I have to log into the Router Admin from my Droid. Whatever is causing the slow response is affecting access to the router just 30 feet away. Maybe I just don't understand how urls like 10.0.0.1 are resolved -- maybe they still have to go to "the internet".

2. I keep looking at what is different between the way the iPhone hotspot shows up, versus the router. Below is a screen shot from another wifi analyzer (called WifiInfoView). The security for the router says "WPA-PSK + WPA2-PSK", with a "Cipher" (whatever that is) of "TKIP+CCMP". That is different from the iPhone hotspot, and it is different from every other network that shows up on the analyzers (I did not include them in the screen shots). The iPhone and all the other access points show security of "WPA-PSK" or "WPA2-PSK", but not both. And all the others show Ciphers of either TKIP or CCMP, but not both. I wonder if this is a difference in this router that is ok with IOS/Droid, but confuses Windows.
In any event, thanks again for your time and help.
