15.6 - connection speed way down after uogradd

I’ve reloaded my USB key with Leap 15.5. Prior to the ‘upgrade’ my laptop WiFi @2.4G was running at 150 to 200 plus Mb/s on a 500Mb/s ISP download ‘speed’.
After the ‘upgrade’ i5 dropped below 100 in the area of 50-80 Mb/s.
Any ideas why?
This is not acceptable. I will put Leap 15.5 back on and live with the EOL & hope a fresh install of Leap 16 works better when it releases.

BTW, I opened Win10 on my laptop and it had connection speeds of 200 plus.

Which tools or ways do you use for verifying the up/download speed on linux?

Tried on mine (15.6 GA on a Dell Latitude) … 579.29 mbps download and 438.78 mbps upload.

SpeedTest++ via CLI, A GUI speed test I found in Discovery. Various speed tests on the internet. Fast.com, Oklaa , speediest.net etc.

You didn’t say what is your laptops WiFi rating ( 2.4G,5G, larger?).

If I hook up with Ethernet, my speeds are 500 plus, but I don’t have a 100 foot Ethernet cable nor an Ethernet hub for both laptops we use.

My Dell Latitude 5500 connects at 5 ghz wi-fi. Technically, the laptop is connected to an AT&T “extender”, so I’m not directly connected to the Wi-Fi Gateway (main modem) in the house.

Internet ↔ House Gateway ↔ extender ↔ laptop.

Many folks don’t know what a wi-fi extender is. Our property is very large, so not all wi-fi devices can reach the main Gateway, so extenders are placed at the outer perimeters of the main Gateway … our extenders are “connected” to the main Gateway via wi-fi, not Ethernet.

We use Ookla for speed test.

Still it is 5G. Where as my laptop is only 2.4. I really don’t need an extender since the machine is never mor3vthsn 25 feet away from the router.

I may have not made it clear that I did connect directly to the ISP’s modem, and the speed was drastically slow.

We are off topic here since I was look8ng for things in Leap 15.6 that may help speed it up.

I’m NOT suggesting you need an extender

I only mention that because an extender degrades Wi-Fi performance. No change from when I was running 15.6 Beta to 15.6 GA now.

Be that as it may, I’ve realized ZERO performance with Wi-Fi connectivity.

Just providing a 3rd party perspective :+1:

Hi Bill

You should really start by sharing your wifi hardware details, as that could be relevant here…

inxi -Nna

What does iwconfig report about the quality of your wireless connection?
/usr/sbin/iwconfig wlan0
Note: You may need to substitute the device interface applicable your system.

Sure. I have new memory cards coming for the laptop eraly this week.
Then we’ll see after that if network is still at 68Mb/S on a 500 Mb/s line.

I know the memcards will not speed up the network but it should make the machine perform way faster so I’m not watching snail progress.

That output shows a reasonable/usable signal level and corresponding bit rate (physical layer rate), in line with your reported speed testing results. Remember that this bit rate will be higher than the data throughput obtained at the transport (TCP, UDP) layer due to the overhead involved in wireless connections, headers, data retransmissions etc. You would need to be closer to the access point in order to have higher signal quality (higher received signal levels between devices).
