Internet intolerably slow

Post by Howard_P » Tue Oct 08, 2019 5:40 pm

Hi- This post is a follow up from a previous one on Aug. 22 of this year. At that time the problem was intermittent and is now almost continuous. It used to work just fine. In that thread Pjotr suggested this:

Try this:
https://easylinuxtipsproject.blogspot.c ... .html#ID11
(item 11)

And make sure that your wireless network meets the following requirements:
- WPA2 Personal
- AES only (no TKIP)
- SSID visible
- optimal channel (preferably fixed, not dynamic/automatic)

Explanation:
https://easylinuxtipsproject.blogspot.c ... urity.html
https://easylinuxtipsproject.blogspot.c ... html#ID1.6

I was able to do the things in the easylinuxtipsproject but to no avail. I had no idea whatsoever how to do the bit about the wireless network, and I still don't.

Hi,
Its a nice fast computer.
But, what internet connection do you have? Whats the bandwidth?
Have you tried using a wired connection (with ethernet cable into the back of the router)
Have you tried going to Starbucks to see if internet is slow there also?
What happens when you try going to a speedtest site? ie, https://www.speedtest.net/
There might be lots of different reasons so we need to go through each option to see what the problem is.
Yes, it is a process.

With 4G / LTE my provider promised me 54Mbits (corresponding to 6.75MBytes) maximum data throughput. It's nice that I already broke through the 8 MBytes limit at Central European bedtimes (technically, that seems to work...).

At the main TV time (from 5.30 a.m.) the local dominant landline distributor - the former national one - breaks down regularly - I then serve my customers with 4G data described above - reliably...

Smartphone Sony, lowest middle class - but waterproof...

Time for a USB Panda. Intermittent to failing now.
All things go better with Mint. Mint julep, mint jelly, mint gum, candy mints, pillow mints, peppermint, chocolate mints, spearmint,....

I'm sorry but I don't understand the last 2 posts. My carrier is Comcast, my download/upload speeds are about what they've been for a good long while, Download Mbps 147.74 Upload Mbps 5.95. My wife's windows computer, using the same connection is running perfectly...Thanks. -Howard

If your stated upload and download rates are actually guaranteed at all times, I don't understand your problem - it's fast enough.

I run devices under Linux, macOS and Windows with my smartphone and under the same operating systems I also see the described bottlenecks in so-called "fast" landline connections.

The upload and download speeds come from the online speed test, and they are what I always get with that test. Thanks for your effort -Howard

How is your wifi signal strength? On Mate, when you click on the network manager icon with the wifi enabled, you will see the list of detected wifi network with graphic showing the signal strength. Or you can run nmcli dev wifi in Terminal to get the same thing. If you are getting consistently low signal even if you are close to the access point, there could be hardware or driver issue.

Thank you. What would a low signal look like in nmcli dev wifi? This is what I got:
howard@howard-ThinkPad-T440s:~$ nmcli dev wifi

That is good signal strength with maybe 25MB actual speed. Whatever the problem is, it is not hardware or antenna.

Thanks. If it's not hardware or antenna and the signal is good that seems to leave only software. I wonder if I upgrade from 19.0 to 19.2 would that potentially set right what is not working? -Howard

Nothing to lose to upgrade and may help. Your hardware is pretty mature (not too old to be deprecated and not too new) and should have good support with the 4.15 kernels.
