Re: different internet speed in debian and smart phone

[IL Ka]

Firefox browser in Debian. 

Internet speed checker is fast.com

Speed is 670kbps

 How do you connect your laptop to the internet? Is it a cable or wifi? What NIC are you using?

[kaye n]

Hello Friends!

My laptop, if it matters:

Kernel: 4.19.0-6-amd64 x86_64 bits: 64 Desktop: Xfce 4.12.4
Distro: Debian GNU/Linux 10 (buster)

This is a familiar scenario:

Firefox browser in Debian. 

Internet speed checker is fast.com

Speed is 670kbps

Built-in browser of Samsung phone

Internet speed checker is fast.com

Speed is 14mbps

I am quite sure I don't get this much disparity with another Linux distro, as well as in Windows 7.

Thank you for your time!
Kaye

Laptop connects to the internet using wifi.

NIC - are you referring to this?

result of inxi -b :
  Device-1: Broadcom Limited BCM4313 802.11bgn Wireless Network Adapter

ok, this is your card.

Lets see  output of 

$ iw dev [your_dev_name]

it should be 

 $ iw dev wlan0

I believe

Also, try to ping your wifi router ip address and some Internet address like

$ ping 8.8.8.8

Then, check https://www.speedtest.net/ : it gives a little bit more information than "fast.com"

Pardon me, but what should I type for [your_dev_name] ?

Hi kaye,

so the answer to your first question above is

(as root)
# iw dev wlp3s0b1

or

$ sudo iw dev wlp3s0b1

Because wlp3s0b1 is the name given by your kernel to
your Broadcom Wireless Network Adapter. And this iw command
should be run with superuser privileges as David stated
above.

Similarly, enp7s0 is the name given by your kernel to your
Samsung PCIE Ethernet card.

Also, when showing command output to people trying to assist
you, don't ever omit the actual command that generated the
output. Because it is a crucial aspect of the information sharing
process.

[kaye n]

Hello.

 This command,

sudo iw dev wlp3s0b1

resulted in a really long output that looks like a manual and started with this line:
Usage: iw [options] command

Really sorry, I'm not very knowledgeable with this.

Thank you for your time

Yeah, sorry, I just jumped into the thread half way and I didn't check
what you were advised to do previously (above), it is incomplete.

I think the output that they wanted to see would be given by these
three commands:
sudo iw dev wlp3s0b1 info
sudo iw dev wlp3s0b1 link
sudo iw dev wlp3s0b1 station dump

Already answered, I see. BTW …

Generally speaking when people give help of this list,
they often use the traditional names (eth0 and wlan0) as
placeholders for these interfaces because the newer,
persistent names are specific to your computer.

Here, I meant some sort of table of comparison, like:

Device connection down-speed up-speed site
type
Debian wifi&ISP nnn nnn fast.com
Windows7 wifi&ISP nnn nnn fast.com
Other linux wifi&ISP nnn nnn fast.com

eg

my mobile - 0 0 -

Reading this thread, remembering my annoyance with NetworkManager, I ran across this article by RedHat's NetManager developer Thomas Haller. From last year. Yes I suppose it's promotional, but he sorts thru some of the high-level issues that software like it has to address.

Whoever wrote this definitely likes to omit some details, and twist some
others. Few examples:

Note the absence of ifupdown, which is still shipped to paying Red Hat
customers.
Note the absence of ifupdown (same name, different implementation),
which is still considered the primary way of configuring network in
Debian.
And last, but not least, note the absence of netplan, which is the
primary way of configuring network in Ubuntu.

And the brilliant lumping of systemd-networkd along with the others,
while systemd-networkd was supposed to be One Standard Way Of Doing It
On Linux. Priceless.

Man's entitled to his option. Using a "stateful process" for a typical

On the contrary, in a well-designed container any means of configuring
the network from the inside are redundant at best. A good container
starts with the network that's configured already, and cannot change a
single bit of it while it's running.

I must me missing something, but NetworkManager on Debian does not
generate those wonderful /etc/sysconfig/network-scripts/* files like it
does in RHEL.


To sum it up - if NetworkManager works for you - more power to you.
If it does not - the thing was designed to be an over-engineered behemoth
(and the article admits it to a certain extent), you've got exactly what
was advertised to you.

Personally, I'll take "other solutions" designed with the "focus on
configuring the network" over the "configuration daemon that serves the
needs of applications". Because, while it may sound strange, I like my
network to be configured if I happen to do it.

It seems clear that NetworkManager like systemd was a response to non-dedicated, transient network configuration of a portable device or hands-off networking environment  (including physical layer). Naturally, we needed to build an all-encompassing software world-view on top of that :-) cause that's what we do :-)

Deities defend us.

My problem is the complete absence of thought shown by that list "server notebook workstation".

I want to ask him: What is a use-case?

Also to point out that containers too have different use-cases, and he seems to have done a mash-up again. You point-out one such case. I see at least three: what you might call cloud-temp, on-prem-in-broadest-terms, and human-at-workstation.

I have NM installed on my netbook and would have it on my Laptop if it
ran Linux. I wouldn't allow it anywhere near my workstation or server,
where it would have no function. And my workstation doesn't have a
static address, it has a DHCP reservation, like most other network
devices here. Only my netbook uses wireless and VPN, where I find NM
(now) Just Working (tm). Agreed, it wasn't always so.

On the subject of VPN, I'm having terrible trouble with the official
OpenVPN client for mobiles, it works on my Android phone but not my
wife's Android phone or our iPad. Possibly something to do with the
client on the latter two not having any manual configuration mode. NM
on the netbook is far easier to configure, which I believe Google and
Apple see as a drawback. It appears that nobody configures VPNs any
more, people just take a subscription with a commercial one and are sent
fully debugged configuration files.

Hello Friends!

This is an old thread but I think I may have found the problem and I would like to know your opinion.
As a refresher, my wifi speed on my phone is significantly faster than on my 10-year old laptop.

Could this be the reason?

from:
https://www.quora.com/Why-is-the-Wi-Fi-internet-slow-on-my-laptop-but-fast-on-my-phone
It could be the computer's Wi-Fi antenna. If the computer only supports 2.4GHz connections it will be slow. If it can use 5GHz but only with 802.11n it will be slower than a phone that has 802.11ac. Also the phone might use MIMO to increase its Wi-Fi bandwidth. Phones are usually upgraded more often than computers, so the phone probably has a newer, better antenna and support of newer faster Wi-Fi standards. 

If that's the problem, could this be a possible solution?

from:
https://www.quora.com/Why-is-the-internet-speed-on-my-laptop-so-slow-compared-to-my-mobile-phone-I-am-connecting-from-the-same-place-and-same-network
If you want to speed up your laptop check the WIFI adapter and if it is an older version buy a new wifi adapter with the latest WIFI (Wi-Fi 6, or 802.11ax today) - which will probably have to be an external USB dongle

Yes, but note that a wifi adapter can't operate faster than the
equipment on the other side -- they need to agree on a protocol.

It would certainly be worthwhile trying a new wifi adapter that
matches your wifi AP/router's specifications.

I don't see why the laptop aerial would be under suspicion. You wrote
"Wicd worked for a few days", and the aerial is unlikely to cause
that sort of variability.

But I think your paragraph above is the first (indirect) confirmation
that the phone is connecting via WiFi when you conduct your tests,
and aerial technology may make a difference, as might using a WiFi
dongle with a decent aerial attached. (That does prejudice its
portability, of course.)

We also don't know the favourability of location for the two devices,
and with wavelengths well under a metre, small distances can be
significant. Other traffic on the same channels is another factor;
though I am wondering why you're vague on 2/5GHz. Surely you know
whether you're using 5GHz just by checking the sessions in the
device, or even the access point (depending on how you configured it).

All that said, the speed measured on your laptop is so low that
I can't help suspecting you have something set up wrongly, or
some unfavourable circumstance. My 17-year old laptop can transfer
at around 18Mbps through its 2GHz WiFi. Now I'm measuring under
favourable circumstances: the router is on the floor of the room
above, and the source of the bits is scp from a local wired machine.
Obviously it would help with troubleshooting this problem to eliminate
(or separate) the factors involved, eg:

. browser use wget to download a large file from a "good" site
. internet copy a large file across just your LAN
. laptop disk copy a large file across just your LAN to /dev/null
. WiFi temporarily connect the laptop by Cat5 to the router

Well, purchasing decisions obviously depend on other factors, like:

. the results of the tests above,
. how bothered am I by the slow speed,
. can I find a less busy WiFi channel number,
. can I move the laptop away from microwaves/cordless phones/baby monitor etc,
. how long am I keeping this laptop,
. can a dongle get me off 2GHz for a mere £/AU$x,
. can I tether to the mobile,
. can I attach a Cat5 cable for those occasions when I need the speed.

Cheers,
David.
