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

Thank you for your time!

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.
