#225292 — question concerning wifi and connection

[Multipart message — attachments visible in raw view] — view raw

Hi

For some reason wifi is too slow or connection gets interrupted or
downloads get stuck. When switching to wireful connection problem seems
resolved.

Also on a few cases when connecting through public wireless with a
password, after switching off the wireless connection the connection
refused to come back. On another occasion, the gui wireless menu did not
work. command nmcli wireless radio on did not work either. Any ideas why
that might happen

Wifi is generally going to be slower than a wired connection. Wifi is
subject to device contention as various devices sharing the channel each
struggle for bandwidth. There's also, sometimes, the issue of shared
channel interference if there are a lot of wireless access points around
which will cause some access points to back off and reduce data rates. Wifi
is often just slower: [Divide roughly by 10 for Mbit to Mbyte conversion] -
54Mb wifi (best case) == 5.4MB per second. 100Mb wired (best case) == 10MB
with no device contention. Many wifi routers now have 1Gb wired links (best
case) == 100MB.

Public wifi portals with a password - you're on your own - they all work
differently.

For the future: You may find it useful to use Wikipedia / a web search
engine to read information on some of this before you come and ask
questions on a mailing list. If you can show that you've done some reading
/ tried something out for yourself before asking a question when you don't
understand, it can help other people help you more easily.

All the very best, as ever,
