Slow wireless connection

I have an internet provider that allows internet connections up to 50Mbps. By testing ( or ) I can get that speed when my computer is connected wired to the router.

However when I do the same test through wireless I get no more than 10Mbps. So it must be the wireless that is slowing everything down.

I have an Inspiron 17R and according to lspci with

01:00.0 Network controller: Intel Corporation Centrino Wireless-N 2230 (rev c4)

I have this package installed in my Fedora 23 Package ipw2200-firmware-3.1-11.fc23.noarch. Do you know I should be using another firmware?

In fact, I find two problems that could be related:

1) From this Fedora system I can't see the 5GHz signal of the router. 2) When I connect to the 2.4GHz signal, the speed tops at 10Mbps (when I expect 50Mbps.)

Are you able to boot from a LiveUSB/CD? If so, see if you get the same results. If you do, it may be hardware; if not, we can examine other possible software issues.

If your firmware works, there probably is no better one. Just keep your Fedora updated. Looking at (good resource for linux wifi stuff) it looks like there is no more recent firmware update than your 3.1 version

If you live in a densely populated area (some people living less than 100m away from your wifi access point) they are probably using the 2.4GHz band too. Overlapping bands often degrade speed. This is a common issue with wifi, not related to any firmware.

What you can do:

  • try using cable instead of wifi
  • buy hardware that supports 5 GHz
  • reduce the distance between your wifi device and access point
  • maybe find a better place to put your access point at. There should be some note on that in the manual.

The excuse of the company is that I am connecting with the 2.4GHz and not the 5GHZ, however I can't see that signal at all. Isn't the fact that it is Wireless-N mean that I should be able to pick up the 5GHz?

No, wireless-N doesn't mean it can use the 5 GHz band.

@genodeftest Ok, I found it the documentation says 802.11b/g/n 2 x2 and 2.4 GHz . However it also says "Delivers up to 300 Mbps speed in the 2.4 GHz band with multiple streams for enhanced speed while improving coverage and reliability." but mine tops at 10Mbps.
