can network speed depend on installation?

RudraB · 07-27-2011, 03:40 AM

friends,
probably this is the most idiotic question and probably i know the answer. But I want to get confirmed.
Is it anyway possible that my mobile broadband speed is slow because of my installation is wrong?
actually, I formatted my machine and make it dual-boot. In both the cases, I have f15 installed. After that my mobile-broadband speed is horrible slow. I installed (a)kmod-wl and as dependency, broadcom-wl but my lspci only shows intel network manager.

Code:

$ lspci|grep Network 
17:03:00.0 Network controller: Intel Corporation Device 008a (rev 34)

can this be related or just coincidence?

To your question YES.

For your nic, looks like the broadcom isn't showing. Check /etc/modprobe.d/blacklist for broadcom.

I use b43 instead of broadcom-wl, which works fine, but you need firmware.

broadcom in not listed in blacklist:

Code:

$ cat /etc/modprobe.d/blacklist.conf 
#
# Listing a module here prevents the hotplug scripts from loading it.
# Usually that'd be so that some other driver will bind it instead,
# no matter which driver happens to get probed first.  Sometimes user
# mode tools can also control driver binding.
#
# Syntax: see modprobe.conf(5).

one more thing that I should mention: my wired and wireless network (in office) is working fine, only the mobile broadband that i use in hole is giving problem.
May it be due to the effect of windows drivers that are installed?

business_kid · 07-28-2011, 03:02 AM

There is something called 'fast ethernet switching' or similar on many laptops in the bios. If that is set (SOUNDS like a good thing) it disables the wifi if the nic is brought up first, and vice versa. Check that out.

I generally hate people giving me lists & printouts, but look at these 2 lines from dmesg

That's a thing you can do something about. Fix that

Quote:

It seems like you've got RH's NetworkManager. Make sure you're not also running /etc/rc.d/init.d/network. chmod -x there, please.

NetworkManager comprises a gnome bit using oddball libraries and modules from here & there (e.g. egg-dbus) and a startup rc script, which is a red hat replacement for the network script. Read up on them. They are written up. That's one of the reasons I run Slackware - it DOESN'T have NetworkManager.
