Net Problem in linux distro's in my laptop


Having installed new Linux OS in my laptop, I found that the net speed was quite low when compared to windows 7 on the other hand.I am very enthusiastic to use Linux OS but these kinda issues obstruct my interest towards open source operating systems.Do find a solution for my problem.Google loads very well but when coming to other sites, they load very slowly most importantly facebook and yahoo. I got the same problem in UBUNTU 12.10 and installed Linux Mint the next time, still the problem exists...Please gimme a good solution for my problem. I use wireless internet.Lets think that this issue is due to my net connection but the same websites loads perfectly in windows dual boot in my laptop.

Hello dsrikarreddy, welcome to LQ,

it would be good to find out if it's a problem with the drivers or the configuration. Please open the dosshell in Windows and execute the command
Code:
ipconfig /all
afterwards boot Linux, open a terminal and execute the commands
Code:
ifconfig
and
Code:
cat /etc/resolv.conf
and
Code:
sudo iwconfig
and
Code:
lspci -k
post all output here. The output of ipconfig from Windows will help us to compare the configuration with those of your Linux system. The output of lspci in Linux shows us your hardware and which drivers are loaded.

Markus

Yours laptop is in an local network supported for one wireless device?
Can be interesting that you try the WIRED connection to compare speeds, even that in windows you able to get a good speed in wireless mode.
This can help the find where is the problem.

Anyway, below there a good site to teste your connection speed if you need.

aceleron, don't confuse the OP, he/she wrote
Code:
I found that the net speed was quite low when compared to windows 7
which means that wifi works with Windows properly but not with Linux, in this case one has only to compare the settings in Windows and Linux and check if Linux uses the appropriate drivers (module).

Hi, the problem seems to be that you don't have the correct nameserver configured for Linux. Windows uses 192.168.0.1 which probably is your router and wireless accesspoint. Because 192.168.0.1 is your DHCP server but the nameserver isn't correct you should check if you have your Linuxsystem correctly set up to use DHCP.

You can check if the problem is really the nameserver when you edit the /etc/resolv.conf file and put a line
Code:
nameserver 192.168.0.1
But this will be overwritten while next reboot. But with this setting the internetconnection should be better as before.

Outputs after editing

@markush
These are the outputs after editing the /etc/resolv.conf file....After reboot i could not find nameserver 192.168.0.1 even after editing before the reboot....Also there was no significant improvement in the net speed..

You should read the documentation of Mint carefully and find out how to configure DHCP correctly! When everything is correct your Linuxsystem should use the same nameserver as Windows does, namely 192.168.0.1

Well, I saw that Mint has a file /etc/resolvconf/resolv.conf, probably one could change this file. But as I wrote above, read the documentation and understand how they configure for DHCP and for the nameserver.

Referring to the Mint documentation, Mint configures for DHCP by default, so it should work, did you change any networksettings by yourself?

Well, I think I can't help here, I would recommend to use the report button at the bottom of one of your postings here in this thread and ask a Moderator to move this thread to the "Linux Networking" forum here at LQ: http://www.linuxquestions.org/questi...-networking-3/

Probably there has anyone an idea.
