Problem with wifi on ubuntu 12.04, intel centrino 130n

The Samsung 350U2B laptop is intel hm65.
Wifi works out of the box (Intel itself says that the drivers for the wifi built into the kernel version is older than 2.6 what that is), but it works only few minutes (don't know from what depends). Then writes that otsoedenilis, simply can not to any site to connect! In ubuntu 11.10 there is a similar problem, but was solved by disabling the N mode of the wifi in 12.04 didn't help.
Maybe somebody can help? I want to go to 12.04, the battery on it lasts longer newer kernel (with better support for Sandy Bridge) and generally nicer.
In Ubuntu 11.10 the iwlagn driver in 12.04 don't remember

I have a problem like this was because of the crooked configured so pci c rt2000, as the driver: hostapd. The problem: the firmware is working with the curves algorithm adjusting the transfer speed/latency. After some time, the accumulation of delays is the locking, package cache. I helped restriction is allowed to use speed, then a reduced rate of "beacons" all were selected by a method scientific tyka. If this problem is on all access points, look for information in the logs, describe the problem padrone.
what are the logs? Problem with 12.04 tests only at home on the N point( asus n11 ), which cannot be cut down this N mode (or b/g/n or just n).
11.10 behaving oddly even with my fix, in my network and the other works well, and the girl at home on the router AirTies 4450 is not working can I say...
Nepodskazhite where you configure the settings you described? - Cassidy27 commented on October 8th 19 at 01:06
They are configured on the side so you can dig in the settings wpasupplicant. I really did not climb, as in other points the laptop behaves correctly. Show me the output of "lspci | grep -i net" and then look at what your controller is saying. - Herminia.Kuhic commented on October 8th 19 at 01:09
01:00.0 Network controller: Intel Corporation Centrino Wireless-N 130 (rev 34)
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06) - Cassidy27 commented on October 8th 19 at 01:12
See if there are any messages from the kernel or driver during problems: "cat /var/log/kern.log | tail -100" - Herminia.Kuhic commented on October 8th 19 at 01:15
Yes, Realtek s this is a common glitch, I also have a problem with them (TD runs)... wpa-supplicant won't help, we'll see what we can do. - Herminia.Kuhic commented on October 8th 19 at 01:18
So Realtek is the only Ethernet, isn't it?

"cat /var/log/kern.log | tail -100" to score under 12.04 after developing problems? - Cassidy27 commented on October 8th 19 at 01:21
Yes, it is advisable to recruit immediately so that the logs are not clogged with debris-you will see the last 100 rows. Show another configuration: "sudo iwconfig" - Herminia.Kuhic commented on October 8th 19 at 01:24
iwconfig view before and after freezing, are there any changes? - Herminia.Kuhic commented on October 8th 19 at 01:27
now I can't say for sure, but I think in 12.04 my signal was lost (mean 0 dB) while the network Manager and wicd was all OK, 12.04 at the moment I can not start the evening :) - Cassidy27 commented on October 8th 19 at 01:30
then it is better on soap write semen@sam002.net - Herminia.Kuhic commented on October 8th 19 at 01:33
