Wireless ground to a halt after yesterdays update.

[warren3]

Hi.

I have an update yesterday which required a restart. Since then my wireless has crapped out. I get a signal and the first page loads up in the browser. After that all I get is a spinning circle and pages take an age to load.

I did change my wireless PCI-E card last week from a Realtek to Intel 7260. I didn't reinstall Ubuntu or anything I just changed the card and booted up and it was fine. Since the update though it is not working.

Any help would be appreciated.

If you boot an earlier kernel from the grub menu. Does it work better?

Hi.

I am going to try than now.

Thanks.

Hi.

Yes Wifi is working fine on the old kernel.

So you say you put intel in?

Let us see

lspci -nnk | grep -iA2 net

From old kernel and new

Hi.

Old kernel


02:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 73)
Subsystem: Intel Corporation Wireless-N 7260 [8086:4062]
Kernel driver in use: iwlwifi
03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c)
Subsystem: Gigabyte Technology Co., Ltd Motherboard [1458:e000]
Kernel driver in use: r8169


New kernel


02:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 73)
Subsystem: Intel Corporation Wireless-N 7260 [8086:4062]

03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c)

Kernel driver in use: r8169

Just to make sure I take it the top kernel in the 'advanced options for ubuntu' is the latest kernel my system has?

Thanks.

[carl4926]

Yes

Both have the driver loaded correctly though

Hi.

It seems to be working now! All back to normal! I don't know what happened there. But now I have another little strange problem. I seem to have another option in GRUB that wasn't there before. I dual boot with Windows 7 and now I have a 2nd option for Windows 7 on sda. It seems to have appeared after using an old kernel. Do you know why it has just appeared?

Are you sure it hasn't always been there.

What are your partitions?

sudo parted -l

[warren3]

Hi.

Here is it:

Model: ATA WDC WD5000LPVX-2 (scsi)
Disk /dev/sda: 500GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos

Number Start End Size Type File system Flags
1 1049kB 500GB 500GB primary ntfs boot


Model: ATA Crucial_CT120M50 (scsi)
Disk /dev/sdb: 120GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos

Number Start End Size Type File system Flags
1 1049kB 90.0GB 90.0GB primary ntfs boot
2 90.0GB 120GB 30.0GB extended
5 90.0GB 112GB 21.5GB logical ext4
6 112GB 120GB 8504MB logical linux-swap(v1)


For Windows 7 I boot off sdb which still works fine. The 500GB drive that is sda is blank and is just for data when I get around to putting all my FLAC files on there, so it is strange this has appeared. It was definitely not there before.
