Wifi signal strength dropped to 2 of 5 bars

    I disabled the virtual adapters. What are all these other adapters showing up?

    still trying to boot in safemode. Followed all the steps but on restart my screen comes up with my selections (ubuntu 12.10, advanced options Ubuntu 12.10, Windows 8 bootloader on sd4,Windows 8 bootloader on SD5). Luckilly I have the bootloader on SD4 to fall back on because after the changes I made to the bootloader on SD5, it just sends me into a loop no matter which mode of Windows I choose. Eight of Safemode restarts the computer and takes me back to the screen where I can choose from Ubuntu or Windows.

    I installed Ubuntu first, then Windows so I guess it's the linux boot manager screen that comes up. Have no idea how to rectify this at this point. Still need to boot into safemode to see if wi-fi problem persists.

    Yes dual booting with Windows 8 is terrible, I would think about using system restore at this point.

    Based on all the responses it seems pretty clear.

    Restore the system. If the problem still exists then you're wifi adapter is shot.

    Well, Spiderbite. I am in complete agreement that a system restore was the next step. But I'm a scorched earth kinda guy. Instead of a system restore, I just formatted the entire hard drive, and reinstalled Ubuntu 12.10 x86_AMD 64 bit, and Windows 8 64 bit, since I have a dual core 64 bit processor and like a coward, I went with the 32 bit versions of the two operating systems.

    I appreciate your help. The Linux 64 bit is up and running beautifully, and the wifi situation is unchanged. I believe you're right about the adapter being tits-up. I haven't played with the Windows 8 side much yet, but both systems boot, and connect to the internet. The rest is a piece of cake.

    I love the forum support process that's become popular. Beats the heck out of trying to talk things out with some overburdened tech at a call center. You guys are great.

    Discovered the real cause- bad connection to Wi-fi Adapter


    Tightened the two screw holding the wi-fi card in place a quarter turn each. Guess it wasn't grounded properly.

    Problem solved.

    Hi there

    Although you seemed to have the problem sorted remember the following :

    Physics 101. You are talking about a WIRELESS signal -- as anybody with even the tiniest smithering of Physics can understand any sort of wireless signal will be subject to interference from any number of sources varying from other wireless devices, other radiating devices such as Microwaves, or even changes in the standard Atmospheric pressure -- when the old Analog TV signals were around for example on some really strange days I could even get some TV signals from Russia several thousand KM away.
    Note also the quality of the Wireless receiver in your PC will also count -- even the same models aren't identical so one computer might show 100% signal while another a 66% signal.

    Even such things as the power delivered to your wireless card can cause the signal to vary.

    The most likely cause though is other wireless systems or increasingly 4G mobile phones being used nearby -- note the fact you can't SEE other networks doesn't mean they aren't there -- a lot these days HIDE the SSID so you won't see them.

    In Europe the 4G signals are either on the old analog TV systems - around 800 - 900 Mhz or on the 18-1900 Mhz band which in some cases can cause interference with the 2.2 GHZ of the older wireless systems --- if you can change your router to the "N" system you should get a lot more interference free reception.

    If all fails you'll have to get a Wifi extender --this will usually swamp any local interference. However with 3 bars the signal is still perfectly useable.

    Cheers

    Is there a solution to this problem. The same thing happened to me, all of a sudden signal strength degraded from 5 to 1/2 bars. Have tried replacing the wireless card, re-installing the driver but to no use. PLEASE HELP!!!

Suddenly, this afternoon my signal strength has dropped to 2 of 5 bars and I only see 2 or 3 other networks.

    I have made no changes to my modem, laptop or physical location of either. My room mates laptop is working normally and he has 5 bars and still sees 8 other networks. Any suggestions. If something has changed a setting somewhere on my laptop, would a system restore change help? I can't live with a weak and unstable internet connection.

    Can never rule out the router. Many posts online about the signal going south on older units.

Hi, So iwas wondering if there is a way to check the signal strengh of your wifi by percentage. Thanks
There seems to be almost no correlation to performance - 5 bars could be a 100+ Mbps connection, or it could be < 5 Mbps... On the other hand, 4, 3, 2, and 1 bars all mean that the connection is going to be flaky and unstable :rolleyes:
