Why does 10.8 take so long to discover Wifi networks?

I've noticed recently that it takes a very long time for my MacBook Pro 6,2 OS X Mountain Lion 10.8.2 to discover WiFi networks.
I open the laptop up, or wake it up from sleep, and the wifi takes 30 secs to more than 1 minutes to find any WiFi networks. It doesn't maintain the connection to the network it was connected to before the last time it went to sleep.
The WiFi icon in the upper left has no bars, all greyed out, nothing moving. When I click on it, the context menu that drops down just says "no network selected".
Interestingly, if I turn WiFi off, wait a few seconds, then turn it on again, it works fine, connects very quickly.
Is anyone else having these problems? I would very much like to get this resolved. I primarily use my computer for webbrowsing, so when I open it and have to sit there for a minute before any networks are found, then I have to go in and select my network, it becomes very frustrating.
Thanks

IPhone 4 (ios 4.0.1) won't "remember" wifi networks

It makes me log into my home wifi network every hour or so. It's like it loses the connection, then "Forgets" about the network.
I have to go into settings->wifi, select my network, then put the password in all over again.
Anyone else see this?

I was having this problem too recently with my new Clear Spot device. When I'd have security on, (WPA) I would always have to enter the password and it would not remember it for whatever reason. At my home network, and my mom's place, it would remember. I did the reset network settings as you guys suggested and it appears to be working now. Will test again tomorrow at work where I use my iPhone to control all my slideshows with the Clear Spot at my router... Thanks!

Droid Maxx Won't Forget WiFi Network

Hey all,
I just upgraded to a new Droid Maxx and I'm running into a frustrating problem. I configured a wireless network at the office (a limited guest network) and connected to it just fine. I then got connected to the full permission WiFi network and I decided to drop the guest network. I went to drop the WiFi network from WiFi - Manage Networks - Forget and it worked. Temporarily. I came back a few minutes later and it had reconnected to that guest network (which requires a password) and that guest network appears in my list of networks when I go to Manage Networks. I tried to Forget it again, which works, but once I lock the phone and come back a few minutes later, that network is back in my list of networks under Managed Networks. The problem is that it keeps connecting to this network. I've tried rebooting the phone and that doesn't help. The really odd thing is that when I Forget the network from Manage Networks, it comes back complete with the password. The only work-around I have found is to leave the network in my Manage Network list and change the password to something incorrect so it cannot connect. However if I then Forget that network with the bad password, it comes back with the correct password. My question is - what can I do to permanently remove that WiFi network from my Manage Networks list (short of a hard reset of the phone)?
Thanks in advance for your help!
Lee

That's odd. All of my devices will forget a wifi network after I long press to get a dialog and choose "forget network".
Try forgetting the network when you are in a different location and not in range of that wifi network. Reboot the phone afterwards and see if the wifi network remains gone from the saved list.
Hope this helps.

Computer Won't See Wifi Networks

Hi,
So my laptop was working just fine until the day before yesterday. I didn't drop it, etc., but now it seems to be unable to see wireless networks.
Specifically, this morning I tried to connect it to a new network (I'm not at home) and at first it saw about 3 different networks (none of them in the house). Now, it doesn't recognize any networks at all. Is it possible that something is damaged on my wifi card?
My phone sees the network, which leads me to believe that maybe it is not a router channel problem, but something else. I have a 13 inch Macbook Pro from 2012 with Maverciks. Any ideas?
Thanks!!

Thanks for your quick response!
I have actually rebooted everything and my computer now sees SOME wifi networks, but still not the one that is literally half a foot away from me. The one that it does see, it can't connect to...
I ran the Diagnostics report, but that seems pretty useless...

4S iPhone will not discover WiFi network

My phone will not discover a WiFi network

Wow, same problem here after I upgraded to iOS6. My bluetooth and wifi both stopped working completely. I called tech support who told me i wasn't covered and acted like they had never heard of this happening and tried to sell me a $100 dollar warranty to get it fixed. I found these discussion forums and saw how many people were having the same problem and called tech support back to tell them I didn't appreciate the guy acting like he had never heard of this.
Turns out, I am completely covered under Apple care and she set me up with an appointment to get a new phone tomorrow, no charge. Now I see all these people who got replacements and are still having the same problem. Just when I thought I had everything fixed. Guess I'll just have to keep my fingers crossed.

Lumia 925 not discovering wifi networks

Hi community,
I am a Nokia 925 Lumia user. My phone, when switching on the wifi, begins searching for available networks, but remains stuck in searching mode. I cannot switch off the wifi slider once it is on and the phone never finds any networks. I am able to connect to the internet via mobile data however.
The phone connected to wifi once, but in the United States. I am currently in Trinidad.
So far I have tried both hard and soft resets as well as resetting to factory settings and nothing has worked. Is it possible that anyone has faced this problem and solved it? Please advise.
Thanks in advance,
Steph
Solved!
Go to Solution.

Hi Jimmy, thanks for your response.
The firmware version is 3051.40000.1347.0001 which I believe is the latest version.
There are no errors on screen, but as mentioned before, once the wifi is turned on I can no longer interact with the switch.
This happens with any wifi as I've tried at home and at my husband's workplace. The phone did connect to a friend's wifi in the States, but since I got it I have been having this issue.

Lenovo Yoga 11S won't stay asleep

I've recently purchased the 11S with the 4th gen Haswell CPU and I'm having trouble with putting it to sleep.
I've noticed that the laptop wakes up almost immediately after it goes to sleep whether I close the lid or explicitly select sleep in the shutdown options. This is after I updated to Windows 8.1, however I'm fairly sure this was also a problem before the update as well.
The only way it will properly sleep is if it is plugged in and charging.
I've tried:
Updating Graphics Drivers
Updating Intel DTPF Drivers
Installing Lenovo Energy Management program
I think this has to do with presentation mode because after searching around I found someone else who had the same behavior, but this was deemed to be a feature that's part of presentation mode. I would guess that it's stuck in presentation mode, however installing the Lenovo Transition program doesn't do anything. Also, I have no YMC.exe running which was said to be the Yoga Mode Controller.

Start Windows Event Viewer, go to Windows Logs, export the System logs as shown in the screenshot below.
Export it to *.txt or *.xml and upload it here for me to read. It might reveal the problem causing the Y11S to wake up.

MBP 10.5.8 won't see wifi network but iphone & ipad ok

not only that, but the pc's in the house runing xp, vist and 7 all see the network. i have access to the modem but am really reluctant to change anything for fear of disturbing everyone else's access. i've never encountered this with my macbook pro before - i've always seen networks. i can see many of the neighbours networks too. i have included a screenshot of the modem settings. i'd love some help! also, yes i am in Brazil and password is 10 characters [6 numbers and 4 letters]. Graham.

Hello,
I'm going to assume at this point that since the Modem/Router is set channel 13, that this might be an early 802.11a/b/g US MBP, North America and some Central and South American countries allow only 1 through 11.
Might try Channel 11 on it.

IMac 21.5-inch Won't Remember WIFI Networks

Hello. my not-even-1 old iMac 21.5 inch form may 2011 has another problem. It just started happening today. I turned on my iMac and started to use safari, when it said I wasn't connected to the internet. I looked up ath the top-right corner and none of the WiFI bars were filled. I put it back on my router and countinued on. I turned it off a little later, and came back and it did the same thing. I was starting to get concerned, so I reconnected and restated my iMac. It did it again. I read that repairning disc permissions is the best way to fix it. I tried it, but it did not work. Is my iMac broken? Also, it is using a 2.5 GHz Intel Core i5 and is running Mac OS X Version 10.7.4.

My troubleshooting goes:
1) reboot
2) go to activity monitor in utilities and see what processes are running, there may be a surprise there
3) look for the last several things I put on my computer to see if there is a conflict. I once downloaded something that had me going for hours, as the application downloaded shouldn't have messed things up, but it did.
Check that something like the memory isn't loose, go into "about my mac" and make sure everything checks out.
I have had iMacs for over ten years, and one thing I have learned is to trust my computer. All problems were software problems that I caused myself.
Well, if you have Applecare, they can usually spot the problem, though the process takes some time. But I am not an expert, just someone who has had iMacs for a long time.

HT1365 IPhone 4S suddenly won't join WiFi networks

Any ideas? At times, the on/off button in wifi settings is "ghosted".

See:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem.
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

WiFi features and Android Lollipop

Hi, A few weeks ago, I bought a Canon Camera. One of the main reasons for why I chose it was because you can connect the camera directly to any android device and copy your pics and videos. Unfortunately, this feature is still not compatible with any lollipop device. As a matter of fact, the firsts android L development preview were released on July 2014, i.e. 7 months ago. I've seen another post for this same issue (here), but there's only one reply from Canon on Dec 24. So I want you to please give us an official answer of what's going on with this and when is going to be released.
Thanks for your promptly solution.

First and foremost: this is a user forum, you're not going to get an official statement on anything here.
Second, what camera are you using, what app?
My Galaxy S5 hasn't been updated yet, but a look at the EOS Remote app says it supports 5.0 (Lolipop). I see from some of the comments that there's been some issues since the update, but that's par for course for any major software change. Regardless of the first Androids being released with 5.0, you can't expect third party manufacturers to stay current with state of the art, especially on this sort of thing. The general public with "old" devices - that is, ones not purchased in the last couple of months - are just now getting the update rolled out.
Lastly: again, I don't know what kind of camera you have, but my experience with the 6D is that RAW files are way, way, way too big to waste time with wireless transfer. I love WiFi for controlling my camera and seeing Live View, but when it comes to downloading I simply pull out my SD card and stick it in my computer. Just a thought.

Lenovo Yoga 2 13, Kali Linux 1.0.7, Ubuntu 14.04, Windows 8.1 install, config, and wifi fix.

Lenovo Yoga 2 13, Kali Linux 1.0.7, Ubuntu 14.04, Windows 8.1 install, config, and wifi fix.
I wanted to share an experience with everyone I hope will help others avoid what I have gone through the past 3 days. I bought a Yoga 11s that I loved but had some issues with the wireless, Lenovo being awesome replaced it with a Yoga 2 13. I love this laptop but ran into some issues with Linux install/wireless, which I wanted to show how to resolve in one place. Hopefully this will help someone else get through this quicker
I am going to try and write this for someone with little Linux experience, if I miss the mark please let me know and I will clarify the best I can.
For work I need Windows 8.1 and Kali Linux, while for home I prefer Ubuntu.
My Yoga 2 13:
I5 1.6 ghz
8 GB ram
256 GB SSD
ORANGE!
My requirements:
I need Windows
I need Kali Linux (livecd, even with persistent mode was not an option as it would not save the wireless fix or system updates) – I would also like this on a USB drive and not the internal SSD
I would like Ubuntu
Needed to do this:
1. 2 USB thumb drives (at least 8gb in size each) I used 2 Leef Supra 32GB drives. They are my favorite right now and are only about $27 at amazon.
2. Phone that can USB Tether or a USB Ethernet card (External USB wireless will show as "Hardware Locked"). Again you can pick one up for sub $10 if you need the USB Ethernet route. I used my Galaxy S5, you will need to download 200-300 mb of items through this so make sure you have the data if you go that route.
3. You may be able to get a USB wifi card to work if you do the following after boot. This only worked once for me.
                a.Type ‘sudo rmmod iwlmvm’
b.Type ‘sudo rmmod iwlwifi’
4. ISOs of Ubuntu and Kali Linux (I used Ubuntu 14.04 and Kali Linux 1.0.7)
5. Software to unzip the ISOs. I recommend 7-ZIP and will be referencing this in this guide.
6. I will include the EFI boot files and the WiFi fix files if I can attach. Otherwise I will provide a link to them.
   Link: https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
Recommended (these are just in case you corrupt something making your system not see any OS
1. I would call Lenovo beforehand and get a set of recover disks (this will take 2-3 days)
2. In the meantime a USB Windows 8.1 or 8 ISO (the repair feature may save you)
*Note: At many points in this guide I detail steps and commands. Please double check that you understand the step before proceeding. There are multiple points where a mistyped command or clicking the wrong option will cause your entire system to fail and you will need to reformat the entire drive and start over. This also will make One Touch recovery not work. Proceed with caution.*
I did not need to disable ‘secure boot’ to do this, but keep in mind that you may need to.
Steps:
First let’s go through the installs, and then we will go through grub config and wireless fix
1. In Windows scroll to computer and right click, select manage.
2. Go to “Disk Management”
3. Select the main HDD (notice Lenovo puts a stupid number of partitions on here)
a. I deleted the D: drive on here, if you do this make sure to copy the drives over to your main C: drive. You will want to run each of the installers and repair the drivers after.
4. I used the space from the D: drive and pulled a little more creating a 50 GB partition for Ubuntu and my swap file
a. You can also add more space by right clicking your C drive and selecting shrink
b. Do not format the partitioned data as this will make identifying it later much easier.
5. Open a command line
                a. Swipe from the right of the screen and select search
                b. Type ‘cmd’
                c. right click and select ‘run as admin’
6. For Ubuntu: Type ‘diskpart’ into the command line
                a. type ‘list disk’
i. You should see 2-3 disks depending on if you have one or both usb drives in the laptop at the time. I would suggest only doing 1 at a time so you don’t lose track.
                b. type ‘select disk $’ (Replace the $ with the number of the drive)
c. ***** Before proceeding make sure you have the correct drive selected or you can ruin your Windows install and Lenovo one touch recovery will not fix it since we have changed the partitions *****
d. type ‘clean’
e. type ‘create partition primary’
f. type ‘active’
g. type ‘format fs=fat32 quick’
h. type ‘assign’
i. type ‘exit’
6. For Kali Linux: Type ‘diskpart’ into the command line
                a. type ‘list disk’
i. You should see 2-3 disks depending on if you have one or both usb drives in the laptop at the time. I would suggest only doing 1 at a time so you don’t lose track.
                b. type ‘select disk $’ (Replace the $ with the number of the drive)
c. ***** Before proceeding make sure you have the correct drive selected or you can ruin your Windows install and Lenovo one touch recovery will not fix it since we have changed the partitions *****
d. type ‘clean’
e. type ‘create partition primary size= 3272
f. type ‘active’
g. type ‘format fs=fat32 quick’
h. type ‘assign’
i. type ‘exit’
j. By doing this we can maintain a portion of this drive as the install CD and still have linux install/ liveCD if we need to run it on another machine.
7. At this point the drive is ready to have the contents of the ISO copied over.
8. Right click the ISO and select 7-zip then ‘zip to /’ This should unzip the ISO to the location of the ISO into a folder named exactly the same as the ISO.
9. Once this is done for Ubuntu ISO it is done
10. Kali requires a little bit more to be ready
                a. Kali will need some files added for EFI boot. --$--
                               i. Thanks to: https://forums.kali.org/showthread.php?271-How-to-EFI-install-Kali-Linux
                               ii. EFI files are located within the wifi fix folder https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
11. Now let’s start with Ubuntu
Ubuntu install
1.     Place USB drive into the laptop and press the “Lenovo boot” button next to the power button
2.     Select ‘Boot Menu’
3.     Select ‘EFI USB Device (Name of drive)’ Mine stated Leef Supra
4.     Select ‘install Ubuntu’
5.     Go through the Ubuntu install until you get to select the install drive
6.     Once you get to the install portion it will ask you to select from one of 4 options. Select ‘Manually select partition’
7.     Select the “Free Space” where we opened up some of the drive
8.     You will need to create 2 partitions, I usually create the swap partition at the end of the drive
a.     First I create the swap
                                          i.    Set at the end of the drive
                                         ii.    Set size to 1024 mb
                                        iii.    Set type to ‘swap’
b.     Second create the ext 4 partition
                                          i.    Set to beginning of drive
                                         ii.    Set to remainder of the space
                                        iii.    Set type to ext4
                                        iv.    Set mount point to /
9.     Finish the install and boot into Ubuntu
10.   You will notice that your wireless is ‘disabled by hardware’ This is fine for the time being and we will worry about this after the kali install. If we fix it now for some reason after installing kali we get the error again and would just need to fix it again.
Kali Linux install
1.     Place USB drive into the laptop and press the “Lenovo boot” button next to the power button
2.     Select ‘Boot Menu’
3.     Select ‘EFI USB Device (Name of drive)’ Mine stated Leef Supra
4.     From the grub menu select ‘install kali linux’ both graphical and text work. I much prefer text install
5.     You will get a few errors through the install but that is fine
6.     The first we see is about network hardware and ‘load missing firmware from removable media?’ – Select ‘no’
7.     Then select no ethernet card
8.     It will have you name your machine then it will ask you for the root password
a.     If you want to just use root *not recommended* place the password here
b.     If you wish to use a non-root account then leave these blank and it will ask you for a name, username, and password of the new machine *Very Recommended* - this will also add this user to the sudoers file
9.     It will then ask you to ‘partition disks’
10.   Select manual
11.   Now here is where it can get a little confusing so read twice click once
12.   Select the USB drive from this list
13.   Mine shows up under (sdb) – Leef Supra
a.     It could be sdc, sdd, sde, etc… depending on how many drives you have plugged in.
14.   You should see one primary drive that is 3gb or so that is formatted as FAT32. – DO NOT TOUCH THIS PARTITION!
15.   You should see the remainder of this drive as ‘FREE SPACE’ select that
16.   Create a partition at the end at size 1024mb and swap
17.   Then create another one for the remainder of the drive and set it to ext4 with mountpoint of /
18.   Continue through the install after you should see an error warning you that ‘you may not be able to boot’ that is fine, select continue
19.   Then select from the menu of all the options ‘continue without bootloader’
20.   It should finish up then reboot on its own.

First setup/boot/fix grub
1.     You should be able to boot up into GRUB2 menu now.
2.     You may not see kali linux in this menu (make sure you have your towel and don’t panic!)
3.     Boot into Ubuntu
4.     Once you log in you should see that you still cannot use wireless due to being locked by hardware
5.     This is expected
6.     Let’s fix grub then we will come back to fixing wireless
7.     Plug in your device to connect to the internet (USB Tethering or USB Ethernet)
8.     Once you verify that you now have an internet connection run the following from terminal
a.     ‘sudo add-apt-repository ppa:danielrichter2007/grub-customizer’
b.     ‘sudo apt-get update’
c.     ‘sudo apt-get install grub-customizer’
9.     You can also edit the grub.cfg manually if you know what you are doing… I did not
10.   Open grub customizer
11.   It should auto populate and you should see ‘debian (kali linux)’ somewhere in the list
12.   It should be mounted to /dev/sdb2 or /dev/sdc2 depending on how many devices you have
13.   At this point go ahead and save
14.   Reboot and test that you can get into each OS
15.   This is where my inexperience got me. I spent 2 of my days so I am including this error: If when you boot into Kali you get an error somewhere that says ‘/bin/sh: can’t access tty: job control turned off’ look above it for an error that looks similar to ‘ALERT! /dev/sdc2 does not exist. Dropping to a shell!!’
a.     That error is due to the mount point being incorrect in grub, reboot and from within grub highlight the kali boot. Press ‘e’ then towards the bottom you should see ‘root=/dev/sdc2’ change this to ‘root=/dev/sdb2’ again the number doesn’t matter just make sure it stays the same.
b.     Press F10
c.     If this boots fine then you will need to go back and fix the grub.cfg or load into Ubuntu and open grub customizer again, it should fix this
16.   Now you have 3 working OS on the machine with one being on a USB! Congrats!
17.   You can remove the USB with no worry of screwing up your install, but you will not be able to boot into Kali Linux until you replace it. I would suggest only removing it and replacing it while the machine is powered off, but that’s just me.
Fix Wireless
Now is the time to do what probably ¾ of you came here for. FIX THE DANG WIRELESS. This is a huge problem from Lenovo’s side that I hope they realize how important Linux is and will fix. I won’t hold my breath though.
Log into Ubuntu : This is well documented in the following forum post on page 3 by user Haohe:
http://ubuntuforums.org/showthread.php?t=2215044&page=3
His has you download quite a large file, mine should be much smaller.
https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
1.     Download the attached package with the fix.
2.     Connect your USB internet device (tether or ethernet)
3.     Place the packages somewhere easy to access, in this example I will place them under ~/Desktop/WiFiFix
4.     Type ‘cd ~/Desktop/WiFiFix/’
5.     Now we need to prep the tools we need.
6.     Type ‘sudo apt-get update’ – we did this before, but you know, just in case
7.     Type ‘sudo apt-get install linux-headers-`uname –r`’   Note around uname-r they are the ` symbol not the ‘ this is located just above the tab on the same key as ~.
8.     Type ‘make’
9.     Type ‘sudo cp /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/ideapad-laptop.ko ~/ideapad-laptop.ko.backup’
10.   Type ‘sudo cp ~/Desktop/WiFiFix/ideapad-laptop.ko /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/’
11.   Type ‘sudo modprobe -r ideapad-laptop’
12.   Type ‘sudo modprobe ideapad-laptop’
13.   Type ‘sudo rfkill unblock all’
14.   Type ‘sudo modprobe -r ideapad-laptop’
15.   Type ‘sudo mv ~/ideapad-laptop.ko.backup /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/ideapad-laptop.ko’
16.   Next we need to blacklist the ideapad module
17.   Type ‘sudo echo 'blacklist ideapad-laptop' > /etc/modprobe.d/blacklist-ideapad.conf’
a.     The first time I tried this it wouldn’t work. So I did the following
b.     ‘sudo touch /etc/modprobe.d/blacklist-ideapad.conf’
c.     ‘sudo vim /etc/modprobe.d/blacklist-ideapad.conf’
d.     Enter     blacklist ideapad-laptop
e.     Exit and save
18.   Reboot your Yoga 2 13
19.   Boot into kali and see if you have wireless, if you do then you are done. If not we will need to repeat this process with one small little change.

Lenovo Yoga 13 WIFI Problem - making sense of the problem

Hi Lenovo
For the past 3 days i have been doing some research and observations in order to try to make sense of this wifi issue and maybe someone will come up with a solution.
Lets start
First of all i assume that when this laptop was being developed some form of testing was done before it was released, so the wifi must have worked well within lenovo offices.
Also not everyone is having this issue - some people claim no problems at all, whilst others whathever they try they can't seem to be able to fix it. Some even send their laptop for repair, other even had it replaced, yet the problem still persisted.
So the problem seems to be related to one factor - the router people are using.
Some people have a router that works well with this laptop, and so have no issue.
Other have a router that is "not compatible" with the wifi card and so no matter how many lenovo yoga 13 machines they have it will still not work.
I also noticed in my situation that when i use my android phone or tablet as wifi hotspot i have no issues, yet when i use my home router its a nightmare.
Also i noticed that chaging the way how the laptop connects to the router can make a difference;
1, At first i used a fixed IP with alternate configuration - this was horrible (continous disconnection, routers wifi crashing, takes ages to connect)
2, Then i used fixed ip in the general configuration - ths was better, yet still problems (yet disconnections were less, yet still took long to connect and at times router's wifi crashed)
3, Dynamic Ip - this is the best configuration - connects quickly, does not disconnect, yet internet connection slow and at times routers wifi crashes.
So i think its a question of compatablity with the wifi network you are using.
Also based on this i do not think this is a hardware issue - since hardware problems tend to be all or nothing - whilst in this case if one connects to a "compatable" router the connection is good.
So this is a driver issue and thus if lenovo puts some effort in this - it can be fixed - yet this doesn't seem to be the case unfortunately.
What can help from our side if everyone posts the routers and connection settings (e.g. static ip, dynamic ip etc) they are using and stating whether their wifi is working or not.
Maybe we can close down on the problem and find a fix asap.
Let me start with my configuration.
Samsung galaxy s2 and samsung note 10.1 - wifi tetharing - works fine
Belkin Pre-N router with dynamic ip and wpa2 password - problems

Solved!
Go to Solution.

I had the same problem. I came across someon that found a fix. My Yoga is restoring right now (I tried windows 8.1, it didnt work outwell) so I can't tell you the exact steps but it goes something like this.
1.) right click my computer
2.) click properties
3.) Device Manager
4.) open properties of WiFi device (under network adapter)
5.) Go to Advance
6.) there is an option to use use either 20_40w or 20w under one of the energy/power related options in this list.
(This is part I can't remember off the top of my head) - Turn to 20w instead of the variable rate.
6.) Change the Bandwith option from 20_40w to 20w.
5.) OK out till your at your desktop (might require Reboot, I dont remember)
That is how I kept my WiFi from destroying my Wireless networking in my house. I was rebooting my WiFi network hourly before.
