Other wireless networks cause failure?

Has anyone encountered an issue where another wireless network in the area has induced your Extreme to fail to obtain anything but a 169.x.x.x address?
I was thinking there was something wrong with our Airport; I even took it to the Apple store where it immediately connected. We've not been using it at all for the past month or two. Last night, we had a power outage on our block except our house (different grid apparently) so on a whim I'd plugged the sucker in. Damned if it didn't connect right away and sing.
Today, all lights and competing neighborhood networks are back on, and no connecting via Airport. The Airport is on, all lights operating and seemingly connected. However, I cannot get a valid IP.
Anyone else had this problem? If so, what did you do about it? We are using WEP incryption and a closed network.
Thanks and happy holidays!

Sounds like that you may have some form of WiFi interference in the area.
I suggest you perform a simple site survey, using utilities like AirPort Client Monitor (a part of AirPort Management Tools), MacStumbler, or iStumbler to determine potential areas of interference...and either, eliminate them or attempt to significantly reduce them.
Some of the things you can do to improve your WiFi reception...
- Try switching channels until you get the best performance of your Wi-Fi network. Most others will be using their router's default, which are channels 6 or 11. From your site survey, you should find the channels used by your neighbors, especially the ones with the strongest signal. Try to use a channel at least three channels away from them.
- Turn on "Interference Robustness" on BOTH the AEBS AND your Macs.
To enable Interference Robustness on the AirPort card:
- From the AirPort icon on the menubar, click to select (enable) "Use Interference Robustness."

I have an old iphone 3G that I want to use as an ipod touch. It does have a sim card and it has been reset but for some reason it will not pick up my wireless network, or any other wireless network. What is the problem?

I have an old iphone 3G that I want to use as an ipod touch. It does have a sim card in it and it has been reset. For some reason it will not pick up my wireless network in my house, or any other wireless network. What could be the problem?

Is this the problem:
iOS: Wi-Fi or Bluetooth settings grayed out or dim

2nd MBP can see all other wireless networks except TC: 1st sees TC fine?

This is totally mystifying: I have an older generation MBP running Leopard, and it can see the Time Capsule in Airport Utility and in Networks, connect to it, backup to it, and access the internet no problem.
I also have a newer model MBP running 10.5.8. This one can see every other wireless network in our building except the Time Capsule. Can't see it in Airport Utility either (latest version).
Haven't found any solution to this anywhere. Help me guys, you're my last hope!

I can now tell you all this is the well-known HARDWARE fault whereby the wireless antenna screw comes loose.
Have done this back up and it is now 100%.

Problems reading other wireless network.

Hello everyone,
I am writing this message because in the last weeks I have been having a problem with my wireless network on my macbook. Every time that I open the computer it reads another network first and not the one that is mine. My other computer, ipad and ipod touch are reading the network that I own, but this macbook is not reading it first. I always have to go to network settings and changes it.
Any advice or help in that regard? I will appreciate it.
Thank you.

How to use ethernet connections on a TC that joined other wireless network?

My TC is setup to join a Linksys wireless network and works fine as network drive and backup utility for Time Machine.
I have a HP all in one printer connected to the TC by ethernet cable but that printer is not getting an IP address. When I connect the ethernet cable to the Linksys router (in another room) it gets the IP address right away.
Is it possible at all to connect the printer by ethernet cable to a TC that joins another wireless network?
If so what do I need to change?
Thanks,
Menno

On the Mac that the printer is plugged into, go to System Preferences/Sharing and turn on Printer Sharing.
The rest of the Macs can now use the shared printer as long as that Mac is turned on...

Why is my laptop only connecting to the base station at home and not other wireless networks?

I can't connect to public wireless networks. I connect to my work wireless through 802.1X connection, but in other places my wifi just looks for the base station, and doesn't pickup available public guest networks. Any assistance is appreciated!

Take all the applicable steps in this support article.
Step 2
If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it.
Step 4
This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.

Internet from time capsule 1/5th the speed of other wireless network

Hi...
Here's the problem. I have a time capsule 500gb set up in my house and connected via ethernet to another linksys wireless router and then via ethernet to my ASDL Modem. The problem i have is that the internet connection (when tested on Speedtest.net) is aprox. 1/5th the speed of the linksys network. any idea's why that might be?
I have my time capsule set up in WDS mode with an 802.11g Airport Express to distribute the network through the entire house. The speed is the same if i'm next to the time capsule or in any part of the house so i don't think its a signal strength thing. Any suggestions?
Thanks in advance

No, you are not using a full IPv6 system.. you are simply making sure the link to the TC is able to use IPv6.
Go to the Networking preferences and bring up the wireless setup, advanced. TCP/IP
Change the IPv6 setting to link-local.
Ensure ipv6 is set in the TC to link-local.
So click on the TC in the airport utility.. click on edit.. click on the internet tab. Click on internet options.
Then test your speed again.
If you have issues still give us a link speed when you are sitting in the same room as the TC.

TS3899 When at home using our home wireless I can send and receive emails on my iPad no problem. When using other wireless networks I can send emails to people who share the same Internet provider but not others. Why?

Is the wireless provider the issue? I can receive emails everywhere I go but in some locations can only send to a limited number of email addresses.

Greetings
I suspect that the issue is the SMTP server settings. On your home network you are using your providers SMTP server and all is fine (If you check your email account configs you will find that the SMTP server is set to your providers?).
When you use a different network (provider) mail will not be sent unless you use that networks (providers) SMTP server (this is a security issue to address ways of "spamming").
So if youre 3G/4G provider is the same as you home provider all will work well via your home WiFi. If you turn off WiFi and just use your 3G/4G connection to send mail (iPhone/iPad etc) all will work well (when you are out and about and using anothers WiFi network).
If you are connected to, say a MacDonalds WiFi, mail will probably not be sent. (It will be received though).
Using WEB mail interface (via your WEB browser) removes this problem as well.
(A SMTP server is what is used to send email. So to successfully use anothers (not a networks the same as your providers) WiFi network and send email via it, you must know the SMTP servers name and reconfigure your email account/s to use that server to send mail.)

Other wireless networking interfering

Hello Support Community
I have an Apple Airport Express, several years old which replaced my Apple Airport (dome style) unit. At that time and even today I am knocked off by neighbors even though our houses are hundreds of feet apart.
I've researched this extensively over the years, changing my channel from automatic to certain fixed channels. I'm at my breaking point from having to walk down into my basement where m Comcast router is and my Airport Express is located and shutting the power down and then turning it back on.
Interestingly enough, it's only a problem at key times of the day such as breakfast and dinner. Whenever I lose Internet I see the neighbor's as on.
Will buying the Airport Extreme solve my problems?
Thank you.

Hello edex67
I am in the US and when I have stumbler open I notice that I'm on an Express that only goes up to 802.11g whereas my neighbors are on 802.11n. Now I'm seeeing another neighbor who I don't see that often. The name of his router is the 1st haf of his Mac Address.
Your suggestions make sense about updating to a new router that has the n capability and one with greater range. Moving my router would involve drilling some holes up through my basement ceiling to the floor above going through a finished ceiling (which I'd rather avoid) so keeping it in place and getting a stronger router appeals to me.
I'm wondering if luneiri cna give me any more insite on using Stumbler.
Thanks again.

PCs suddenly no longer see Airport Express wireless network - please help!

Hi,
I am new to this forum and I need help. Two days ago - without me making any changes to settings etc. my Airport Express wireless network at home was no longer visible to any of my devices except to the Powerbook (G4 OS 10.3.9) which controls it. From one second to the next two Vista laptops and my cell phone (Nokia, Symbian OS).
My Powerbook has no problem connecting through AE to the internet. The two laptops are both able to connect to other wireless networks so they don't seem to be the problem. I just don't understand what caused this sudden drop-off/invisibility.
I have already tried the following: resetting the base station, changing the channel on the base station (from automatic) removing the network security altogether (from WPA2). But none of the devices except the powerbook can now see or detect my network.
Please - if anyone knows what the cause of this problem could be or how to fix I would be very grateful!!

you name it : com.apple.airport.adminutility.plist
delete it and do as advised.
This isn't harmful, because it is only a preference list, so it will be created brandnew as soon as you re-setup the Airport stuff.
Mac OS X ( especially Jaguar ) has a tendency to corrupt some plists out of the blue, it is more or less harmless and can be fixed with recreating them plus permissions-repair.
Hint : repair permissions more than one time, it ALWAYS finds something to fix in Jaguar.
You cannot destroy something with these actions, because it is Unix maintance so usual routines.
A tool like cocktail or Onyx ( google them, onyx is freeware ) can help you run such ( and more ) routines on a scheduled base.
Always remember that OS X is no longer "the Mac OS", it is Unix with a nice Desktop, the critical things run hidden in the background, so it has to be treated like any Unix/Linux sort of OS, even if from the outside everything looks nice and kosher..

Which is the best channel to use - on overcrowded wireless network ?

Hi,
I've had my Airport Express network going for just over a year with no problems, until the last month when my neighbours have all got Broadband for Christmas and now my network is very unstable and I cannot play more than 2 minutes of music until the network disconnects - I have not changed anything in months because "it just worked."
I found a nifty utility for my iMac which shows other wireless networks and the strength of the signal.
Three other networks show up, on channels 1 or 11 they all have stonger signals than me even though they are 10 Meters away through brick walls (my closest neighbours do not have wireless, so I am assuming it must be at least two houses away in either direction.)
I have changed my network to run on channel 7 and iTunes now streams properly without regular drop-outs.
Now, I am wondering, my network is set-up as "hidden" and does not show up in the network scanning utility, so logically some of my neighbours may also have "hidden" networks - how can I tell if any of them are using the same channel as me ?
Anyone got any ideas or advice ?
Thanks

I use the 'iStumbler Spectrum widget', which shows me how much congestion there is. After identifying where the most congestion is, its simply a matter of identifying which of the channels without much congestion works best for you. There isn't really a magic formula, though trying different settings until you have a better signal to noise ratio is all I can suggest.
Also, remember that 2.4GHz phones can also cause increased noise.

Lost Connection to C&C Generals Zero Hour Online using the WRT54G v5 Wireless Network

I have this problem playing Command & Conquer Generals Zero Hour online. I'm using the WRT54G v5 Wireless Network & when I'm in the game lobby, it kicks me off saying, "Lost connection to C&C Generals Zero Hour Online". This happens quite often variing on me entering & exiting rooms or other players entering & exiting rooms that I'm in. But it doesn't occur when I'm accually play a game with someone. It also does not happen at all when I'm connected directly to the internet connection so I know the network is causing it.
I've never had any problem with this game on any other wireless network types before. I've tried port forwarding with a static IP address, disabling firewalls, upgrading firmware, etc... No good. I've done some google research & found that varios other people on other forum sites have the same problem, it also occurs on another computer of mine.
Is there some kind of feature on this network that isn't on any others? One wireless network specificly that I've found that the game works on is the WRT54GS.
Any replies will be greatly appriecitated.
Message Edited by Me Myself AndPi on 02-20-2008 03:13 PM

Maybe I would if I hadn't stopped playing the game 3.5 years ago. You may want to check the date on those previous message. But here's what I remember:
Turns out nothing worked the fix the problem. Not turning of a firewall, not port forwarding, not updating fireware, nothing. There must be a jitter on the routher that triggers the game into thinking it gets disconnected.
Many other users on the forums posted the same problem with this one router too & no one ever figured out a solution. Eventually that router broke & my family bought the WRT54GS2, which worked perfectly.

Adding 802.1x Wireless networks with a script

Hi,
We have some new wireless networks we've set up for students to use (I work in a University). The networks use 802.1x authentication, and WPA2-Enterprise encryption. Adding Macs with various versions of OSX isn't a big issue, but it's time-consuming. Users need to follow an instruction sheet, and the process is prone to errors.
I'm looking for a method to give users some sort of download to run, which can just add the SSID for our wireless LAN with the minimum of fuss. I've dug around and found various things, but I'm a little perplexed as to how best to go around it. I've seen things suggesting an AppleScript would be able to do it, but I'm no AppleScript export, so some sort of example would be nice.
Any pointers gratefully received.

did you find any resolution to this? our mba- mid 2013 deployment is having a very similar problem. We've gone through loads of troubleshooting and have yet to come to a resolution. all our mid 2012 mba's are working fine they're 10.7.5/10.8.4 mixed. console logs don't show much, i'll try the wireless diags tomorrow. our other 10.8.4 build appears fine on other models of machines. i've read posts about deleteing the adapters, deleting the system config plists and changing the mtu size, these steps do not work for us.
we don't have as high a failure rate with our deployment, but 25%-30% of our clients randomly drop connectivity and are unable to reconnect (fluttering wi-fi wave). when you slect the wifi symbol in the menu bar other wireless networks do not show, the 'looking for networks' fly wheel continues to spin. ocasionaly on login the yellow jelly bean will appear then disappear before finally timeing out without logging the user in (depsite having mobile accounts enabled). mostly the problem manifests itself when waking from sleep - the wifi symbol flutters endlessly without connecting. deleting the 8021x profile and readding it will reenable connectivity. we've tried new profiels, but to the same end. i know our certs and systems are fine because previous mac os x builds work fine as do our windows clients.
any input would be much appreciated.

All wireless networks disappears time to time

sometimes the macbook cannot fined any wireless networks even not mine, at the same plase you have had connected with the same MB PRO. The problem is not with the router cause it cannot finde any other wireless networks which i'm pretty much sure that there is in the building. At some points when i restart the MB PRO the problem is gone and sometimes it is still there. As of this posting the MB PRO cannot find any wireless network but the IPAD is just fine.

I have the same problem with my laptop.
Allow computer to turn off device to save power: is not checked.
Advanced power options: the Wireless Adapter is set to "Maximum Performance".
I have a static ip set to 192.168.1.2
It was working for months then stopped 2 months ago after I had troubles connecting to a friend's wireless network unsuccessfuly. So I believe I must have changed something, but what? I have even removed the wireless adapter and re-added with
latest drivers.
I have 2 laptops on the wireless LAN. One is connected immediately when I open the lid after sleep, i.e. wireless adaptor enabled & I can browse and work online. The other has to enable the wireless adapter and re-connect to the router
which takes a minute or so. Not a showstopper because I am then up and running... but very frustrating.
I have trawled forums and searched for 2 months now. Could very well have missed the solution somewhere?
Good luck milky9311, I hope we both find the solution here. Thanks in advance for any suggestions.

Need help here! I'm out of options. Computer can't see the wireless network

Sorry for the novel, but I have to tell you what is going on with my computer. I also need to vent because I’m extremely frustrated. I want to make sure I give as much info as I can we can get this fixed. I’m done with trying to figure this out on my own!!!
I’m having a major issue with the wireless network connection on my desktop. I’ve tried everything and I can’t figure out what it’s doing.
First of all, my wireless router is set up correctly (according to the Sticky), has active security, and works fine. It has nothing to do with the router. I’m sure of it.
Here’s a quick history:
When I was at my first residence in Chicago and bought a Linksys wireless N router in May 2008. My computer was about 30 feet away from the router and everything worked fine. Always found the router and never lost connection.
I moved to a new place in September 2008 and used the same router, computer, etc. at my new place. The computer was only about 7 feet away from the router this time, but I used the wireless connection instead so I wouldn’t have a network cable lying across the floor. At first everything worked fine. No issues. Then, one day out of the blue, my desktop lost connection with the router. My router didn’t even appear as an Available Wireless Network. I rebooted everything and that seemed to fix it. OK, issue fixed, right? Wrong. It did it again the next day. I rebooted everything, but it still couldn’t find my router. It did see lots of other wireless routers in the area though so I know the wireless card was working. It just didn’t see my router.
This went on for a while. Sometimes it would see my router and connect then it would lose it again. I thought maybe it was the router going bad. Well, I have a notebook computer too so I tried it. It has found my router every time and has never lost connection. I had it sitting on top of my desktop even to see if there was some sort of dead spot in my condo, but the notebook found my router just fine.
Sometimes my desktop would see my router, but it wouldn’t be my network name. It would call it “Home” or something. I know it was my network because it was the only network with maximum (Excellent) signal strength. I’m thinking it must be some sort of association issue. For some reason it doesn’t associate my router as an available network. I don’t understand that.
I tried everything: Ad Aware, Live OneCare, registry cleaners, driver updates, restore points, pretty much anything I found in the forums. Nothing worked for long if at all. It’s like my desktop only finds my router when it wants to. Note: The only thing that would work sometimes was if I clicked “Repair.” Sometimes that would work. I finally gave up and connected my desktop via network cable and unhooked my wireless card. I never lost connection as long as it was hard-wired.
The drama continues. I recently moved to Iowa and set up my network here. I’m using the same router, same desktop and wireless card, same notebook computer, etc. I went ahead and tried the wireless card on my desktop again. It worked just fine! No connection issues at all. It connected and stayed connected. I thought, “Well, that’s strange. It must have been something with the condo in Chicago. Oh well!” It worked fine from February 5 until March 10. Now it’s doing it again!!!! The notebook is about 3 feet away and sees the router just fine.
Here are the facts:
I’m using a Linksys WRT300N Wireless-N router.
I’m using a Linksys Wireless-N PCI WMP300N Adapter (about 18 months old).
I’m running Windows XP on the custom built desktop and Windows Vista on the HP notebook.
I built this computer about 5 years ago and have not done any major upgrades for 2-3 years. The only thing I added was the wireless card. I also changed out the HD in January 2009 and did a data migration right before I moved to Iowa in February. All of the networking issues were going on well before I did the data migration though so it has nothing to do with that. In fact, I had my computer hard-wired into my router at the time of the data migration and the wireless worked fine (for a little while) after I moved to Iowa. So if anything, the data migration seemed to help with my wireless connection.
All drivers are up to date.
Using Windows Live OneCare and have run complete scan: nothing found.
Using Ad Aware and have run complete scan: only found cookies and deleted them but didn’t fix issue.
Ran WinsockxpFix but that didn’t help.
Ran TweakNow RegCleaner Standard but that didn’t help.
Right-clicking the wireless icon, I try to view Available Wireless Networks. The window comes up and shows me other wireless networks in the area (2 available right now), but doesn’t show my network at all. I click “Refresh network list” and 1 or 2 of the other networks will come up, but mine is still not shown.
I’ve clicked “Repair” and get this message: “Windows could not finish repairing the problem because the following action cannot be completed: Connecting to the wireless network.”
If I go to Control Panel, there is a Wireless Configuration Utility program from Broadcom. When I open that here is what I find:
It is not managing my wireless networks.
Under the “Wireless Networks” tab I see my Network with an “X” over the router icon to the left of it and a locked security icon to the right of it.
No information under the “Link Status” or “Statistics” tabs.
The “Site Monitor” tab shows my wireless network and the other 2 networks in the area (although they drop in and out because of signal strength). My network is always present even though the signal strength bounces up and down. This tab shows that my network is secure, 802.11 is g and n, speed is 270 mbps, Channel is 9, and Signal bounces from orange/red to green. Data encryption is (m)TKIP, TKIP, WPA-PSK.
I was going to use my notebook to post this message since it has been connected for 2 days without ever losing connection. It shows Very Good signal strength and is about 3 feet away from my desktop.
Update: My desktop just connected to my network after sitting there for 2 hours. Good to Very Good signal. Broadcom tool shows the connection and now has information in the Link Status and Statistics tabs.
Cancel that. It just lost connection again. It was only connected for about 5 minutes. There is no change in signal strength according to Broadcom though. In fact, Broadcom shows better signal now that I lost connection.
Now, it just connected again (on its own) after sitting there for 10 minutes! I’ve been surfing the web on my desktop for 45 minutes now and I’m using my desktop to post this message. What the heck?!!! This is what it’s like. Aggravating huh?
Well, that’s all I can think to write. What else do you need? Can anybody help me with this?
I’m confused. Please help!
Thanks a lot!!!
Jake

Thanks but it's just my desktop that doesn't see it though. My notebook sees it everytime, even at the same exact time that my desktop doesn't see it. For example yesterday when I was typing up this post, I was typing up the post on my notebook because my desktop didn't see the router. I don't think it has anything to do with the router actually, but I wanted to see if anyone on here has encountered this issue before. Other forums have similar issues but I've tried all of the fixes I found elsewhere and they didn't work.
Any other ideas?
Thanks!
