Wireless network drops

Hey all,
I bought a MacBook exactly a week ago, so for I love it. during my decision process I was leaning towards the MacBook Pro but I could not justify the $2,000+ price tag. But I am happy with my decision in favor of portability ()as a college student).
Now to my problem, when I boot into OS X my preferred network connection is lost. The AirPort card sees my preferred network but when I go to input my WEP key I receive an invalid password message. Other times when I boot into OS X I receive no message that my preferred network is unavailable. Is this a known issue in the firmware?

Hello, Artotture
and welcome to the Forum here. I'm convinced you won't be deceived by your Macbook, its a very good little machine!
Connection with WLans can be tricky, but once you solved it it keeps working!
It is not clear to me from your post, what kind of network you are talking about. Is it your private one at home, based on an extreme" or similar? or is it a WLan in your school? The approach would be different in the 2 cases.
If it is your own home network, you should give more details about the base station. In case of an "Apple airport express" it helped (was needed) in my case that i reconfigure the network base station, and that i use a new name.
In case of the network at school, you should make sure that you have the correct "security" settings. When choosing a network which you want to join, there is a "security" pull-down menu, with about 8 different security protocols. You must - of course - click the right one for the WLAN which you want to join.
Hope this helps

When I switch my time capsule to 5.0ghz mode the range of my wireless network drops significantly. Near the Time Capsule my Macbook Pro works fine, in my bedroom I have almost no signal. In mixed mode it works fine. Any ideas on how to get 5.0 working?

In mixed mode it works fine both placed. Any ideas on how to get 5.0 working? I thought 5.0Ghz was supposed to have a wider range. Do I need to change a setting on the Macbook Pro?
Thanks, W

I'm not sure if you understand that 5 GHz has some upsides, but also some very significant downsides.
The upside is that the 5 GHz signal will allow faster speeds.
The downside is that you must always give up something in order to gain something else.Unfortunately, the marketing hype about 5 GHz does not go into very many details about this.
In the case of 5 GHz, the 5 GHz signals are much weaker than 2.4 GHz signals, so they do not travel as far or penetrate any obstructions like walls or ceilings nearly as well as 2.4 GHz signals. In many cases, in order to get good 5 Ghz performance, you literally have to have almost a line-of-sight relationship between your computer and the wireless router.
If you have a new dual band router, which broadcasts both a 2.4 GHz and 5 GHz signal simutaneously, your Mac will connect to the best signal quality automatically depending on its location in relation to the router. In the same room, without any obstructions, it will connec to 5 GHz. But, take the laptop down the hall a few rooms and around the corner and the Mac will connect to the 2.4 GHz signal because at that location, the 2.4 GHz signal is not only stronger, it is also faster.

Wireless network drops every 5 mins

hi there,
We have a cisco 2500 wlc and (software version 7.0.220.0) and 4 access points (AIR-LAP1131AG-E-K9).
The wireless network is virtually unusable as people keep getting kicked out every 5 mins.
I've attached the trap logs. Hopefully someone more knowledgable than I can take a look? One entry I've noticed is....
Warning: Our AP with Base Radio MAC 00:3a:XX:7c:22:f0 is under attack (contained) by another AP on radio type 802.11b/g
Can anyone offer some advise on this?
Thanks in advance.
-Al

means your user have to relogin or what after 5 minutes.
Check your user idle time out and make it to 86400.(controller > General)
also check your seassion timeout, make it to 65535 (wlan > edit then go to advanced)
Then try agagin.
Hope it helps.

Wireless network drops out on one MBP, not the other

I have two Macbook Pros as part of a wireless network (Extreme/Express 802.11g). Lately the older of the MBPs (2.16 Core Duo) keeps losing the connection and won't recognize the network. If I restart the Airport Extreme and my modem and the MBP it will sometimes come back. Meanwhile my brand new MBP never loses the connection.
Anybody have any suggestions on where I can start looking or what I can start adjusting to eliminate this problem? Please don't hesitate to let me know if there's other info I can provide to help solve this.
Thanks in advance.

If you place the two MBPs side by side for a few hours, does the older device still lose the wireless signal while newer one remains connected?
If yes, then you may have a wireless card that is starting to act up or the internal antenna connector may be making intermittent contact. A repair shop will need to check things out.
If no, then you're likely picking up some form of wireless interference in the area where the older MBP is normally located. The usual culprits are a cordless phone (sometimes at the neighbors) and nearby wireless networks. Post back for a few suggestions on this.

Dual Band (5ghz and 2.4 ghz) Wireless Network Config and Dropped Connection

Hi, I have an Airport Extreme (802.11N) and a Motorola WR850G (802.11A/B/G) that I'm trying to connect in a dual band setup - but something in my setup is causing the Airport to drop it's connection (before the connection is dropped - everything works great). After I lose connectivity, both routers show up in my list of wireless networks, the light stays green, but I don't have local or internet access. When I try to reconnect, the log on times out. Also, the Airport isn't displayed in the Airport Utility (light is green on the airport itself though). Unplugging and resetting the Airport Allows all computers on the network to connect locally and to the internet for a few hours until the connection drops again. While it is up and running, I have no problems streaming movies off the connected Airdisk, navigating the internet, and connecting both N and G devices to the network.
I'd love to hear from you if you've gotten a similar setup to work, and if possible, have you provide the settings you used to make this work. I've looked around quite a bit and haven't seen a detailed description of the process (even from the Apple documentation). Also, advice from anyone would be greatly appreciated since my wireless networking knowledge is pretty basic.
My configuration:
Time Warner cable modem connected to the Airport's WAN port. WR850G connected by LAN port to Airport's LAN port. Bridge Mode check box selected on WR850G. Airport setup for 802.11n (5Ghz). Unique SSIDs to determine which network is 'N'. Same password for both networks. My Firmware and utilities are up to date.
Computers/Devices on Network:
Two Macs with Airport Extreme N cards. A Vista PC with a D-link N card (only compatible with 2.4 Ghz so it connects to the G network). A Vista PC with a GB ethernet card connected to the Airport Extreme. Various other G devices like iPod touches and an old iBook. Airdisk connected to the Airport Extreme.
Thanks,

I removed the second router (Moto wr850g) and everything seems to be working smoothly. It must be some settings on that one that are causing the problem, but I haven't been able to get it configured correctly. I noticed there were some IP conflicts with my wireless wanting to use the old Moto router IP and trying to assign my Mac an IP from that router. Does anyone know specifically what needs to be disabled on a router in bridge mode? Since I have a third party router there aren't any handy wizards that can configure it for me.
Thanks again

Wireless connection drops on 1/2 of computers on network

I have an Apple Airport Extreme N Router setup to feed my NAS wirelessly to all computers on my network. Some computers on the network can sign in wirelessly (Via TP-Link TEWDN3200 USB Adaptor) and connect to the NAS. The other half drop connections all the time and cannot connect to the NAS in any way using the TP-Link USB adaptor or the PCI-e adaptor. (Via Webserver or mapped network drives) Computers which are wired directly to the router can access the NAS without any problems.
Some more facts:
- All computers (with and without the problem) are running Windows XP PRO 32 bit SP3
- Some computers are using a TP-Link TL-WDN4800 with latest drivers
- All computers are connecting via the Wireless Zero-config service
- In the 'status' window on the wireless network, for computers that connect fine, the Netnwork ID remains solid and the connection looks stable.
- In the 'status' window on the wireless network, for computers that can't connect, the Network ID flashes in and out and the network speed bounces between 450.0 Mbps and 200.0 Mbps. Said computers eventually lose connection and then automatically reconnect only to drop out within an hour or so.
- All PC's are using DHCP and the addressable range is 99 on the NAS. More than enough for 7 computers.
- All computers are in the same room and the problem is evident no matter which broadcast channel I use or which frequency. (2.4 gHz or 5 gHz) It is now set to automatic in the Airport because it seems the most stable.
- I installed a WDN4800 PCI-e adaptor into one of the PC's that worked with a USB adaptor and it no longer works with either!
Very frustrating!
I did some troubleshooting with TP-link, thinking it was their card, but came up with nothing. They think it's the Airport.
The only telltale sign that the PC is not going to work is that Network name in the status window of the wireless connection. If it's flashing: It won't connect. If it's solid: it works flawlessly for weeks on end.
Has anyone seen this issue before? If so: what did you do to fix it?

SOLVED:
The Airport Extreme is dying. Why it works on some computers and not others is beyond me but, after replacing it, everything works flawlessly. I hope this is covered under warranty.

Wireless network connection drops on my Tecra A4

Hi,
When I am downloading a file ( or just only connected to the web), the connection drops about every 30 seconds for a few seconds. I have tried a lot things, like changing the channel, changing the security setting (wpa/wep), tried another places in the house, but if I sit only a meter from the router, I have the same problem.
The strange thing is the the computer that is directly connected by cable to the router does not show any problems at all..
also see http://www.sappa.nl/dumeter.jpg for an illustration of my problem.
I have read about a possible solution (http://arstechnica.com/news/posts/1080251780.html) by turning off the windows net zero service, and instead of this service to use a different program to search and connect to your network (configfree?!)
I am using a netgear WPN824 router
My laptop is a Tecra A4
Greetings!

Hi
Its not easy to give you a proper answer.
If your unit works with the Atheros WLan card you should use the Atheros Client Utility to configure the WLan settings and the option Use Windows to configure my wireless in the Wireless network properties should be disabled.
Furthermore please check the Toshiba website for new Wlan driver. Maybe the new update could solve the problem.
Bye

IPADs and IPhones dropping off wireless network

I have a site with a number of iphones and ipads that are attaching to a Wireless network managed by a lan controller ( cisco 2504 )
but they seem to drop off every 16 minutes .... and can then get back on a few minutes later.
Any ideas appreciated.
Thanks

Right now I have it in the setting; "(OFF) Bridge mode". Do you know if the airport extreme if the internet bottle necks will crash?

Apple Devices Dropping Off Wireless Network

Hello, I have recently deployed a wireless network using a WLC 2504 with 21 Light APs. All seems fine except that
Apple Devices drop their connections every 15 minutes or so. A couple of minutes later they can reconnect but
obviously something is wrong.
Many Thanks

Only Apple device exhibit this kind of behaviour?
What kind of Apple devices? Mac laptops? iPad, iTouch, iPhone?
Have you seen this behaviour from, say, non-Apple devices? Android? Windows laptops?
What are the signal strengths when this happens?
Do you have Aironet IE enabled?
How far are the clients from the WAP(s)?

My C7280 keeps dropping the wireless network but my C7180 is okay

My C7280 keeps dropping the wireless network but my C7180 is okay both have set IP addresses, both in same room and the C7280 has to be setet to see the wireless. It will work okay all day but the next day it has dropped the network.
Any ideas

What operating system? There is an update for "Windows 7 Critical Update to enhance reliability of network connection", the version for 64 bit Windows 7 is here. If you have a different operating system check HP's download page for your appropriate operating system and look for updates.

Dropped Wireless Network

I have a new MacBook Pro. I have configured it to connect to my home wireless network and set that network as the preferred network.
Every so often, can be as frequent as every few minutes, my MacBook Pro will drop my preferred network and connect to nothing else. I just lose all network connection. Re-selecting my network from the list re-establishes the connection. That connection may last for hours or minutes, then it will randomly drop it again, forcing me to manually re-selct it.
It does not auto connect, though it is configured to do so (and does at boot).
Thoughts/suggestions?
My wireless router is a Linsys WRT54G, WEP encryption enabled, SSID Broadcast disabled.
MacBook Pro Mac OS X (10.4.6)

Hmm, interesting.

I have the same router, using WEP, and SSID, same problem (now resolved).
By chance, do you have Bootcamp installed? I was having trouble getting a wireless connection to my MBP. It seemed that the Linksys router wanted to be set up via Ethernet through Windows, because once I hooked up the cable, booted up in Windows XP on my MBP, went to the Linksys admin Web setup page, and entered all the right data, the router thereafter happily communicated through wireless to my MBP in both Windows XP and in Mac OS.
Don't know if it was coincidence or ?, but if you have Bootcamp and a Linksys, you might try going in through Windows to their Web setup page.
Good luck.

Why does wireless on my Time Capsule (2TB, 3rd Gen) drop the wireless network now?

Starting a couple of weeks ago, my Apple Time Capsule (2TB, 3rd Gen) has been dropping the wireless network almost daily. I end up pulling the power cord to restart it. I've had the device for what I think has to be about a year and a half already, and it's been working flawlessly until now. I have it on 802.11N (dual-band), using WPA2, with an average of about 7-8 client devices at any one time throughout our home. The problem doesn't appear to be any one client, since all lose connectivity at the very same time. The Time Capsule LED is still green when it's down, and again restarting it solves the problem. The device is out in a well ventilated area, and doesn't feel like its overheating. Devices using Ethernet to connect are unaffected (other than losing visibility to wireless network elements). It can occurn at any time, day or night, seemingly at random. The Airport Utilty advises that I have the latest firmware version (7.5.2).
Anyone have any idea whats going on? Having similar problems? Fix, workaround, suggestion?

Try setting the wireless to manual and fixed channels.. the auto channel swapping does cause issues.. I would also give different names to 2.4ghz and 5ghz so you know clearly which wireless you are connected to.
But sometimes they do just go bad.. power supply is not robust. They do become unreliable.

IPhone drops wireless network connection

My iPhone can't keep a wireless connection. I can establish the connection as indicated by the wireless network icon, but within less than a minute it reverts to the 3G network icon.
I've tried numerous times to establish a persistent connection, to no avail. During one of those attempts I received an error message "could not scan for wireless networks." I haven't seen anyone else here get that message.
Any ideas what is going on?

I suggest resetting the network settings on your iPhone.
Go to Settings > Reset, and select Reset Network Settings.
This will erase all existing wi-fi network settings stored on your iPhone. This will require re-entering the password for a password protected wi-fi network and reconnecting to all wi-fi networks that you have access to.
If this doesn't work, try a reset, which is done by pressing and holding the Home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release - ignoring the slide to turn off prompt when doing so. An iPhone reset does not affect any data or settings.
If no change after a reset, try restoring your iPhone with iTunes from your iPhone's backup - which is the default selection when doing a restore. If there is a problem with your iPhone's backup, restoring your iPhone from your iPhone's backup will restore the problem. The next step is a restore as a new iPhone or not from your iPhone's backup.
If no change after these steps and if you are in the U.S., time to give AppleCare a call at (800) 694-7466, or make an appointment at an Apple store if there is one nearby.

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!

"Extend a Wireless Network" seems to be... broken?

Hey guys,
Here's the scoop.
I have one Airport Extreme 802.11n that's connected to a cable modem. It's set to "Create a Wireless Network". It's at 5 GHz, and "Allow this Network To Be Extended" is checked. It works fine!
I have another Airport Extreme 802.11n upstairs that's set to "Extend a Wireless Network". I've then entered the network name and password of the original network. It successfully connects just fine to #1, and gets an IP address.
Then, I wander about.
When I get poor signal from the original base station (#1), and I enter the range of the extender station (#2), the laptop switches over to #2 and the network COMPLETELY DROPS OUT.
I.e., I can ping 10.0.1.1, but I cannot access the internet, no web pages can be loaded, etc. I'm stuck -- Airport is dead and I have to power down #2 and reboot.
Has anybody tried using two 802.11n Airport Extremes in this kind of configuration? With both set to 5GHz 802.11n only, and one sharing, the other extending?
If so.. what's your secret? Or is this just a striaght-up bug?
Thanks, Cabel
PS: Don't forget, this has nothing to do with WDS.
