Aironet 1100 dropping connection

M.D. office using several Aironet 1100 mounted on wall in hallways outside exam rooms. Using Motion tablet PC's LE1600 Connection is "dropped" or Lost when moving tablet from room to room. IT guy has reset "switches" channels etc but nothing seem to work. Added more WAp's still have dead zones. Any suggestion?

Here is the some steps which will help you to resolve the issue.
Set the data rates to 'Best range'.
Recommended to set the APs to non-overlapping channels.
Suggested to reduce the size of the cell by changing the power settings.
Here is the URL for the troubleshooting and administration for the AP. It may help you

Aironet 1100 Ping issues poor connectivity LAN

I have setup an Aironet 1100 on our old office, and we never had any connectivity issues.
A month ago we moved to a new location, some new equipment and i moved the Aironet to the new office.
The problem i am experiencing right now is packets drops. The AP is connected straight to out Poe switch. If i telnet into the switch and do an extended ping command, i can see a lot of packets dropping. I've check the interface duplex - speed and everything looks just fine. I have not change any settings on the AP since i moved it to the new location.
What else can i troubleshoot?
Thanks
Zeek

1) Did you try rebooting the AP?
2) Which switch model is it?
3) How is the switch port connecting the AP configured, trunk or access? If trunk how many VLANs are allowed?
4) Check the CPU/Memory on the AP, how much is it?
5) How many clients are connected at once?

Aironet 1310 APs dropping connections

Hello, I have two Aironet 1310s outdoors - one on a boat and the other on a building. I have one ANT24120 antennas attached to each AP. I am trying to determine why I am having dropped connections. Any help would be appreciated.

1) I do not know if anything has changed (at least not with each AP or antenna). I am guessing there is more RF noise. I ran a product called wi-spy and channelizer. There was a lot of competition, so I hard-coded a channel that was consistently lower in noise.
2. I have reset both bridges.
3. I will not have physical access to both bridges till Monday.
4. I am trying to get up to about 5 miles. I am having intermmitent issues while docked as well.

Event log errors after upgrading Aironet 1100

We have upgraded an Aironet 1100 to 12.3(8)JA. We used TFTP for the upgrade and everything seems to be working properly.
However, the event log shows the following message every four seconds: "System running-config write error; configuration failed" This has Error as the severity.
Every thirty minutes another, Critical error is logged "Memory allocation of 900000 bytes failed from 0x22DC78, alignment 0"
I've searched the site and can't seem to locate applicable information on these errors and what they mean. Can someone help?
Thanks!

Oddly enough, this is the most stable AP we have! A PDA can connect to it and stay connnected, whereas our other 1100s (which have not been upgraded and generate the same error messages but only once or twice a day)will permit a device to connect then boot it off after a few seconds to several minutes. We thought the upgrade would make the AP connections more stable but were surprised to see the error messages being generated so rapidly.

Aironet 1100 Default Username and Password not working

I have a Cisco Aironet 1100 series access point (AP1120B) that after resetting to factory defaults the default username and password (Cisco and Cisco) aren't working in the web GUI. I am able to telnet to the AP's IP and log in with Cisco and Cisco but don't know the ENABLE password. I have tried Cisco and cisco and everything else i could think of with no luck. any help would be appreciated.
I also have a Cisco Aironet AP1242AG that is doing the same thing.

Hi Rich,
I assume that you are using the mode button to reset the configurations on these units -- this procedure *should* reset all credentials to Cisco.
If this is still not working, you can try the following:
1) Connect console port and power-cycle unit
2) When IOS starts loading, hit ESC key twice to get to the boot-loader prompt
3) At the boot-loader prompt show a directory of the flash filesystem (dir flash:)
4) Delete or rename the files "config.txt" and "env_vars", then boot the system ("delete flash:/config.txt" "delete flash:/env_vars")

No IP address on Aironet 1100 AP

We have 5 Aironet 1100 series APs deployed in one of our buildings. A few days ago, 3 of them showed down in our monitoring. The next day the other 2 showed down. When I go to the switches that they are attached to and do a show cdp neighbor detail, I see all the access points but NO IP address. Also, when I went to to site, I can connect to the APs via wireless and be on the network just fine. We have static IP addresses assigned to them. However, they are not pingable and do not show up in the ARP table of the switch.
They have been running a couple of years without changes.
Any ideas?
Thanks
Carl

Probably a dumb question but have you rebooted the AP's? Also, are they drawing power from a powered switch or do they have their own mains power bricks attached?

Aironet 1100 as repeater: radio disabled!?!

I followed the directions according to the configuration guide 12.3(8)JA but the repeater never connects to the root AP and I notice the radio is "disabled" after setting the AP in repeater mode and it will not let me enable it. Any ideas as to why I cannot get the two Aironet 1100 AP's to connect and why the radio would be "disabled"?
Thanks

I have no security in place and the SSID are the exact same. I have the AP's about 15 ft apart so the coverage should be fine. The parent mac address is correct. Any other ideas? Thanks in advance.

Linux clients not associating with Aironet 1100

Does anyone know if there is an issue with a Linux client associating with an Aironet 1100 using WEP? Windows clients are connecting fine, and the Linux client connects to Linksys branded APs with WEP no problem.
Aironet config:
IOS 12.3(2)
16 AP on same SSID, different cells
128-bit WEP
Linux client:
Dlink Airplus DWL-G630
Kernel: Slackware 2.6.12.2
Commands used to associate
ifconfig ath0 up
iwconfig ath0 ath0 mode managed key restricted [2] {key}
dhcpcd ath0
After bringing up the ath0 interface, and running the iwconfig, you can see the iwconfig settings are sticking, but it seems to be jumping around APs when you watch the MAC of the AP. It goes from a valid MAC address to FF:FF:FF:FF:FF:FF and then to another valid address, and back again. This does not happen on the Linksys AP.
Any ideas?
Thanks,
Andy

Try entering the key (on the Linux box) as hex.
Most of the Windows client software lets you enter the key in ASCII ... some client software requires that you put in the hex translation.
You can check the logs on the 1100 to see what the failure message is ,,, but I'd bet it'll be something along the lines of "Invalid Key"
Good Luck

Aironet 1100 RED-GREEN-RED lights on

Hello,
my Aironet 1100 has the red-green-red leds on, how can i replace the IOS, how can i access it, i'm having problems using Ethernet?
thanks

Just had the same thing happen. I hooked the AP up to a laptop via ethernet cable, held the Mode button while connecting the power to the AP, and used tftp to transfer the image back to the AP.

Aironet 1100 won't show IP Addr. w/ IPSU

I am trying to set up a Aironet 1100. I enter the mac addr. into the IPSU and get a error - device does not answer. I've reset the device, ng. Tried 2 different computers, ng. I cannot get to the config. page. Any ideas?

Plan B: Get yourself a copy of tftpd from here:
http://tftpd32.jounin.net/
A very lightweight TFTP & DHCP server (amongst other things). Install on a PC and connect to the new AP with a cross lead (or in such a way that the PC and AP are isolated from the main LAN). Start TFTPD and configure a DHCP scope, power on the AP and watch the TFTPD log screen. Connect to the AP with a browser and give it a static address on the main LAN.
Plan C: Connect a console cable to the AP and reboot it, watch the boot process carefully and you'll see the IP address it leases.

Aironet 1100 with Static Address

Hi All
I have taken over some access points from a company which were providing our wireless service and have not yet received the IP scheme information.
I need to get onto one of the Aironet 1100 access points to see what the config etc is.
I will only be able to take it down for a few hours, how to I actually connect to it.
I am pretty sure it is configured with a static IP address which I do not know so is there anyway of connecting to it without using the Reset to Default method obviously!
I have tried IPSU and a hub but no good.
All replied gratefully received!!
Darran

Thanks for the replies guys but it hasnt solved my problem.
Looks like it's not a static address after all
I have done the following
1. Plugged the AP into a switch on our network and connected to it wirelessly. I receive an IP the very same as if I was plugged into the switch directly and when I do an IPconfig I get the very same info as if I was plugged directly in. Still cannot find the AP IP Address though.
2. Plugged the AP into a switch on our network and connected to the switch and did a show cdp neighbour, the access point does not show up, only other switches.
3. Read the user guide and connected my laptop directly to the AP with a CAT 5 cable and gave the laptop an address of 10.0.0.2 . The AP does not seem to revert to 10.0.0.1 as suggested in the manual.
4. I have tried to run the IPSU under all the above conditions, searching by the mac address of the AP but it has not received anything.
ANy other ideas, Im at my wits end!!

Dropped connection with 1130ag

Please let me know what kind of information you would like in order to help. I currently have 3 Aironet 1130ag's. One is wired and broadcasting ssid wireless003. One is wired and broadcasting wireless 002. The third is a wireless ap that is pulling from the wireless 002. I'm not sure if I have a setting wrong or somewhere and am not very experienced with these routers.
We care getting dropped connection specially from the wireless ap. There are so many settings I don't know where to start. Can you guys please point me in the right direction for what you need?

I tried to open your files, but they are not showing up right. Save them in a text file format if you can. Anyways.... the AP you setup as a reapeater... well... not so much a good idea. A repeater will automatically cut the throughput in half and perfomance will always be sort of degraded. I have used repeaters back in the days, but what users expect from a wireless AP, you really can't get that from an AP setup as a repeater. If you have one user and the users is near the repeater, then that might work, but you will not get the same results as a true access point.

Cisco Aironet 1100 series wireless access point software update!

Hi,
I have a wireless network using 2 cisco aironet 1100 series access points.
From time to time I have problems with connecting a device (Laptop,PC,)to the wireless network.There are onther wireless netwotk that operate around and might be using the same channel.Someone else created the wireless network and I do not know how to access it now to check the configurations on change something.
I cannot conncet my iPhone to the network and I beleive that a software update might solve the problem but I do not know how to do it and where to download it from.
1. How can I update the software and where from?
2.How can I ensure that thare are no interferences and conflicts?
3.How can I ensure that no onther wireless network around is using the same channel?
Thank you in advance.

Sounds good to me. Are you having problems?

New time capsule+new airport express=daily dropped connections

I have a new 2 TB Time Capsule and a new Airport Express that I puchased to update my old set-up of an Airport Express and Airport Extreme.
I have the TC set-up as the primary base station in the back of the house and the airport express set-up to extend the network in the front of the house. I was getting constant disconnects up front for the first several days so I finally exchanged the new AX for another one thinking maybe the first one was faulty. I reset the TC back to factory defaults for good measure and re-set up my network the same way with the new AX.
Two days with no disconnects, thought it was fixed, and then it started again...no joy. Not as often as with the first AX, but still it happens 2-3 times a day and always up in the front of the house while we're on our MacBook Pro or MacBook Air. When this happens both the AX and the TC have green lights and full bars of connectivity show in the menu bar, but yet no internet access. The only way to reconnect is to restart the AX. I have noticed too, that when this happens, the Airport Utility does not show the TC at all...even though it's light is fully green and it should be there, it just shows the AX until I restart and then both show up again.
I've tried changing the channel from automatic to a specific channel but this really doesn't change things much. Now I'm starting to wonder if something is awry with the TC. I've also noticed that it sometimes fails to back up because it can't find a connection to my iMac which is right next to it in the back of the house.
So far this upgrade has been more of a downgrade. Any help would be greatly appreciated!

Just an update and still seeking some advice for this situation...anybody?
I tried re-setting both TC and AX to factory settings and re-configuring. Still get at least 3-4 dropped connections up front on a daily basis; however, TC has been connecting successfully and backing up my iMac, so at least that seems to be ok.
Still the same situation with the TC not showing up in Airport Utility every time the network connection drops happen...just the AX is seen until I finally have to restart the AX and then both can be viewed in Airport Utility and the internet connection is restored. Sometimes I can restore connection by simply toggling my airport access on and off in the menu bar of my MacBook Pro, but more often then not, I have to restart the AX itself to get back online.
Is it possible that this could be an issue with the TC? Somehow it might be dropping the connection to the AX? I can still exchange it for another if this may be the case. I'm already on my second AX thinking that the Express was the problem initially.
So far, nothing seems to help the situation. About the only thing that I haven't done is configure the AX to just join the network rather than extend it...but that would be defeating the purpose of why I bought it in the first place (to stream iTunes and extend network).
I never had issues with my old set-up, but then I had it configured as a WDS because I didn't have the option to "extend" the network as it was an older AX and Airport Express.

10.7.3 MBP Wifi Problem - Endless Timeouts & Dropped connections

I've been reading around here a bit already and so I know many other people are having Wifi issues with Lion, but given that there are so many discussions and so many pages of talk, it's hard to go through it all, and using the search I haven't found anything that's quite similar to what I'm experiencing, so I'm starting a new topic...
Basically, I've got a late 2006 MacBook Pro, installed 10.7.1 (form 10.6.8) on in back in Aug 2011 and everything seemed to be fine. I updated to 10.7.2 sometime in Jan and still didn't notice any issues, but wasn't using Wifi at all at the time.
Then in Feb I moved and started using wifi (with a Cisco N router), and noticed that often, the system would not automatically reconnect to the network after waking up from sleep. Just selecting the network manually worked on the first try every time though, so it wasn't so bad.
At the end of April, I finally got around to installing the 10.7.3 update. I read it was supposed to fix wifi issues and so was looking forward to it. It installed fine and didn't seem to cause any problems...
2 days later I moved again (to India), and all **** broke loose... Now, I can rarely connect to wifi (a Beetel G router, configed with WPA). Around 25% of the time, the network won't show up in the list (despite being a clear 5ft from the base station), and when it does show up, 95% of the time I get a "connection timeout" error - often immeadiately, but sometimes it takes about 10sec to respond. On the same network, 2 Win 7 Dells and an iPad 1 all work flawlessly - it's not the router...
One the occasions that I am able to connect, it usually works fine, but if I put the computer to sleep and wake up again, there's no guarentee that the connection will work again - it's back to the lottery. And sometimes even when it's connected, the wifi stays (according to the menu indicator) but the internet connection disappears (to the point I can't even ping the router - 100% packet loss, let alone any internet server)
I've tried zapping everything I can think of (PRAM, SMC), repairing permissions, clearing the remembered networks from the System Prefs, deleting old Locations and creating new ones etc. I have a clean install of 10.7.1 that I booted off of, but it still had the same issues!

I'm pretty savy with computers and have dealt with all kinds of stuff before, but this one is beyond me, and is really annoying! I konw my machine is old, but it was totally useable up until these Wifi issues, and now wifi is basically useless.
From what I've read, it seems like its a driver issue with the Atheros card in my machine, but most people seem to be complaining about dropped connections (mine rarely drops) rather than timeout connection issues. I've also never had the "hardware not found" issue that many people have, so I think this is something different.
Anyone out there have any advice? I'm getting close to losing it with wifi since the update!

Sorry - to add:
I don't think it's a question of WPA vs. WPA2, or even channel number - I have 2 identical routers here and neither work (both default to WPA Ch 11) but I changed one to WPA2, new SSID, various channels and still had the same problems.
Another thing to note that should be irrelevant, but who knows: the Firewire controller on my machine died back in Fall 2010 - to the point where the system won't start-up unless I remove the IOFirewire***.kext from /System/Library/Extensions , and as soon as I do that, it works flawlessly (minus Firewire). It meant I had a **** of a time installing Lion becuase I can't boot off the Recovery Partition (which has the drivers baked into it), but by cloneing my HD, installing Lion onto the clone via a borrowed machine, removing the .kext's and cloning back, I got it on and everything seems to be fine otherwise... I posted about that problem before, but never got any answers. And it wasn't just me, my father has a late 2007 MBP and the same firewire issue happened to his within 5 days of mine (not a power spike - I think it was shortly after some system update if I remember correctly).
