Aironet 1310 Bridges keep losing connection

There was a similar thread about this last year and I tried what was listed in there to no avail. I have 2 Aironet 1310 bridges, one as a route bridge and the second as a non-route with clients. These worked great for nearly a year, we had no problems keeping the connection up. They were not connected for the last few months but nothing was changed on the configuration, when I put them back up they reconnected just fine and worked for about an hour, not they randomly disconnect with the same message in the log entries below. Is there something wrong with them now? The are using the same antennas as before and are in the same exact locations.

I am not at the remote location any more, but the route bridge had a signal of -78 dB and a SNR of -22 dB. The non-route has -77dB for signal and a SNR of -22 dB. The location has line of sight, over water with nothing in the way.
Since I last posted I changed the fragmentation and RTS thresholds back to default from 4000 and it has been up for 24 hours now. I am hoping that it has made the difference.

Aironet 1310 bridge does not reestablish connection

We have an aironet 1310 bridge installed (root/non root) where the non root drops sometimes the signal when the morning sun is in direct line with the link. This blackout problem is known. What bothers me is the fact that the bridge does not automatically reestablish the association...
Once it has been lost we have to restart the Air 1310, then it re-associates. Is there a workaround or an automatism?
Thank you for your suggestions.
Bert

This should be automatic. I had a client have this problem once, and we found that the problem was actually with the 1310 being configured in diversity mode. The 1310 would disconnect in tough weather conditions and try to connect to the little metal stub that comes on the bridge. The signal was too weak to establish a good connection, but for some reason it would not switch back.
So check to see if you have diversity mode enable, and disable it if it is. If that's not the problem, I'm not sure what it could be. Have you tried upgrading the IOS?

Configuration of a Point to MultiPoint link with Cisco Aironet 1310 bridges

Hi All,
The previous problem of which I started another conversation here:
http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=General&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddba023
somehow dissapeared. It could have been a problem of interferences.
I have another issue with other (multipoint) wireless WAN link, which I hope has a solution.
On the central node, we have an Cisco Aironet 1310 bridge configured as root-bridge. It has a panel of four vertical polarity 17 dBi panel 90? antennas, with more than enough gain (there is a 250 mWatts 802.11 b/g amplifier, before the 4-way splitter) and excellent line of sight to three remote bridges.
The three (03) remote bridges are also Aironet 1310 models, confidured as non-root-bridges.
The problem we have is that it seems that when the three remote links operate concurrently the amount of lost packets is huge. When I shutdown the radio interfaces of two bridges, the remaining bridge makes an excellent link with the central node.
It seems that some hours are more critical than others, also the links operate much worse when there is some (small) network traffic in them.
I have read the 1310 manuals, and I can't find a sample configuration for point to multi-point links.
Does someone knows what radio interface configuration should I need to use to establish better quality communication?
I mean, perhaps the 1 x root - 3 x no root configuration is not recommendable for the multipoint link configuration.
Any hints will be welcome.
Best Regards,
Igor Sotelo.

Hi All,
Thank you for the information. I configured the distance on the root bridges, but the links showed instability.
I'm using a bi-directional amplifier. It has two pieces. According to the manuals, one is installed indoors, the other outdoors. I'm not sure if the indoors piece has the transmition module or it's only the injector.
We could establish connection at 7 km (around 4 milles) distance from the central point, using 24 dBi antennas on the other side.
However, we have issues with a near located point that is only 1.2 Km (around 0.8 milles) away and has a 13 dBi integrated patch antenna. The signal strenght value we get there is in the -62 to -68 dBm range, and is noticiably (5-10 dBm) lower than the strenght we get at other points of the link. And I have trouble establishing a high quality link with that point, using OFDM modulation. I tend to think that if I remove the amplifier I'm not going to reach that point at all. The EIRP on the central iste is 34 dBm / 2.5 watts, without amplifier it would be 26 dBm / 0.4 watts.
On the opposite sites the EIRP is 33 dBm / 2 watts using CCK or 28 dBm / 0.63 watts using OFDM.
When one looks at the central site from that point, an Motorola Canopy with passive reflector (EIRP 48 dBm or around 64 watts) can be seen. It doesn't have the same direction, but the opposite site must be large distance and could interfere with my wireless network. Attached is an amplified photo of the view. It's safe to assume that the Canopy operates in the 2.4 GHz frequency range.
Once I connect the point at 1.2 Km, the multipoint link loses its quality, and soon the lost packets get too frequent.
The CCK seems to be much more interfered than OFDM, I guess because of that canopies.
Another thing I'm wondering about is if the Aironet 1310 can continuosly switch CCK-OFDM over the same point - multipoint link, without losing packets.
What other parameters should I tweak? Is there a way to avoid interferences fromt the canopy?
I would like to apply 100 mWatts local power using the radio with OFDM, but it seems that's not possible.
Best Regards,
Igor Sotelo.

External drive conntected to Time Capsule keeps losing connection

I've been having this problem since I bought my TC over one year ago. Other than this everything works fine (aside from the occasional need for a restart).
I have an external 500GB drive attached to my 500GB TC via usb. I use the TC strictly for backups and the other drive to host my media files. When I want to use those files I switch on the drive. Only about half of the time does that work. When it does work everything is fine. I see the drive in the finder as expected.
When it doesn't work, I can see the drive name in the finder. But if I click to go into the folder, I get an error saying that the connection cannot be found.
It shows up in the Airport Utility as normal.
Powering the drive off and on does not help.
Relaunching the finder doesn't help either.
The only way I can connect to the drive again is to either logoff and log back into my mac, or restart the TC.
It seems that my computer is remembering some kind of network disk mounting settings that don't get refreshed when I turn on the drive, but then do get refreshed when I logoff and back in. Does anyone know how I could force that refresh to happen? Has anyone had this problem before?
Any suggestions would be much appreciated
PS all my software and firmware are the latest.
Thanks.

LaCie external hard drive keeps losing connection to Windows 8.1 computer

Hello all,
My LaCie external hard drive (Rugged version) seems like it keeps losing connection to my brand new Windows 8.1 laptop. The laptop is an HP Pavillion 15-p 133cl TouchSmart Notebook which I just got today. Basically, every few minutes, or if I nudge the external
a bit, the computer will seem like it disconnected and reconnected to the external hard drive in a split second and bring it up in the Windows Explorer. This external hard drive doesn't show any problems connecting to any other computer, but it has occurred
with 2/3 ports on this computer so far. I'm a bit worried, because I definitely DO NOT want the files on this external to get corrupted in any way. What should I do? Thanks a bunch.

may I know your external HDD model, to check which USB version to isolate power and cable connection issue
if this is USB 3.0 try to attached at USB 3.0 at your laptop, your laptop has 2 USB 3.0 and 1 for 2.0, for external HDD with USB 2.0 sometimes need more power / more than 1 connection, sometimes the power will loose
but since the trigger it will disconnect if you nudge the HDD, I suggest back up data to your laptop first, try to change with other data or power cable, try also update your laptop chipset
try to check with other device to isolate port issue
may I know if you are using other PC, did your external HDD also will disconnect if you nudge it?
contact your external HDD manufactured to get some suggestion

Why does my iPad2 suddenly keep losing connection on facetime?

Why does my iPad2 suddenly keep losing connection on FaceTime and tries to constantly reconnect?

Does it happen anywhere that you use FaceTime or only in your home WiFi network? If it happens with your home network, have you tried power cycling your router? Unplug it for about 30 seconds and then plug it back in.
Turn WiFi off and on in the settings. Reset the network settings.
Have you tried any troubleshooting steps at all?

Why does my mouse keep losing connection every minute

why does my mouse keep losing connection every minute, its not the batteries

I'm having the same issue. Every so often it loses connection then re establishes. This goes on repeatedly.
If you change batteries while the computer is still active then it takes for ever to re connect.
Can't wait until someone replies to your question.

Why does my mouse keep losing connectivity

My magic Mouse (came with the system) keeps losing connectivity. It seems that whenever the mouse has a period of inactivity such as when I am using the key board, it loses connectivity and I have to double tap it (two fingers) to get it to reconnect. Battery is >80%. Is this normal or is there a setting that can insure it stays connected? I appreciate any advice even if it is I have to put up with this annoyance. Thanks.

BDAqua
Thanks for the response. My WFi is a Linksys E2000. Because of the number of messages in the Console I will have to wait until the next time I lose connectivity and then check for messages in Console to see if there are any clues to what is going on.

Deskjet 3520 keeps losing connection to Mac

Last night, I installed an HP Deskjet 3520 printer to use with my desktop Mac (which is using OS Yosemite). I have an etsy shop where I sell prints of my illustrations, so I often have to print out multiple files in a row. When I installed the driver last night, I was able to wirelessly print the test page, but after that, I could not print wirelessly. Instead, I used the USB connection, which worked fine. I printed a round of prints and everything worked fine.
This morning, I need to do some more printing, and my Mac reported that there was no connection to the printer (even though the printer was connected via USB). I deleted the printer from my Systems Preferences Printers and re-added it, and I was finally able to do my printing (still not wirelessly).
Now, tonight, I have tried to do more printing and the Mac reports that there is no connection to the printer, USB or wireless. I tried deleting from Systems Preferences and re-adding again, but that didn't work this time. Then, I tried resetting the printing system, uninstalling HP, and re-installing the driver. Now, I'm at the part of the installer where the device needs to be configured and I am receiving the message:
Device Not Reachable. The wireless network settings were successfully downloaded to your device. However, your Mac was unable to locate the device on the network.
I don't know what keeps going wrong! The little screen on my printer says it is connected to my wireless network AND I am still connected via USB so I don't know how the device would not be reachable. I also don't know why the printer would keep losing connection with the computer every time I need to start printing again. Please help!!

Hi @tylertot
This is in deed a little strange, but I'd like to help! Some of the steps I am going to offer are steps you have done, but I;d like to perform the following steps in the order presented to see what happens. Please give the following a try;
Leave the printer on and unplug the power cable, also unplug the USB cable. Restart teh Mac and then plug the printer power cable back in. You can also go ahead and reconnect the USB cable.
Reset Printing System - (I know you did this already, thus you know how, but here are the steps for others who may view this thread)
Click the Apple icon (   ), and then click System Preferences.
In the Hardware section, click Print & Fax/Scan. The Print & Fax/Scan dialog box opens.
Right-click (or  Ctrl  +click) in the left panel, and then click Reset printing system…
Click OK to confirm the reset.
Type the correct Name and Password.
Click OK to reset the printing system. The Print & Fax dialog box shows no printer selected
Note: This will remove all printers in the print and Fax/Scan, any printer removed can be re-added later by clicking the plus (+) symbol.
Repair Disk Permissions - I don't see that you have tried this yet, and this step might be crucial to resolving the issue.
On the Dock, click Applications, and then click Utilities.
Double-click Disk Utility.
Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
Click the Repair Disk Permissions button at the bottom of the window.
Once the repair is complete, restart the computer and add the printer back.
When you add the printer, please ensure you are using the HP driver. You can add the wireless or the USB, or Both. If you ad both, I suggest adding a name to identify one connection from the other.
Select Add other Printer or Scanner
Select the printer you are adding and next to 'Use' you can the printer driver
You can see in the image above where the name section is, if you add both connection types simply add USB to the beginning of one of the names.
Adding both printers and naming them to help identify them helps when it comes time to print. When you print something you can choose the printer with the appropriate connection type. For example, you can choose the wireless driver ad if you get an offline message try printing again but choose the USB driver. If the USB one works you will know the issue is related to the Wireless connection, and if it doesn;t then the issue is related tot he operating system. Really this is just a proactive troubleshooting attempt in case issue arise in the near future. If you only want to add one connection type that is okay too.
I look forward to hearing from you.

I have an iPad 2 connected to airport express so that I can play and change music whilst I am teaching ballet class. Recently, I keep losing connection and the airport express gets quite hot. I have alway used Archos but changed to Apple for reliability!

I have an ipad 2 with airport express that I use to play and change music whilst teaching ballet class. Recently, I keep losing connection and the airport express appears to be getting quite hot. I did use Archos but changed to Apple for reliabilty! Can anyone help or should I just buy a new airport express.

I agree that it's probably interference. Only other possibility, since you mentioned it, it overheating. Is the express situated so that it is well ventilated? That is to say, not buried under other equipment and laying on its side? What does the status light do when you lose connection?

2008 Mac Pro keeps losing connection to my Plex Blu-ray burner

my 2008 Mac Pro keeps losing connection to my Plex Blu-ray burner. It is installed in the second optical drive bay. If I power down, pull the connections to the drive and re-attach, the drive is again recognized on boot. A day later, no drive found. The first optical (top bay) drive never loses connection. Any thoughts?

Disable drive sleep in the Energy Saver system preference.

HELP: Keep losing connection!

Just got an airport express last week to replace our philips wireless router because my wife keeps losing connection with her ibook g4. But alas! We are having the same problem with her computer. My macbook pro is connected, but I have had to reset several times already to try and get my wife connected. This is really frustrating, as there are no clear message as to what the problem is. And when I reset sometimes, we both get connection but could not connect to the internet. Do I have to sacrifice security for stability? Because everytime I make the network secure, we always had problems.
Please, I'd appreciate any help.
Thanks.
macbook pro Mac OS X (10.4.8) ibook g4

sagada, Welcome to the discussion area!
Check for other devices that use 2.4 GHz. These could be directly interfering with your wireless network. Remove those devices if possible. If that is not possible, try changing the channel used by the AirPort Express (AX) until you find a channel that works better or you run out of channels.

Keep losing Connection I Phone 4s

Ive had this problem on and off for a few weeks now ive got signal and my 3G is on my phone keeps losing connection to the internet weather app facebook and the app store it seems to have happened since i updated my phone to 6.1.3 it comes back on if i turn my phone off and back on but this get really annoying the past to nights its lost connection over night just wondering if any one else is having the same problem and know when an update is due its says my software is all up to date??

HA d you tried the very quick trick that seems to work for some - the cycling of the "Airplane Mode" switch on the settings first page. It DOES reconnect here in Barbados (carrier is LIME ) and will hold for at least a week or more... Suspicion is that the carriers may 'fiddle' with their own networks as the upgrade and modify things.... And some phones are very sensitive to slight changes in protocols. A reboot often doe s not solve this problem, because the phone will reboot to whatever settings were in use at shutdown, but Airplane Mode on then off forces a refresh....without doing a 'reset network settings' which will cause the dump of stored wifi networks and passwords.... I have had to apply this 'fix' ( with success ) to both my and my wife's iPhones 4s, using ios 6.1.3 , more than once ..... Best of luck with it and please post the result !!
