Wireless mesh backhaul drop every 2 -3 minutes

I have 4 1242 A/G (A is the backhaul and G is for clients, NO WLC) in a mesh with 1 as tha RAP and 3 and the MAP.  All aps have the same antenna 2.4 has patch 7.5dbi and the 5.0 has a 6dbi omni.  The syslog shows that the backhaul is dropping every 1-2 mintues because of maxreties.  The distance between the RAP and MAP is about 300ft, and the AP are about 12-15ft off the ground in a indoor parking garage for 100-40ft mass transit bus.(40 passangerbuses).  What could be causing the backhaul to drop?
Thanks

Was this working before and just now stopped working ?

  • WRT54GS wireless connection becomes unreachable every 3-6 minutes

    I just got signed up with COMCAST (TV, Internet, and VOIP). The Linksys WRT54GS is connected to the COMCAST Internet-VOIP box. Everything is working fine except the wireless. I bought the Linksys WRT54GS and when I run "ping 192.168.1.1 -t" from my latop via the wireless the connection becomes unreachable every 3-6 minutes. When I "refresh the list" from the laptop the connection is working. The wireless is using WEP security, the strength during the test is 3-4 bars. The problem has been seen in the same room (7 ft away) with 5 bars. I've not yet contacted COMCAST because at this time my thoughts are that I've misconfigured the Linksys. Allen

    Allen:
    If you purchased the router elsewhere, save the call to Comcast. They won't help you.
    Try changing to different channels in the router. There may be interference in your area that causes the drop. I would point out that a dropped ping occasionally is normal, although when it negatively impacts your ability to stay connected, you'll want to find the issue.
    The default channel on the router is 11 I think. Try going through all the channels from 1 on up and running each one for a period of time. Your wireless card doesn't need any changes made; it should reset itself to the new channel within a few seconds.

  • Guest-wired access connections drop every 1- 2 minutes

    I have an interesting problem.
    My connections to the guest wired access drop consistanly every 1 -2 minutes. There are no drops in the mobility between the WiSM and the 4402 anchor in the DMZ.  DHCp is served from the 4402 DMZ controller as well as thier authentication.
    When a user connects to the guest wired access vlan some times they obtain a 169.X.X.X address and after several tries they get the proper 192.168.x.x addres. The user get thier IP address and get the redirect login. They maintain thier internet connection for only 1 - 2 minutes.
    DHCP on the 4402 is set for 4hours
    Any thoughts ?

    Ouch, the forums ate my formatting for that first post!
    Thanks for the reply Ray. I should mention that this is a shared house, not a family home, so I cannot always access the devices. I'm the one on the ethernet connection and I've gone into my ethernet adaptor's settings to change my IP address to a static number just below that of the DHCP range whilst leaving DHCP enabled for everyone else. After restarting my computer the connection's still dropping.
    Haven't had a chance to reset the hub yet, if that's necessary, as other people are using the connection at the moment.
    I do have the admin password for the hub but I'm under the impression a static IP address would have to be set from the devices themselves which I can't access - or can I use Home Network > Devices, check "Always use this IP address" then disable DHCP?

  • Wireless Mesh/Backhaul question.

    We have a customer who wants a wireless bridge/mesh link between two buildings. They want as much throughput as possible, better than 802.11b/g 54Mb for preference. We've identified Cisoc 1552E or I APs as suitable devices but we can't tell from the literature what sort of bandwidth we can expect over the backhaul link, will it use 802.11n speeds or are we stuck with b/g data rates? Any advice would be much appreciated.

    22mb is the supported data rate I think. Why not look at the Cisco ExtendAir radio. It is 5ghz non-wifi bridge with up to 160mb of throughput and 5 9's of uptime.

  • GPS Dropping every 10-12 minutes

    Prior to today, my GPS worked great, the map worked great.  Since yesterday, the phone says lost GPS signal, every ten minutes. I restart the map, and bang, it is back for 10 minutes then it drops again.  I does not matter where I am, it does it now all the time. And this in an area where i never had an issue and my very old Garmin Nuvi has a strong signal.  Any ideas?

    The first thing I would do, is take out the battery and leave out for 5 min and then reinstall it and see what happens...
    Sometime if we leave our phone on 24/7 it seems that the phone is asking for rest for lack of a better term.

  • WIFI drops every 1-2 minutes MBP Retina 2013

    I've searching this forum for this issue but no solution helped me (deleting network login from keychain, etc)
    I hope that I can find useful advice here.
    MBP Retina Early 2013, 2.7 i7, 16 GB, 512 GB.
    I've bought it 1 week ago and 4 days after it started dropping connection every few minutes (sometimes it works fine for 0.5-2 hours).
    It is so disturbing that I cant evenly use web.
    Is it hardware issue or software? And how can I fix it?

    Take it back to the store, you have like 90 days of free hand holding and they also check the machine for hardware issues.

  • Wireless radio turns off every 2 minutes

    I have a Thinkpad Z60t, running Windows XP.
    I have the physical wireless switch on the side panel set to the on position (i.e. to the right).
    Initially, I am able to connect to any wireless network without a problem. However, after about 2 minutes of not actively using the internet, the green "wireless radio" status light on the front panel turns off and I lose my internet connection. I then have to do "Fn + F5" (or ThinkVantage button -> Manage My Connections -> Power On/Off Wireless Radios) to turn it back on (and get the status light to be green again). I then have to reconnect to the wireless network.
    I believe this is a common issue. I have tried several suggestions I found on other forums, including ThinkVantage button -> Manage My Connections -> Select Location Profiles -> Open Access Connections -> Configure -> Location Switching -> UNSELECT "Enable automatic location switching". This method actually seemed to work for a few hours, but then stopped.
    I am certain that my wireless network is stable - my roommate's laptop does not lose the signal every 2 minutes like I do. I think my laptop's wireless radio automatically shuts off after 2 minutes of no use, and this feature needs to be disabled somehow.
    Please help. I am getting frustrated of having to manually reconnect every 2 minutes.

    Solved!
    Go to Solution.

    open control panel, go under system, hardware/system property, then go into the device manager.
    Under the wireless card property (right click on the wireless card and select property), there are settings for roaming aggressiveness, power saving and power output.

    Paul,
    We were on version 6.1.0.483 (Windows Masters), with 3.1.0.05 agents which kept restarting every 11 mins....  turns out for us it was a bad license on the master.  Once we received and installed the new license, the problem was resolved.
    Hope this is the answer to your problem.

  • Every 10-15 minutes Firefox 3.6 cannot load pages (from bookmarks or links) and must be re-started

    Every 10-15 minutes I find that clicking a link in a webpage or selecting a bookmark will elicit the white error page message that the target page could not be loaded; usually (but not always) I will be told that my internet connection "does not seem to be working". Other programs accessing the internet are not affected. The problem usually solves itself if I close FF, wait 2 minutes, and start it again, which is not really practical. The problem occurs both on a home network (wireless) and an office network (ethernet). FF3.6 has been problematic since I updated to it (esp.: slow to open); I have tried un-installing and dropping back to 3.5, but FF has twice updated to the most recent version (6.7, then 6.8) without asking whether I wanted this.
    == This happened ==
    Every time Firefox opened
    == I updated to Firefox 3.6

    Just an addition: when the connection drops out, the Windows 'error' sound occurs.

  • Time Capsule reboots about every 20-30 minutes

    Hey all,
    I have a Time Capsule (about 6 months old) with a cable modem plugged into it.  My wifi is being extended by a brand new Airport extreme.  I have 4 computers connecting via wifi to it.  About every 20-30 minutes the wifi signal drops from the TC, confirming this with iStumbler, and the TC has to reset.  I haven't gotten a back up to complete in quite a few days due to this.  Any ideas?
    I have unplugging all ethernet devices, hard reseting it to factory defaults, and of course power cycling it. 

    I would firstly go back to 7.6.1 firmware.. the latest firmware has some horrible bugs .. especially in cases of extend wireless.
    To go back you simply hold down the option key whilst selecting version.
