Cisco Wireless :: 6509 IPads Not Staying Connected To APs
Apr 19, 2012
All, I am the wireless administrator for a rather large school district in Oregon, and we are seeing numerous issues with iPad's connecting and staying connected to our lightweight AP's in an HREAP configuration. Our iPad carts have about 20 iPads a piece and an AIR-LAP1142 supporting them. We have no issues with getting non-Apple products to connect and stay connected, but for some reason the iPads are creating a major issue. We currently run 8 4400 WISM blades via two 6509's, running code 7.0.116.0.Our AP's are running 7.0.116.0 as their primary software and their IOS is 12.4(23c)JA2.
My Sony VAIO VPCEH36FX laptop has trouble staying connected to wireless for long. I've only had it for about a week now and it's been happening since Day 1. It alternates between trying to connect, to being connected but with limited access, to not being connected at all. However, if I unplug the router and plug it back in, the laptop will work fine anywhere from 30 minutes to a couple hours. But after that it goes back to trying to connect/limited access. I doubt it's a problem with the router, as all other devices in the house work fine with it. It's a Linksys Cisco router. It doesn't have a password or anything.
I have just bought my xps 12 in the last week. I was able to connect to the internet and hold a connection.
Then I came home to my apartment which provides wifi free to the building and i cannot stay connected and sometimes cannot even connect. I do not have access to the router but other devices using the wifi here are able to hold a connection. The network is a public one btw (don't know if it matters)
I have my power set to max performance for network connectivity and like i said this computer is less than a week old.
I have a new HP dv6-3250 (I think that is the model number). For some reason it will not stay connected to my Wireless internet. It recognizes that it is there but it will not connect.
We just moved and got a new ISP, and I have not been able to get a good connection through wifi. When I am connected, it usually goes really slow, and drops every so often. It says that I have 5 bars. I sometimes get a decent connect, but it only lasts a couple minutes. My sister has no problem connecting to the wifi at all on her laptop. I also have never had any problems connecting to wifi before, and I have been able to connect and have decent speeds at my friend's house. I'm on windows 7 the router is a Motorola
I recently bought an AT&T hotspot elevate and my iPad, iPhone and wii connect to it with no problem. I also have a dell Inspiron laptop that will connect, stay connected for about 30 seconds, disconnect, connect back and continue the cycle. Trying to figure out why it won't stay connected.
Ever since I started using iPads at the house I have had to reboot the router about once a week because the download speeds drops by approximately 90%. As soon as the reboot completes all is right with the world for about another week. During the course of the week, but not all at once, we will have 4 iPads, 3 iPhones, 2 laptops and one desktop(wired), a Verizon signal booster and house guests. I have updated the firmware.
I am trying to test (if possible) the idea of having 2 6509-E switches connected directly to each other while using VRF-lite (Sup 2T). The idea is to have 3-4 separate networks. For example Net-A, Net-B,Net-C, Net-D. There is no PE router*, just these two switches. Also, there sin't any other access layer switches. All users connect directly to the 6509-E's via switch 48 port switch blades.
Net-A and Net-B on separate VRF's, but able to talk to each other. Net-C and Net-D* on separate VRF's without being able to talk to any other. Net-D* will have a PE since it comes from an external network. This is something I would like to test in a lab environment, but I am not familiar with VRF's.
We have a 6509 Sup2 at our ISP edge with fiber connection to ISP. I am planning on replacing the 6509 either with 7206VXR-GE2 or ASR 1002.
How do I find out what GBIC is installed on my Sup2 right now where Fiber cable is connected?What GBIC/SFP will be compatible for this on 7206VXR or ASR1002?If I use SFP do I need to change the cable connector?
A customer of ours has the following access points and wireless lan controllers on site. They want to use the Apple Bonjour service with Apple TV's and iPads. I have enabled multicast feature of the 5508 globally and one the SSID.The Apple TV has an ethernet connection and the iPads connect over the wifi. The Apple tv is on the same subnet as the iPad's - the Bonjour features do work for approx 5/10 minutes then it stops working for some reason. The Access Points plug into a Cisco 2960 Layer 2 switch, the 5508 controllers plug are in LAG mode and plug into a Nortel Layer 3 stack which I have enabled IGMP snooping.I've read that the Apple Bonjour service isnt designed to work on a multi subnet network - but both the Apple TV and iPad are connected on the same subnet. Sounds like some kind of timeout but not too sure.
we updated our NAC appliances from 4.8.1 to 4.9 and have noticed that web authentication is no longer woking on Apple IOS devices. We had setup a user page for the MAC_ALL OS and iphones etc. were able to authenticate using thier browser ok. Now (after the upgrade) after they authenticate they receive the below warning.
There doens't seem to be any other config changes we can make for the IOS device.
i'm already has one internet connection is conecting directily to the Core Switch 6509, and the Switch is route any internet request with default route:
SW6509-conf)# ip route 0.0.0.0 0.0.0.0 10.170.10.10
10.170.10.10 is --> Next hop for the DSL router internal IP, and it's working fine.
We have a new internet connection with another ISP/ with another DSL router, how to connect both of them to exit from the Core Switch 6509.
is it ok if i make another default route to the Next hop to the new DSL router as:
SW6509-conf)# ip route 0.0.0.0 0.0.0.0 10.80.10.10
10.80.10.10 is --> Next hop for the new DSL router internal IP.
I tried putting in for a Return # number for my modem but was told I can't get one even though its under warranty because I can't find the receipt.The modem LAN port 1 keeps dropping to 10mpbs instead of staying at 100. Is there anywhere I can get firmware 1.00.13 for this modem.
We installed a DIR-615 Vers. E1 FV. 5.00NA and since then i-Pods and i-Pads keep dropping wi-fi connections. All wireless PC's and printers are working fine. We have configured the wireless as:Mixed 802.11 n,g and b. Auto channel csan enabled, using channel 6. Wireless security is WPA-Personnal. WPA is configured as Auto, TKIP and AES with a pre-shared key.
We are using cisco 3502i AP's and 5508 controler. We have two SSID's. "SA Wireless" and "Guest Wireless". SA Wireless is WPA2 enterprise security and the "Guest Wireless" is open. The iPads will disconnect from "SA Wireless" and join "Guest Wireless" at random. Is there a way to force them to stay on "SA Wireless" and only change if you actually tell the iPad to change?
I have a small home network currently using a cisco 841 which is working great. Host a web site and Exchange plus all 10 computers access the net using Verizon FIOS all works. I can even VPN in to my newtwork remotely.I can only VPN using the Cisco client. I would like to use the Native Windows Client and Ipads and Iphones. I believe they use PPTP and the Cisco client is using IPSEC.Which Cisco router can I get that would support all the above?
I have a small home LAN of four hard-wired PCs and two iPads and two notebooks which are connected by wireless. At the heart of it all is a Linksys X3000 wireless router. Any of the four PCs that are hard wired to the X3000 have no problems talking to each other but none of the wireless-attached iPads or notebooks are able to see any other machine on the network. All machines are able to access the Internet.
I work at a small private school that is going to implement about 20 ipads for classes. Students bring their ipods and iphones and are connecting to the existing unsecured wireless access points and are taking up the remaining IP addresses in the DHCP scope. I am running out of IP addresses and was wondering if I could set up a VLAN using the Cisco WRVS4400N for all of these wireless devices the students will be using. I plan to pull out all unsecured wireless AP's and replace with what ever solution we come up with. I will need about 6 access points/routers to cover the entire school. There is not a lot of money for technology and the ipods were donated. I have never set up a VLAN before. Is there an inexpensive way to allow the students with their personal ipads/ipods and the 20 ipads owned by the school to connect to a VLAN to keep from using up our DHCP IP addresses from the server.
I have 2 Cisco Catalyst 6509 switches connected directly using direct point to point link.The OSPF is configured for point - point link.The currently the interface is down administratively.I will unshut the port . After that i would like to know how much time will it take for the ospf to establish the neighbour relation.
I currently have a couple of 6509 chassis (router/switches) with the following hardware blades:
x3 48 ports x1 NAM x2 Sup720 Running 12.2(18)SXF3
I am keeping the four Sup720 modules and have purchased new versions of the others blades including two new 6509-E chassis?Can I take my stand-by Sup720 out of the production machine and insert it into the new chassis?

Android users can connect to our hospital guest wireless but will not have connectivity. Our wireless infrastructure is WISM based with 2 controllers on 6509 platform. We have a mixed environment of 1231, 1252 & 3502 series APs.
Had issue connecting just Android devices? All other devices connect fine.
I need to have some (maybe four) virtual network interfaces, one face of them connected to my laptop and another face bridged to one of my physical network interfaces.How can i do that?Ive tried VirtNet and Microsoft Loopback Adapter but no success.
I will upgrade my Wireless Controller Firmware 7.2.103.0 But I dont know WCS will support manager new controller firmware 7.2.103.0 ?is need NCS to manager? or WCS can be manager new controller firmware 7.2.103.0 all feature?
Now My hw is
Csico 6509 Sup 720 3b 12(33)SXJ My Controller is WiSM2 WiSM2 is 7.0.116.0 WCS is 7.0.172.0
My AP get IP from 6509, but client cannot get dhcp from my dhcp pool for client, what is the reason?i have 3750g switch with integrated WLC, i connect it to 6509 I did all configs yesterday here is outputs
WLC Interface Name Port Vlan Id IP Address Type Ap Mgr Guest -------------------------------- ---- -------- --------------- ------- ------ ----- ap-manager LAG 10 172.16.10.100 Static Yes No globus LAG 20 172.16.20.254 Dynamic No No management LAG 10 172.16.10.99 Static No No service-port N/A N/A 0.0.0.0 Static No No
My company has been contracted to upgrade the 2 WiSM1 modules on a 6509 for a customer. The hardware isn't changing but the software is being upgraded to WiSM2. The cutsomer has HUNDREDS of AP's and dozens of VLANs and subnets (large municipality and school district).
Cisco SE's have been pushing the customer to purchase the WCS 7 software (they've been managing these Controllers independantly) stating there is no mechanism to upgrade WiSM1 configs to WiSM2. I am vaguely familiar with the cisco controllers but have little WiSM experience. So i feel like i'm working without a net here.
So,
1) Any way to migrate from 1 to 2 without the WCS and without having to reinvent the wheel?
2) How does the WCS make this transition easier? What does it do to the WiSM1 configs to make them WiSM2 compatable?
I am getting an alarm on WCS where a one controller is down, unreachable from WCS, while the other one is reachable on the same WiSM module. Upon investigation, Status of controller is shown as "Oper-Up" for all controllers on Supervisory engine. Hardware platform is Cisco 6509-E.
WLAN Slot Controller Service IP Management IP SW Version Status ----+-----------+----------------+----------------+-----------+--------------- 2 1 192.167.10.11 172.19.47.65 6.0.196.0 Oper-Up 2 2 192.167.10.12 172.19.47.66 6.0.196.0 Oper-Up
However, I can not ping the managment interface of the down controller while the other controller management interface is pingable. All these interfaces are in the same VLAN.
ping 172.19.47.65 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.19.47.65, timeout is 2 seconds: ..... Success rate is 0 percent (0/5)
Problem is fixed when I reboot the problematic Controller. However, this problem re-appears after some time. I am not able to figure out why controller is not able to ping its default-gateway which is an SVI interface on Supervisory card on the same chassis, and showing status UP/UP. Is it a software bug or backplane fault or any other reason ?
We have a WISM in a 6509. The 6509 lost power (the UPS failed) and upon reboot the WISM isn't allowing AP's to connect. The WISM is blade 4. Upon consoling in, I get this error message for all 8 ports: 42w6d: %EC-SP-5-CANNOT_BUNDLE2: Gi4/1 is not compatible with Po407 and will be suspended (trunk mode of Gi4/1 is dynamic, Po407 is trunk)
I have inherited a 6509 VSS switch system as the network core and have the task of ensuring proper redundancy and redesign of the directly connected data center devices. One of the connected devices (WLC 4402) physically appears to be connected to both switches - the WLC is in the same rack as VSS-Chassis1 so I can trace the fiber from WLC port 1 to gi1/1/22, the other fiber from the WLC port 2 goes into the floor and presumably over to VSS-Chassis2 gi2/1/22 (there is fiber connected there, I have link lights on both sides, and the port channel, Po200, on the VSS switch which is configured on gi1/1/22 is also configured on gi2/1/22). My question pertains to the CDP neighbor output I get on the VSS switch: (truncated to include just the WLC) [code]
So my question, arising at least partly from the apparently misleading CDP information, is this: How can I confirm that the WLC is correctly dual homed to both core switches? (short of tracing the cable) I ask because there are several other devices (not WLCs) that need to have the dual homed connections confirmed.I tried a layer 2 trace route but for all macs associated with the WLC, the trace abborts with the error "Device has Multiple CDP neighbours on destination port."
We have a mix of 1231 and 1242 access points in an LWAPP environment. They are connected to WiSM controllers in our 6509's and are managed by a central WLC. Everything is running version 7.0.230. My question is can I apply MAC address filtering on a select group of AP's to restrict access to a specific SSID broadcast on these AP's without affecting other AP's also connected to the same WiSM?
