Cisco Wireless :: 1200 General Approach To Troubleshooting Wi-Fi Disconnects
Sep 28, 2010
For years I have received occasional complaints about users being dropped from WiF and then reconnecting like a minute or two later. I wondered what tools people on the Forum used to troubleshoot this transient problem. Cisco APs like the 1200 don't seem to inform about why someone left. One thing that has been very useful over time is using Network Sumbler to see what WAPs are in a vicinity and make sure there is not channel overlap. How to troubleshoot transient wireless network drops?
I have a node with one physical wireless interface and I need it to offer AP service to other nodes, connect to an existed AP, and connect to other nodes in ad hoc mode. If I create 3 logical wireless interfaces of that interface and configure each one respectively to the modes above, would this work? do they use the same MAC address or each needs to be configured a different one?
We have 2 Cisco 4400 series WLC and a whole bunch of 1231G APs connected to it.Sometimes the wireless network get really, really slow.Does Cisco have any built in tools for troubleshooting bandwidth or sluggishness issues?And how does one go ahead and troubleshoot something like that?
I have linksys E4500 and I would like to be able to see the website visited vs ip address.Is there a way to enable same or achive same via parental controls.Again I do not want to block a website but monitor which websites are visited. Is this achievable via router or an additional software/hardware required to be used with router
I am working with a client who is adamant their backbone is fine. However, I am unable to get a single iperf connection to generate anything more than 9.5 megabit/s, and can go all the way up to 322 megabit/s with multiple streams before it looks like we are saturated. Note the example below for a single stream has a 1MByte window, with 8kb we were only able to see 2.4 mbits/sec per stream (as seen in the per stream in the example below). Where would you begin to look for why we cant seem to exceed 2.3mbit/s with an 8kb window, or 7.88 with a 1mbyte.
I have an authorization rule which verify that the AV (mcafee 12.x) is installed (NAC agent), time restriction and so, and so....The connection failed with this code :
15039 Rejected per authorization profile.
How can I obtain a some more details on that ?I mean, I'd like to know which condition is not verified and lead to a failed connection.
I'm replacing a PA-POS-OC3-SM with PA-POS-1OC3 in a flex Wan module (WS-X6582-2PA) in Cisco 6506 using WS-SUP32P-GE PISA.I have a hard time bringing the "protocol up. the status I see is line up and protocol down. Debug shows (attached) no comunication with the edge router but when i put the older PA (PA-POS-OC3-SM ) back evertything works fine and older PA has been running for many years without the issue. I'm replacing older PA is becuase this is going EOL. I had opened a TAC case but the TAC engineer added no value. [code]
I have a ACE4710 setup to load balance a couple of web servers. The real servers all show as inservice as do the propbes and serverfarms/virtual servers. If I ping the Virtuual server ip address I get a reply but it I try to access VIP via telnet or web browser. I get a connection could not be open error on the client.The question is how do i determine where the error is comming from so far I can not tell if the client is getting through the acl or not.I have used the trouble shooting guide and nothing has worked to determine the cause so far. show service-policy int479 detail does not show an increase in the hit count when I try to connect.show stats conn does not show an increase in failed or timed out connections when i try to connect. [code]
I had unplugged my computer due to painting the room. When i plugged back it I couldn not connect to internet. But oddlly enough my mcafee security center gave me a message that mcafee subscription expired, which it can't as I use it through my subscription through aol. Had this problem once before. So i uninstalled mcafee. I ran malwarebytes to see if there was anything that might prevent me for accessing internet, it found two adware that I quarentined.
I have tested my ethernet cord and connectivity on another computer it works fine.I had a realek RTL8139 Family PCI Ethernet NIC, i reloaded the driver after downloading from my other computer, now it say it is a realtek RTL 8139/810x family ethernet nic, not sure if I downloaded the wrong driver but before that I tried changing the speed to less than auto detect.
I have rebooted in safe mode in case there was a virus. I am at my wits end.Is there a way to factory reset the network adapter. What else can I do. light at the ethernet port looks to be yellow. Everything says it is working, I just can't connect.
We have a 1200 Aironet just go down hard for no reason through out the day, we replaced the Power Injector with a C2960 POE Switch, we also replaced the cabiling. When it goes down hard all three lights are still green as if the AP is still up. We verified the IOS with other stores and everything is the same on the configurations, versions, and IOS.
I got my final assignment from school, and my teacher asked me to configure 2 Access Points (1200 series) directly on a Wireless Controler (Cisco 2106). I can't ask my teacher for any questions, cause he doesn't know how to configure it also, THAT's why he's asking me to do it.I've learned a lot of things about the default static interfaces (the "management" and "ap_manager" interface), but i can't seem to fully understand how to configure it.I want to use the Internal DHCP server of the WLC. How I can get those 2 Access Points working on the WLC. I only seem to get DHCP issues.
This is what i've done:
- Leave the configuration of the "management" and the "ap_manager" default (172.16.1.30 and 172.16.1.30). Bound to port 1
- Made a new interface "AP1" with IP-Address 10.0.0.10 (/24), default gateway 10.0.0.1. Primary DHCP server: 172.167.1.30
- Made a new interface "AP2" with IP-Address 192.168.1.10 (/24), default gateway 192.168.1.1. Primary DHCP server: 172.167.1.30
- Made 2 DHCP scopes within the 192.168.1.0 and 10.0.0.0 networks.
For some reason, when i boot up both AP's, the won't get any DHCP address.
I am looking at deploying a Cisco Virtual Wireless LAN Controller (vWLC 7.3).Do I need Prime Infrastructure to manage the environment, or can I manage my AP's (1200 series) using the vWLC alone?
I want to disable the MAC authentication that is configured in my Aironet 1200 Cisco Access Point, now set to "Local list only". I want that any wireless device can connect if the user knows the wep password.
I cannot find the option to disable the MAC authentication.
I am using 5 Cisco 1200 Series APs with both an A and G radio. Is there a benefit/problem to running both simultaneously? I would have one SSID and is setup for Fast Roaming as well.
For the past week, I've been looking to implement wireless technology at our educational site. We've conducted some tests with an AP1200 and we were satisfied with the performances of 802.11a standards.
Since one of our requirements is bandwidth, we are looking to implement a 802.11g standard for that need. Unfortunately, Cisco does not offer any client access adapter for that 11g standard as opposed of the competition. What kind of client adapter (PCMCIA) can Cisco recommend to work with AP1200 under the 802.11g ?
I have 2 Cisco 1200 G AP's connecting 2 different locations. Location A ( La ) I have a RVO82 router connected to a 50Mbit cable connection. I have an AP setup there using a 1 Watt booster and a 24db wire grid directional antenna. Only one antenna here, the other disabled.
At Location B (Lb ), about 1.5 miles away, with good to excellent line of site, i have the other setup as a WGB with a 15db wire grid directional antenna with a 1 Watt booster. Also only one antenna here, the other disabled.
WGB feeds a simple 8 port switch and in that switch i have a simple belkin wireless router setup as an AP for Lb's wireless access,
The signal strenght between the two locations is -49 to -52 db, depending on what time of day I check it.
I have had this setup for a couple of years now. I recently switched from a 3Mbit DSL connection to the 50Mbit cable connection hoping to increase my bandwidth with no luck. . When I first set this up i had a 6Mbit cable connection and it maxxed out at 5 Mbit at Lb. I thought i would be able to add more boosters and antennas as time went on to go from half duplex to full duplex (the way i think of it is one antenna receiving and the other sending, at both locations) so that when our ISP had faster rates available, i could upgrade. I recently read somewhere on the net that it is not possible to run full duplex in the AP to WGB setup i have. Is that true?
My main concern is increasing bandwidth on the WGB side Lb. When i upgraded to 50Mbit, i still only max out at 5mbit at Lb. Before i thought it was due to not being full duplex or weaker signal strengths (I've always had the 1watt booster at Lb, then i added one later to La with no benefit noticed except signal strength is better and uploads seem faster from Lb....)
I have a situation, where I dont need email and where is no SMTP server in this network, but I need CCO-access for EoX/PSIRT from LMS. Because both settings are in the same menu and LMS4.0.1 does real TCP:25 checking for given SMTP-server before can apply, I cant save my CCO-credentials. What can I do?
I have two different LAP 1300 and 1200 in my network and I need to add theme to the WLC,I successes to add one of theme by the option 60 in the DHCP pool at the Core SW,How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?
Is there any detailed documentation on the Site Survey Client mode on the AP 1200?When using this mode I cannot see any indication that it has associated withthe root AP. I would like to be able to pass traffic from the ethernet port to the root AP VIA the AP in client mode. The Ap in client mode shows the radio in blocking when in client mode, is this normal? Is there a way to manually change this to forwarding mode?
I've got an iPad2, which works without issue at home (1130 AP/ASA5505), but at my office, we have a 1200 series AP. It's hit and miss, but other people who bring iPads in have noticed the same issue--our internal SSID is non-broadcast. Even though the SSID is previously configured and works on occassion, there are times where it won't even see the SSID at all to connect.
This happens with iPad and iPad2, iOS4 and iOS5...
LIke i said, works fine on my non-broadcast SSID at my home on an 1130 AP...
Is there a way to configure client/user to AP authentication without using encryption for joining to an wireless network? What we need to do here is protect network access at our hotspots by enforcing a password to get connected. The other part is making it compatible with every possible device so we need to have encryption off. We have a mixed environment at this time until everything is upgraded. Aironet 1200 series and some new Aironet 1142 models. No controller, all standand alone AP's
I have a WLAN with 5 1200 Series AP (A/G) configured for Fast Roaming using the Cisco supplied documentation. Can I use one user name for all of my devices to connect to the Internal Radius Server? This would be similar to having a passphrase for WPA.
I would like to be able to have a few "guest" users on the Wireless network for visitors. Is there any method to have a prompt for "Username / password"? I would like the user accounts to have different expiry periods if this is possible. My current config is attached. The SSID "test" appears on the network. The SSID "test111" does not appear.
I have a office network that was setup before I started. We have a 172. subnet and a 10.2 subnet. When users on Wifi get a 10.2 address ( ran out of 172 address ) they are not able to get out to the internet. But if the laptop is connected to a LAN port and get a 10.2 address they are able to get to the Internet. Not sure if its the Aps I need to configure or the Pix seeing that if they get a LAN address of 10.2 everything works. This is becoming a bigger issue now that the company has out grown its main subnet (172.)
APs= AIR-AP1231G-A-K9 Vlan = 172.16.1.XXX Vlan2= 10.2.0.XXX Hardware: PIX-515E, 64 MB RAM, CPU Pentium II 433 MHz
We had two dozen Aironet 1200 access points and a controller donated to us from a local hospital that no longer needed them. My boss would like me to set one up with 3 VLANs:
- encrypted VLAN for staff
- encrypted VLAN for students
- unencrypted VLAN for guests
Ultimately, we'd like the staff VLAN to have access to all internal network resources, the student VLAN to have access to several pre-defined printers, and the guest VLAN is web-only access. Whether the controller we were given will accommodate that, we won't know until we get one Aironet 1200 programmed and connected to the controller. For the time being, I just want to get this access point programmed with the 3 VLANs.
I'm easily able to get it running a single SSID (non-VLAN) network and confirm that I can use that network fine. However, I need to set up these 3 VLANs. I can connect to it via telnet if that'll let me program it faster.
I am running the upgrade tool on Aironet AP1230B-A-K9. I can't join the controller by using the upgrade tool. the error is "AP does not have Supported Radio". What radio is the upgrade tool or controller look for on Aironet 1200 series? This AP is running 802.11b. However, I have several APs which the same model is running on the same one controller. The controller is model 4402.
Is it possible to setup a Cisco 1200 AP with 802.1x to drop users into the corprate network if they have a certificate or if not to put them on the guest network?
I recently purchased a Ciso 1200 Series WAP and I want to bridge this to my existing Cisco Wireless Router So I can extend my coverage. I have done some research but keep coming up short as to where I need to start. Note*(I do not want a physical connection to the WAP, I simply want to be able to bridge the connection from my existing Wireless router to my WAP.
I have some aironet 1200 AP's. I want to use this with a windows 2008 radius server. I followed the guide on [URL]. Unfortunately I can not get this working. In the securtiy log of the event viewer there is always the message "authenication was not succesful because an unknown username or incorrect password".
- Is it possible to get this working?
- If yes, is there a manual how to configure the AP's and the radius server, or are there any hints?
- Is this the best way to setup a wireless network or is there a better way?
I saw there is also a local radius server inside the 1200. Can all the 1200's work together? I suppose that if I use the built-in radius server than I can't make a connection to my AD database, correct?
