Cisco :: User Connects To Weaker 1252 AP?
Mar 25, 2013
I have Cisco 1252 APs in my network and also a WLC with software 7.0.98.0 and a WCS system. In certain areas I have an SSID with 2 or more APs configured as part of the group. Some users are connecting to the SSID on the weaker AP when there is a much stronger signal available from a different AP.I have looked into this issue before and have been told it's a porblem with the client's Wireless NIC or the drivers. The issue is I'm using the most updates drivers on some users and it makes no difference. Although it may be a problem with my clients I need to fix this on Cisco's AP side. What are my options? I believe MAC filtering is only per SSID so that would defeat the purpose, can I filter by specific AP and still allow the user to connect to the SSID? Or should I seperate the APs from the 1 SSID and create multiple SSIDs so the user can select the stronger network?

We are using an ASA 5510 and remote access (SSL VPN) using the AnyConnect client.
Is it possible to display a user message when a user connects using the AnyConnect client, matching a specific dynamic access policy? Can the message be displayed when the action is "Continue" rather than "Terminate"? I can't seem to get this to work and wondered if there was a LUA function to do this.
We have a DAP which gives a restricted ACL when the user's anti-virus is out of date, and I wanted to notify the user to update their anti-virus and reconnect.

I have a Cisco ASA 5505 with eth0/0 as outside and eth0/1-eth0/7 as inside.On the outside interface I have to IPS's. One cable and one dsl.My main connection goes out over my cable ISP.I have 2 static routes on the outside interface.One with metric 128 for my cable ISP.One with metric 254 for my dsl IPS.I'm tracking my cable ISP with a ping to their default gateway (only available on my cable ISP)Failover from cable to dsl works perfect when my cable IPS goes down and fails back when it's back online.My problem however is when a VPN user connects from the outside using the Any connect client.Every time, about 5-10 minutes later, my tracked route get's removed (message: 622001) and added back 15-30 seconds later.This of course drops the VPN user. It doesn't happen again if the VPN user logs back in after that. [Code]

Just got the E4200 and it seemed great at first. Connected at 450mbps at close range (maybe 6ft away) and got 223mbps transfer.It seems that recently my signal is much weaker. I'm around 6-8ft away from the router and I'm getting between 270-360mbps, which to me is poor given the short range.
InSSIDer says the RSSI is -50, while my other wireless N router (dual band) is -35 and is in the exact same location. I'm using the 5ghz radio only, and it is set to N, and I'm using channels 44 and 48. I checked the hidden advanced wireless page and transmit power is already set to high.
My laptop has an Intel 6300 wireless card.I'm using the current firmware 1.0.02. I've noticed that the speed of the router randomly seems to drop off too (just as I type this, the link rate has gone back up to 450mbps... typical). Is the router throttling when it gets hot or something? So I just want to find out if others are experiencing similar rates at the same kind of distance. Seriously, how can you advertise something as 450mbps when you can't even get that link rate at a distance as short as 6ft?
I can't see any thing I can do to increase the link speed (back down to 270mbps now), short of a firmware update to increase the power and use higher channels. I hear the higher channels are much better, so who do I have to write to, to plead for new firmware?This is a great product, but it's totally ruined by stupid internal antennas and a weak transmit power. Maybe if we make a noise about the not so maximum performance, they might address it.

I recently bought the top end ea4500 hoping its "high end" claims would get a better wifi signal in my bedroom(on my iphone 4s) than what i was getting with my WRT54G.The end result is it constantly drops signal completely or shows my network but when I try to connect says "cannot connect to wireless network" even though it's staring me right in the face. When I hook my WRT54G up, I get a signal.. all be it weak, but at least it doesn't drop out on me.Did I just waste almost $200 on a high end router that can't push a signal out stronger than my almost 7 year old WRT54G? or am i missing some setting that will make this EA4500 worth its claims? settings info:everything is pretty much on "default" aside from the SSIDs for the different bands and the corresponding WPA passwords.
also another problem, it seems like the router itself craps out every 60-120 minutes, no leds lit up on the router and my modem (Cisco DCP3010) shows no "link". Yet when hooked directly to the PC there is a "link", so pretty sure its the router and not the modem.

I'm having an issue with a 1252 LAP that is connected to the WLC over a WAN link.Basically, it won't associate. The following is taken from a console into the LAP:
*Mar 1 00:00:07.799: %LINK-3-UPDOWN: Interface GigabitEthernet0, changed state to up
*Mar 1 00:00:08.799: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0, changed state to up
*Mar 1 00:00:26.851: %LWAPP-5-CHANGED: LWAPP changed state to DISCOVERY
*Mar 1 00:00:27.003: Logging LWAPP message to 255.255.255.255.
[code].....
The ap-manager interface is configured correctly and there isn't a duplicate IP address. The LAP was initially stand alone and was converted to LWAPP.The MTU over the WAN link is 1500 bytes.All I'm getting from the WLC debugs is:
Mon Jul 20 11:42:59 2009: 00:22:xx:xx:xx:xx Received LWAPP DISCOVERY REQUEST from AP 00:22:xx:xx:xx:xx to 00:19:xx:xx:xx:xx on port '29'
Mon Jul 20 11:42:59 2009: 00:22:xx:xx:xx:xx LWAPP Discovery Request AP Software Version: 0x3003300
Mon Jul 20 11:42:59 2009: 00:22:xx:xx:xx:xx Successful transmission of LWAPP Discovery Response to AP 00:22:xx:xx:xx:xx on port 29
So basically the join messages don't seem to reach the WLC. In fact they don't even seem to reach the local router on the remote subnet. The discovery packets are seen on the local router but the joins don't seem to appear at all.I'm not sure if it's a latency issue. Average latency over the WAN link is under 70ms.I'm assuming the certificate on the WAP is MIC and the MAC details have been entered into the WLC AP Security policies for authentication. I'm not seeing any debugging messages relating to bad authentication at all.I can't debug from the LAP as it's LWAPP, obviously.We're running WLC version 4.2.130.0.

it is possible to wide the range of powerconsumtion on this switch from 15.4W up to 20W? We will rollout some accesspoints with 2 radiomodules on CISCO AP1252, but the Powerconsumtion of this AP then ist 18.5W. The max allowed from firmware is 15.4W like 802.11n-standard.

Okay, I'm working on a project and the company I work for wants to add 5 Ghz antenna's to their Aironet 1252's. Okay not a problem, except I've never worked with these routers before and I can't get the configuration set (). Once I get 'em on one I can get them all done.

I have two cisco airenet 1252 autonamous access point that are configured as point to point bridge. Now I want to confiure AES encryption or WPA2 using a pre-shared key however I do not see the option to do this . The only option I see under ciphers are:
wep 128
wep 40
TKIP
[Code].....
Is it possible to use either AES or WPA2 using a pre-shared key on the 1252 autonamous access point? preferably using the web interface.

I am replacing an older AP with a new 1252 unit. I attached everything and powered it up, but my DHCP server does not appear to be finding it and assigning an IP address. The status light stays green and the ethernet light blinks randomly green. Seems to be connected fine, but without an IP I cannot configure it to use it.

I have a lightweight AP that boots into RoMmon, if i hold the reset button in for 10 seconds or so it will boot into the IOS and download the config from the controller but never registers. then once i reboot it it goes back to Romon unless i hold in the button again.

an Aironet 1252 which is failing on boot. When power on the access-point shows the error below.
WARNING: A memory error occurred during the system start-up self-test. The device must be serviced if the error persists.
The following commands can, optionally, be used to initialize the flash file system and the TFTP file transfer system:
But when this happen, I can start the IOS manually doing flash_init and boot in ROMMON. After do this commands, the access-point starts and works normally.
How can I check and correct the memory and solve this issue?

we want to have full wireless coverage in a big warehouse (120mx90m) and 15 meter Height that will be having big racks (14 meters height) and 2 meter between the racks and the rack itself is 1.5 meter (2 rack back to back), now we will be having scanners and we need to make sure the wireless is covering everywhere.Where is the best place to put the AP, Ceiling? How Many APs per row ? each row will be around 60 meters length.
Is AP 1252 a good choice? The scanners are a/b/g.What i'm thinking of is to put 1 AP per row mounted on the ceiling and antennas facing down because it is hard to mount the APs between the rack because of the automated racking system.

Currently my company has 1 primary SSID that is used throughout both floors of the building. We have 1252 LAPs which have 2.4 and 5Ghz antennas. I'm not sure if this issue is only with XP or perhaps it's the computer's drivers but we run into problems with end users going to a different location and having a very weak signal or nothing at all, yet coverage is fine. I believe the problem is the end user's machine selecting the strongest signal and it I have the feeling that switching bands isn't being done as it should when it's in range. So my question,
Should I split up our 1 SSID and created multiple SSIDs according to the location and include 5Ghz or 2.4Ghz in the SSID name so it's easier to ensure that users are connected to the proper signal? I want to ask if multiple SSIDs would still enable users to freely roam (as long as the ssids are configured) throughout the building without noticing a loss of signal but currently just having 1 SSID isn't really enabling people to freely roam around without connection issues.I don't believe having multiple SSIDs will be useful for the computer's choose their connection any more efficiently but allowing the user to manually see what they're connected to and pick something better according to their location.

I am configuring a mobile van that is used for a mobile health clinic to drive to several locations and when pulling into an allocated parking spot the van will connect via wireless automatically. I am using autonomous 1252 AP's and am considering either briding or workgroup bridging.
The issue I am encountering is that the AP inside a van is a router that has to do DHCP across the wireless and because the ethernet interface between router and AP in the van never goes down the router does not know to re-DHCP. I remember from way back there was an IOS command to track a serial interface and drop the ethernet if the serial link goes down. Is there an equivalent command for AP's to drop the ethernet interface if the radio interfaces go down?

I would like to add an additional antenna to a 1252 LAP but I'm unsure of a few things...
I know this LAP currently has at least a yogi directional antenna (AIR-ANT2410Y-R) and also a ( AIR-ANT2485P-R) connected to it. The access point is in a ceiling so I cannot view the connections but according to this data sheet, { URL } each of the antennas I've specified require 3 per AP. I am only aware of 1 of each being used so not sure why 3 would be required?
Also on my 1252 1 side has 3, 2.4Ghz connections for antennas, TX, TX&RX, and RX. If I want to only use 1 AIR-ANT2410Y-R, would this be connected to the TX&RX port? Do all antennas support transmit and receive or are there some that only support TX and others that only support RX or is this based only how you configure the antennas? On the other side of the access point there are 3, 5Ghz antenna connections.

I found a few older forum posts and documents online discussing how to create multiple SSIDs on 1 1252 AP using the WLC and they state that VLANs are needed for the interface and then I've read that multiple SSIDs on 1 interface are also possible. I'm not sure on how to actually configure this. I would like my 2.4Ghz radio on the 1252 to be associated with the current SSID in production and the 5Ghz band associated with another SSID that's in production. I couldn't find an option in the WLC or anything stated in the documents I've read about how to associate the radio band with the SSID.

We are using WiSM WLCs and WCS to control a variety of 1131,1142 and 1252 APs utilising AP groups.
I've noticed on WCS that the power of certain APs is at a low setting, even though the APs surrounding them are also at a low setting. This is causing some gaps to appear on the heatmaps. I was under the impression that the WLCs would regulate the AP power to compensate for any gaps. Currently the global TX power level assignment method algorithm is set to automatic every 600 sec.
Now, obviously I could change this to fixed (not ideal as I may not want all my APs to run at max power all the time) or to on demand (also not ideal due to the increased admin).
Is there a way I can verify that the automatic power levels are adjusting as they should? Why are there gaps appearing in my heatmaps?
*NB It's not just the gaps on the heatmaps, I'm getting reports of dropping wireless signals from users hence me looking at the heatmaps and they just happen to correspond.
WLC version 6.0.199.4
WCS version 7.0.172.0

I have two 1252ag wireless access points running in lightweight mode, and connected to a 2006 wlc. They were both running fine until this morning. One of the 1252s won't stop rebooting itself. I consoled in, and this was the output -

I have two 1252s on ports 1 and 2 off a Catalyst 3550. No other device on the switch except the fiber uplink.
Initially 1252 #2 (on port 2) resets for no reason at no specific time. We did not have a problem with 1252 #1.
The show ver on #2 does indicate that equipment resets due to power. I figured the 3550 is having problems powering two 1252s so had this AP on PWRINJ4 (validated its not drawing power via show power inline).
Today, #2 does not reset. However, now #1, which is the only device using inline power is now resetting. Same thing, reset due to power. Same weird behavior, at no particular time.
I've also have "no cdp enable" out off each port as i understand CDP sometime cause device to not boot up (15w versus 15.4w issue).
Both AP btw are Standalone IOS.
