Cisco Wireless :: Configure 802.11n On WLC4404 Or WLC5508 In 2.4Ghz?
Aug 15, 2012
how to set up support 802.11n on WLC4404 or WLC5508 in the 2.4Ghz? WLC4404 supports 802.11n? or support this protocol only in the brochures? I spent a few days, but did not get the result. I'm connected at speeds 65/130Mbit, but the real speed tests never exceeded 45Mbit. The AP from the test laptop is 7-10 meters.I tested the laptops with a Linksys AP E1200-EE ( 40Mhz, FastEthernet uplink port...)and received nearly 100Mbit!
At WLC5508 able to connect at speeds 150/300Mbit/c but only in the 5GHz band, but real speed tests never exceeded 70Mbit.In 2.4Ghz range I connected at speeds of 130/144Mbit/c, but actual measurements showed no more than the 45Mbit.
All tested with iperf and with site speedtest.net.
iperf -w64K -s
iperf -w64K -i 2 -t 300 -c x.x.x.x
Laptops: Asus (Atheros AR9002WB-1NG) and Sony (Advanced-N 6230).
My tests AP: 3501I-E and 1252AG-A
SW on WLC5508 22.214.171.124
AP tested in different variants - open system and WPA2+AES.
how to migrate from WLC4404 to WLC5508. I want to know your propositions.
I could replicate the configuration manually but there is a lot of confirugation menus and all. If both could be online and migrate the AP to the new one until there is none on the old one, it would be great.
i have 2x WLC4404 they are in the same mobilitygroup and worked since a long time. Three days ago, ill upgraded one of them from 126.96.36.199 to 188.8.131.52. I have nearly 90 APs (1231,1242, different models)
The upgrade was successfull and i moved the APs from WLCA (184.108.40.206) to WLCB (220.127.116.11) almost all APs worked fine without 6 of them. This 6 APs cannot ping the AP-Manager-Interface from WLCB. But they can Ping the Router in this vlan, WLCA-AP-Manager and all APs in this subnet. They only cant get to the AP-Manager-interface from WLCB. Ping to Managementinterface of WLCB is also ok. Management and AP Manager are in different subnets. All APs and the AP-Manager-Interfaces from WLCA+WLCB are in the same subnet.
Switchportconfig and routing are ok. ive resetet the APs to default, checked switchport config, resetet switchport, power down ap for a while. ive tried many things, but nothing worked.I ever only can ping AP-Manager from WLCA, but not WLCB (again same subnet, and about 80 other APs work fine) If i install a new AP on the same switchport, it works fine, without any issues. when i than unplug the "newAP" from this switchport and again connect the "oldAP" it can ping WLCA+WLCB and anything is fine.
Now i have the next and bigger problem nearly 15 of the APs that worked fine after upgrading, for now 3days+. Now they cannot ping the WLCB-AP-Manager-int too. And they dont failover to the WLCA with (18.104.22.168), i can reboot but they ever try to connect to WLCB. But they know both controllers.I only can get them to WLCA via ssh: capwap ap primary-base WLCAsname WLCAsmanagementIP..why the APs dont fail over if they dont reach WLCBsAP-Managerinterface?why i cannot ping WLCBs AP-Mana-Int from some APs.
We currently have about 50 Cisco 1252 wireless access points running from a 4404 Wireless LAN controller. We need to order more APs, but of course the 1252s have been discontinued.Was assured by Cisco that the 1262 would work just fine with our WLC. I'm messing around with a trial 1262 and am running into problems.We hard-code the IP address, hostname, default gateway, and controller IP address in each of our access points. I did that with the new 1262 the same way I did with the 1252s:lwapp ap ip address lwapp ap ip default-gateway etc., etc.That didn't work. Then I tried doing the same thing using (not sure if this is the correct terminology...) the capwap commands.
The AP still doesn't show up on the WLC's GUI, though I can ping the AP from the WLC and I can ping the WLC from the AP.I also can't use a web browser to get into the access point's configuration tool. Do I understand correctly that the lightweight APs don't have the GUI?
How to disable dhcp proxy on controller and what is the impact of doing it in the middle? We tried once by giving 'config dhcp proxy disable' command but seeing virtual ip again.(likely it gets back to proxy mode). We also have ip helper address on the L3 interface. We have only external dhcp servers configured..
I have 2 controllers as below one with 6.0 version and other with 5.2 version AIR-WLC4404-100-K9 22.214.171.124 AIR-WLC4402-12-K9 126.96.36.199 GUEST..Control path between controller flaps.All mobility anchors on wlan index 7 are down.All mobility anchors on wlan index 3 are down.Control path to mobility member x.x.x.x is down.No problem observed when i have software 188.8.131.52 on both the controller.
We have two Cisco Wireless Controller 4404 with the IOS Version 184.108.40.206 and a lot of access points (ca. 170). Now i wan't to reboot a group of Access points where i found over a filter..Or how can i reboot all the Access Points at the same time over the Controller Interface? Is it possible? I only found the option in the WebGui where i can reboot 1 Access Point at the same time with "hardware reset".
We have a WLC 4404 with about 85 1121 and 1241 APs. - I just added 6 new 3501E with Antennas, and configured the a new SSID, but non of my clients can connect to any of the 3501s. One solution from a tech was to update the NIC drivers. I verified that all test clients are 802.11N and sometimes they find the 3501 but often they switch to another of the older and weaker 1121 or 1241s. On one test I had a 3501 just outside his room and his client nic was picking up a weak signal 2 floors up, then it would go to one 1 floor down. eventually we could get it to feed of the nearest 3501 but it would go back to another 1121 or 1241 soon thereafter,.
Can i run both 2.4 and 5ghz at the same time? so my N user's can connect at 300Mpbs on the 5ghz bonded, and my G users can connect to 54Mbps?Also i ask because of coverage, my 5ghz does not cover as far as the 2.4 so those at the extremity's could at least get G with a good signal?
Continuous dropping out some of them Access Points registered on the Primary Controller . What is the reason for this. We have a problem the last 2 weeks. What are the causes of falling out controler Access Points. The problem does not appear from logs. 70 LWAPs registered over Primary Controller. All AP mode is Local.
We ordered 2 Cisco AIR-LAP1242AG-E-K9 Wireless Access Points with 4 AIR-ANT5135D-R antennas.We accidentally ordered the 5GHz antennas instead of the 2.4GHz antennas.Would it be possible to use the 5GHz antennas as 2.4GHz antennas?If so, are there any down sides to it?
We have a small ofice in the 3rd floor of a building and we are using 2 access points Aironet 1130 URL
Since some time now the space has become really crowded with access points. 1 AP is on channel 5 and is almost unusable. The 2nd one on channel 11 has some APs to fight with and with smaller signall strenght.
I have been researching and read a bit about changing some access point parameters (RTS/CTS/timers) on a multi access point environment. I want to do that while waiting for 5GHz AP's (and because not all clients support 5GHz).
I purchased a EA4500 and at first I could connect to it through its default ciscoxxxxx ssid on my laptop which is 2.4GHz only. I upgraded the firmware using the PC utility and now I can't find the 2.4GHz SSID no matter what settings I do. I've disabled and enabled it multiple times, changed it to have no security or with security and enabled and disabled it and renabled it. Nothing seems to work, but for some reason the 5GHz side I can connect to using a 5GHz device. I've also tried disabling the 5GHz side, but still no 2.4GHz.
Decided to go with the e4200v2. 199.99 for a router 450 + 450 with a little extra features. very pricey but thought it would be worth it. I got it hooked up with no problems for the first 5 minutes. I have 35mbps down wired from the router and on the 2.4 and 5.0 ghz band about 25 feet from the router was getting just that!! no loss really. However after a few more speed test i noticed it was fluctuating very slow to fast. Also the 2.4ghz was only 144mbps. after getting in the router i changed the 2.4ghz to channel 6 and 5ghz to 153 and changed to 20mhz only on the 2.4 and 40mhz only on the 5.0ghz. Now all is doing well .
1. why am i not able to run the 2.4ghz on 40mhz? when set to auto i have a lot slower speed tests even know it is running on 20mhz only because I'm only getting 144mbps. I don't know why its not running 40mhz ? i don't know why i have to change it to 20mhz only why cant i leave it on auto and if i had a day with little interference it would switch to 40? when left on auto the speeds go down drastically
2. i notice that some channels are brutally slow on both bands. like 1.5mbps ? is this normal
3. is this even worth it if the 2.4 band is acting this way?
4. from insider i see that 5.0ghz only connects to two channels isn't suppose to be 3?
My 2.4 GHz is not working corrently on my EA3500 router. I have no trouble with my 5 GHz which I am currently on. On my iPhone I have to manually click the network even though it is known and then the wifi icon lights up full then goes dim then just flashes til it gives up. If I try connecting with my computer it just doesn't load the internet.
Currently we have 20 remote sites, each with 2-5 AP's each. They all connect back to our Main Data Site in the US and register on a single WLC5508.
We do not have a backup WLC, but are looking to purchase one. What I would like to know is, are there any problems with the secondary WLC being installed in our Main Data Site in Europe? These two main sites are connected via a 10M MPLS WAN.
So all the remote sites could still connect to the WLC in the US, but in the event of a WLC failure in the US, they would need to fail over to the site in Europe
I'm using WLC5508 /w 7.0..My client do not get its IP. Status shown "DHCP_REQD".I found in (Cisco Live) Troubleshooting Wireless LANs with Centralized Controllers This related with Enable/Disable DHCP Proxy checkbox. I solved. with Enabling this.But,
1) Why this box have been working correctly for longtime? No one did diable/enable this feature on my box.
2) I guest, ver7.0 Disables this chechbox by default. Or not? I also have others two 7.2 boxes. Those are all Enabled.
I'm working in a campus environment that has an existing wireless network using a Cisco AIR-WLC2112-K9 controller.There are 8 AIR-LAP1242G-A-K9 access points connected to the controller. Each access point has a 5.0GHZ 4.5dbi Cisco omnidirectional antenna, although the AP only supports 2.4GHZ.
Q1. Why a 5.0ghz antenna might had been used with a 2.4ghz AP, and if we can expect increased performance if we replace the antennas with 2.4ghz ones?
Q2. On the controller, the antenna gain is set to 0 for each AP. Is there also a benefit to leaving that 0 as opposed to 9 for 4.5dbi?
I purchased a e4200 in hopes that its dual band capability would allow us to run a 2.4ghz network for certain devices and a 5ghz for everyone else. I am able to setup the router and connect but it seems when the 2.4ghz network drops the router drops all connections.
At first I had the networks setup with the same ssid, then changed the 5ghz network to a new ssid but was still losing connection when the 2.4ghz network dropped. This may be a simple routing issue i am overlooking (bit of a network newbie).
On my new E4200, I cannot connect wirelessly to the 2.4GHZ band. I can only connect to the 5GHZ band. I know its not the distance because i've got my laptop only 2 feet away. I've hit the refresh wireless network button, but the only network visible is my 5GHZ. I've also restarted the router, no luck
I went into the router settings and made sure that BOTH SSID'S are broadcasting a signal.and are enabled (ive got the channel and other settings set to auto). I'm able to connect perfectly well to the 5GH band, and walk around the house, but nothing i've done, allows me to see the 2.4GHZ band? So far, my wireless reception is poorer than my old wrt310n.
I have some problem about dhcp via VMware 7.1. My client connect the wifi and get ip address well, then, i turn on VMware (inside my computer) and set as the bridge mode. I found that my VM cannot get the ip-address from dhcp server and I using WLC5508 version 7.2. I try to connect via Switch, my VM get the ip address well.
looking at doing the site survey before detailed implementation. we plan to use a wlc5508, AP3602, a good tripod/stand, PoE switch and AirMagnet to conduct the site survey. i'm inclined to use a single AP and just a guest SSID and let AirMagnet merge the readings on where i 'locate' the AP (on 1 VLAN)
A customer have a bad coverage in a corner of his branch office. He like to add a mesh AP (MAP) in the near of that corner.
I checked allready the documention about Mesh but i'm not sure if Flexconnect and Mesh works togheter. This MAP is in a branch office and the WLC is in the head quarter therefore he likes to uses Flexconnect togheter with Mesh.
I have a customer who is going to deploy a WLC HA AP SSO setup. I have recommended them to have 4 Gigabit SFP modules in each WLC5508.The customer now asks if it is possible to only have one or two SFP modules in the standby unit ? As he says it is properly not going to go in service one time within the next five years if he is unlucky.
We have five cisco WLC 5508 and one WCS .The WLC is running on 220.127.116.11 version at present but we want to upgrade it to 18.104.22.168 but on cisco site at download location , the below thing is mentioned...
WLC Version 22.214.171.124 will need Prime Infrastructure Version 1.3 to be managed, Version 1.3 is not yet available to download at this point of time
Access Point Model----Cisco 3501i Series
So i want to know, can i upgrade it to this version when we are having the WCS in our network ?
We’re deploying new WIFI towers at several of our vacation resorts and have decided to migrate from Wireless G to Wireless N access points. We currently have the following in each WIFI tower – Hotspot I’ve been researching and speaking to our partner pre-sales team, and have narrowed the choice down to deploying 3 x AIR-AP1261N-x-K9 at each of our towers. I have been unable to find suitable replacements to the 1watt Luxul 2.4ghz amplifiers we’re using, or really good N sector antennas to mount to the top of our masts. The 1260’s are all 802.af, so besides getting power injectors there shouldn’t be to much to think about.
