Hi Guys, Thanks for your suggestions on this but the issue is now resolved. Unfortunately I am not certain what resolved it as it went away after about 2 weeks. Thanks!

Hi, I had actually modified the DCA settings today to try and force it to do something. I had checeked all four boxes and set the sensitivity to high. This made no difference to the channel setting with both APs still on channel 1. I then manually moved the AP to channel 11 and it did switch. unfortunalty this didnt resolve my problem of poor performance and really high ping times. I am seeing around 500ms in pinging a local device. Is the channel issue a red herring for the performance issues? this worked fine when it was installed about a month ago and nothing has been added to the environment in terms of radio frequency. I will be adding the autonomous AP to the controller as soon as I have fixed this issue. Clients who are connected to the autonomous AP are getting much better results and this is located centrally in the office. the two WLC APs are equidistant from it. Any ideas?

Hello, I am investigating poor performance of a Cisco wireless network and think the issue may be caused by channel interferance from other accesspoints not controlled by my WLC. I have a 2504 and two 2600 series APs in an open plan office, I also have a standalone AP that the WLCs are replacing. (once all the testing is done all clients will move off this AP and it will be added to the WLC as a lightweight AP). What I am seeing is high latency and poor speeds on this wireless network despite only 2-3 laptops connected and 5-6 smartphones. When I look at a Wifi channel analyser on my phone I can see all the APs are using channel 1. even though the Channel is already very crowded the WLC does not change channels automaticallly. I have checeked the settings under wireless->802.11b/g/n and wirelesse->802.11a/n and the DCA is using its default settings. I have changed the TPC version to v2 which is Interference Optimal Mode but this has made no change. Half of the channels are free yet all wireless networks are crowded on channels 1-3... I would have expected the WLC to move itself away from this channel and use the uncrowded channel 11. When I look at the 5Ghz radios I can see that one is on channel 40 and another on channel 48, I am not sure how crowded these channels are as my phone and laptop are 2.5Ghz only. but at least it has moved them to seperate channels to avoid interferance. The WLC APs are about 10-15 meters apart from each other with no walls in between. Has anyone else seen issues like this and has anyone any suggestions to fix the issue? WLC 2504 running 7.4.100.0 Gerry

Hi, I checked the SSIDs and all of them have all selected for the radio policy. Is there a command I can use to see how each SSID is configured so I can compare them and see whats different? Gerry

Hi, I have a WLC2504 with three SSIDs configured and I have noticed that when my laptop connects to the main one it will only connect at 5.5Mbs. When I connect to the other two I get the full 72Mbps that my wireless card will allow. I have checked the SSID configuration but I cannot see anything that would cause this behaviour. Do you have any ideas/suggestions? Thanks. Gerry.

Hi, The SFPs are Cisco original products. We had another identical switch fail and they had Cisco originals installed with a very similar serial number.

Hi, I need to replace an older 3560 with a new 2960-S and am wondering if the SX SFPs I already have will be compatible with the 2960-S. Switch#sh inventory NAME: "1", DESCR: "WS-C3560-48PS" PID: WS-C3560-48PS-S , VID: V04, SN: CATXXXXXXXXX NAME: "GigabitEthernet0/2", DESCR: "1000BaseSX SFP" PID: , VID: , SN: H11K611 NAME: "GigabitEthernet0/4", DESCR: "1000BaseSX SFP" PID: , VID: , SN: H11K776 Here is the show inventory, I cannot find any way to get the part numbers of teh SFPs so if you have that command please also let me know. Thanks and regards. Gerry Egan

Hi there, I tried to upgrade the IOS on my internal AP and now I am in a reboot cycle. I have tried to manually boot the old and new IOS images from the rommon but neither are working. here is the output I am getting: ap: dir flash: Directory of flash:/ 2 -rwx 6563840 <date> ap801-k9w7-tar.124-21a.JY.tar 4 drwx 256 <date> ap801-k9w7-mx.124-21a.JA1 152 -rwx 548 <date> env_vars 153 -rwx 2775 <date> cpconfig-ap801.cfg 154 -rwx 2775 <date> back_up.txt 155 -rwx 3763 <date> config.txt 156 -rwx 168 <date> r0.rcore 157 -rwx 3775 <date> backup1234 158 -rwx 3553 <date> private-config 159 drwx 256 <date> ap801-k9w7-mx.124-21a.JY 307 -rwx 1048 <date> private-multiple-fs 11915776 bytes available (19566080 bytes used) ap: ap: dir flash:/ap801-k9w7-mx.124-21a.JA1 Directory of flash:/ap801-k9w7-mx.124-21a.JA1/ 5 drwx 64 <date> html 149 -rwx 5714717 <date> ap801-k9w7-mx.124-21a.JA1 150 -rwx 97896 <date> 8001.img 151 -rwx 287 <date> info 11915776 bytes available (19566080 bytes used) ap: boot flash:/ap801-k9w7-mx.124-21a.JA1/ap801-k9w7-mx.124-21a.JA1 Loading "flash:/ap801-k9w7-mx.124-21a.JA1/ap801-k9w7-mx.124-21a.JA1"...############################################################################################################################################################################################################################ File "flash:/ap801-k9w7-mx.124-21a.JA1/ap801-k9w7-mx.124-21a.JA1" uncompressed and installed, entry point: 0x3000 executing...
