We have 6 1262 APs and a 2504 WLC. 5 of the 1262 appear correctly with 2 radios. One of them shows 1 radio. See screen shots below showing model numbers and interfaces on the AP with one radio available (All other 1262s show 2 radios as normal). Tried resetting the AP to factory default, but same result. Do I have a defective AP?

AP is in production since 1 year and it restarts seldom.

DIR-655 A4
Firmware: 1.35NA
ISP: Comcast
[Code].....
I play Diablo 3 and the lag that is created when the router restarts as well as getting booted, along with apps on my phones locking up are about to make me throw the DLink Equipment against the wall.
FYI - the Comcast modem was just upgraded to the Xfinity Voice modem becuase I puchased two Voice lines last week. The issue was happening before the new modem was insatlled, and after. According to the Comcast Modem's status page (192.168.100.1) the modem has been online for 4 days, 6 hours, and 31 minutes. So I know the modem has not been cycling.

I've recently installed a Cisco 2504 WLAN Controller with (5) AIR-LAP1042N-A-K9 Access Points. Everything is working fine as far as the APs connecting to the controller, and clients being able to connect to the WiFi and get network access, etc. The one problem I have is that one AP's b/g/n radio is not active.
If I go to the WLAN Controller management web page, and look at the Access Point Summary, it shows that I have five (5) 802.11 a/n radios active but only four (4) 802.11 b/g/n radios active. I know which AP is affected and clients can indeed connect to that radio using wireless 'B' but not 'N'.I have only one WLAN configured on the 2504 (WLAN ID 1), and one AP group name (default-group) so there are no special groupings of APs. I have been through every page of the Controller management page with a "fine tooth comb" and cannot find any place where I could accidentally be turning off the a/n radio for a single controller.

The network consists of 133 RAPs/MAPs/1131 APs and all joined the WLC. When I check the 802.11 a/n radio tab, I see only 129 APs and the 802.11 b/g/n tab I see 133 APs. I found out that 4 LAP1131 is not showing in the 802.11 a/n tab. I tried resetting the AP thru the WLC and still the don't see it in the 802.11 a/n tab.

Is there any way yo restart the WRT160NL from the web interface? I've had several routers before this Linksys and all of them had this option. In the web GUI of the WRT I can't find the way to do it and I have no other solution of unplugging it and plugging again.

We have two different entities we support and both are set up as autonomouse wireless groups. The SSID is the same though so they can use their 7921's between floors and buildings. The problem we have had is that the phones on the first floor were getting the IP's of the organization on the second floor. When you view the AP's on the phone the ap directly next to it on the first floor (the one its suppose to talk to) is listed first, The strange thing is that shows it is connected to the right AP (the first floor one). The AP on the second floor is also listed but its about third down. After the phone sits it will actually change IP's but not all of them. Their were a few phones that took about a half a day to get the correct IP.
My question is how do these phones grab their ip's? I know how DHCP works but I am needing to know specifically how the radio works on the 7921's. What is the boot up process? It appears that it must cycle through each channel starting with the highest and loop through a process in descending order: compare ssid's and then authenticate if possible. I am assuming it is seeing the second floor first because initially they all get the second floor ip. The second floor is on channel 60 and the one it should connect to is on channel 36 (We are using 802.11a). That's how I came up with my descending channel theory.

I have a westell DSL modem/router supplied by Frontier. It connects only to the telephone line and via cat5 to my main router, a cisco EA6500. Everything seems to be working fine, I just would like to understand a few things.I disabled wireless radio on the westell, enabled it on the cisco, so I have just one WIFI network active.I know I am not supposed to have two DHCP servers active, but I did not know how else to be sure the CISCO would get a good address, so I left DHCP active on the WESTELL, and also enabled it on the CISCO to provide service for the rest of the net.The WESTELL admin interface is at 192.168.1.1, and assigns addresses in this range.According to the WESTELL, the CISCO is at 192.168.1.27, which I assume was assigned by DHCP.The CISCO has an admin interface at 10.144.224.224, and assigns addresses in this range to all the other devices on my net.As I say, everything works.I can access both router admin pages with a browser on my main 10.144.224 network, and can ping both.But I don't understand why it works.What rules allow me to talk to the WESTELL admin page from the CISCO private network, but do NOT propagate the DHCP access which is at the exact same IP address.
It is great that it works. But should I really have disabled DHCP on the WESTELL and assigned a static address to the CISCO? Or is this situation actually provided for in the rules, not just a lucky accident that it works?Why does the scanner say that the CISCO DHCP is "Unknown" rather than Authorized or Unauthorized? Is there something I can or should do to get it to be "Authorized"? I can ping 192.168.1.1, but not the 192.168.1.27 (times out), and yet when I ping a non-existent 192.169.1.3 I get "Reply from 192.168.1.27: Destination host unreachable".

My mom has a Toshiba laptop that she got for Christmas and a lexmark all-in-one wireless printer. Every time she tries to print something to the wireless printer, the item just stays in the printing queue. However, once she restarts her laptop all of a sudden the laptop and printer seem to communicate, and the printer always starts printing whatever was in her queue from the previous time.so when she wants to print something it automatically starts printing, and she doesn't have to restart her computer every time to print stuff.

My WET610N crashes when I'm using it behind my PS3 while I'm watching videos in DLNA with the PS3 Media Server. Sometimes I can watch it during 1 hour without problem, somtimes it crashes and restart after 10 minutes of playing already. The restart is taking quite a long time, something like 2 or 3 minutes to get back to a Wifi connection. The router is still working properly while the WET610N is restarting.
The firmware is the latest 1.0.03, the settings are made for Video Access mode. I'm not using any encryption, only MAC address filtering.
My Wifi router is a Belkin N+ (F5D8235-4 v2000).

I am building a BOM for a customer and I need to present cheaper options than 3500 or 3600 APs. I thought of these two models but I don't know what models of antennas to pick.1602 is a 3X3 MIMO with 3 antenna connectors. How many 2.4 GHz and how many 5.8 GHz antennas should I pick for each radio?2602 is a 3X4 MIMO with 4 antenna connectors. In this case I suppose there are 2 connectors per radio.

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.

Not sure if it's new in WLC 7.4 code, but I now see "Dual-band radio" section everywhere in addition to "802.11a/n" and "802.11b/g/n". My dual band APs (for example 2600's) show up under both 802.11a/n and 802.11b/g/n as in the past. So what is this new category "dual-band radio" for then?

We are using the CISCO-DOT11-ASSOCIATION-MIB in a Cisco Air AP 1140 device with release 12/4(21a)JA1 to find out the radio type of wireless client (B/G or N). The clients in question are of type Wireless N and Wireless B/G. We are querying cDot11ClientDevType and cDot11ClientRadioType but the relation between the returned values and client/radio type is not clear:
2 devices returned: cDot11ClientDevType = 102 ==> pc4500Client(102) - client with a 4500 radio and ClientRadioType=2==> ccxClient(2) - CCX- compatible radio1 device returned: cDot11ClientDevType = 1==> unknown (1) – unknown and ClientRadioType= 1==> unknown(1)
Questions: On a Cisco Air AP 1140 device
What OID needs to be polled to find if the client's radio type?What value is returned by this OID if the radio type is B/G?What value is returned by this OID if the radio type is N?
