Cisco Wireless :: 7921 Phones Disconnect Ten Time An Hour
Jun 27, 2011
One of my 7921 phones disconnect ten time an hour and during conversations. Sometimes, people who call on this phone are redirected to the answer message.This phone is connected through WIFI network and Cisco Callmanager 4.2 manage all phones (we have about 80 phones on the network). I thought it was a problem with the phone but I exchange with another one and it's exactely the same problem. The problem is just for a line in particular. All the 7921g phones in my company are configured from mac address in the call manager. This problem occured after a storm but I'm not really sure that it's related to.

I've noticed this in the last few days, but my internet seems to crash at the exact same time (29 past the hour) every hour. We've recently had a new modem in, and was working fine. I recently had a mass clearout of a lot of things in my PC (got rid of 500 gigs), so I'm wondering whether I may have deleted something which has caused this.

I have the DIR-655 rev B1 with 2.03NA firmware. After 7 days the system time falls back an hour. The timezone settings are correct and I have used both 0.us.pool.ntp.org and DLink's time servers.

A couple of users on my network complain about timeouts. They access the same server which runs a SQL server. People from outside world can access it without a problem but internally it keeps timing out. I have also noticed that VoIP phones have a delay internally. So if i pickup my phone and dial an extension the other person can't hear me sometimes but i can hear him.
I have experienced the VoIP problem but have never had any time outs on my machine. I tried packet capture on a couple of computers but i cant see anything out of the ordinary. Alot of ARP, some STP which i think shouldn't reach the machines, dropbox traffic etc.

We are using the cisco sa540 router and shrew VPN to connect to our buiness network, mostly to connect to the workstations with RDP. Now we wonder if it posible that the connection will disconnect automaticly after an idle time of for example 30 minutes. And if so, how can i configure it?

I have a CUCM BE environment with a number of remote users with 8961 phones connecting to an ASA 5501 via AnyConnect. The phones register fine and can make inbound/outbound calls as well as four digit dialing to other users at the corporate site.
The problem is when a remote user tries to four digit dial another remote phone. The called phone will ring but there is dead air once answered and then the line goes dead.
This sounds like a routing issue to me. How to get AnyConnect clients to be able to reach each other?

I just recieved new 7921 phones. I cannot get them to pick up a dhcp address
I keep getting DHCP "Timeout's" and " Configuring IP" . The ould 7921's and the new 7925's work just fine. I have tried removing and reconfiguring the WLAN and Interface on the Controllers. I even removed and reconfigured the DHCP scope in Infoblox.

We just installed MSE with CAS (7.0.201.204 software) and everything works fine and clients are shown on WCS floor maps except for Cisco 7921 wireless phones which dont appear in the WCS map.

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 configured a cisco UC520 with inbound called coming in on FXO port 0 and have configured it as a co-line. I have 4 phones set up on the system including the wireless 7921 phone, the problem is that if i answer the call on the 7921 it does not give me the option to hold or transfer the call however the other phones do (7931).

We have a new deployment where we have 5 total 7921G wifi phones connected via 2 AP541n access points, one connected to a ESW520p switch and then to the UC540 and the other connected directly to the UC540. The wifi phones are intermittently giving no audio when calling each other, however, calls to the PSTN consistently do have 2 way audio. Is this a security issue perhaps? We are running the latest CCA software pack as this is a brand new deployment, also the AP's were upgraded to the latest firmware.

We have some remote H-READ APs at a branch office and a 7921 phone which drops calls/loses audio when roaming between APs.We are just using WPA2 without any 802.1x or CCKM/PKC.
Do we absolutely have to set up a radius server/8021.x/EAP to enable fast roaming?We had 2 AP's autonomous with WPA2 before and roaming didn't seem to be an issue. We now have 4 APs over WLC in the same office and the phone calls are very unstable.

i just setup an RV220W as my home router. Everything connected fine, etc. however, one of my wireless devices (it's a security camera) disconnects after 1 hour. I am able to reconnect the device if I either reboot it, reboot the RV220, or disable / re-enable the Port Forwarding rule I've established for it. Other wireless and wired devices do not have any issues. In the past, I had this same camera working for over two years over wireless while it was connected to a Linksys E2000 router. I enabled the logs on the RV220W last night, and the error message that I receive is: secureBit not set in GTK Msg2. I've got the same SSID on the RV220 that I had on the E2000, same port forwarding, same MAC address client list, etc. Like I said, none of my other wireless or wired devices disconnect at all, just this camera, which worked flawlessly until I switched routers.

I just bought WRT54GH router. I have one PC (running Ubuntu) connected via Wireless.Every 5-10 minutes I get disconnected for a short period of time (about 10-30 seconds). During that period I am able to access router configuration page, but can't connect to the "outer" world... Surely it's not about my Internet provider, since connecting the PC directly to the Internet cable works fine with no "disconnections".

Not sure if I have a defective router, but if I unplug it I then need to wait at least a half hour to plug it back in. Anytime sooner and it won't broadcast a SSID or connect to the modem. This is a huge inconvenience if you want to change router settings and then you need to restart.

I just bought a WAP321 Wireless AP. I wonder why it cannot sync with our time server automatically. Every time I reboot it, the system time become "Fri Dec 31 1999 12:00:00 UCT". I have to do the sync manually by clicking on the "Save" button under the menu Administration > Time Setting.

Got my E4200 a month ago, and have since been experiencing problems with movie streaming between my server and my Popcorn Hour A110. All kinds of movies stutters randomly and becomes unwatchable. Streaming of the same movie from my server to my laptop (connected wirelessly) causes no stuttering.
I have been doing some troubleshooting and determined that it is not the server's fault (it achieves transfer speeds of 60+ MB/s through Samba). I have also ruled out the possibility that the Popcorn Hour is the faulty component.
Lastly, I just tried switching from the E4200 to my old D-Link DIR-655. This has effectively removed the stuttering, leading me to conclude that it is the E4200's fault.

AI have a Dir-825 router. The 5GHz is turned off and the wirless is on G/N. I have shawcable for my isp and my firmware is 2.06 and its a Rev B Router. I also have Qos Engine on for allowing me to have 2 xboxes on Open NAT.problem is my wireless signal for some wired reason is VERY weak. A while ago it used to work really far way outside. It was around 150ft distance at 4 bars. Now for some reason I can't even go upstairs without getting a 1 or 2 bar signal.

The environment: 20 X air-ap1141N-A-K9 (these are standalone) in three different buildings with either 1 or 2 units per floor depending on sq. footage. IOS is c1140-k9w7-tar.124-25d.JA1.
Problem Users running various tpyes of wireless cards on windows XP SP3 get disconnected periodically throughout the day whether they roam or not. This disconnect problem started happening after we replaced older 1200 series units running wpa and tkip and replaced with 1141n running wpa2 with aes. Users running windows 7 do not get disconnected. However there are very few W7 users on campus as this point in time.
I set up a single test unit shown below and associated two laptops to see if they would disconnect. Not once did I lose connectivity.

I am using WRVS4400N in our company as a AP only. Before some time, when majority of wireless clients were computers, everything worked fine. But now, when mobile devices are in majority, something strange is happening. While portable computers still work fine, smart phone and tablet have extreme problems.
Although there is indicator that WiFi is connected and signal is strong, there is no guarantee that there is an internet access. Most of the times there is none. You can fix this by simply disconnecting and connecting WiFi on mobile device, but after a while, internet will be inaccessible again. Or you can wait and eventually you'll get to the internet access again.
