Cisco Wireless :: WAP121 Host-pad Uses All CPU / Crashes Every 3.5 Days
Oct 8, 2012
We have 4 WAP121s running 1.0.1.10. After a couple of days of operation, they all become unusably slow. The admin web interface takes several minutes to load, and wireless clients timeout before RADIUS authentication can complete. Waiting long enough allows the diag info to be downloaded, which shows hostapd using all of the CPU time available: [code]
As a workaround, we used to use a small script to reboot them every night via SSH, but someone at Cisco made a less-than-brilliant decision to remove this advertised feature.
I upgraded the firmware on my wap121 and the URL redirect option is now gone. The docs all talk about using Captive portal but that is only on a wap321. How can I get the redirect back so customers who connect to my network see the site for our bar before they go on the internet?
I upgraded from the 1.0.0.3 to the latest (1.0.2.3)
If I connect my WAP121 directly to my router, it works just fine. But when I connect it to my SG100D-08P switch I can see it but when I connect, I get "limited connectivity" and it cannot "identify". The switch is PoE and everything looks to be working fine, but I have tried it both PoE and regular thru the switch; nothing works. Can't understand why if I connect it cat-cable going into the switch it works fine, but when I coonect it thru the switch, I have problems. I thought this switch was unmanaged, but something is going on.
I have an old computer with dead wifi nc and I thought that bridging it with was121 should work, but can't find anywhere any comprehensive documentation on how to set it up.
Just got several of these Cisco WAP121 AP's and today had a nightmare with one of them. On one of our areas with no broadband access we have installed the "Globe Surfer 3+ 3G Router" which incorperates its own Wireless AP.
I needed to get decent wireless access further down the building, so the idea was to use the WAP121 and setup WDS with the Globesurfer. No matter what guides I followed I could not get the WAP121 to talk to the Globe Surfer for internet access.
using the WAP121 and a Third party router ?OR, is this a case that the WAP121 wont work with a 3rd party router ?
I get the message "Firmware upgrade has failed. Please ensure that valid entries were specified in the required fields." when I try upgrade the firmware rootfs.bin.
Bought multiple WAP121s which are physically connected via CAT5 to the Ethernet NIC of a printer. Printer is in a warehouse with no Ethernet cabling -- but there is a wifi signal provided by a Cisco wireless router -- which is why we got the WAPs -- so PCs could get their jobs sent to the printer via Wifi > WAP > printer NIC.
Problem is the printers only stay visible on for about 15 min or so -- then disappear. Only way to get them visible again is to do a powercycle on the printer (not the WAP121). Then it stays visible for for another 15 minutes or so -- then disappears. If a Workstation sends a continues (-t) ping to the printer IP -- the printer will stay online and get print jobs.... but if activity is idle for 10-15 minutes... it disappears (power-save is off on the printer).
Firmware on WAP121 is current.
What setting on the WAP could be enable to keep the printers alive? have been trying to operate in bridge mode... What is the "best practice" here for connecting a printer to a WIFI via these WAP121s?
I just upload firmware1.0.1.10 on 2 WAP121. After the update and reboot, I was able to confirm the firmware version in the System Summary menu. The update is uneventful.However, the functions WDS Bridge and WorkGroup Bridge no longer works on two WAP121:
- For WDS Bridge, when I configure a Remote MAC Address with WPA Encryption and then I click on the Save button, nothing happens there. But it works well when I choose without Encryption.
- For WorkGroup Bridge, when I click on the Save button (even without changing the configuration), I have a message "Certificate file uploaded successfully" and another error message in the background: "error occured for query you send path . device.sync ... "
1.0.0.3 firmware is not available on your site, it is imposible for me to go back.
Although it does accept it in the setup wizard, you cannot change it in the vap list later on, it will throw a popup telling you there's an invalid character.
I've just bought a pair of WAP121 for testing and validation. I've set it up properly (user/password, IP, management vlan, NTP, SNMP, 802.1x, etc). So far, so good, everything worked as expected. I've downloaded the configuration to my PC, and also saved it to startup-config. I've powered off the unit, went for a coffee, and powered it back. All my settings were lost.
Tried to restore settings from the file downloaded to my PC, but no luck. After reboot, it was factory clean, no trace from settings in the backup file. I've set it up again by hand, power cycled it, and the **** thing reloaded to default settings.
Faulty unit, I thought, so I opened the other one I have, and repeated the whole thing, but same results. Test were made using the power adapter supplied but also tried with a catalyst 2960 with PoE.
I recently purchase my first Cisco products for a network for our church. I have a RV180W router, WAP 121 Access Point and a SR2016T switch for our network, which is just pier-to-pier at this point. We have 5 computers connected with ether net through the switch and all see the Internet and work fine. The wireless connection through the router is working fine with our wireless devices (laptops and i Pads). Where I am having issues is with the AP. It is in different area away from the router being powered through POE instead of the regular power connection.
My problem is this: it takes FOREVER to connect to the AP and to the Internet, even when sitting directly under the AP with full signal. Once connected, it appears to allow Internet connection just fine, but getting to that point takes 15-20 minutes sometimes. Also, when I come back the next day, I have NO signal at all, as it seems the AP has "timed out" due to inactivity or something. I have to reboot the AP and the router to get it all back up and running again. I need for the signal to stay up all the time or at least come on when someone connects.
So, what am I doing wrong here? I have recognized and authorized the AP through the router config, security is set up fine and I can see it once it comes up. I have the AP set up as a completely different SSID, although I would prefer to have the AP as merely an extension of the router's wireless network if possible.
I'm having this weird problem with an IP phone behind a WGB. The setup is like this: Cisco controller -> Switch -> switch -> AP (Air LAP1142) -> WGB (Air LAP 1262) -> switch -> IP phone.
The phone works, sometimes. Sometime for days, sometime for hours, then it disconnects and what I have to do then to get it working again is to run this command on the bridge. "no workgroup-bridge unified-vlan-client", then wait for it to disassociate, then run "workgroup-bridge unified-vlan-client" and after that it gets a stable connection (for a undetermined amount of time).
Here´s the WGB config: version 15.2 no service pad service timestamps debug datetime msec [Code]....
I am running big wireless network, with 20no of 5500 with 7.0.116.0 version. I have more than 20,000 AP's. All LWAPP which are up for more than 200-300 days has to be rebooted, this problem is with all AP's. clients are not getting connected,after reboot they work fine.how do the same from ncs.
Region : UnitedStates Model : TL-WR1043ND Hardware Version : V1 Firmware Version : 3.13.12 Build 121210 Rel.73912n (Beta) ISP :
I have tried to go through the tech support email but no dice. My router disconnects every two days. The sys light will stay solid and require a reboot and my computer connected to the router will be unaffected . I have a 30mb connection with only 2-3 wireless clients on at the same time as the wired. The response I got from tech support email after waiting almost a week without a response was :
Because there's not much we can do to fix the problem right now and TL-WR1042ND is more competent for your network, I suggest you to change for it.
If you still don't wanna change for TL-WR1042ND, change for a new TL-WR1043ND to have a try."
This is answer I get after already asking once why they want me to downgrade for a different router . What exactly the TL-WR1042ND is going to do for me that the one I have won't,but I cannot get a answer.I have no idea what they mean by "competent ", I don't believe my network is anything special and see no reason why the problem would be fixed by downgrading . This is the second router since December I have had and really dont feel like paying another 15$ shipping back to newegg for a refund.
I have a wireless schedule setup on my DIR-655. Works great. Now I would like to run different hours on different days. Have wireless up on certain hours during the week, different hours on weekends.
How do I set up a schedule to one one set of hours during the week, and a different set of hours during the weekend?
I have an E1200 wireless router. I need to restart it every 1 to 2 days. After restarting it is good until the next time. This has happened with different routers and upgraded firmware to the newest version available on all.
My set up is a 2wire router that connects to the internet, with an ethernet power plug connected to it. Over the other side of the house, I have the other ethernet power plug connected, with a Netgear router in access point mode.The main router is on 192.168.1.1, and the access point is on 192.168.1.3. The DCHP server is enabled on the main router with range 192.168.64 to 192.168.1.253. The access point has the DCHP server turned off. The routers have the same APN and security (WPA2-PSK).Also, the wireless channels don't overlap, channel 1 and 11.Now to my problem:The internet always works fine for a few days when the routers are turned on. But at some point between 1 to 3 days later, every computer can't obtain an IP address while connected to the access point. But all computers can connect to the main router (i.e. when closer to the main router than the access point), and then go near the access point and it keeps the connection. If I reboot the access point, then everything works again for a few days.
Region : UnitedKingdom Model : TL-WR1043ND Hardware Version : v1 Firmware Version : TL-WR1043ND_V1_120405 ISP : BT Infinity (1)
I have a TL-WR1043ND v1 with the latest firmware installed TL-WR1043ND_V1_120405.I loose access to the router (can't see web page, can't config, can't restart).I have a Linux server on the Ethernet, and uplink through 200Mbps powerline adapter to the BT Infinity modem. A few other devices on the wireless.The router works well and I prefer it to the BT Home Hub 3 for fiber because it proved to be faster in many cases as tested.But after a few days the web interface becomes inaccessible. It's like the web server died or something. Browser says connection reset, if I try telnet to port 80 says connection refused.Actually I just did a full netcat scan (sudo netcat -z -v -192.168.1.1 1-65535) and all ports say connection refused.Ping works - I can ping it allright.DHCP server works too, just restarted a computer and got IP from the router.Port forwarding works as well and DynDNS seems to work as well as my ISP changes the IP periodically and I can always find the updated one.All works - exept I can't access the router in any way!If I restart (remove power and plug it back in), it boots and I can access the router again.So restarting won't work remotely, I actually have to go home to re-plug it!
recently i bought a x1000 for my home network. I use the x1000 as router an wireless accessPoint between my WAN internet uplink an my home network...yesterday the router hang up completely. internet stoppp working. so i tried to access to x1000 to check if PPPoE connection was still active. But it did not load the webinterface. I tried to connect over WLAN and LAN. Both not working!
I have a host that can successfully connect to a PIX 515E (7.x OS) via VPN Client; however, I have no IP routing to the LAN from the remote host.The VPN IP pool works finem,The LAN default gateway is the inside interface on the PIX; the network is flat L2 behind it.The default route on the PIX points out; no other routes are defined,The VPN remote host can be pinged from LAN hosts, but the VPN remote host cannot ping any LAN host, not even the PIX inside interface.
Running ACS5.2, Windows XP Pro, Window Server 2003 and Cisco Anyconnect Client. When the machine name password changes between the PC and the AD server the ACS will error out with "24485 Machine authentication against Active Directory has failed because of wrong password".TAC has been working with us on this and sees the error in the logs but does not have an answer on with to do to solve this. It has the same problem with Wireless Zero. Once the PC is rebooted the error goes away for 30 days. We are in a hospital setting so this is a not just a minor problem
I am running a 1921 with 15.0(1)M4 on it. The router has a /29 public block assigned to it so I have a public IP for my router's GW, a public IP for the WAN interface on the router, a public IP for PAT and the three remaining public IPs I use them as static NATs for internal hosts.
My problem is that the particular static NAT assigned to static host1 seems to "hang" every few days. You can ping the public IP and it will respond but the rest of the services of the host like www, ftp and telnet do not respond. If I reboot the router then all services of host1 will work again. Note that all other static IPs including the ones used for static host2, host3 and PAT will always work and never give any problems.
I am fairly certain that this is not a config problem so I have shuffled around the public-to-private NAT entries. Basically whatever public IP I assign to this host1 will at some point hang. The host2, host3 and PAT always work and never hang no matter what public IP I issue to them.
So since it isn't a problem with the public IP I changed the private IP of host1 and still it hung!! This host1 happens to be a linux box. host2 and host3 are a Windows server and a different flavor linux if that make some kind of difference.
my PC and laptop are both suddenly running sluggish since yesterday morning. pages take forever to load; slow to start videos, etc. i called ATT this morning...the auto test said i needed to talk to someone because there was a problem noted. but the live rep ran tests and said the speeds were within the norm for my service. i asked her why the auto test reported an issue, and she checked, only to come back to say "it's a problem with the modem." oh, and a new one from them is $80-100+
I have the problem that our ciscoworks server gets out of memory after few days. The memory utilization is always getting higher an higher (above 95%). Sometimes it is only after 3 days and sometimes it is after 1 week. So it happens not regularly. I have made an screenshot from the services which use a lot of memory. And at this time the memory utilization is getting higher and higher again....I think there is a problem with tomcat or dbsrv10.exe, there are also a lot of cwjava.exe running.
I have copied my computer's time in the router time setup under Time in the "tools" section of the router setup. After a few days of the router being up without a hard restart, it has lost 10 minutes somehow. I went to the logs and cleared them out and then looked at the entry showing that the log was cleared and looked at my computer clock and the time stamp of the log entry, and it was 10 minutes slower than my computer clock that I had originally set it from. I have a clock plugged in by the computer, and my computer always matches the clock that it plugged in, so I know it isn't my computer loosing time. What is going on here? Why does the router loose the correct time after it has been up and not unplugged or rebooted at all? I know that the router will loose the time if you unplug it, but this isn't the case here.
I'm experiencing some problems with a new X1000 gateway. The device works very well for 2-3 days. After that period, it seems to just freeze. I can connect to the wireless, but no IP address is leased. Wired clients keep their IP address, but can't connect to the internet. Communication between the wired clients is still possible (Ping, CIFS, LAN games,...). The DSL sync LED is lit as is the Internet LED. The management interface does not load. Doesn't matter is there has been a lot of internet traffic or virtually none. The only way to make it work again, is to cycle the power.
I've been fiddling with the different features from all off to all on, but the problem persists. I even got a replacement device, but that has the exact same problems. My ISP tells me that the Cisco and Linksys devices are fit to work on their network. I'm using a Zyxel gateway at the moment, which is absolutely fantastic, but has no wireless and useless QoS management.
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.
