I have been setting up a WAP 321 which has been unable to retain it's settings across reboots.
What I have found is that if I leave the Timezone set to USA (Pacific) the WAP 321 can be rebooted without losing config, but as soon as I set the timezone to United Kingdom the next reboot will cause the device to take a long time to reboot and will have then gone back to factory default setings.
Our clients claims the problem of loss startup configuration with power outage especially with 877 series , all the router are configured to store configuration in NVRAM ( confreg = 0x2101),

View 1 Replies View RelatedI have an issue with a loss of connectivity after 10-15 seconds. I have a Cisco WLC 2504 controlling a Cisco 1242AG AP. The following is the topology.
Wireless Client -> 1242AG (AP) -> Port 3 WLC 2504 -> Port 1 WLC 2504 goes to fa0/2 on 3560. Port fa0/1 goes to ASA5505 (Inside)
All devices are on VLAN 10 10.50.1.0/24. AP is getting DHCP just fine and is associating with the WLC just fine. I connect my laptop to it and it connects just fine.
I then ping the gateway (ASA) 10.50.1.1 or the layer 3 interface on the switch 10.50.1.7 and it is fine for about 10 seconds, then it just dies then comes back in a few minutes and then goes away again. I have looked for duplicate IP's and can find none in any arp table.
It I just ping the controller 10.50.1.20 it is completely stable. I have moved the WLC directly off the ASA5505, moved the switch port, changed cables and the problem follows. I have even moved the AP to be directly off the switch instead of the WLC and the problem still occurs.
I am having issues where different laptops are dropping packets when communicating to the WAP on the RV220W. I have placed 3 laptops directly next to the router so there is no chance for walls to interfere. From each machine 1 at a time I perform a continuous ping. Here is a quick output from one of them:

I am connecting to a Wireless network, through a ZyXel ZyAIR G-4100v2 router. My problem is that I am experiencing very regular packet loss every minute or so. This lasts for around 5-10 seconds on average. I am running XP with the latest service pack. So far, I have checked out;Wireless Zero Config scanning of new stations (disabled that feature).Xirrus network scan (signal is fine and consistent). I am not suffering from any degredation in signal, the problem seems to be that the router is simply not allowing anything through at regular intervals.
View 1 Replies View RelatedI have a WLC 2504 with 10 licences running 7.3.2.112.0. I have 7 AP joined from different remote sites (WAN). The other APs are 3602E.
I got a brand new 3602I that I want to join, from a remote site and I am getting these error messages and cannot join :
*Dec 21 14:35:18.859: %CAPWAP-5-DHCP_OPTION_43: Controller address x.x.x.x obtained through DHCP,
As far as I can tell, the AP seems to be loosing packets that are coming/going away from its own subnet.
AP address : 192.168.1.1 (mask 255.255.255.0)
WLC address : 192.168.2.1 (mask 255.255.255.0)
If I ping the AP address from a computer in the *same subnet*, I get a perfect 0% packet loss.
If I ping the AP address from a computer in ANY *other subnets*, I get about 50% packet loss.
If I ping anything else *other than this single AP*, to and from any other subnets, I get a perfect 0% packet loss.
Only packets orginating or sent to the AP from other subnets are getting lost.To me it looks like there is something wrong with the routing table of the AP, as if some packets were not properly returned ?
I have a RV220W with the latest firmware (1.0.2.4) and I loose about one in every 20-40 packets.
I have tried with both wireless/wired, on different ports, laptops, and Ethernet cables.
My configuration is fairly simple:
1.) I reconfigured the default subnet
2.) I setup a WAP on the same vlan (VLAN1)
3.) I setup a WAP on Vlan2 for guests
Other than that, settings are out of box (save a hostname/etc).
just purchased it, and am thinking I'll have to phone Cisco for RMA.... There is a similar thread where people noticed this on wireless (not sure if they tried wired as I have). RV220W Packet Loss over wireless
we have two WLC model 5508 with software version 7.0.116.0 (25 ap supported for each), i tried to add a new access point air-lap1131ag-e-k9 but after five minuts (maximum) the ap reboot, i replaced :
- power injector
- AC/DC adapter
- patch ethernet
- switch port
- switch
- ip of the access point
- reset a default of all access point i tried
- reboot of both wlc
I took the ap and connected directly to the switch (with or without power injector), but the access point reset with this reason.
Basically my laptop was connected to the Internet fine and has been for as long as I can remember but today it just suddenly stopped working and when I clicked on 'View available networks' it gave me the message 'No wireless networks were found in range. Make sure the wireless switch on your computer is on. To see an updates list, click "Refresh network list."'. The strange thing is that I'm connected to the wireless network on my phone so it must be in range.I'm using a Samsung laptop (Not sure of the model) that is running on windows xp.It doesn't have wireless connectivity built in so I am connected to the wireless using an 802.11 USB Wireless LAN Card network adaptor that is made by Ralink Technology, which is working properly according to the device status.

View 1 Replies View RelatedI had to change from a WRT300N wireless router which died to a new E2500. I noticed that the speed my computers report that they are connected to the wireless network connection is now 144.5 mps, versus 270 mps with the WRT300N. There is no change in location of the devices or computers. The computers use a WUSB300N adapter. Is there a setting or setup that needs to be changed?
View 3 Replies View RelatedI seem to be having packet loss with the E4200V2 which is upgraded to the latest firmware as of today, 1/18/12
The application is accessing a security DVR which uses a RTSP / RTP stream. Of course this requires certian ports to be forwarded in order for this to work. This works flawlessly with a WRT310N or a Cisco 871 Router so I know the port forwarding is correct.
With the E4200V2 it works intermittently, I can replace EV4200V2 with either the Cisco 871 or the WRT310N and there are no issues.

Connectivity has been intermittent the last few months and now none at all. Laptop can see the router but can't connect. Tried connecting via hard-wire to the router but no connectivity 2) tried downloading a driver update but resulted in a message saying "software can't be installed hardware doesn't exist". Check of the adapter through the device manager shows "device is working properly". Have two other dells on the same router and neither have any connectivity issues.
we took one of our controllers and turned LAG on and since then it is unreachable on the WCS. The controller is running version 7.0.116.0 and the WCS is running 7.0.172.0. I can access teh WLC no problem through web interface and CLI, as I can also do this with the WCS as well, but the WCS cannot access the WLC.From CLI i can ping the WCS from the Controller and get a response, but from CLI on the WCS, I cannot ping the controller.

Hardware Version : V3
Firmware Version : 3.13.9 Build 120201 Rel.54965n
ISP : TDS
Currently I am using 2 WA5210Gs and a WR941ND to send my wireless connection from one home to another. The original home utilizes a TDS DSL modem/router combo. Everything works great, but then generally withing 24 hours I will randomly drop my internet connection in the second home, but the network is still up and running strong. The modem is not the problem, because I am able to grab a faint signal from the WA5210G AP connected to the modem and access the internet, and the client WA5210G AP is running at full signal. If I power down the router and restart it, the problem is fixed, but happens again within 24 hours. Originally I changed the IP on the WR941 thinking it was an IP conflict with the modem/router, but the problem occurred again. I also tried switching to unicast DHCP, but the problem still persisted. I looked for a firmware update, but couldn't find a newer version..
well, i just bought an E4200 and, by the way, was very hard to configurate. But the real problem is: if there is a power loss, both modem and e4200 lights up, but no internet connection is provided.Even the SSID desappear. I trried to disconnected everything, reconnect by parts, but no success.I wired connect the E4200 to my iMac and the router was ok, configurated.Then, i reconnect to the modem and all worked ok.Now im testing possibilities and is i reboot the router, the net desappear and i have to try possibilities till it works.
My older router connected automatically, without a problem, but i decide to buy "the best" brand and its top product". Now im disappointed..
Twice i realize that if the connections drops out, i have to disconnect and reconnect the internet cable from my E4200...
All of a sudden I started experiencing occasional loss of communication with my router. I tried updating the firmware to the latest (1.0.04) but am still experiencing the same thing.I don't lose internet access, I lose connection to the router itself. If I power cycle the router, the connection is re-established and I'm able to access the router and in turn the internet. I'm seeing this on both wired and wireless connections. Last night the Cisco logo actually turned off when I lost connection (this was a first). When I power cycled, connection was restored and the logo lit up again.
View 3 Replies View RelatedHaving several issues w my E1200. For quite some time I have had intermittent loss of internet connection. This was somewhat true even before I got a wifi router. & it has continued. Recently it has been even worse & I'm not sure if it is my isp, my cable modem or the router. ISP came out & checked & said signals looked ok, although modem is old.Now i find out that the version of Cisco Connect that i had been using is incompatible w Mountain Lion so it won't work now. & newly downloaded dmg files say they are damaged (or that app has been modified or damaged--I'm not in a position to tell which but same results after I downloaded a 2nd time).
I have been having more frequent loss of internet connection at home. & when I click on the wifi icon to check, it shows it looking for networks. Also it has not been uncommon to see that it has switched to my guest network.Why would it switch to my guest network? What is the difference between the 2 besides the fact that I guess the guest network doesn't have access to everything on my regular network (which right now is only my iPhone, but may get wireless printer).Also when it shows the lists of networks that it "sees" my guest network does not show a padlock icon so what does that mean? It does have the default password.
Also because I had no idea that Cisco Connect was not compatible w Mountain Lion I didn't even think to check for upgrades before I upgraded to Mountain Lion & now I can't open Cisco Connect. Shows unsupoprted OS. & I'm also stalled trying to update the firmware for the router.I'm really beginning to see why it was cheaper than an Apple Airport Express. Even at a very low hourly rate, the lost time spent when this has not been working right has not been worth what I saved on the purchase price.
A while ago I bought a WRT320N as a trade-in offer, unfortunately I had around 20% packet loss on my connection after I set it up. If running directly through my cable modem I had no connection issues at all.I was running the whole setup cabled, and have no peripherals using the wireless connection.The router was returned to the retailer for RMA, and in the end I got the purchase credited.My setup ISP: Dansk Kabel TV (danish provider for internet, TV etc.)Modem: Netgear CVD31T DOCSIS 3.0 compliant Cablemodem (I do not have access to the modem, as it is provided by the ISP. I have now bought an E2000, and set it up in the same manner as the previous router.This has returned the same problems I had with my previous router.Updating the firmware didn't make any difference.Using Pingtest.net as my test reference I get results like this.when connected directly to the modem I get 0% packet loss, max 20ms ping and jitter is 2-3ms.Have I been so unlucky to get 2 faulty routers in a row, or could there be some problems with Linksys routers and Netgear?I have unsuccessfully tried switching cables without any change, tried moving the router "far" away from the modem, monitors etc to see if there could be any interference from the wireless.
