Cisco Wireless :: Intermittent Connectivity To WAP4400N
Oct 1, 2010
I have 2 WAP4400Ns that were manufactured in July 2007. I've experienced some problems with dropped connections even with a strong signal over the years but recently, I've had long stretches where I cannot connect wirelessly to either unit. It works for a few hours then can't connect for half the day. I have no problem connecting to their admin pages over the LAN, just wirelessly. I look at the units and the power light is steady green while the Ethernet and wireless lights flicker rapidly. This looks no different when I can connect and when I can't. Connectivity doesn't depend on location; I can put my laptop right next to one of the units when they are malfunctioning and still can't connect. I tried changing the broadcast channel but it seems to have no effect. I rentered the WEP key that I have used for years and it doesn't have any effect. Settings are pretty much factory except for changing the IP address of one of them (so they can be in the same LAN) and customizing the SSIDs and security keys.

My advent 4211 has intermittent wireless connectivity.I have tried resetting the channel on the hub, but have had no luck thus far. Also I have updated the driver from Realtek, but the problem persits. I have also moved the hub to another location.The thing is that I have another Laptop which has no problem connecting.

We are experiencing problems with Apple Ipads on a large scale network that we install and maintain, the Ipads seem to join the network with no problems (bit slower than laptops etc) but will then disconnect for no apparent reason at random intervals. We have ran laptops on the same AP's and in the same area and no similar probems occurred, we are using IOS Cisco 1041's and 1042's, we have seen one of the Ipads's sitting quite happily on a 1042 2,4ghz radio and then it disconnected and went to the 5ghz radio. We are getting similar disconnects on the single radio 1041.

I saw some other mentions online of intermittent internet connectivity using the factory-installed Intel Centrino wireless-N 1030 card on various new Dell computers running Windows 7, but didn't see any resolution to the problem.
I can connect directly to my router via an ethernet cord, but trying to use the wireless card gives me intermittent connectivity. I will pretty quickly lose the ability to load a new page if I'm browsing with IE or Firefox, and can regain it (temporarily) by disconnecting/reconnecting or letting the wireless manager troubleshoot, during which it resets the wireless adaptor. Doing a continuous ping of my router gives me anywhere from 30-70% data loss and lengthy round trips (I am currently one foot away from the router). Other (ancient!) computers work fine on my router; I have updated the router's firmware/reset it many times, etc). I didn't specifically go download a new driver for the wireless card, but going into its properties and having it search for an updated driver results in it reporting it already has the most up-to-date driver.
I spent a lot of late nights talking to Dell support, and their eventual fix (after a complete reinstall from the factory setting partition) was to set up my home network as a WEP, which I'm not happy with due to it's poor security compared to WPA2/WPA. This appeared to resolve the connectivity issue (why??). But I feel like I should be able to use WPA2 security with a brand-new laptop. So I changed it back to WPA2/WPA and tried installing all the critical updates that Windows Update could find, including SP1, and then looked at some continuous pings of various webpages and of my router itself.
Then I noticed my ping round trip time was awesome and they were 100% successful while my computer was plugged in with the power cord, but this unfailingly changed to reporting unsuccessful pings and having 1000ms round trips as soon as I disconnect the power. Seems like the on-battery power settings are starving the wireless card?
Also, I'm sure my initial intermittent connectivity (before the complete OS reinstall) was still occurring while plugged in with the power cord, so I'm not sure if the reinstall fixed some aspect of the problem, or whether the appearance of success while plugged in now is just temporary. Perhaps my card is just bad and I need a new one? I'm using the factory default power settings and the factory-installed wireless card (and I couldn't choose a different wireless card when I built my laptop)

I have recently bought a new wireless card and it is giving me grief. Until now I had been using a laptop to pick up the wireless signal from my router, and pass it along to my PC, and have been receiving excellent speeds (30 Megabit) despite being 2 floors above the router.
I bought myself a Sitecom N300 card to go in the PCI slot of my computer, and my connection is generally extremely slow, and often drops completely for minutes at a time. The strange thing, however, is that it still shows medium to strong signal strength, even when the connection drops completely!
This is completely baffling me! I can't work out what could be causing interference, or why the signal strength doesn't go down when the signal does, or why the internal laptop wi-fi receiver seems so much better than this new card with 2 massive aerials. Unfortunately my ability to move either my PC or router is somewhat limited
I'm running Windows 7, fully up-to-date, and the router is a BT Home Hub 3

After much investigation I finally found what I thought was the firmware upgrade for my WAP4400N access point, I downloaded the file which is a .img file which seems a bit off I think. Anyway when I go to the admin page it decides its an unknown file format. Could someone explain what I am supposed to do with it!
I have to say I am very dissapointed with the whole support function of this site it is very hard to navigate and when you do think you have the correct link, its not. How very helpful!!! I suppose there are networking gurus who look after multi 1000 user systems who understand how the site works and think its fantastic. I support 5 PC's and 7 laptops on top of my normal job, it should be easier.

We have a client that moved to a new office and WAP4400N can no longer reach entire office so we need to put in repeater. However, we have already tried one that isn't compatible so which model of wireless repeater is compatible with WAP4400N. Note, we do not use Wireless N and will not be any time soon due to older devices.

I have 2 WAP4400N access points, each has a different version of the firmware installed and one has options that the other one does not.I have one access point running
If I visit the Cisco site for firmware updates, I see that only one version of firmware is available for this access point... 1.2.14.I realize that Linksys is not Cisco's main area of business, but if you are going to provide downloads for access points you could at least make sure that you have the latest version available.

I have a WAP 4400n and need to expand the range.Linksys support suggested WAP200 to repeat the signal, but I am probably missing something, because its not working.WAP200 can see the WAP4400n, recognizes its MAC adress, but does not work.Anything to set on the WAP4400n to let the signal to be repeated?

I have a Cisco 1242 AG wireless access point with the goal of having multiple SSIDs. I set up one network which broadcasts correctly but only sometimes can I connect to it.
And, even if I connect to the network, I cannot get a DHCP address for the client.Other devices connected (but not through this Access Point) to the associated VLAN 60 can get a DHCP address and connect just fine.Here is the configuration for the Cisco 1242 AG access point in question: [code]
Lastly, here is the information on VLAN 60 from the distribution switch. As mentioned, other devices connect to this VLAN and get IP addresses just fine.

I've been running into an issue for the past week or so where my wireless adapter intermittently can't contact my router.When it occurs the network connection reads as having limited connectivity. I'm unable to send requests to load webpages, and videos and the like stop loading. Sometimes the network disconnects entirely. After this occurs, I can't connect again for a few minutes. My connection consistently reads as having 2-3 bars available. The issue tends to occur frequently, often every 15 minutes or so. Strangely enough, I have been able to play bf3 online for over 40 minutes without connection problems (I quit before any occurred - not sure if any would have). So far I've tried the windows troubleshooter, updating the driver to my wireless networking adapter, manually assigning my network address (tried 192.168.1.4, 192.168.1.5, etc), setting my 802.11b preamble to "Long only" and performing a system restore. I have rebooted my machine as well.
My technical specs are as follows:I'm running Windows 7 Ultimate N 64 bit edition with service pack 1. System has 8gb Ram, an i5-3570k processor and HD7850 graphics card. Motherboard is the Asrock Z77 extreme 4. My wireless network adapter is the TP-link TL-WN722N. The adapter was working fine for some time before this issue appeared.My router is an old U.S. Robotics Wireless MaxG Router. It seems to work fine with other computers in the household, although it does require fairly frequent power-cycling. Running ipconfig on the command prompt while the internet is working returns:

I'm being kicked off my VPN connection back to the home office on occasion, using a Nortel VPN client. The logs show:
4/2/2013 9:58:26.883 [ENGS] -I-VerifyServerIsAlive: ISAKMP had traffic (after keepalive).
4/2/2013 9:58:27.383 [ENGS] -I-VerifyServerIsAlive: Set receivedData FALSE.
4/2/2013 9:58:28.555 [ENGS] -I-Protocol not recognized - message dropped.
4/2/2013 9:58:44.586 [ENGS] -I-Protocol not recognized - message dropped.
[code]....
the common fault seems to be DynamicDnsCleanup causing the trouble.(causes routing table to change, knocking down the VPN....) Is this a function occurring in the router? I can't find search results showing so.

I recently updated the firmware in my WRT160N V3.Ever since, the wireless signal is intermittent.It worked all day yesterday, and now today it doesn't connect at all.I can't remember exactly the settings I used to have before updating the firmware, should have written them down.From looking at articles on this site, I have the following settings:
MTU Manual 1492
MAC Adress enabled
Network Mode: Mixed
Channel Width 20MHz
Channel: 11

I have a WRT120N router set up with WPA2 security and set to channel 11. Everything is connected via the router (one wired computer, up to a max of 5 laptops but just 2-3 on a regular basis, a wired xbox360, wireless wii and a few cell phones occasionally connect wirelessly). Everything has been working great, been getting at or very close to the 6mbps we are supposed to be getting...until the past 2 weeks. Suddenly the connection drops repeatedly throughout the night. It either shows local only or just "limited connectivity". Normally when this happens my laptop will pick the signal back up when things are normal but I am actually having to disconnect and reconnect for it to work again. It happens again in about 30 min to an hour after that. Also, our connection speeds are showing at .5 - 1.5 instead of 6. I plugged the cable modem (the 660 series sent out by sprint/embarq/century link (or whatever name they are going by today lol) into the computer directly and got 5.7mbps. I have tried power cycles of both pieces of equipment but that doesnt work.

My router has been dropping the internet connection for years. The ethernet connection to the desktop works fine all the time. The problem is only with the wireless connection. About every 1/2 hour or so the router will drop the wireless connection and neither or my 2 laptops can find the network. Unplugging the router and replugging it in solves the problem temporarily, until it drops it again. I updated the firmware to 1.0.4 and that yielded no changes.
Router: WRT54G2 v.1 Modem: Siemens Speedster 4100 (part #060-D141-A12) My two laptops running wirelessly are Macs. The desktop is PC running Windows Vista.

Bought an E4200 to replace my Netwgear router and am experiencing the following problem.One of my wireless boxes serves as mu mail server. I've been running this configuration for years so the only thing that has changed is the router.The neworkd is up and all wireless clients can connect, but after some time, access to the mail server just 'freezes'. I say freezes as the nework icon (i'm using ubuntu' still show a connection. In addtion, there are not error in any of the logs. I just seems that the mail server and the router just stopped communication.

I have been having a problem with my router for the past two weeks and my ISP (RCN) has done nothing to fix it so maybe with our nerd power combined we can find a solution!My router runs fine about 60% of the time, I get 20-24Mbps down and 2Mbps up connect wirelessly. the other 40% of the time the download speed suddenly drops to 1.5-2Mbps down and 1Mbps up. There is nothing in particular that I will be doing at the moment it just suddenly dies.Things I have done that have not worked.I have changed my channel to 1,6,and 11.Updated firmware.Factory Reset (New broadcast name/password).Set up static IPs.I have tried disabling WMM Support and this just kills any connection wirelessly to the router.Is there anything else you can think of to fix the issue, or should I just be demanding a new router the next time they come

Region : Malaysia
Model : TL-WDR4300
Hardware Version : V1
Firmware Version : TL-WDR4300_V1_121226(Unifi)
ISP : Unifi
Recently my router have been experiencing an issue with internet connectivity with Unifi.I will be able to connect to Unifi, the status is "Connected". However after some time though, like 5 - 10 mins, I will be no longer able to browser any pages or get disconnected from online games. Checking through ping tests, I can see that I am unable to get a response. Checking the router shows that I am still connected to Unifi. After a minute or so the connectivity is restored, but the issue happens again as before. This happens with both wireless and cable. Attached is a sample of the ping test result.
Things I have tried:
Updating the firmware to the latest version
Re-configuring the modem
Re-setting the Unif credentials in the router
Downgrading the firmware

I have a brand new DAP-1522 A1 connected to an 802.11n wireless LAN in bridge mode. Running in the 2.4GHz band with WPK-2 and AES security/encryption.Everything runs fine 99% of the time, but once a day or so the wireless LAN connection on the DAP-1522 drops and then takes about two minutes to re-connect. It re-connects and then everything is fine for a day or so until the next dropped wireless connection episode on the DAP-1522. I know my 802.11n wireless network is 100% fine as during the dropped connection to the DAP-1522 I can connect directly to the 802.11n wireless network (running from my gateway/router) using my other computer, no issues.I've seen some posts on this forum that the A1 version of the DAP-1522 hardware is not 100% compatible with the 802.11n network standard and there will be intermittent wireless drops. If this is true, it's just insane. All I can say is I can't believe DLink would allow a product to be sold that won't work properly on 802.11n networks.I check the logs each time I see the dropped wireless connection and all that shows is the following.1) Negotiating connection 2) 4-way handshake success [mac address]There's no message in the logs about why the wireless connection dropped, but I assume it has something to do with re-newing a key for the wireless network as the successful key renewal messages are the only other messages in the log. When the wireless network dropped I don't see the successful key renewal message at the time I should see it.I thought this DAP-1522 would take 15 minutes to configure in bridge mode and then I'd forget about it. Spend too much time on this already, so a bit disappointed with this DAP-1522 and DLink tech support....though when it's connected to the 802.11n wireless LAN it works fine.

I recently upgraded my Linksys wrt120n router firmware & had to reconfigure settings. Subsequently, some (but not all) of my apple devices are having intermittent wireless connection problems. Specifically, my ipad1 & ipad2 never lose their connection but a mac book pro (~ 2 years old), iPhone 3g, iPhone 4, older iPod touch & very old i book g4 all work for a period of time (usually 1/2 day) & then lose their connection. When I attempt to reconnect these devices I receive the following error..."unable to join the network xxxxxx....". I also have a Dell laptop (1 1/2 yrs old) that generally does not have the connection problem. Finally, when the devices do lose their network connection all I have to do to reconnect is go to the Linkys router setup webpage & click on save & the wireless connection works again (almost like this is just refreshing the connection for these specific apple devices). I was not having any problem prior to the firmware upgrade & from what I have read the older firmware version is no longer available so going back to the old firmware does not appear to be an option.

I have a user that uses an ASA 5505 in NEM to have his/her laptop and Cisco IP Phone at home. The ASA 5505 establishes a tunnel to an ASA 5510, which is connected and speaking EIGRP to our core switch. Off of the core switch we have our CCM cluster.
The issue happens on the first call after a long period of no calls. After if happens on the first call, he/she can continue to make calls without the issue. I though it was a timeout issue, but his/her ASA configuration is the exact same. Also, he/she is using the same group policy, tunnel-group etc. as everyone else with the same setup.
This issue happens regardless if she has a PC behind the phone or not.Internal calls and external are both affected.
I am aware that most one-audio issues are RTP connectivity issues between the two endpoints. I can clearly see in the routing table of all of our routers, that the route to the subnet her phone is on has not changed for days, and she has had the issue within that amount of time.
I'm looking for a good place to start troubleshooting that doesn't require me to to a pcap. If all else fails, I will do a pcap.

I am running an 877W in the home that for the most part works fine, however after being connected for a variable amount of time I partially loose my DSL connection. Line sync stays up, but the traffic is lost.
A shut/no sut of the atm or dialer interfaces does not resolve the issue, only a reload or power down/up will fix the prob short term till it happens again.
Am currently running advipservicesk9-mz.151-3.T1, but have also rolled back to advipservicesk9-mz.124-24.T5 which has the same issue. Have tried a 857W with the same results. So ruling out IOS and hardware, its pointing to a config issue. It has also only been an issue since changing from ADSL1 to ADSL2+.
interface ATM0
no ip address
no shutdown
no atm ilmi-keepalive
exit

I've tries some changes mentioned here and from other sites, but no success yet...

I have reason to be suspicious as to the game's relevance. These spikes are characterized by no packet loss, as measured by pingplotter and winmtr (more specifically, there is packet loss, but I've come to understand that because it does not continue on to subsequent jumps it's not an issue), and latency leaping to between 250 and 600ms across multiple hops, seemingly without pattern or form, for intervals
Here are some summaries of some extended pingplotter sessions. The suspicion that this is not entirely WoW related is recent, so I'm working on seeing if I can get similar results from some other sources.

Norton came with the laptop but I did not click on the button to activate it when it popped up on first opening3) A small strange thing: I get "SWMagent is restarting" message when I restart the computer.

I have had DSL service for several years from a small, local ISP, that pays Verizon for the use of their lines. On 1/2/2012 in mid-morning I began experiencing lack of connectivity. I noticed that the "link" light on my DSL modem was blinking. I tried turning everything off & starting up again but to no avail. In the morning, I turned everything on again & for about 45 minutes my DSL service was perfect. Then it became intermittent & mostly unavailable.
