Cisco Wireless :: 5500 WLC Port Stop Transmission
May 24, 2012
i have a 5500 series WLC connected to a switch through a trunk port with 2 v WLClans. the connection works fine, but sometimes it loses connectivity. it works again rebooting the wlc.
When the problem presented, i checked the cpd neighbors on switch and it didn't show the wlc, and i checked the cdp neighbors on WLC and this shows the switch in its neighbors list. i also checked the port counters on WLC and the receiver counters keep increasing, but the transmission counters remains in the same value. then i can see that only the TX side on the controller is down, if i restart the WLC the problem disappear temporarily.
Is there a misconfiguration or a wlc bug related to this behavior?
The switch is a Catalyst 3560
The WLC controller code is 6.0.188.0

I am dropping a FIN packet in the server and sending the following request from the client
curl --local-port 56789 http://servername
At this point a session is created for the port no 56789.
Immediately ,(the port has not finished the transmission yet) , I am sending another request using the same port as following.
curl --local-port 56789 http://servername
Now the following error occurs .
curl: (7) bind failure: Address already in use
My question is how to reuse the same port (56789) again in this situation?

The coaxial"or any other metal cable" was using for transmission signals(before fiber optic) the coaxial need repeater every 2 or 3 Kilo meter,because the signal will be attenuation when pass through the cable,when we transmission electricity to far places ,we use transformer to rising the voltage to 10000 or 100000 volt

i want to use the browser statement "192.168.1.1:443" to access my gateway, instead of using "https://192.168.1.1", but my browser keeps translating this to "http://192.168.1.1:443"

I'm new at the ASA5500 domain. I have a question: How can I redirect traffic coming on a port to a machine inside the LAN listening to another port ? I would like to use ASDM.

Few days ago I faced a issue in which one of ours 4500 stopped providing poe on some ports in one line card. I called TAC and ran some diagnostics. However, there is a command that I found and it is NOT DOCUMENTED on 4500 reference guide! The command is "diagnostic monitor poe". This command actually detects/recover POE hardware failures! After executing this command, poe start to work again?

I have had trouble to verify the support wireless speed and band that CISCO891W-AGN-A-K9 supports. I saw on a vendor website that it supports a max wireless transmission speed of 54Mbps but this seems low for what is supposed to be the current model wireless router which is supports 802.11n. What the maximum supported wireless speed and whether 5Ghz is supported? Plus I am thinking about purchasing it for my home wireless network (upgrading from an 871W).

I've got an AIR-AP1142N-E-K9 access point, i've got the Radio0-802.11n(2.4ghz) enabled and the 5.0ghz disabled.
i've got my client real close to the AP and i only get a connection speed of 72Mbs.
Shouldn't i get 150mbs? Maybe some wrong configuration?

I'm trying to modify the power transmission control of multiple Lightweight Access Points (1131 AG E K9) at one single time on WLC 4400 or WCS.It is effectively possible to configure the power transmission per LAP and in global on WLC 4400 but i need to configure it per group of LAPs =i.e group X of 10 LAPs will have a power Threshold of X -dBm and group Y of 15 LAPs with Y -dBm.

I have had a DIR-655 for years, and this is a treat - channeling everything from IPTV, to a fast fiber connection, transfers - no sweats.
Then I had to setup a router for a friend, and recommended the DIR-615.
Setup the router, and max it would connect with was 150mb - I changed the settings accordingly: auto channel scan channel width: auto 20/40mhz
So this "opened" up the 300mb speed - however only for 5 mins, then it falls down to 150mb.
My laptop (lenovo) connects to the dir-655 just fine at full speed, and this is also the machine I used for testing the dir-615.
It's ax Hx firmware, FW: 8.04
What I can conclude by using inssider, and xirrus wifi inspector is that it generates 2 channels - and then after 5mins of connectivity looses a channel, and then the speed drops.
I got a new router from the dealer, same issue. Then a friend of mine lent me an ancient dir-615, and interestingly enough this had the same configuration option of "Transmission rate" in the wireless settings page! Just like the dir-655. and also connects at 300mb...

If I send video file(overall bit rate is 17.5Mbps) to client with 2.4Ghz band, it always freezes and go repeatedly around 1 second interval. the distance around 10m away without any wall, open space actually.
But same condition with above, cheaper wireless router no problem at all. It happens only with EA4500. And there are no any parameters setting menu actually.

the only way i can get 300mbps from this router is by having these settings, it seems the only valid settings to get 300mbps from the router are the following:
Network Mode: mixed
Channel Width: auto (20mhz or 40mhz)
Channel : 1
if i leave the channel to auto it won't show up as 300.on top of that it doesn't want to stay at 300mbps for very long, sometimes its max rate in inSSDer is only 144 or 156mbps. its the weirdest thing, i think this version of the firmware seems to forget to check for how fast its wireless transmit speed is.When it reboots it only transmits at 144 or 156mbps. i have to go in the basic wireless page and just save the settings to reset it to 300, i don't even have to change anything, it resets its max rated speed back up to 300mbps.and more importantly, are the devs aware of this problem for the e1200 v2 ?

I have been disappointed by the range of the EA4500 compared to previous routers, but I am most puzzled by it's behavior. I may get an "excellent" connection close to the router (one room away) and speeds up to 65 Mps, but after a few minutes of surfing the web the signal strength and speed can drop substantially.
The problem is the worst at a distance (one floor down in our house, maybe 30 feet away in total) where the signal strength may start at "good" and a speed of perhaps 30 Mps, but then after 3-4 minutes drops to "poor" and maybe 5 Mps.

I would like to connect my 1841 to the equipment that has RS-422 interface in order to transmit data. I have to buy one WIC-1T to support it. However, I am not sure that this module will be able to support RS-422 or not (As I can see there is DB25 which is the interface of RS-422, but I realize that RS-232 also has 25 pins.)

The LSRefreshtime is 30 minutes in OSPF as per rfc 2328, So the router LSA will start after this time(30 minutes). By using router lsa only the Link State Database will be updated. Suppose the datatransmission is started when it(router) is switched on. by using Link State Database only the routing table will be updated.

560km long pipeline, intermediate station at every 30 or 40 kms. Couple of Ip phones, 2 or 3 IP camera, and few control signls (IP system) will be connected at every stations. Do not expect heavy data. Which one may be the prefered economical solution can I use
1. Ethernet network (Switch with Optical SFP ports at every site)
2. SDH equipment at every site
3. DWDM equipment (if so lower end)

I recently bought the Dlink DIR-655 router and I have a Dlink DNS 323 nas. I have them connected and working. When I send data from my PC to the DNS 323, i'm doing about 6MB/s. when I'm sending data from DNS 323 to my PC, i'm doing about 30MB/s. all 3 devices have the 1000 Mbps enabled and Jumbo frames is enabled on the DNS 323 and my PC. is this normal?

For an N300 model F9K1002V4 router, how can I tell if it's transmitting in N mode? I have two newer laptops that are capable of receiving the 802.11N signal but are only receiving at 54mbps. The router is set to transmit at b/g/n rates.

Is is possible to run Transmission or Google Chrome only using OpenVPN? Other applications should use default connection (eth0) since I am connected to Intranet which won't be accessible if all traffic is routed through VPN. I am using Ubuntu 12.10 and some Premium VPN server (similar to HMS VPN)

1. Does Linksys WAG320N support USB printer? Can I connect a printer to USB-port and send some text to print from notebook via wi-fi?
2. The fact is that I have a cheap, simple chinese WiFi-ADSL-modem ZTE, which has 3 modes - low / medium / high for WI-FI signal. So, the signal is transmitted by ZTE at LOW-level is equivalent to signal, which now sends my WAG320N. When I turn ZTE on high-level, then the range of wi-fi signal increases much, comparing with the range given by WAG320N. So, where can I turn on high-mode in my WAG320N?

I have TWC internet, I've never had a problem till 6months ago. I play online video games often and well it was all fine and dandy. My brother use to have a desktop which he skyped 24/7 webcam and all, that didn't bother my gaming till he got a laptop. Now that hes on a laptop and only when using a laptop on wireless it makes my internet go crazy. I played wow and my ping was 110 once he got started in a webcam session it would fly up to 1000+ in ping. PS3 would lag to s---. I'm not exactly sure whats causing the horrible lag, I know the program that does it is Skype webcam when ran on wireless. Some people say they use you as a super nod whoring your net out to others. Others thing is too many incoming connections bottlenecking my router. Is there any way to fix solve this problem?. I lag even when QoS is set. He uses a Windows 7 Laptop.

I have two WAP4410Ns (about a month old) running 2.0.4.2. They both stop transmitting wireless traffic after about 2 days. The SSIDs (which are normally broadcasted) stop showing up and all wireless devices are disconnected. When accessing via the wired management interface, everything appears normal. No errors in the log, device is responsive, etc. If I reboot it through the Administration menu it reboots and goes back to working normally for about two days. This is happening with both my WAP4410Ns. As far as I can find, I am running the latest publicly available firmware.
