Cisco Wireless :: AP 1602 Strange Hostnames For WiFi Clients

Jan 30, 2013

we want to replace our 1242 AP's with the 1602 model and so far everything works like a charm. We have just noticed, that most of the clients which are connected on the 5GHz N radio, the web interface of the AP1602 shows his own host name instead of the clients host name.
 
For example: 
Radio0-802.11N2.4GHz
SSID INTERN :
[code]..... 
 
The Host name of the 1602 is "AP-LABOR", so why it shows the own host name for the Dell E6420 Notebooks on the 5GHz radio and on some "NONE"?

Cisco Wireless :: WRV210 Strange Log And WiFi Drops And Reboot

Apr 13, 2013

I've a WRV210 Wireless-G VPN Router with RangeBooster, that logs this alert almost every time, "Packet type : 0 -- free socket buffer only".Also each time that some devices, like Android, are connected to the Wifi, the wifi starts a reboot and drop cycle.
 
Some extra context information, I've connected to the router a Cisco Gigabit switch and all the wired devices are connected to the switch, that could overload the router? Other point I've a Cisco VOIP gateway connected to the router and a few VPN's and firewall rules setup.

Strange Wifi / When Gaming Often Get A Lag Spike Every 10-20 Second?

Feb 23, 2012

My Wi-fi on my rig seems to have some odd problems. When I'm gaming i often get a lag spike every 10-20 second or so, and before I got the "Vista anti-lag" program I was also getting the enormous 60 second lag spike. I'm sure many Vista users recognize this problem. But here is the deal, the first kind of lag spikes completely disappear while talking on Skype! Which makes me wonder, what is it with Skype (only while talking) that removes the lag? Gaming with Skype makes all games run fluently without any spikes at all.

Cisco :: ASA-to-ASA VPN With Hostnames Instead Of IP Address?

Mar 8, 2011

I'm setting up a bunch of VPN tunnels for a customer of mine. Because we want the ability to fail over tunnels manually and to change IP addresses in the future without having to reconfigure both sides we want to build the VPN tunnels to hostnames instead of IP addresses.[CODE]

Linksys Wireless Router :: Maximum Wifi Clients On Wrt54gt?

Sep 20, 2012

I have a wrt54gt running firmware 1.0.04 in my house.  I have about 30-40 wifi devices.. Mostly smartphones connecting to the router.  If i look at the dhcp table there is about 35 computers listed.  The router is running on channel 2.
 
Lately ive noticed that certain devices can not connect after they are powered up.. It could be a tablet, pc or smartphone.  Most will error out saying they cant connect.  If i turn off a working device then the newly powered on device can connect.  It seems like i have reached a limit.
 
Setting a failing device to static ip does not work, the device never succesfully associates.  I tried upping the dhcp pool to 100 from 50. Is this just a limitation of the router?  Is there another router that i can buy that will work for me?

E4200 Version 2.0.37.131047 disconnects my wireless clients intermittently. I am seeing it mostly on the 5Ghz band but that is where most of my clients are connected. I have all the setting in advanced tweaked per cisco best practice. It just seems to reset every so often. Wired connection is not disconnected.

Linksys Wireless Router :: X3000 Some Wifi Clients Can't Discover Connection

Nov 23, 2012

I've just upgraded my home wireless from an NetComm NB5540 + modem to a LinkSys X3000.Internet access works fine for all devices, but some wireless devices can't "see" my Win7 desktop system that's on a wired connections to the router. Galaxy Note phone (running ICS 4.0.4) can discover and connect to file shares on my desktop system without any problems.Asus Transformer Prime tablet (running JellyBean 4.1.1) can see the router on the local network, but can't see my desktop. Even if I manually type in the IP address it can't connect to itLikewise my old WinXP laptop can see the router but can't see or connect to any other devices.
 
I tried connecting the NetComm router with just Wifi configured to one of the ethernet ports on the X3000, so I've got two Wifi networks running in parallel. If I connect to this second WiFi network with any of the above devices then they can all discover and connect to my desktop system on the wired connection to  the X3000.

Cisco :: Resolving Hostnames Via 2504 Controller

Nov 28, 2012

I've just installed a 2504, upgraded the firmware so that 3602i ap's can attach. As a test I left the network open and am running dhcp from the 3560 switch. Why am I unable to ping or connect to a device by name within the same subnet on the "wired" network? There's no DNS server.

Cisco Wireless :: Strange Power Failure With AIR-AP1231G

Mar 25, 2012

I'm having the following issue with a couple of 1231's.
 
Some overall config info first:
 
This is a small office with 2x Catalyst 2950 (24-port, no PoE) switches and 4 AP1231G (autonomous). The APs get PoE from a PWRINJ3 each. The injectors are powered by the AP power supplies. Injectors and power supplies are mounted in the patch closet.
 
The 2 switches are connected together over 4 ports (20-23 on each switch), these ports are set to 1Q Trunk mode.
 
The APs are connected to the switches, 2 to each switch, on port 1-2. These ports again are configured as 1Q Trunk.
 
APs are connected to the switch as follows:
 
   [switch] <- patch cable-> [injector] <- patch cable -> [patch panel] <- static cabling -> [outlet] <- patch cable -> [AP]
 
All this has been working without problems for a number of years.
 
A few weeks back, AP2 did not restart after a power cut (everything else did). All LEDs are off, port on switch has no LEDs lit. I did not get around to investigating this furtehr until last week. I unmounted (failed) AP2, took it to the spot where (working) AP3 hangs, and plugged it to the cable of AP3. AP2 came to life immediately. I unplugged it and plugged AP3 back in, which restarted immediately.
 
So I suspect a power supply issue on AP2. I took the injector and power supply that fed AP2 out of the patch closet. When connecting AP2 directly to the power supply, it came to life immediately. So I figure the injector is defective.
 
On the same day, I notice AP4 is also dead (again all LEDs off, no idea how long, could have been that day or could have been a few days - it has definitely been working after the power cut that appeared to have killed AP2).
 
So I order 2 new PWRINJ3s and for good measure 2 new power supplies. Later that day, I took the injector and power supply that fed AP4 out of the patch closet. When I try this combination (AP4, injector4 and P/S4), and connect it to a different wall outlet (and therefore a different port -16 - on the switch) IT WORKS! Should have triggered questions, but did not immediately.
 
Last Thursday I got the new injectors and power supplies. So I take one of each, hook them upto AP2 at my desk, and AP2 starts up. So I mount new injector2 and new P/S2 in the patch closet, put AP2 back in its place, connect all the cables - NOTHING. AP2 does not start. The "power" LED on the injecvtor lights up green, the "device status" LED remains off. I take AP2, new injector2 and new P/S2 to my desk, hook them upto a wall outlet (connected to switch port 17). AP2 starts immediately.
 
Meanwhile AP3 has (also) stopped working (no LEDs on at all). As far as I can tell, it stopped working after I briefly disconnected (and reconnected) the patch cable between injector3 and the patch panel in the patch closet. The LEDs on switch port 1 are off.
 
I have since tried to power cycle both switches (took power off both, waited a while, poewerd both back on). No change.
 
PS: the APs ran firmware 12.3(8)-JA until recently. AP1, AP3 and AP4 were upgraded to 12.3(8)-JEE after the the power cut that took AP2 out. THis is when I found out AP2 was dead. AP2 was still on 12.3(8)-JA. It was upgraded to 12.3(8)-JEE last week when it was on direct power on my desk.

Cisco Wireless :: Mesh LAP Strange Reload In WLC4402

Sep 1, 2011

Our costumers has implemented 2 AIR-WLC4402-50-K9 with Software Release 7.0.98.0, the wireless infrastructure consist in 2 Root-Mesh-LAP and 8 Mesh connect over-the-air to deploy outdoor coverage.

All the LAP are Aironet 1520 Series Mesh Access Points with equipped with 3 antennas for 2.4GHz and 1 antenna for 5GHz (backhaul).For one year all seems to be ok, yesterday after a power outage of one Mesh-Root-LAP, 5 Mesh-Lap continues reload each 10-12 minutes, on the WLC Log you can see event like a reboot from AP Console, on the LAP console i can capture this event before the reload:
 
Log on LAP Mesh
%DOT11-6-GEN_ERROR: Error on Dot11Radio0 - Not Beaconing for too long - Current 0 Last 0
%SYS-5-RELOAD: Reload requested by Dot11 driver. Reload Reason:

What does it mean? That the beacon signal trasmitted from Root-Mesh-LAP cannot reach the Mesh-Lap and so the Mesh-LAP force a reload?Where we should search the cause? In the power instability or in a interference on the 5GHz radio interface?
 
On one of mesh Lap I found a strange reason for a releoad:AP1780-Mesh uptime is 11 hours, 10 minutesSystem returned to ROM by power spike

Tp-link 300mbps Wireless :: Tl-wr941nd Ssid Is No Longer Visible In Wifi Clients

Apr 9, 2013

Region : Others
Model : TL-WR941ND
Hardware Version : V3
Firmware Version : 3.13.9 Build 120201 Rel.54965n

We are trying to use a TL-WR941ND purchased about a month ago, but it keeps hanging, usually within a day or so of operation.To be clear: by "hanging" I mean the device stops providing wireless services (its SSID is no longer visible in WiFi clients) and becomes nonresponsive to pings or control access attempts (via settings web page) from the internal network connections.The device is used in a very simple scenario, where it's being employed as a simple access point, not as a router. As such, the device's configuration is as follows:

* WAN interface is configured with a dummy static IP (10.10.10.10/24) with gateway and DNS set to the internal IP address of the actual routing device connected to the external world.
* LAN interface is configured with an IP address inside the actual internal IP subnet (192.168.1.0/24).
* DHCP is also disabled as this service is already provided.
* Wireless settings: radio enabled, SSID broadcast enabled, WDS disabled, 11bgn mixed mode, auto channel width, max TX rate, channel 7 (manually set). Using WPA-PSK security.

Rest of the settings are unchanged from their default values, as the device isn't being used as an IP router by any client - just as a WiFi/Ethernet layer 2 bridge. We're using what appears to be TP-Link's latest stock firmware for the device.The settings described above appear to provide the connectivity required by the WiFi clients. However, the device continuously hangs within a day or so of operation, requiring someone to physically attend to the device and cold-restarting it (disconnecting it from power and reconnecting it) to regain an operational state.

After performing a cold restart, the system log shows nothing beyond the startup entries: "System started" entry followed by security info entries regarding enabled protocols. Then the device appears to work well for a while, until it hangs again, forcing again someone to attend to the device, etc.

Linksys Cable / DSL :: X3000 - Able To Ping IPs But Not Hostnames

Oct 3, 2012

We have a brand new Linksys X3000, with the latest firmware installed.  It does not recognise the hostnames of devices on our network. We have added a few hostnames, using 'manually add client'.  My first question is why would it not recognise hostnames (a variety of devices, e.g. phones, apple time machine, linux PCs)?
 
The next problem is that that we are successfully able to ping IP addresses, but when we ping hostnames, results are inconsistent.  e.g. currently I have my laptop and a time machine connected by wire directly to the router.  I can ping the time machine by IP.  The first time I ping by hostname, it works, but immediately after that I ping again and it says 'unknown host'.  Why would it suddently forget about a device it is clearly connected to?  Have we got some sort of default security setting I don't know about?

Linksys Wireless Router :: DIR-615 Strange Download Speed

Nov 13, 2011

I have searched the forums, and can see that I am not the only one with speed problems on this router. When I changed from a D-link dir-615 (yeah, no wonder I changed it )  my download speed dropped from 4-5 MB/s to 1,3 MB/s. I'm using a wired connection. Have tried disabling QoS in router settings, did a firmware upgrade, reset the router. You see, when I do speed tests on the internet I get 40-50 mbits download, 25-30 mbits upload. I have tried many different files to download, both torrents and through my browser.

Tp-link Dual-band Wireless :: Wdr4300 Can't Able To Recognize System /all Wifi Clients Lose Connection

Jan 22, 2013

Region : Others
Model : TL-WDR4300
Hardware Version : V1
Firmware Version : 3.13.23 Build 121225 Rel.37950n
ISP : UPC Hungary Ltd.

I can't able to recognize a system - all wifi clients lose connection. When this happens, the ping answer time rech the ~2000 times, then totally lose the connection, the SSID is dissapear - checking with my phone (android - wifi analyzer) and TL-WN822N USB wifi adapter (with the inSSIDer application). Meanwhile the cable clients and the WAN connections works fine, didn't experience anything.If I restart the wifi service with the hardware on/off button, it runs well for some time.This problem appeared when I used the two older official firmware too.

I tried the auto-chanel function width auto channel width, tried to manually set up one of the less interfered channels with both 20MHz and 40MHz channel width, but none of them bring the solution.The intresting thing is, if I change the router with an old D-Link DI-604, the signal is weak, but the wifi connection is stable, with the same TL-WN822N adapter.I tried to guarantee the router, but after two weeks, my reseller said, it looks ok, they - at the TP-Link service - didn't find anything.

D-link Dir-655 :: Clients Lose Wifi Connection To It?

Jan 20, 2012

We are a small business with about 9 Macbook pros and 3 PC's connected wirelessly to the router. The Mac-computers sometimes lose their wifi-connection to the router. When this happens they have to select the wifi network again from the menu, to reestablish their internet connection. For some of the clients, this happens about once each day and for others multiple times a day. The problem doesn't seem to appear on the PC's.

I have tried to solve the problem by making DHCP reservations for each computers MAC-address, but with no luck. I also tried to set the 802.11 Mode to 'Mixed 802.11n and 802.11g', and turning WISH off. I read that the connection can be disturbed, if other wifi-networks in the area uses the same channel, so I changed it to channel 3, based on a scan of the network, where 3 appeared to be the least used. The WPA Mode is set to 'WPA-2 Only' and Cipher type is 'TKIP and AES'

The Dir-655 is hardware version B1 and the firmware is 2.0.

Cisco Switches :: Strange Network Standstill SG-300?

Dec 20, 2011

we have a production network that uses five SG300 switches that functions brilliantly most of the time. four of our switches run in layer 2 mode and the last switch runs in layer 3 as it is used to route our 7 vlans as well as routing traffic between our two gateways. the switches use the original firmware that shipped with the devices (v1 device) and will be upgraded within the next week.  the problem that we have is that the network seems to stop routing for all of the hosts after a given time. the only way to fix this issue usually is to reboot the main layer 3 switch. the main layer 3 uses a default route to one of the gateways and a return route has been applied in the gateway. the only thing i can think is that somewhere one of the devices routing tables become full and the network stops responding.

Strange Connecting / No Cable Detected

Apr 22, 2013

The issue that I am having is that the network cable I have that going from my router to my desktop computer, seems to be flaky, at least it seems that way...When I try to use the network cable that goes into this desktop, into another computer(one that I know works), the connection status alternates between connecting, and no network cable detected, connecting...and no network cable connected, and so forth.it NEVER connects. When I plug the cable back into the desktop, it does the same thing for maybe a minute, but then eventually connects. However, every other computer, laptop, macbook, another desktop PC, that I have tried connecting using this same cable never connects.

Strange HTTP Connectivity Hiccups?

Aug 13, 2011

My desktop PC has occasional hiccups in which I can't connect to any website (via any browser, I've tried Firefox, Chrome, Opera & IE) for short periods of time (usually ~1 minute) but all other Internet connectivity seems to be normal. (I can ping Google for instance, and I remain connected to Google Talk, but I can't load the Google website.)

I recently did a fresh install of XP Pro SP3 and am pretty confident that there is no malware running on the system. (I'm running Microsoft Security Essentials and Windows Firewall but I also did a Malware Bytes scan which uncovered nothing.) The desktop is connected wirelessly but I don't suspect an issue with the router because my laptop (via wireless) and my girlfriend's desktop (via wired) can surf the web just fine when my computer is experiencing issues.

I checked for proxies (both in the browser settings and in Windows settings) but everything appears to be setup correctly (that is, unproxied.) DNS is set to the proper DNS servers for my ISP (Cox) but I also tried switching to Google's DNS servers with no luck.

Strange Disconnection Only On Online Games

Jul 6, 2012

Basically I started disconnecting when I logged onto Blacklight Retribution after a recent game patch, after a few days the problem stopped and I was able to play again (with no changes to my computer) a few days later another patch was added and the problem occurred again, at first I thought it was a Blacklight specific problem (as this was my only installed game) however i installed a few other games (Kabold Online, Perfect World, Forsaken World, TF2, MW2 and C9) and I got the same problem on each of these games. I haven't been able to log onto a single Online game for more than 5 minutes, normally I'm disconnected at login, HOWEVER, my internet works completely fine in for everything else, i can browse the web, download game clients etc with no problem whatsoever.(Forgot to add, When i disconnect my LAN Cable mysteriously Unpluggs itself (according to computer) and a disable/enable in network manager reconnects it)

- Checked to see if drivers were up to date (they were)
- Rolled back NIC Driver (and put it back when this didn't work)
- Checked device manager for any problems with my NIC, (working as normal apparently)
- Tried setting my NIC to 100mbps Full Duplex
- Setting my power options to not interfere with NIC
- Had a DHCP error in my event logs so i set my gaming machine to a static IP
- Turned of UnUP, Turned on DMZ
- Turned off "Green Ethernet"
- I had other Errors in the form of a service stopping my NIC
- Phoned ISP, Everything is OK there end but they sent out a new router, but problem still occurs
- Noticed that a service was sending a stop control to my NIC, looked on forums for fixes and applied several of them
- Reformatted computer with old XP (switched from windows 7), updated, installed latest drivers etc and still same problem except now I don't get anything in event viewer when the problem occurs.

The only thing i haven't tried is replacing my NIC, but considering the internet works completely fine for everything but Online games I'm unsure how this could be the problem.

I have a ASA5505 and it has a vpn set up. The VPN user connects using the Cisco VPN client. They can connect fine (the get an ip address from the ASA), but they can't ping the asa or any clients on the network. Here is the running config:
 
Result of the command: "show running-config"
 
: Saved
:
ASA Version 7.2(4)
!
hostname ASA
domain-name default.domain.invalid
 
[code].....

what I need to add to get the vpn client to be able to ping the router and clients?

Cisco VPN :: 5520 / 5510 - Can VPN Clients Communicate With Other Dynamic Clients

Nov 5, 2012

We currently have an ASA 5520 communicating with 10 ASA 5510's, all on static outside addresses.  I was asked to add 5 additional 5510's on dynamic address.  All worked well in testing until it was decided that some of the dynamic clients needed to talk to each other.

My testing shows packets just dying in the 5520.
