I still get the "security key mismatch error" for my school and home wifi. I know the passwords i'm using are correct.I also have the fake "Intel(R) Centrino(R) Wireless-N 6150" in my Device Manager. This does not have a driver nor can Device Manager find one.I recently noticed that there are 8 Virtual Wifi Miniport Adapters. What are these and why do they exist?

View 1 Replies View RelatedI had my computer in the shop for some relevant work - the system32 folder was corrupt.After this, i could not use any wifi networks. I have the correct password for two networks and get the "Network Security Key Mismatch" error whenever i try to connect.I cannot change the network settings in "manage wireless networks" because of:
1. a local wifi jammer
2. my adapter drivers not always working [URL]
3. the repairs done to my computer (i think... no networks show when the device is off and drivers working)
I also cannot alter the current router settings for either of the networks so resetting the password or "removing all wirless settings"
I have a 2wire router and can currently only connect to the internet with an ethernet cable. I've screwed my settings up trying to install my new router(WHOLE 'nother post lol!) Anyway it's not taking my Security Key..that I think is the right one. If I enter a different one it doesn't say incorrect, but it says possible security key mismatch or something like that.

View 5 Replies View RelatedI am just wondering on how mismatched MTU sizes are handled in Layer-2 networks and also inside a particular switches internal architecture.Layer 2 devices do not do fragmentation in the even of MTU mismatch. is this because Layer 2 devices do not re-write header information (like inserting destination IP and next hop MAC into the newly created frame.) i believe this is what they call per-hop behaviour? if this not the reason, then...? assuming this is the reason, let me proceed to my next question. When we set MTU on an interface , there is no mention of direction (ingress or egress), so i take this as means in both directions. so if a jumbo frame comes in on an interface which is set to recieve jumbo frames and forwarding decision is made and the frame is scheduled to egress via an interface whose MTU is not set for Jumbo frames, will the switch drope the frame at the egress buffer? if not, this implies MTU is an ingress property(only for incoming packets). But, again if it drops the packet, then MTU shoud have been system wide or global configuration as opposed to interface level configuration (just like nexus 5000).

I recently had some trouble with my ASA 5505 in that the running config would not be saved after a reboot. Definitely looked like a hardware problem with the flash memory. I have since bought a new flash memory card and copied the contents of the old card to the new card. 1st problem I have is that I can see the image on the new card, but for some reason it wont boot into that image. I get /file not found
I then successfully load a new image to the device and it boots successfully. I then follow it with a
Cisco asa# config t
Cisco(config)# boot system disk0:/asa831-k8.bin
(to ensure it boots from the flash in the future) and I get
WARNING: BOOT variable added, but unable to find disk0:/asa831-k8.bin
I have since tried
ciscoasa# fsck disk0:
Unsupported file system type!
%Error checking disk0: (No such file or directory)
When ever I try to do anything with Disk0: i get the same error. (No such file or directory). I have also tried putting the old flash card in the ASA and I now get the same response.

I have an ASA- 5585X (v.8.2.4) directly connected to an upstream 6509, which is running EIGRP. I configured the ASA for EIGRP with same AS# and network numbers and no auto-summary. Here are the log messages I got:

I lost my SSH connection to the upstream 6509 and couldn't get it back. Luckily I didn't lose my ASDM connection to the ASA, so I disabled EIGRP and went to look at the logs on the 6509.
What causes a K-value mismatch, and how to I rectify the situation?

View 1 Replies View RelatedWhen i'm trying to connect using stand-alone Anyconnect (not through the web), I got the SSL error message "The certificate you are viewing does not match the name of the site you are trying to view" (attached).
The certificate I installed for the SSL connection on outside interface got Subject CN=testvpn.mydomain and Subject Alternative Name (SAN) --> DNS Name = testvpn.mydomain
It seems to me that instead of connecting to testvpn.mydomain, anyconnect try to connect to the its IP address. I did try to remove the IP address in Server List in the profile, but it still doesn't work.
If I'm using Clientless (through browser), I don't received this error which means the certificates installed correctly.
Is that a bug on anyconnect 2.5.2019 or is there other ways to force anyconnect to check name instead of the IP against the certficate?

It is possible to detect situation when two neigbour routers involved in EIGRP routing are configured by mistake with different AS number ?I tried this situation practically. Two routers are connected together via Serial link network. One router has AS 1, other AS 10. I try to detect AS mismatch. First I check what EIGRP packet are comming debug ip packet detail show source <my neighbour IP address> destination 224.0.0.10 Ip protocol type 88. These packets are EIGRP Hello packet.
I try to go more deeply into details.debug eigrp packetsI see only ongoing EIGRP Hello packets. But I don't see any incoming packet from my neighbour (which has different AS number). It seems, because of different AS number router silently drop eigrp packet.Other debug eigrp command also doesn't show any info about AS difference.

We have some legacy Cisco 6513 switches with the backbone (16-port GBIC blade) MTU set to 1500. It has a WS-X6148A-GE-TX blade as well, MTU set to 9K.
Now we have a customer sending MTU of 1546, their copper interface terminating on WS-6148A keeps flapping. Does the flapping have something to do with the backbone set to 1500? We cant set the backbone to 9K at this moment since it may be intrusive (reuire a reboot).
[code] Can't find any wrong with the switch ports and AP's that can result in Duplex mismatch.The only difference I can find is the AP that is in all duplex missm. log's is used for other Mesh AP's to connect to.
View 8 Replies View RelatedI cannot seem to correct a duplex mismatch issue.I have a Cisco 2950 switch connected to a Cisco 2621 router. I am running a per-interface Vlan. I have two fastethernet ports and one NM-1E card installed on the router. One fastethernet port is connected to my gateway router, the second fastethernet port is connected to my switch for one Vlan. The NM-1E Ethernet card is being used for the second Vlan which consists of nine IP cameras. Though the cameras on the Vlan are working fine.Now, the NM-1E card is set to half-duplex. I know that I should be using a fastethernet module like a 1FE 2W or a 2FE 2W card, (which I have,) but the router does not recogonize either one of these cards when they are installed, and yes, they have been confirmed as good cards.
Using Router-on-a-Stick configuration is out due to the bandwidth contention besides the fact that the router I am using it on will not handle this due to the flash being an older version.I have forced the switchport to half duplex, setting the speed to 10. I was getting fewer error messages at first, but they soon increased back to the frequency that they began with.I have set the switchport to duplex auto, but this failed to resolve the issue.Obviously, I cannot force the switchport into duplex full since the NM-1E interface is set to half duplex. Can the NM-1E card be configured to full duplex? I can't seem to find any documentation showing where it can be forced to full duplex mode.Could nine IP cameras just be too much for both the router and switch to handle?
I have a 4503 switch (in L2 mode) running 12.1 hooked into a C2950 running 12.1, using regular 4 pair Cat5e cables to connect between them. The 4503 has Gigabit port 2/1 trunking to the 2950's Fa port 0/13.
When I set the duplex mode to DUPLEX FULL and SPEED to SPEED 100 on both switches (for their trunk ports) the link fails, and my 4503 loses connectivity (since it gets it from the 2950).
Here is my config from the switches (per description):
The 4503:
interface GigabitEthernet2/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,100-140

Note, this is the only mode that works (which seems to work fine, but I get TERRIBLE throughput for anything that goes over the 2950.
For guest clients , we have configured guest vlan and applied external web authenication on WLC 5508 , the session timeout value is 2700secons . When a client open a browser to internet page , wlc will redirect to URL and get the login page . After completed the login , he can go to internet page .

When performing an audit from NCS Prime 1.3 on our 5508 controllers (500 lic) we are getting mismatch messages from many of our 3602i AP's that say the following...
(Type)Configuration Name Audit Status Attribute Prime Infrastructure Value Controller Value
(AP APname, Interface) 802.11a/n Mismatch Spectrum Intelligence true false
These AP's are not configured as Spectrum Intelligence on the controllers, rather as local. It seems that NCS believes that they are supposed to be SI. We have refreshed the config from controller many times but this does not change. The 5508's run v.7.2.111.3 Is there a change I can make on NCS or otherwise to make this mismatch go away? Is this a bug? It is not causing any problems (that we can see) but as most would rather not have these mismatches.

I'm at a loss here because I know both images are valid. I've tested them both on my other 3560's.
