In one of my 2911's I have a VWIC3-4MFT-T1/E1 that terminates two pri circuit.s0/0/0:23 and s0/0/1:23 are in a trunk group. I've noticed that if the PRI flaps/bounces and comes back up, controller 0/0/1 and serial 0/0/1 stay down.Controller 0/0/0 and serial 0/0/0 always come back up. I have to restart the gateway everytime for 0/0/1 to come up. Thoughts? Interface config is below.

For about two years everything has been fine...no problems ever.About a month ago, I started getting timeouts and page not found errors when surfing the web, but my online games (EVE, WoW, etc) and our Xbox360/PS3 work fine. The only thing I could think was to unplug and plug back the DIR-655. Sometimes that works for a day or a week, but ultimately it always comes back. Is there a setting on the router I can change to avoid this, or a software command I can issue from the computer to clear something?

View 2 Replies View RelatedI have an MPLS router that connects to the core network.This router distributes (per route maps) routes from OSPF into BGP and from BGP into OSPF.The OSPF Process conencts a 6509 to the 7206 MPLS router. There are some routes in the OSPF process that I have filtered out of the 6509. They do not show up inthe 6509 at all and this is the only way they can be getting into the 7206.Checking the 6509 database, this route is gone, but it stays in the 7206 until I clear the route manually. The result is the route still gets distributed into MPLS. [code]
One thing to note, there are two possible OSPF paths the route gets into OSPF, one of them, the route is filtered with distribute-list on the 6509, which means it is still in the database, so it is still in the 7206 database, and still get distributed into BGP on the 7206, correct?
I might fancy having my desktop stay in a sleep state, waking whenever I need to access it for a file or something, so I tried to use WOL. The nic and bios support it, however when I enable it...
The machine only stays off off for 5-10 seconds at a time. I think this is because instead of waking from only a magic packet, it is waking from ANY packet.

Issue: Working on the internet, my computer (LAN) disconnects, Laptop (WAN) disconnects, but the router does not disconnect. The light that shows connection to net flashes like crazy (showing ADHD *** activity), the network lights just stay stable (showing no activity).After 5-10 minutes the problem sometimes fixes itself, or, more likely, I unplug the router, wait 2 minutes, plug it back in. Sometimes it works right away, sometimes it takes a second unplug.My computer is wired to the router which connects to a modem. The modem is not mine, its installed by my ISP.
Failed attempts to fix:Replace router. Bought brand new Netgear (will put numbers in here later) to replace the Dir-825.Same issues.In fear of malware, spyware, etc (I run a tight ship on my computer, I love it dearly and I'm mildly paranoid), I formatted the SSD, reinstalled Windows 7 64bit. Same issues.My ISP has to authorize every connection, so I've used the router to use my Mac Address and I can connect with the cable directly in the back of the computer, or to the router
I've a Cisco 5550 which hangs on powering up and stays at " Booting System, please wait..." forever and it has a flashing green Status LED.
The steps I've taken so far are:
1. Consoled with a different computer and tried to send the break signals (didn't work)
2. Open up the unit tried to remove the RAM's and reseated them again.
3. Taken out the CMOS battery on the board and replaced it with the new one (no luck still)
What is the next step, or shall I assume that the unit is dead.
I have an Asus U31JG with WIndows 7 64-bit. This laptop is a month old to me and the wireless has been acting up since the day I got it, will explain below. I believe my home network is the problem. I have a Linksys WRT54G with WPA Personal encryption. Multiple times a day my internet quits working even though Windows says it has full connection to my router. To fix this, I open command prompt and use "ipconfig /release" and "ipconfig /renew". This fixes the problem for me, it may be a minute or a few hours. The problem is very intermittent and only happens at my home which is why I believe it is my network. However, I changed the wireless channel to 1, the only one around on that channel and tried different security settings. My WiFi works flawlessly if I take my laptop to my friends house where he has a Netgear router. I have also tried a brand new Cisco Router as well as a Netgear router at my house.
I've re installed the driver twice, and the same problem persists in Linux only I just have to disable/enable wireless.
Note: When the internet quits working on my laptop it works on other devices so it is not the internet connection causing this. And my internet is very slow when it is working on my laptop via wireless.
My DIR-825 stays on even when I flick the power switch, for as long as I don't disconnect the externally powered Belkin USB hub from it. Some lights do come off, Internet light turns orange, but it stays on. If I disconnect the hub before trying to shut down the router, it turns off instantly.
I feel slightly worried by this because as far as I am aware, a USB client device shouldn't be feeding power to the host. On the other hand, the host shouldn't be accepting power from the client either.
Also, sometimes after days since last reboot, the USB light on the router is not on despite connected devices, and they may or may not appear in Shareport.
I'm trying to hook up a dap-1522 to an SMC8014WG wireless router. All goes well for about 10 minutes then the SMC drops all wireless connections except the connection to the 1522, and loses internet connectivity.There are several other wireless devices connected to the SMC but none of them causes it to go down.

I have at least 20 items that connect wirelessly to this router (2 PCs, 2 Laptops, 2 Tivo Box, 3 Game Consoles, 3 Cell Phones, 2 Tablets, 2 TVs, Printer, AP Gateway, and some other projects) It's been a solid connection to everything for the past couple of years.
I bought a new Dell Inspiron 15r SE laptop (uses the Intel Centrion Wireless-N 2230 Wifi Solution.) After anywhere from 2 - 10 mins of browsing/watching a video/downloading files the access out to the internet simply stops.
At this point I'm still connected wirelessly to the router, and if I go to the router address I still have access and can login and see the router settings. I check and there's plenty of time left on the lease (days.) Still not getting internet access. Eventually my Laptop will disconnect and reconnect (or I do it manually.) I've performed hard resets of the router, I've had my laptop Forget the network and then reconnect, etc. Nothing has resolved it.
I thought it may be my laptop, but I've taken it to Starbuck, Work, Neighbors WiFi, etc and I don't have any problems staying connected on their networks.
I've had Dell on the line, we connected hardwired, and there solution was to force forget and reconnect to the router, which worked for the 10min he was on the line with me, but then failed soon after, and back in the same connectivity hell
What do I do if my routers light stays amber and wont turn blue? The wifi is not working because of this even though it is saying the signal strength is excellent and I have already done the reset a bunch of times its been two days and I just cant get it to work. Its the N300 router

I did some testing with a few wireless N routers and then decided to buy a Linksys e 2500 as it was on a special for $66 in Australia.The wireless routers i tested were (Belkin brand new model / Netcomm & Dlink Used ones)1. Netcomm N800n Fastest wireless transfer speed 9MBytes or 72 MBPS.2. Dlink - Around 6MBytes/s or 48MBPS.3. Belkin - Around 4-5 MBytes/secDid not test the Linksys before buying it.4. Linksys E 2500 - around 5MBytes/s = 40MBPS.After all this testing, got a new Linksys believing that a cisco device should have good quality.My problems is that the connection speed on the device stays a 72BPS whereas on the Netcomm / D-link it used to be 130mbps. Not that this bothers me, however the file transfer speed matches the Link status connection speed.The router was placed at exactly the same location, file transfer was checked by transferring large file sizes.Lan setup is1. Belkin ADSL 2+ (Modem with Wireless b/g and Voip) only being used now as an ADSL Modem and VOIP service.2. Cisco linksys e 2500.3. Media centre PC which has a wired connection to linksys e 2500.4. Main PC (Connected wireless to the linksys). The network adapter is a DLINK DWA125 N150 adapter (2.4GHZ only). The distance between the wireless adapter and the wireless router is approximately 12 feet and there is direct line of sight.5. IPAD.5. Using 2.4GHZ as i dont have a 5GHZ adapter yet. Router is only on wireless N mode.I was better off using a second hand Netcomm rather than a brand new Cisco router. The cisco router has 4 internal antennas, whereas the netcomm one had only 2 external antennas. My signal strength is excellent. Only problem is the slow internal transfer between the Main PC and the Media Center PC. Main PC is Core i7 950 where as the Media Centre is a Core 2 Duo e6400GHZ with 4GB Ram. Both PCs running Windows 7 Ultimate (Main PC) , Professional (Media Centre PC). My network knowledge is decent. Is there any settings in the advanced Wireless mode for the Linksys that can make my internal file transfers faster. [code]
View 4 Replies View RelatedI know that the 3600 series APs are not supported on the 4404 WLC. However, would the following scenario be supported? I would like to use the 4404 (software rel. 7.0) as a guest anchor with a 5508 (software release 7.2) as the foreign controller supporting series 3600 APs. I ask because the APs do not need to join the guest anchor.

View 1 Replies View RelatedI am looking to configure a wired and wireless guest network. I have industrial barcode scanners that connect to one SSID and then there is the business network on the office SSID (no vlan seperation for these devices just different SSIDs). There is not really a need to seperate the business network from the scanners in any case. However, there are needs for a guest network and this needs to be seperated. At the bare minumum I would like to have the wireless guest network. Here is what I have: 2125 Wireless LAN controller managing 18 LAPs (1 indoor and 17 outdoors)Cisco Cat 2950 switches (2 x 24 port and soon to be replaced with 2 x 48 port 2960's with 802.1x capability) Sonicwall TZ210 firewallOne existing wired and trunked vlan for PLC infrastructure. One ESXi hosting Windows server guests (soon to be 2 with vMotion) The reason for the wired guest access network is tp prevent anyone from plugging into the wall jack in the office with thier home laptops or anyone else from being on the same subnet as our domain machines. Granted they would be unathenticaed but there would be no layer 2 seperation and that is what I think would be best.
How would I go about doing this on the wireless controller without an anchor controller just using my existing hardware? I would like to have the Guest SSID only availible in the front office. Is it possible to offer a guest network while still servicing the business network SSID on the same access point? Then might I be able to have the guest network be treated as it should at the controller? However this might present another issue altogether as the guest traffic will be over the same wire as the business SSID until it hits the controller for management.
We relocated several servers to our DMZ and, without a domain controller in the DMZ (we plan to put a RODC in the DMZ later when we mvoe to Windows Server 2008), i punch through the standard recommended TCP ports. ports 88,135, 389, 53, etc.) to the internal network located DC. I am double hopping to the DC (I hope thast doesn't matter) as the DMZ located web server communicates to another IP address in the same DMZ network and then I NAT that address to the internal IP address of the DC. Everything seems to be working for the servers we moved to the DMZ but i think i don't have all the necessary TCP/UDP ports punched through because we have found that logging into the DMZ servers is taking an extended amount of time, sitting on the “applying settings” screen. For 2-34 minutes. Also, we noticed that our applciations fols have to now add the fully qualified domain names when making calls to servers that just needed the domain name. When i open the access-list up completely without opening specific TCP/UDP ports, the issue is resolved.
View 4 Replies View RelatedI have a wireless controller that works perfect but because we have some new access-points 1602i that is only supported bij software version 7.4.100.0. So I need to upgrade the controller because I now have version 7.0.116.0. I have read in release notes of version 7.4.100.0 that I first need to upgrade to 7.0.240.0 to avoid losing those VLAN settings.
Note If you have VLAN support and VLAN mappings defined on H-REAP access points and are currently using a 7.0.x controller software release that is prior to 7.0.240.0, we recommend that you upgrade to the 7.0.240.0 release and then upgrade to 7.4.100.0 to avoid losing those VLAN settings.
But I also read something about Field Upgrade Software. If you are using a Cisco 2500 Series controller and you intend to use the Application Visibility and Control (AVC) and Net Flow protocol features, you must install Wireless LAN Controller Field Upgrade Software for Release 1.8.0.0-FUS. This is not required if you are using other controller hardware models. For more information, see [URL] .....
