Cisco WAN :: Reconnection 819 Router After Connection Failure?

Dec 6, 2011

I have a Cisco 819 WAN Router (C819 Secure M2M GW (non-US) 3.7G HSPA+ R7 w/SMS/GPS).Software: Cisco IOS Software, C800 Software (C800-UNIVERSALK9-M), Version 15.2(2)T, RELEASE SOFTWARE (fc1)
 
For dialing in at my Provider (T-mobile Germany), I use the following chat-script:
 
chat-script gsm "" ATZ "" AT+CGDCONT=1 "OK" "AT!SCACT=1,1" TIMEOUT 60 "OK" "ATD*99#" "CONNECT"
 
Dial-In is successful after Reboot.Now, i want to simulate a conenction fault, e.g. termination by mobile provider.So I used the command "clear int cellular 0".After that, The router can't dial in again.
 
Debug shows:
 
Dec  7 11:04:03: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access1, changed state to down
Dec  7 11:04:14: CHAT3: Attempting async line dialer script
Dec  7 11:04:14: CHAT3: Dialing using Modem script: gsm & System script: none
Dec  7 11:04:14: CHAT3: process started
Dec  7 11:04:14: CHAT3: Asserting DTR

[code]...
 
Is the "clear interface cellular 0" the wrong way to test this, or why can't the Router reconnect?The only solution is a reboot, but that is not the best option. The router should automatically redial.

Linksys Wireless Router :: Wrt54g - Regular Wifi Connection Failure After Updating To 4.21.5?

Aug 26, 2012

I recently updated my WRT54G V3 to frimware 4.21.5 and now get regular wireless connection issues.  The wired connection never has any problem (can connect to the router and the internet), but none of the wireless devices can see either.
 
The problem happens every couple of days, and cycling the power seems to be the only fix. When the problem does occur, the wireless devices don't even see the broadcasted SSID.  But cycling the WRT54G's power fixes that.
 
I've gotten a few suggestions to do a "30-30-30" reset, but can't find exactly what that entails.

Wireless-n Wifi Repeater Connection Failure

Oct 28, 2012

I have recently purchased a Wireless-N repeater which is now up and running and connects with both Ipad, iPhone and other laptops with ease. The problem is that I can't connect using my own PC. I'm using Windows Vista and the connection to the repeater seems fine, it just can't connect to the Internet. Every time I try and open a web page I receive the following message.Error 105 (net:ERR_NAME_NOT_RESOLVED) Unable to resolve the servers DNS address.

Cisco Firewall :: Connection Failure In ASA 5520 Security Contexts

Mar 27, 2011

Ive got a virtualised firewall running 3 security contexts in routed mode. What am experiencing is that i cannot connect to an OUTSIDE host through the security contexts. From the firewall itself i cannot ping the directly attached host on the OUTSIDE interface but i can ping the directly attached host on the INSIDE interface. When i reload the firewall box, the first ping to the OUTSIDE host would be successful but subsequent pings fail and thus total connectivity is lost.
 
I even tried upgrading to ASA version 8.4(1) but still the same.

Cisco Application :: ACE4710 Troubleshooting Connection Failure From Client

I have a ACE4710 setup to load balance a couple of web servers. The real servers all show as inservice as do the propbes and serverfarms/virtual servers. If I ping the Virtuual server ip address I get a reply but it I try to access VIP via telnet or web browser. I get a connection could not be open error on the client.The question is how do i determine where the error is comming from so far I can not tell if the client is getting through the acl or not.I have used the trouble shooting guide and nothing has worked to determine the cause so far. show service-policy int479 detail does not show an increase in the hit count when I try to connect.show stats conn does not show an increase in failed or timed out connections when i try to connect.

Linksys Cable / DSL :: WAG120N / DIR 600 - Internet Connection Failure

Mar 23, 2012

I will just explain my setup:
 
I have a ADSL Huwavi modem by my ISP installed at my place.. Now the wireless from that device is very bad.. So I purchased WAG120N to setup a daisy-chain kind of setup in my other bedroom. I also put another D-link DIR-600 in between to give a connection to the first floor (via Ethernet cable).
 
So my huwavi is the ISP device, then a LAN from it goes to the dlink internet (WAN) port. then one cable from the d-link LAN port to the LAN1 of WAG120N and another upstairs.
 
Now all of this was working perfectly.. I put same SSIDs and Pwds on both ISP router and WAG120N and i was getting seamless net..
 
Now yesterday we removed the ISP modem to do some shifting.. Upon reconnecting, the ISP modem, Dlink work as before, but the WAG120N refuses to connect to the net.. it shows DSL down and doesn't access the www.
 
What I felt is that since i changed LAN ports on my ISP device and dlink, the static IP settings on the WAG120N should be changed.. i modified it, set to to point to the dlink for internet and huwavie for DHCP.. yet nothings happening..
 
I even connected the WAG120N directly to the Huwavie, yet it fails to connect to the net..

Linksys Wireless Adapters :: AE3000 Adapter Network Connection Failure

Feb 27, 2013

I just purchased 2 AE3000 adapters to update my wireless network and cannot get either of them to connect to my wireless network through either of two computers I tried. It hangs for a while looking for address and then I get the 'limited or no connection' note. But yet when I plug in my old AE1000 adapter into either computer I get connected right away. I've looked under the device manager and it shows up there, the LED lights come on and I see my wireless network show up on available networks. I am using the windows wireless manager in lieu of the Linksys one and as such I don't think any specific drivers are being used. I bought two updated adapters to start with is to keep current and NOT have problems.

Linksys Wireless-n E1200 New Router Setup Failure

Jan 19, 2012

I have been attempting to set up a linksys wireless-n e1200 router on my hp p6-2007c (Windows 7 SP1, 64-bit) desktop pc for the last day and have exhausted everything i can think of. The previous router was a linksys WRT54G and it worked fine. However, upon setting up this new router i get a "no internet access" message accompanied by the little yellow triangle and the ability to still connect to my router via its ip address to alter its configuration. The connection status for the network and the internet is identical for all the laptops in my house. I originally attempted setting up the router using Cisco's setup program. At its conclusion, the setup program informs me that i am connected to the router, but my internet connection has been lost (even though it was never there) I have tried starting over from scratch by resetting the router back to its default settings and using a variety of different channels (Auto, 1, 6, and 11), frequencies, etc. I have uninstalled norton antivirus, disarmed the windows security programs, made sure of TCP/IP settings, rolled back, uninstalled, and finally updated firmware, uninstalled/reinstalled driver for wireless card, disabled/enabled the card itself, deleted all other previous network profiles still present in the "Manage Wireless Networks" screen, and probably some other suggestions i came across in this forum. They all failed with the same results, i.e. the ability to connect to the network locally and having no internet access.

Linksys Cable / DSL :: WAG120N Wireless Router Hardware Failure?

Apr 29, 2011

I have been using it since approx 6months ago. Previously it was working well except for some major signal issues. However, 3 days ago it decided to go haywire. 1) It does not connect to the internet 2) It does not detect/connect to the computer when LAN cable is plugged in (does not load in 192.168.1.1) 3) I have tried resetting the router many times and even holding the reset button for 30 secs and switching off and switching on but to no avail. 4) I have had a linksys live chat with Johnel and he determined that it may be a possible hardware problem 5) Current Status of the Router: It makes no attempt to establish any connection/load whenever turned on, as seen when no lights are blinking when switched on. Upon switching on, Power Light becomes Red and Internet Light becomes Red and the middle Refresh Button become Red. 6) I have tried installing the driver for the router but there is no way I can install the driver because the computer does not detect that the router is connected What can I do about these? 1) Can I get a replacement of a different model? This router has been giving me problems since Day 1 2) I am seriously considering switching my service provider from M1 to Starhub. If that is the case, is there any way I can be replaced with a Cable Modem instead of ADSL Modem?

Cisco WAN :: 2821 MS Group Policy Failure / ICMP Size Too Small On Router?

Nov 29, 2010

When you use Group Policy to determine whether a link is fast or slow, fast links may be incorrectly flagged as slow links.
 
This problem may occur when a network that you are trying to detect a slow link to is configured to control the size and flow of Internet Control Message Protocol (ICMP) packets. For example, if a router allows for only ICMP ping packets that have a size of 1,024 bytes, the slow-link detection feature may flag the connection as a slow link. This is because the router discards ICMP packets that are larger than 1,024 bytes. If the router discards the packet because it exceeds the allowed size, fast links may be reported as slow links.
 
According to Microsoft, the default ICMP ping packet size of 2048 is used.Microsoft recommends changing every single Windows machine's ICMP size...but my customer would rather just change the router. It is a 2821 router, running 12.4(24)T4, using MLPPP to bundle two T1s.

Linksys Wireless Router :: E4200v2 - Bizarre WPA2 Authentication Failure

May 3, 2012

Just installed 2 E4200v2's for a customer today.  Was very optimistic because they worked great in my lab, both for my Win7 laptop  a MacBook.  And after installing 1 on-site and testing w/ my laptop, it worked fine.BUT problems arose when I installed both at the same time (I don't think I ever did this in the lab) and then I tested some computers.  Every computer that I tested (except mine of course), cannot authenticate correctly using the WPA2 password.
 
For the Mac's they get the error "The wi-fi network... requires a WPA2 password" then after entering the *correct* pswd, it says "Invalid password".  They're a Mac shop, but I did try one other Win laptop and that also had a problem, and the error was something like "security mismatch" although I was rushed and didn't write it down.

Linksys Wireless Router :: E2500 Linux Debian 6 (Squeeze) DHCP Failure

Nov 17, 2012

I have a Cisco/Linksys E2500 router. I connected to it through one of the Ethernet ports with a Microsoft Windows XP Pro machine and installed and ran the setup software. Windows was able to connect to the router and to the internet through the Siemens Gigaset 4300 DSL modem to my internet provider, Windstream.I cannot get my Dell GX620 which is running Linux Debian 6 (Squeeze) to connect to the router through the Ethernet ports.It appears that I receive no reply to the DHCP requests made by Linux.
 
I have only one monitor, keyboard and mouse and no KVM switch to run both the machines at once. I do have Windows XP Pro running in a VirtualBox virtual machine on the Debian machine,I can configure Debian to a static IP if I knew all of the IP configuration that the E2500 would assign. I would also need to know what reconfiguration the router requires if I use a static IP.

Linksys Wireless Router :: E1000 - Hardware Failure / Power Light On Continuously

I have a ~3 month old e1000 v2. In the last 24 hours it appears to have died, all 4 ethernet lights plus the power light and the one to it's left are on continuously. Before I dispose of it, does anyone know if this really is a hardware fail or is there some way to recover it? I've tried a few resets, power cycles and leaving it off for a few hours in the hopes that would bring it back to life but to no avail.

As you may have noticed even though it is matching an access service that allows Priv15. That doesn't seem to be passing through as you can see on top I am only receiving Priv 1. What can I do to properly pass through the access service profile?

Random DNS Look-up Failure

Jan 27, 2013

Whenever I try to open multiple sites, I will get a DNS lookup failure. Whenever I torrent something, websites give me a DNS lookup failure. Watch Youtube and open anoter site, DNS lookup failure. It seems that when I try to use too much internet I crash something... which doesn't make any sense because this problem has only come up recently. The only thing that I can think of is that I was messing around with the DNS to be able to connect to the American Netflix (I'm Canadian). I was using a site called "ZenOK" I believe, which gives you a server to connect to, and then a week later tells you it's no longer free (which they didn't mention in the signup)... so I removed the DNS number in my internet protocols, but I still get American Netflix.
