I have a brand new C1921 with EHWIC-4G-LTE-G using Vodafone to build an internet connection. First I did the setup like shown in the config guides and got the internet connection, but it was unstable.
Then I found some issues with the old LTE- card firmware in the support forum. Following that hint, I did an IOS upgrade to 15.2(4)M3 and the LTE- card update to Modem Firmware Version = SWI9200X_03.05.19.04. Post-checks after the update were all fine.
After that, I reconfigured the router again meeting the config guides. Establishing the internet connection, I get an IP address on the cellular profile, but it's not bound to the cellular interface.
sh cellular 0/0/0 profile Profile password Encryption level: 7
Profile 1 = ACTIVE*--------PDP Type = IPv4PDP address = 10.25.124.59Access Point Name (APN) =Authentication = None Username:Password: 05 Primary DNS address = 139.7.30.125 Secondary DNS address = 139.7.30.126
[code]......
Before the upgrade the IP- address was bound to the cellular0/0/0 interface and I was able to reach the internet.
Traffic Generator TG connected to R1 via switch SW . One end of the R1 is LAN1 interface and other end is WAN1. LAN1 is connected to switch SW. WAN1 is connected to R2 WAN0 interface..
Wen I pass traffic say 5000 from TG, I'm to recieve 5000 at R1 lan1 interface but I'm not to recieve at R2 WAN1 interface and hence not to R2 WAN0 interface.
Config at TG:' ----------------- Destination IP : R2 WAN interfavce IP Destination MAC : R1 LAN mac
I'm currently trying to set up a new infrasturcture with PEAP.
So, i've got redundant CA routers (c1921), an ACS server and 1262 AP's. Everything is working fine and as i want it to.Certificates are autoenrolled and so on, but if the CA root certificate expires, how to tell the AP to get the new root CA cert.
The root-certs are made by auto-rollover, and rolled on the CA router, but I got no change to get this root-cert on the AP.Is there a way to get them in an automated way, like rollover or enrollment?
I observed that when I was trying to troubleshoot a field issue using two routers I had in the lab, that one of them (an ancient C3620) did not like the PIMv2 Hello messages sent to it by the newer one (C1921).
The symptom observed with multicast routing is that when a source connected to the C1921 tries to register with an RP running on the C3620, the multicast route stays in the "registering" state forever. But going "the other way" - with the source connected to the C3620 and the RP running on the C1921 worked fine.
what I see in the C1921 when it tried to register a connection to the group 224.0.0.39 (for Auto-RP). Note: The two routers are connected via a GRE tunnel. [code] PIM debugging on the C3620 showed the following when the two exchanged. [code]
I believe that the issue is down to the firmware in the C3620 simply being too old and not understanding the PIM options defined in RFC3973 or the Cisco private PIM option 65004 being sent by the C1921 (though the PIM debug does not make it clear whether it is just the unknown options that are ignored or the whole Hello message)
Is there any global or interface-specific PIM option I can use in the C1921 to "dumb down" the Hello message so that the old C3620 accepts it?
I am running two ADSL lines into one C1921 router with 2 ADSLoPOTS cards installed.If I copy the firmware flash file on to the router (adsl_alc_20190.bin) and reboot, only one card shows the new firmware (slot 0).So sh dsl int atm 0/0/0 shows new firmware but sh dsl int atm 0/1/0 shows no change.How do I upgrade them both?
C1921, running version 15.1(4)M2, with licence for "IP base" feature set only.Trying to pass multicast via a PPTP VPN from a Windows XP machine to work around a non multicast-aware WAN link
1. With the IP Base feature set I am able to create a plain PPTP VPN without any encryption; the Windows XP machine can bring it up and unicast data passes through it OK in both directions.
2. But when trying to send multicast, only one-way traffic is observed:i. Windows XP host on far end of PPTP VPN and a local PC both running old Microsoft tool "MPING.EXE", sending and listening for traffic on the groiup 225.100.101.102i. The distant host receives and echoes back the packets received from the local machine + sending its own (confirmed with Wireshark running at the far end)ii. But the local machine directly connected to the C1921 router does not hear any packets from the far end; Wireshark shows only the ones it is sending.
3. Group status ("show ip igmp membership") as far as the C1921 is concerned shows both ends (192.168.50.10 (local end) and 192.168.50.201 (distant end via the PPTP VPN)) joined to the group [code]
4. But "show ip mroute" for that group shows an error; for the source on the far end of the PPTP VPN (having the IP address 192.168.50.201), the source interface is incorrectly shown as GigabitEthernet0/0 (should be Virtual-Access2.1 for that PPTP VPN) and the outgoing interface is shown as Virtual-Access2.1 [code]
5. I have tried adding static mroutes and messing about with parameters for the virtual-template interface for the PPTP VPN, but the problem remains. And if I put another local PC onto a different Ethernet port of the router, the multicast traffic does flow both ways - so the issue is solely with the PPTP VPN.After a week of head-scratching I am getting more and more convinced that it's a bug... but wonder if it is already-known, has a workaround, or a fix in newer firmware?
I just bought a "DLink Xtreme N Gigabit Router DIR-655" I configured it correctly. It works well for the wireless connection but my Lan connection (wired connection) does not work. The Lan computer connects to the router but cannot access the internet. All of my machines work OK with a Netgear G router, including the Lan computer.
I have problem with my Internet connection. Recently my Internet connection often get slow. There are 3 connections on the server running Windows Server 2003. 1st is External, 2nd is Internal and 3rd is VPN (please see attahement). There is nothing to do with External and Internal connections, and everytime the Internet connection get slow, I have to disconnection VPN (connection) and connect it again.
Every time I boot up my computer, everything will be working fine for about 5 -10 minutes, but after this, all my browsers will lose connection to the Internet. All of them: IE, firefox, chrome, even the steam browser, all of them just lose connection.The weird thing is, my net connection is perfectly fine: I can still play online games, still use online chat services, still open and use programs like utorrent. It's like something is just blocking all my browser connections.When I run a network troubleshooter, it says "your computer appears to be correctly configured, but the device or resource (Microsoft Corporation: Software, Smartphones, Online, Games, Cloud Computing, IT Business Technology, Downloads) is not responding."I googled this and came across some apparent fixes like flushing and re-registering my dns and restarting my modem, niether of which has worked.In addition, this problem is showing up on two totally separate shared networks and has only affected my computer. Other netwworked devices, like friends/families computers and my iPhone (which I am using to type this) work fine.
My hp laptop will no longer connect to the internet thru both a wifi connection or cable connection. I've also tried to do a system restore to an earlier date and it will not let mme do this either
I have a desktop computer that I have used for years and it has always worked just fine. We have AT&T (DSL, not cable) and it used to connect just fine but then I moved out, left everything plugged in exactly as it was and when I came back it wouldn't connect.It connects to the LAN but not to the internet. When I go in cmd to type ipconfig the DNS suffix is blank on that computer but says gateway.2wire.net on my wireless laptop. I eventually disabled UPnP on it because that's what alot of people were saying fixed the problem but it didn't fix anything. All it did was make the Internet Gateway Connection box disappear.Originally it was plugged in like so: Cable from wall > Cable Box > PC Now it is hooked up like this: Data cable from wall > DSL > Router > PC It stopped working BEFORE it was switched to DSL so that isn't the problem The DSL we have is "AT&T 2701HG-B 2Wire Wireless Gateway DSL Router Modem" and the Router it is plugged into that goes to my PC is a Linksys Wireless Router Model WRT54GS The PC is Windows XP Home, SP2?
I have recently installed SDM in order to access the internet with my 837 ADSL. I have configured the router's ethernet interface with ip address 10.10.10.1/24 (Default Gateway) and my PC to 10.10.10.2/24, I can both ping & telnet to the router from my PC, I also have pinged 8.8.8.8 on the router and that came up to 100%. But I am not getting the internet, I will show any configs from the router & post these for further information.
I nedd some Details for configuring the new internet connection from ISP.
I Will discribe the Curent network structre . We have a internet conection from one vendor That is comming to our router. we are using Cisco router 2600 that having two Ethernet ports.One port occupaid with connection from ISP ,One port going to ASA firewall.
We have a site site VPN conction with client between our ASA and thier ASA.
Now we need to configure one New internet Connection from another vendor .We need to use this new connection mainly for VPN.And once this connection is down we need to backup with old Connection.
how we will take the connection to the firewall or do we need to configure the new router.we have a new router.
Case: My home has few laptops and mobile phones connected wireless to the home's Router -> & to cable modem.
Problem: When I turn-on this particular HP's PC and connect to the internet (wireless) - the whole house internet connection becomes intermittent (e.g. OFF / ON). The Internet connection is fine (no problem), if this PC is not connected to the Internet (not connected to ie or google).
Trouble Shoot (without success)
- I have reformatted the PC and scan the PC with Malware in safe mode (no infection).
Ive been having a problem for the past few days that seems to be "unfixable" ,When I googled for it I found somone on this forum had the same problem , but none of the solutions that were listed were able to work for me. ( virus , restore comp , process causing it )The topic im talking about is 2wire Ethernet Light Blinking -Very- Rapidly + other problemsIm having the same exact problem as this guy and have the same modem. The internet will go down , and come back up in like 20seconds or so. Also at times I will experience heavy heavy lag. What I noticed is when the internet goes down , the Ethernet light stops blinking and is turned off , once the light turns green , it starts working again.his problem occures on all the comps in my house , some hooked up via wire and some wireless
I recently moved into a new place and my internet's been very spotty at best. The internet seems very fast at times but slows down, and even completely stop working, at other times. The weird thing is that my computer never says I'm disconnected from the internet. Instead, I either get disconnected from my games or the webpages I try to load show that it "cannot be displayed." The place I moved into provides wall jacks for a T-1 internet connection. I've tried directly connecting the ethernet cable to my desktop/laptop as well as connecting it to a router and trying out the wireless, all to no avail. The problem only seems to be resonating from where I'm currently living, as when I go onto campus, the wireless is fine.Also tried turning off firewalls, using a different browser, resetting the router, and a new ethernet cable.
I have a desktop that had issues, so I cleaned the hard disk and reinstalled the software like when it was new. I have updated all the windows and network card updates.When I first start the computer, I can connect to the internet for about 2-5 minutes then lose the connection. Often, internet explorer shows a screen that says the site is busy and try again later, but we can connect fine on other computers. Our internet connection comes from a DSL modem to a Cisco Valet Plus wireless router, however this computer is connected by a hard wire to a port on the router. I have changed ports, but have the same issue. The computers connected wirelessly stay connected.
I can restart the computer and the internet will work for 2-5 minutes again, but then do the same. If I go to ipconfig and release and renew, it still will not connect to the internet.
The other day I got a new Combo Modem/Wireless Router. I hooked it up and installed it as per Comcast's instructions. I have a Desktop PC running XP and a Laptop PC running Windows 7.I cannot get an internet connection up on either PC, although I am showing a Good Connection Signal on both my PC's.Called Comcast Tech and he pinged and said connection was good on THEIR end, and that Problem was on my end.I'm running Internet Explorer as my Browser on each PC.
Probably something easy but my brains are fried.Background :A network has about 6 machines connected to it with no internet connection3 machines connected to wireless router which has internet.Forsome reason, the machines that have both network connections, use the wired connection to access internet no matter what.When I disable the wired connection, it uses the wireless internet connection.How do I run both networks without disabling any, but tell the machines to use the wireless connection when needed to access internet?
My PC can pick up my and connect to my wireless network but i still can't use the internet. This has just happened randomly, i haven't changed anything in my entire setup. There is a Laptop, an xbox and another Desktop along with an ipod and ipad that are all functioning properly whilst being connected to the same network. I also have an xbox in my room next my PC which is having the same issue, it picks up xbox live but nothing works. Perhaps the issues are connected or share a common problem? either way it has left me stumped .I've power cycled multiple times, uninstalled and reinstalled my wireless receiver a even tryed using a brand new one. I called telstra (my isp) and they said they can't do anything because the receiver i use is not from telstra. I can use a wired connection fine its just the wireless, however it needs to stay wireless as i'm on the 2nd story of my house and my modem is on the first story. here are my results from ipconfig /all. [code]
I have my router connected to my ISP, but for some reason I am getting really slow internet connection compared to a home Linksys router. I can only think it may be to the fact my port is set to auto speed and auto duplex.
Sometime the websites are fast, other times slow. Cannot seem to pinpoint the reason since my code is so basic.
Basically I have 3 networks in the school - one of which I have no control over as it is a managed network. I also have a Microsoft Windows SBS network in the school which I look after myself. Both the managed network and what I class as my legacy network share a cisco router. The managed network is connected to wan port one and my 'legacy' network is connected to wan port 2. The cisco router has been set up in such a way by the managing company that the second wan port is for my legacy network and has an ip address of 10.127.40.1 and subnet 255.255.248.0 so my legacy network has IP ranging on the same subnet So far, everything works great in its current setup but I have now been given a task. The school canteen has had a Windows 2003 SBS server installed to operate their cashless system and I have been asked if they can get access to the internet. I could remove my 'legacy' network and connect their network but don't really wish to do so. This particular SBS server has been set up with ip addressing 192.x.x.x and subnet 255.255.255.0 Is there a way I can set up the two 'legacy' networks to 'share' this one internet connection. I need to keep the two legacy networks separate in terms of IP addressing. I also need to keep costs to a minimum. Minimum would be to disconnect my network but as I say, I don't wish to do so. I have access to some Cisco 2950G switches and I think from reading on the internet, that a layer 3 switch or router may be required?
I am having trouble with connecting to the Internet through the router. It has worked for 4 years now and all of a sudden it is not working at all. Any direction to getting reconnected. I have an Internet connection directly to the modem, and I can connect and log into the router admin panel, but it will not allow me to access the Internet through the router either wirelessly or by connecting directly to the router. All the lights come on and flash like normal and I have done a factory reset and still nothing.
We just moved to a new place and ISP here have a bit weried connection - they use cable modem that provides "local" IP (through DHCP) to the router and than you have to dial out L2TP to the ISP in order to connect to internet.This setup works fine with "home" routers, like the LinkSys, however I have no clue on how to setup it on 2811.
I have a D-Link DSL-320B ADSL2+ Ethernet modem that connects to the internet fine if I am using just 1 computer. However I have bought a Cisco WRVS4400N to enable me to get all of the other computers at home on the network (wired and wireless).
The WRVS4400N picks up a WAN address from the D-Link BUT I just cannot get an internet connection, just "Local" only. I have tried setting it up as a gateway, as a router, upgraded the firmware but it just is not having it. My previous experience with routers has been just to plug em in and let them get on with it. The WRVS4400N is proving very troublesome.
I have an ASA 5510 with a second internet connection on its way. I would like to have one internet connection dedicated to my Site-to-Site VPN traffic and the other left to handle public internet traffic. I know I can do this with a static route but I noticed today the "tunneled" option. How exactly does the tunneled option work and would it work better for my specific situation?
We just built a new shop and are trying to get wireless throughout the whole thing. However the situation is unique.
The internet connection is actually a large area wireless connection. It is provided by DTN. Basically we have a dish type of thing on top the shop that picks up internet from a transmitter about 3 miles away. There is a large cable that goes from the dish into a Cisco 350 Wireless card in the computer.

We are given a static IP address from the company which is in the 10.1.x.x range. What my original plan was to use ICS to share the DTN connection to a wireless router that is connected to the LAN port of the host computer. However ICS only works for the 192.168.0.1 ip address. We have to use the 10.1.x.x IP that we were given, that cannot be change. So because of this ICS does not seem like it will not work, unless there is a 3rd party tool that can used.
Also anytime that I enable the LAN port on the computer now that the router is plugged in, the internet drops off. it looks like the computer is defaulting to the LAN connection instead of teh DTN connection (which shows up as a wireless connection to XP). Is there anyway to stop this from happening?
Other notes: Computer: It is a Core2Duo running windows XP Pro.
Also are there any routers that can be purchased that can use a wireless connection input for the LAN connection?
Have an Inspiron 1150 laptop & have excellent wireless connection. Can receive email but IE will not connect. It connected fine in the past but I upgraded files and now it will not. I went to IE 8 but managed to remove it back to IE 6 but still no connection.
I get cut off after about an hour online. I have cable internet and they have been out to check. I have a new modem from the company. They have put the modem on a separate wire but the problem continues.
I've got a wireless connection in my house going through a Linksys WRT54GC router and also a wired connection with Cisco gateway (only 1 laptop uses it). About 1 month ago some strange things began to happen with the wireless connection, my PC seems not to be able to connect unless I reinstall the protocols and it's really annoying to do that every time I run my PC. Also, the wired connection stopped working (probably because of cable being broken) but it requires a router restart 90% of the time when I want to connect the laptop (that used to connect through cable) to the wireless network. The 2nd laptop has an issue mentioned in the title, the LAN works but it can't connect to the Internet through the router. Ipconfig /all shows that DHCP isn't working, there's no default gateway and DNS seems to be wrong. Could that all be related to router not being updated for a long time? I tried reinstalling drivers, unistalling and installing back network card and doing most of the things mentioned in similar threads but nothing seems to work.
how to do partition in internet connection?because when ever my brother uses net even if its only facebook i get lag i wanna know how to limit the net they can use for example our net has 10kbps i get the 6 the other pple connecting to my net get only 4 i connect to the lan they connect thru wifi
