One of SG200 interfaces is set as a Supplicant ant it authenticates in RADIUS (FreeRADIUS) server via C881 router. WinXP and other PC clients authenticate in RADIUS via SG200. Now: Authentication works perfectly. Ports open as they're supposed to. I'm able to reach RADIUS from SG200 and vice versa but there is a problem with WinXP. When i connect it to SG200 it authenticates, port opens and I'm able to reach RADIUS or any host on the left hand side but only for 300 seconds. After that period of time C881 looses WinXP from its ARP table and any communication fails. I cant even reach C881's interface facing SG200. Then i type:
I would like to implement simple QOS between two C881 Ethernet router.There are a GRE over IPSec Tunnel between both and 2 vlans configured on it (data & voice).The fa4 is connected to a modem, and a dialer is configured with the PPP account provided by the ISP.The DSL line is a 30 Megas bits download and 2 Megas bits upload.This is my config on one side (the other is the same with reversed) WITHOUT QOS CONFIG injected.
On our ASA5510 in the area AAA Server Groups, there is an entry for LDAP and an object that refers to our 2003 Domain Controller. This DC has LDAP over SSL enabled and I can see the DN and Password for a domain user account.I've created two new DC's, both R2 2008 but when I enable these in the same way it says it could not authenticate, ERROR auth server not responding, AAA group removed.I thought this had something to do with CA being installed on a DC, but it's not running as a service on the DC that was already referred to.
ACS had been integrated with Active Directory before ACS upgrade to 5.3. After the ACS 5.3 upgrade users aren’t able to login to AAA devices occasionally. Error message is:
24429 Could not establish connection with Active Directory
At the same time, when this issue occurs, ACS connection to AD works fine (checked with Users and Identity Stores> External Identity Stores > Active Directory “Test Connection”)
Last week, I was able to establish a site-to-site VPN tunnel between an ASA 5505 and Cisco C881 router just fine. The tunnel was up and and running for a number of days but today the tunnel is no longer up. I was wondering how, if there are any commands to re-establish or re-initiate the tunnel.
We have a network, with a MAC filter for the internet acces. Every body can just have one MAC adress entry on their name for internet acces . My idea was to give the MAC adress of another router(that i can control), plug the LAN cable in the WAN of the second router, and then connect more computers to that router. Would that enable Internet acces for all the computers behind the 2 router?would it work if i make one computer with an extra network card, register that computers MAC adress and forward internet by the second network card to a router or other computer?
The issue is occuring on our local LAN where my ARP requests are being modified after a period of time by the router for one host. I'm finding that the host will work fine with the correct MAC IP pairing for a period of time and then about 15-30 minutes later, the arp table is changing so the associated mac/IP address is now the mac address of the router interface.
The FastEthernet 0/1 port has no ip proxy-arp enabled and is set with ip nat inside.This only started happening after restarting the router, however the running config was saved as the startup config prior to the restart.I've tried hard-coding the entry with the command arp 10.15.4.190 c82a.1459.0579 ARPA however that is not working as expected.
The device is an 1841 ISR with the advanced IP Services bundle loaded. Is there some way that the router is viewing my host (provides DNS, Directory Services) as a intrustion attempt and somehow rejecting the packets?
I'm trying to change my wireless router from WRT54G which been using for more than 5 years to a WRT54GC which I got from my friend. I clone every entry from WRT54G to the new one, even MAC address. Below is what I captured from the old router WRT54G when it connected through PPPoE
Login Type : PPPoE Login Status : Connected IP Address : 114.91.200.128 Subnet Mask : 255.255.255.255 Default Gateway : 124.74.12.242 DNS 1 : 180.168.255.118 DNS 2 : 116.228.111.18 DNS 3 : MTU : 1492 from the web admin interface, I can ping and traceroute yahoo.com, so can I browse any website from my PC.

I just bought a E4200, is there a way change the default text of the pop up message that is used when the client is requested to put in the password to access the guest SID for the e4200?
I currently have a d-link DIR-615E3 with the latest dd-wrt firmware (v24 from 2010-12-13). Everything seems to be ok when I boot up the router - with factory settings and unsecured wireless, I have an internet connection. When I enter the GUI, create a router username/password, everything is still fine. Then, when I create a wireless security password (WPA2 personal) I lose internet connection, and the only way to get it back is to do a hard reset of the router. This also happens if I change any setting within the ddwrt interface, not just the wireless settings. (I also have a linksys WRT54GL with ddwrt with absolutely no problems) My cable modem is a motorola surfboard SB5101U, ISP is comcast cable, running windows 7.
AT&T Broadband ISP LanCity LC-PET3 cable modem (non DOCSIS) Linsys 4 port hub 2 Win98SE PCs All worked fine
New network is: Same as above, with a Linksys 1 port router (BFSR11) between the cable modem and the hub.
Router is configured to be a DHCP server (default configuration). I assigned the router a custom WAN side MAC to match one of my two PCs to avoid having to call AT&T to get things running.
Results: Everything runs perfectly fine initially, but after leaving and coming back to either system (left on, in standby) after quite a while (going to work / bed), the network connection is dead.
WINIPCFG still reports the same IP, but seems to hang forever if I attempt to release / renew. The router's is unreachable for configuration / status (it's still on the default IP of 192.168.1.1) Pressing the reset button on the back of the router restores the internet connection (quickly too - I'm back online in about 15 seconds).
Entering standby manually and coming back out again after just a couple minutes does not affect the internet connection - it seems to only occur when I'm off for an extended period of time. I have no had the time to determine what the period of time is, and if it is a fixed time since DHCP lease / initial startup, or if it is a fixed amount of inactivity time (or maybe even not a fixed amount of time at all).
When ever my roommates and I turn on or turn off a computer or device to log onto our wireless network that computer or device and all other computers or devices that are on the network lose internet connection for about 3 minutes. After that period then all devices gain access back. We have a Cisco Linksys router, Model number WRT110, it is the Range Plus version. I got it 6 months ago from a friend that had never pulled it out of the box or used it. I used it before moving and it did not have this problem. We are using cable for our internet and have a Motorola Surfboard model number SB5101U for our Modem. We have 2 Dell computers, both about a year old, and a LG blue ray device that connects wirelessly to stream movies
Using Vista Home Premium I've got a D-Link Dir628 router equipped with a USB printer port. All is well when it is working. However, at irregular intervals, the router and the printer do not communicate. The only way I can restore communication is to toggle the power on the router, then all is well until the next time this happens.
About a week ago my laptop started acting strange. I noticed when I brought my computer to my room (which is where i usually use my computer) it said that there were connections available where the signal bar is. Which is odd because it usually just auto connects. So i clicked on the signal bar and connected to my internet, but it lost the connection shortly after so I clicked connect again and it said windows was unable to connect to the router. Then shortly after that it said no connections were available. So i brought the computer to the computer to the family room ,where the router is, to check the router. It was nothing wrong with the router so I looked back at the computer and it was automatically connected to the internet with a five bar connection, but when i left the family room with the computer it immediately lost the signal. So i decided i should just stay in the family room. The next day the same problem occured and i went back to the family room to use the computer but i noticed the connection wasnt usually at five bars like it usually is wen im that close to the router but it was 4 bars or 3.
The next day i went over my fathers house for the weekend, and when im over there i pretty much always have a five bar connection even though im not in the same room as the router because im 1 floor directly above the router. Now when i used the computer over my dads house it had a 3 bar connection, disconnected from the internet at times, and when i try to connect bak it said that windows could not connect to router like it had said in my room bak at my own house, even though it always used to have a very high connection before this problem happened. So wen i got bak to my house i went to the family room to connect to the internet and now im having the same problems i had over my dads house. Now i try deleting some programs to see if they affected the internet and have even turned off some start off services on using mpconfig but that didnt work either
My laptop loses connection to the router.... constantly. When it disconnects I check my available networks and the laptop will not pick up any... neighbors or my own, I refresh they show up ...I have my network set as the preferred so it will always attempt to reconnect when available; Sometimes it starts to reconnect then drops off and cannot see available networks again! If I am able to reconnect... Sometimes I don't even have time to refresh my browser before it disconnects again; however sometimes I stay connected for hours at a time, other times/days just can't stay connected very long and becomes so frustrating that I just shut down the laptop and say "Fahgetaboutit"
I thought it was the network driver and a intel has an update(even though my LT doesn't show that I need it), I downloaded the update first knowing that I would be with out internet service after removing the old driver software but the new software installation always gives an error that it cannot install with older version present even after I'm sure I've removed it ... Not sure what to do... I ran cmd: ipconfig /all>network.txt&network.txt and here is the result of that straight from the activated notepad:
In EIGRP, if a router loses the successor to a route, and it has no FS, it goes active (starts asking all neighbors if they have a successor for that route).But if the neighbor did have a successor, shouldn't they have pro-actively told us about it when they learned it (so we already have it as the Feasible Successor?).
I have a Cisco 1841 Router with ADVANCE IPSERVICE IOS .The said router does not safe config, even after saving the config? As soon as the power cycled all the config will be lost? what can be done to correct this ?
I live out in the country at the end of a very long copper cable and my internet connection is never great at the best of times. Also live in an old house with thick walls so the family are always complaining about the poor wireless connection.So I bought a new router, netgear DGN3500, which on the whole seemed pretty good out of the box, but now it is randomly dropping the internet connection. Sometimes this is solved by rebooting the router, but just now this didn't do it and only turning it off completely for 30" and turning it back on again gave me back my connection (DownStream Connection Speed 3680 kbps, UpStream Connection Speed 416 kbps - which is as good as it gets on the end of my phone line).
Only at my home network, my HP Pavilion Laptop wifi will sporadically just stop identifying the router. The router (and Intel) shows enabled and good signal and my husband's laptop shows no interruption. My wifi keeps trying to reconnect but can't. I have to power off the router to reboot it so my wifi connects again. This is really annoying...
My dependable WRT160N started behaving oddly during last week.Suddenly without apparent cause, its whole configuration is restored to factory default by itself.I've noticed one week ago and last night when I lost my internet connection that the router changed its admin IP, login, ISP settings, Etc to factory default.I've used this router for almost 3 years or so with no problem at all. Always fast and easy.I'm using port forwarding, TZO account, NAS, protected WiFi settings, FW... Etc and is really annoying to rebuild everything once a week.
Several times a day our router will lose its connection to the internet (the internet light goes off, while the wireless signal stays on). All the computers in the house lose connection to the network while this happens. It will usually happen two or more times right after each other, so the computers can re-connect for a few seconds and then the connection will drop again. Eventually, after this repeats a few times, everything returns to normal.We've tried swapping cables, microfilters and 3 different routers (though all the same model). We tried the test socket, but the same problem happens. An engineer came to test the line but said he couldn't detect any problems. We have good download/upload speeds while the router stays connected and no noise on the phone line. I'm fed up of going in circles with the ISP tech support so I came here instead...One other thing I tried was OpenDNS, but that made no difference either...
Info: The router is a ZyXEL P-660HW-T1 v3... I've tried updating the firmware on it, but it wouldn't let me... If I remember correctly the Router Configuration Interface told me I don't have permission to do that.There are four computers connected.. mine is Windows 7, I'm pretty sure 2 others are as well, and also a Macbook... There's also various stuff like an Ipad, Kindle etc., which all lose connection at the same time.
It's about a Linksys WRT54G with Firmware: DD-WRT v23 SP2 (09/15/06) std it started resetting it's admin panel settings once every few months, lately it does that every few days, like name of LAN network, name encryption and password of the wireless AP, IP filter setting and so on
I have a 3COM cable modem and a WRT54GSV4 with v1.06.1 firmware for a home network. I have 2 desktop computers hardwired to the WRT54G and use 2 different laptops with internal wireless cards. All run Win XP Pro. I have spent numerous hours on the phone with Linksys support and always get the same response (reboot, unplug, reset, etc.)
I recently upgraded from a Linksys WRT54G2 that was a dream and gave me no problems at all to a Linksys E1000 that isn't behaving. Every hour or so it loses its PPPoE connection to the internet, so that both wired and wirelessly connected computers lose access. My laptop is also thrown entirely off the wireless network all together.
At home I have 3 computers and 2 mobile phones that connects to wifi network.Often, if I open up one of the computers that is sometimes off (laptop), then the network connection doesn't work anymore. I can still see the network in wifi choices on any device, but it won't connect to the Internet.
I have a problem with my E3200 that has happened at least 4 times since I first purchased, installed and configured it. Initially I thought it might be something with Comcast, but a) I never had the problem with my Linksys WRT54G router and b) It seems I can now duplicate the issue by saving a config file and restoring it.The specific issue appears to be somewhat random. At some point the connection to the Internet simply stops for no apparent reason. I am able to ping the router and connect to it. I am also able to drop and renew connections to the cable modem successfully. Furthermore, I can ping my network side of the router, as well as the external address handed to my router by the cable modem, and the cable modem gateway address, but still no connection to the Internet.The only solution to my problem has been to restore the factory defaults to the router and reconfigure it from scratch, which does seem to fix the issue for a time until it occurs again. FYI, I do not use the Cisco connect software because I have several custom port and QOS configs that are necessary for an IP Phone and other hardware on my network.
I've been using router for approximately three weeks with little to no problems and today the Paretnal Controls lost control. Anytime they were enabled they prohibited the associated computers from acessing the web even though the specific times was set to midnight -6am. Strangely, this has worked fine for three weeks and the only way I could get things back working correctly was to reboot the router. Just another firmware bug?
I have had my WRT310n for at least a year now. When I first started using it, my broadband speed would drop after a while till it was sometimes under 1mb. I have Charter high speed. I checked around here and found that heat may have been an issue so I got it propped up so I had some airflow under it even though it didn't feel hot when checking. I also updated the firmware then and for a long time it seemed to have cured the issue. Lately though, the problem is back. I updated firmware again but still no change. The unit is cool to the touch so heat is not the problem. After turning off for a bit and then rebooting, the speed goes back to normal and stays that way for a few days. I also tried rebooting my cable modem to test that aspect but after doing that, no change. Just rebooting the router fixes things. I'm at a loss. I can't keep having this happen especially since my wife works remotely from home.
No changes made but router will lose all information for IPv connectivity. I have paid twice to support to fix this issue and it still occurs every few months. I tried rebooting router, and doing an IP Release/ Renew and router does not get IP address.
