Cisco Wireless :: WRVS4400N Don't Have Any IP Conflicts On Network
Jan 11, 2011
I am using a WRVS4400N as my primary router for a small office. I get the following message repeated over and over in my logs. This seems to happen for 2 or 3 days and then it will go away for about a week and then come back. What is causing this? The best I can tell I don't have any IP conflicts on the network and most of the time the network has very little traffic other than 2 or 3 computers surfing the web. [code]
I'm on the road traveling and am having trouble with receiving an ip conflict error message shortly after connecting my windows 7 laptop to this particular hotels wireless network. Shortly after connecting to the correct access point is when the msg appears. I've checked my wireless adapters IPv4 TCPIP properties and ensured Use DHCP is enabled and that IPv6 is disabled. I've done a release and renew on the address after connecting as well (ipconfig /release and renew)to still no avail. Oddly enough, my internet connection works great in the morning at this hotel but has this problem at night time. Are there any known issues with 7 or such a thing as a Windows 7 "unfriendly" wireless router? I don't have this problem at home on my Linksys wireless router. Works fine.
I use a wireless laptop and a wireless printer with no problems until my lodger's friend comes and connects to the network. That is when I lose printer connection and sometimes get the IP address conflict message. Obviously something to do with his laptop wireless connection
I just bought a Samsung BD-D5300 Blu-ray player that allows a bunch of networking options including wireless and wired. I was using the wired option when I came across some conflicts with my network using a Linksys WRT350N v1. The Samsung conflicted with the Linksys's DHCP server. The blu-ray player turns off automatically when inactive. It was causing conflicts with my iPad 2, MacBook Pro and Motorola Atrix android phone whenever it got assigned an IP address. When I reset the router and my cable modem, it wasn't assigned an address for awhile, which fixed things, but as soon as it got an address again, it was caused conflicts by being seen as a LAN by my router. When it wasn't receiving an address, it got the automatic private IP address of 169.x.x.x. When I removed the connection with my router, the conflicts disappeared and my computers were able to access my wifi again.
I need trouble-shooting wireless network connectivity issues that arose recently:We use a Comcast modem and two WRVS4400N's as wireless routers/wireless access points.We recently got our comcast service upgraded to 100/20 and also got rid of our static ip address. As a result (I think there must be a sort of causal relationship here, but I'm not sure what it is) we can no longer connect to the internet using our wireless networks. We can connect to the wireless network, but have "No Internet Access."
LAN subnet conflicts with WAN subnet. My router is d-link 825 and my cable modem is Cisco EPC-3825. Op system is W7. Everything worked great with an older cable modem (Cisco 3000).
We have a new 2911 that needs to be configured, unfortunately it's at a remote site. I had installed the following config: [code]
Now, I do get a dhcp ip on the G0/0 interface and I can ping it from my remote network and the local router as well as the local lan. The hands and eye guy is able to telnet from the local lan but I am unable to telnet from either my remote lan or the local router.The only error I receive is "connection refused by remote host". All lines are clear so I have no conflicts with multiple telnet sessions.
Im trying to configure a 7204 for radius login authentication, although the router is also configured with radius for VPN access. How can I configure it for both using 2 different raidus servers? the login via radius is working fine on another router, although that one is not doing VPN access so there's no conflict.
My config:
aaa group server radius RADIUS_AUTH server x.x.3.11 auth-port 1645 acct-port 1646 aaa authentication login networkaccess group radius local
[Code]....
For some reason, this does not work. I cannot access the router and authenticate via x.x.3.11 radius server. I think there's a conflict between the VPN and the login authentication but im unsure how to resolve this.
So I have an WRVS4400N V2 and just got a new laptop with an Intel 6230 Wifi card in it and have an odd problem.While the laptop is on battery power the network gets massive packet loss.
I don't know what to do.Laptop manufacture says its AP but AP worked fine with old laptop and works fine when laptop is on power and all other devices seem to be fine with the exception of my Xbox 360 that wont connect if I have it on WPA2 but I will post another thread for that.
I put just got a wrvs 4400N and when I replaced my old linksys router I can't access my network computers anymore. I'm I missing something or do I need to do some kind of setup?
I have a WRVS4400N router and have successfully connected via Quick VPN Client 1.3.0.3 from my laptop running XP. I can ping any IP on my network, I can access HTTP addresses and remote desktop (VNC) applications but I cannot map a network drive.
The network drive is on a PC running XP, I have tried mapping using the system name as well as the ip and neither work. There are no problems mapping the drive(s) when connected directly to the router LAN/WLAN.
I recently bought a new Cisco WRVS4400N router for our network which has 19 computers connected to a 24 port switch. We are currently using a D-Link router and are upgrading to the Cisco router. The problem I am having is as soon as I connect one of our servers or the 24 port switch to the Cisco router I can no longer access the internet or login on the network, I also cannot access the routers setup from either server. If I connect the router to just a stand alone computer I can access the setup and change things but as soon as I connect the server or 24 port switch everything dies (all lights are still green on the router though so everything is connected).
I work at a small private school that is going to implement about 20 ipads for classes. Students bring their ipods and iphones and are connecting to the existing unsecured wireless access points and are taking up the remaining IP addresses in the DHCP scope. I am running out of IP addresses and was wondering if I could set up a VLAN using the Cisco WRVS4400N for all of these wireless devices the students will be using. I plan to pull out all unsecured wireless AP's and replace with what ever solution we come up with. I will need about 6 access points/routers to cover the entire school. There is not a lot of money for technology and the ipods were donated. I have never set up a VLAN before. Is there an inexpensive way to allow the students with their personal ipads/ipods and the 20 ipads owned by the school to connect to a VLAN to keep from using up our DHCP IP addresses from the server.
I hardly try to get WDS running with two WRVS4400N v2.The manual (and the web interface) says: "Note: The WDS feature allows WRVS4400N to connect with up to 3 wireless repeaters that can be either WRVS4400N or WAP200." But I wasn't successful by now in getting it working..What I've done so far:
- Setup the primary WRVS as Gateway, WAN through Modem, LAN and WLAN using WPA2 Personal Mixed, DHCP - works perfect - Setup the second WRVS as Router using the same WLAN settings, no WAN and no DHCP - Enabling WDS on both WRVS, giving each the MAC address of the other - no connection to LAN or WAN through the second WRVS
I really need the second WRVS act like a bridge. Since the manual is saying that I can connect both devices through WDS I bought two of them. On the other hand I've now read somewhere in the community, that this isn't possible with two WRVS (?)
I've got an out of the box WRVS4400N and it will not pick up a DHCP IP from the ISP.
I reset to factory defaults, tried another ISP, returned and got a second wrvs4400n all the same results - no IP address on the WAN port. The internet LEDs are blinking but no IP on WAN port and no internet connection from a laptop connected to wrvs4400n.
I even tried turning of the firewall too.
Is there something with these routers that needs to be done for internet access?
Most typical small routers are just set up as a DHCP client on the WAN side and DHCP server on the LAN side.
In the note, i ve seen we can configure a WDS with 2 WRVS4400N, but i can't.How can i configure the 2nd WRVS4400N as repeater? Or can i configure it as Access point for another modem ?
I am having some problems with WRVS4400N v2.We use it just for wired network (wireless is not in use, but it is configured). As a WAN we use PPPoE. Most machines do not use DHCP.After a while (few hours to few days after power up) the router freezes and it is not accessible. I cannot ping it or access to the admin page.I have the latest firmware version (V1.00.09-ETSI)I also called service and they suggested to reset it to factory settings and reconfigure it.
I have an older Linksys WRVS4400N Version 1.1 VPN Router. I have it set to run in mixed mode G/N. I still can only get connection speeds of 54 Mbps though. How can I get my wireless N clients to see 300 Mbps speeds?
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 am have a lot of difficulty getting my WET610N to connect to my WRVS4400N. I have tried almost everything. I have some older PC's, as well as my PS3, that we use to use on the network and they only connect B/G. I have tried auto DHCP and static IP on the bridge. It seems that the only way that the bridge works is by using the WPS function that the business class routers do not have.
Now that Comcast is in the process of rolling out IPv^ to their customers nationwide, will there be a firmware update that properly displays the IPv6 /64 address as provided by the cable provider? Currently the only IPv6 address displayed is on the LAN page and is not configurable (greyed out) except for the prefix length. I already have a cable modem that will provide both IPv4 and IPv6 addresses as they are rolled out.
I have installed a WRVS4400N router in a client's office. When laptops are plugged into the router everything works fine. When they are attached via the wireless signal it drops frequently. WPA personal is being used to encrypt. I have also installed the latest firmware and am having the same results. What can be done to eliminate the drops?
I have an ongoing problem with my WRVS4400N router. It reboots on it's own when streaming video through a wireless connection (computer, xbox, roku, tv). Once I make a wired conection, it performs flawlessly. The firmware is up to date. I have read some reviews of this router on Amazon stating the same problem, but I expected it to be solved with firmware update. Unfortunately, this was not the case.
All of my remote sites use various routers to route all of their traffic via IPsec. However, I have one WRVS4400N w/firmware 2.0.2.1 configured with a working tunnel. My issue is I need to set the Remote Group to 0.0.0.0 0.0.0.0 so all traffic is forced via IPsec tunnel and not out the local gateway. When I do the error, Remote Security Group and Local Security Group cannot be in the same network. However, it works with Cisco/Linksys RV042.
I've been searching high and low and although I've found many results of people having this same exact problem there doesn't seem to be a fix, or at least no one was kind enough to post one. I have many vlans but the 3 in question are 10, 20, 30.
-10 is for my laptops and desktops with an ip range of 192.168.10.10 - 192.168.10.50. -20 is my home automation network with an orange of 192.168.20.20 - 192.168.20.150 -30 is my guest network with a orange of 192.168.30.84 - 192.168.30.89
I have a dell powerconnect configured with vlans as my core switch. I trunked a port on the switch assigning 3 vlans (10,20,30) and connected it to port 1 on the wrvs4400N. On the wrvs4400 I trunked port 1 tagging vlan 10,20,30. For some reason vlan 1 is untagged on port 1 and I don't know why. I also have a router connected to the powerconnect. Of the 3 vlans I mentioned vlan 10 and vlan 30 are the only ones with interfaces on the router. Vlan 20 is an internal network with a separate router and until I figure this out that router is physically turned off. Also the router currently turned on has no routes configured to connect my vlans. Currently there is no configured way to jump vlans.
No matter what ssid I connect to I get a dhcp response from vlan 10. all my test indicates that I'm actually on vlan 10. I get internet and I can hit all devices on vlan 10. If I connect to ssid guest and change my ip address to match vlan 30 I can not ping the gateway for vlan 30 and I have no internet access. Some times I get something different. Sometimes I get an ip address from vlan 1 on the powerconnect. If I renew my ip address then I'll grab one from vlan 10 but I should be getting one from 30 or none at all for vlan 20. The absolute crazy part is my droid sometimes gets a 192.168.4.x ip address. I don't have a 192.168.4.x network or dhcp scope anywhere on my network! If I physically plug into a port on the power connect I get to the correct network 10 out of 10 times. If I configure vlans on the other 3 ports on the wrvs4400 and physically plug in, I get to the correct network 10 out of 10 times. I've reset to factory a few times and I've been all inside and out of the wrvs4400. I have no clue what could be wrong with this thing.
I have setup a ISA2006 as Internet firewall, and use 4400N as VPN Client, connect to ISA2006 via IPSec VPN, but it did not work.
Network topological as below:
Internet <------------> ISA2006 <-------------------------> local1 <------------>local2 <--------------------> WRVS4400N <----------> PC Static Internet IP | 192.168.112.25 192.168.112.0/255 | 192.168.114.0/255
WRVS4400N v2.0 2.0.0.8 QuickVPN 1.4.1.2 Vista Home Premium SP2 64-bit
Trying to connect from laptop through an AP to my WRVS4400N via VPN. Not having much luck...I get to "Activating Policy..." and then "Connection Error".I like this router thus far, I have been able to set up multiple BSSIDs and VLANs which has been very useful.
I have several wired and wireless devices connected to the router which is running the latest firmware (2.0.2.1) and I have this issue with all wireless devices. The router is configured for B/G/N Mixed, Channel 6, and to broadcast the SSID. Security Mode is WPA2-Personal w/ key renewal set to 3600. Connection control is configured to allow only the desired MAC addresses. All wireless clients are configured for DHCP (as are some of the wired clients that do not have this issue). I have tried various setting changes over time, none of which have resolved the issue.
What I have determined, and may be useful, is that each time this occurs I am unable to ping the router from the client and have no connectivity to the internet or other devices on the network. If I ping the WAP address (reserved for internal use address) I get a response and then connectivity is always restored after doing so. In other words, I ping 192.168.1.1 and get no response, immediately ping 192.168.1.2 and get a response, then immediately ping 192.168.1.1 and now get a response and connectivity is restored. If I skip the first step and just ping the reserved address followed by the router address result is always the same. It would appear the issue is between the the two router addresses.
Prior to owning this router I had a Linksys BEFSX41 that I had for about 7-8 years and a WAP54G I had for about 5, both of which still worked and I never had this issue with my wireless clients. I went to this router for the increased performance and am very happy with that aspect, however this issue is unacceptable.
We have an office with about 10 PCs, and several other network devices (smartphones, printers, etc). Some PCs and printers are wired, some are not. About two weeks ago, some (6) of the wireless devices lost connectivity. Since then, some (4) of the devices have also recovered normal connectivity.
As of right now, there are two computers, a laptop and a desktop, that cannot use the wireless network. They see the wireless network, connect to it, receive an IP via DHCP properly, have correct DNS servers listed in ipconfig, but they can't ping the router, use the intranet, or internet.
I have a WRVS4400N that broadcasts two different SSIDs. One is a public network and the second is a private network. Right now, both SSIDs are pulling from the same DHCP server, but I would like to separate the public from the private. How can I separate these SSIDs by vlans? I can't seem to get the vlans to route to separate ports.
This is my vlan settings. I have two DHCP servers right now. One is in an isolated network plugged into Port 3 of the WRVS4400N. The other is on the production network, plugged into port 1 of the WRVS4400N. For some reason, whenever I connect to SSID Public, it won't pull an IP from the DHCP on port 1, it only pulls it from the one on port 2.
I know there is three SSIDs here, the Static one is going to be the same network as the EMS one.
