Cisco Routers :: WRVS4400N Latency On Pings And Wireless Drops
Jan 21, 2012
I've just purchased WRVS4400N VPN router and installed it. This was a replacement of a old Linksys router. After installing the router, I've started seeing wireless drops, packet drops and latency on pings. I've installed the latest firmware, disabled Firewall services, disabled IPS. No changes at all. As a basic example, I am pinging my NAS device (hard wired to router) from a laptop connected to wireless below. Previously while connected to my old linksys router the time was equal to no more than 2ms.
I have a WRVS4400N router in a remote office. I have connectivity to the office and computers there. But the web interface for the router is failing to come up. This happens once every few days or so. Is there any utility or something that I can use to remotely reset the router without making use of the webinterface or having physical access to the router?
For eight months we have not had any problems with our new WRVS4400N (V2.0.2.1) connected to a Verizon/Westell 6500 to provide DSL internet for our network with DHCP on our server... No changes have been made to the router or modem since initial setup; but, then it started -- Our internet connection would drop intermittently. Sometimes every 5 or 10 minutes - sometimes every hour. Verizon has tested the lines which came up ok, then they sent a tech who changed the wire pair coming into the building for the DSL line and retested the lines which again came up ok, then they provided us with a new modem (now a Verizon/Westell 7500). After all that, the DSL still connects then disconnects intermittently. I am now wondering if the issue lies with the WRVS4400N.
I have two 1410 bridges installed in a point to point link using external directional antennas. The distance between the bridges is only 200M. As you can see below from the output the RSSI and SNR are excellent with a good fade margin available. These stats are almost identical to what my path profile calculated out to be. During normal operation the latency on this link sub 2ms, during certain conditions the latency jumps to 40+ms and starts dropping packets. I say certain conditions because we have not been able to pinpoint it. Unfortunately at this time the customer does not have the ability to do any SNMP polling or collect any statistical information (working on getting this setup). There are an excessive number of data retries and am not sure if that is normal. During the issues I have observered the below command output and the numbers did not change, which leads to me believe that it is not a RF issue. It almost looks like it's serialization delay, but I have no data to back that up. During iperf performance testing of this wireless link I could push 54Mbps of UDP traffic no problem, no errors, no CRC's.
Bridge Parameters Encryption: WPA-PSK w/TKIP Distance parameter: Configured to 1
I have a new WRVS4400N configured with a site to site VPN to connect to my office. At the office, we're running a Cisco PIX 515E. I have successfully established an IKE preshared key and the tunnel is listed as Up. I can successfully connect through the VPN tunnel into the office network through the tunnel and all seems good. After some period of time, the tunnel apparently goes into a bad state. Access to the office network is no longer available. When looking at the VPN status screen, the Linksys indicates that the tunnel is up. However, I cannot ping any resources on the office lan. If I disconnect and connect the site to site VPN tunnel, it connects and comes back up successfully. It seems like there is some sort of timeout taking place here. I am running the 1.1.03 firmware.
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.
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."
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.
What would be an acceptable number of wireless connections to a WRVS4400N router? I'm working in the IT department for a new company, and one of the offices complains that using VoIP and doing large file transfers are constantly a problem. They are all connecting wirelessly to the WRVS4400N. I managed to vpn in and connect to the web interface of the router, and it shows that there are 30 devices connected wirelessly to it. However, when people plug into the wall jack VoIP and data seem to work fine.I can't find any info on what a best practice would be for number of wireless connections to the router. There's no Vlans setup on it from what I can tell, so that may be my next step, to separate data and voice traffic.
I recently purchased a WRVS4400N security router and have got a strange problem with it. I set it up as my main router and connected two computers (a desktop and a server) using DHCP. They both work fine, internet is as fast as it should be, no problems whatsoever. However, when I setup the Wifi SSID (whatever security options I use, same with open/wpa/wpa2) and connect my laptop to it. It is allocated a IP address and windows even says that there is an internet connection. As soon as I try to do anything though, I am dropped. Try to ping an outside server, failure and dropped. Open IE, failure and dropped. I cannot even access my local server connected by wire to the router.If I connect the laptop via a cable to the router everything works, and it continues to work when I unplug it. So this means that right now I walk over to the router and plug my laptop in for 3 seconds before I unplug it and then use the wifi for a couple of hours without any problem. But as soon as I try to turn on my wireless Logitech SqueezeBox or wireless printer, they fail and take my laptop with it..
I have:reset the router, used both firmware 2.0.2.1 and 2.0.1.3 and done a factory reset.Tried to move the router close to the laptop, no difference.
I see a lots of problem associated with wirless connectivity with WRVS4400N, with following config
Firmware version - Firmware Version: V1.1.13 Wireless connectivity - G/N Mixed Auth - WPA2 AES Everything else default and AUTO,
Problem:The end devices suddenly drop connection. Wired connection works just fine. The DROPPED device can not be reconnected. On MAC I get AUTH time out. I see the SSID being broadcasted from my HTC wireless analyster so radio may not be the problem. I changed to set the speed to G only or N only but not avail. ONLY way to recover from this is rebooting the router.
Query regarding the Cisco WRVS4400N and Valet M10 routers. How to block the web interface (router login page) from wireless accessibility?
-Our Business is a hotel, so untrusted intruders are our guests. -Our ISP seeks hotspot methods that we cannot implement. -Our only solution is routers and an AP to extend internet wirelessly.
the login page or configuration page of the router is always accessible via the gateway address.if the gateway is 192.168.1.1, then a guest can just enter this address and try to guess the password. hacking tools add to the problem.the LAN is working but it is not of certification standards.I seek a way to block wireless access to the gateway login page or physical access only.
When clients connect wirelessly to the WRVS4400N they successfully get a DHCP address from the Windows 2008 server. After they have the address they can no longer access the server. It cannot be pinged, no drives can be mapped and internet access fails because the same server is running DNS. The WRVS4400N is setup for DCHP relay to the server. Wired clients do not have this problem. Wireless clients that connect to a secondary WAP on the same LAN also do not experience this problem. I have updated the router to the latest firmware version, reset it to factory defaults and reconfigured from scratch. Turning the server firewall off has not made any difference either. I have been able to bypass the internet problem by adding a second external DNS server in the DHCP scope options.
Is it possible to telnet into the 'WRVS4400N Wireless-N Gigabit Security Router with VPN' router? When I try it says the remote system refused the connection.
Basically my sister, who lives in a flat attached to the side of my parents' house, wanted me to find a solution for her to get internet, as there is no signal from my parents' wireless down in the flat.Originally I tried an old belkin wireless range extender I had lying around but even then the signal was extremely weak and the connection was too slow.So, I decided I would get some powerline adapters. But, of course, my sister needs wireless, so I figured I would use the powerlines to connect a second wireless router to the existing one.And so begin my real problems. The thing is, it actually worked fine at first. I set up a new wireless network, and had the ethernet from the powerline running in to the WAN port of the second router. But, every few minutes or so the connection would just die suddenly and take a while to come back (the connection was still there, but the browser just gave DNS errors etc).So I did some googling and fount a lot of people saying that I had to A) plug it into one of the LAN ports, not WAN, and B) disable DHCP on the second router.However when I do this I simply cant load anything at all. I'm thinking maybe there's some additional setup regarding static IPs or something that I need to do when I disable DHCP?
Right out of the box, the WRVS4400N [firmware v2.0.1.3] I just purchased says the WAN interface is DOWN; and it simply will not obtain an IP address from the Arris TM602G cable modem it is attached to. Internet still runs great on the old WRT54G. Is this WRVS4400 DOA? Or is there some arcane setting the quickstart guide overlooks? OR?
I'll just use the 4400n to provide DHCP to my two VLANs and then a new problem cropped up. I am unable to add a default route to the 4400n's DHCP server. It uses the 4400n's vlan IP as the default route. What I'm trying to ultimately achieve is to configure the 4400n as an access point for our "private" network on vlan1 and also "guest" access to the internet on vlan2.
I'm having problems trying to establish a IP Sec tunnel from the office to home. All of our machines are Macs so I have been using the directions described in "How to create an IP Sec tunnel for MAC Clients, A QVPN alternative" but I still can't get it to work. My setup is as follows:
The office is connected to the outside world through a MODEM (Sagemcom 2864 Connection Hub). This MODEM is also a wireless router. It's DHCP server provides addresses 192.168.2.x.The WRVS4400N's WAN port is connected to one of the LAN ports on the MODEM. It's IP address from the MODEM is 192.168.2.x. The WRVS4400N provides addresses 192.168.21.x to devices connected to it.We have a DynDNS account and are using the DDNS client on the WRVS4400N router to connect to it.At home, we have a DIR-655 router with IP Sec Passthru enabled. The router provides IP addresses 192.168.1.x for all devices connected to it. I am fairly sure there are no issues with the router setup at home since I am able to VPN into the office of my full-time job without any problems. I have tried just about everything I can think of but have not been able to get this to work. setting up the Local and Remote Group Settings on the WRVS4400N and the IP address settings in IP Securitas?
Ive setup a few WRVS4400N over the past 6 months, and have been receiving the below message from some of them every couple of hours.What does the message indicate?
I have successfully got QuickVPN working from Windows 7 64bit into my WRVS4400n. The router is sat behind another router/modem (Belkin) as the UK uses PPPoA and the WRVS4400n doesn't.So I set up DMZ and changed the DHCP to always allocate 10.x.x.2 on the Belkin which is the WAN side for the WRVS4400n as it is the only thing attached.I have now noticed, and I'm not sure whether it was the case before, that the DNS that the WRVS4400 is showing is the LAN address for the Belkin Modem/Router (10.x.x.1), not 192.x.x.1 for the WRVS4400n itself. I assumed setting the Static DNS 1 on the WRVS4400n would do it, but it didn't?When I connect into the network with QuickVPN, the computer names do not show even though I have selected the option in QuickVPN?
I have 2 WRVS4400N's available to be. One is running my network and security connected to my WAN.I want to use the other one stricly as a switch or even adding wireless repeat of my current wireless LAN.
Recently installed a WRVS4400N router on my home network. Prior to that I was using the wireless built into my FIOS router. I wanted something more secure so I went with the WRVS4400N. I turned off the FIOS wireless and am only using the cisco wireless.
Im having intermittent issues with the wireless. I have many things hooked up to my wireless including a HP printer and a Sonos system. Most of the time if I just open my ipad I cannot see anything else on my network including the printer. If I try to see the Sonos system can cannot, sometimes I can open the app on my iphone and then I can see it.
Sometimes I can see the printer and sometimes I cant. Sometimes when I do see it and then print to it, it will be gone before it even prints. I don’t seem to have any issues thru the LAN connections.
Also, ive noticed that the wifi is much slower than the old FIOS box.
FYI, when I remove the cisco and fire back up the FIOS wifi I don’t have any problems at all at any time. And its much faster.
I have tried channel 6, 11 and auto. Also turned off IPC and still no change.
I have a gateway to gateway vpn (home-office) working fine for almost an year btw 2 wrvs4400n routers, This morning, the VPN tunnel was down. I clicked "Connect" from the web based interface, but it does not reconnect.
I tried setting up a new tunnel using the VPN setup wizard, but it says it can't connect to the remote router. Which is strange, since I can ping there normally.
I'm having a heck of a time connecting the WRVS4400N VPN to another WRVS4400N VPN. both of the routers have the current firmware version V2.0.2.1: Router 1 is below, and router 2 has the matching configuration with as it should be the local group being that routers local information and the remote crew set up being router ones information. the status is up on both of the routers, but I'm unable to ping the remote gateway or any device behind it.[code]
After a few months of trouble-free ... the Cisco WRVS4400N V2 stopped working. i have tried to reset by holding the reset button for 30 seconds ... but nothing changes the red DIAG light remains on at all times
i have also tried two different versions of the Firmware Rescue Utility but all i get is "unable to scan"
This is a new device, just initially installed about a week ago. I updated to the latest firmware. We have iphones, ipads, and Samsung Galaxy smartphones all trying to connect to this WAP at this office, but cannot seem to connect. If I power cycle the WAP, we can connect for about 5 min, then it loses it and cannot connect again. I have strong signal, device says "connecting" then immediately "disconnected"... does this on loop forever.WPA/WPA2 PSK.I don't know what to do. About to go buy an Apple WAP.
My WRVS4400N is not letting my VPN client through the router. I have checked the passthrough boxes for all 3 protocols. I have port range forwarding for my VPN connections to my SBS2008 box on port 1723.
I have a Linksys E4500 as the main router and would like to use the WRVS4400N as a bridge to extend the range of my network and also attach a NAS to it. Is this possible? I've been trying different options but have been unsuccessful.
