I have a small business network including 2 QNAP 219 NAS servers. Several times we have noticed, the connection to the servers are lost. We have tried to restart the servers without luck. But when we restart the router, all problems are gone and we can reconnect.
View 2 RepliesI cannot seem to see my server behind a cisco router. I have a feeling it is because our network phone system may be robbing the IP address?We have two fixed IP addresses.The first one, is assigned to the router.We have two swtiches set up behind router and all the other network stuff interanally wrks great.We also have full internet access. When I type the IP in on the web, it accesses the talkswitch phone system.I have set the internal IP to the server as fixed.I have port 21 open for FTP.When I run a test, the internet sees port 21 open. However, I cannot seem to cal lup the server over the internet. Could the talkswitch system somehow be interfereing with the logon?What would the proper syntax be to access the server?

In my QNAP I can scan for upnp routers to set the forwarding port automaticly.
But it keeps telling my, it can't find an upnp router on my network. My E1000 was found without any problem!
If I open the port manually for example FTP 21. I cannot get acces from the internet, it keeps telling me its closed.
I forwarded it to the right ip. an clicked to apply. The website from QNAP says the E4200 is certified for upnp
So tho sum up: I cannot acces my NAS from the internet.
My setup:
Modem/router (ZIGGO) --- Linksys E4200 ---- QNAP 412 turbo
Linksys E4200 firmware 10.04
Right now on my internet, we have U-Verse, so one router is the AT&T U-Verse one which is downstairs and I also have another router upstairs which is a Netgear oneThe problem is, the U-Verse always stays up, but on the Netgear router, it will sometimes randomly drop signal and the signal is no where to be found on devices with WiFi. I'd have to disconnect and reconnect the router for it to be seen again.They are both on the same internet network U-verse, I just have 2 routers because the devices I keep upstairs I connect to the upstairs router.
View 1 Replies View RelatedI just recieved a new RV180 yesterday and it will not connect to my switch. Router was updated to the newest firmware, reset to factory settings. I did change the ip and ip range. Router works fine with one computer attached direct. As soon as I connect my sf300-24P to it, the WAN and LAN lights all light up and then go out. Only the WAN will light back up. I have no connectivity to the router. I plug the laptop to the router directly and no LAN lights come on and can not see the router with arp -a.
View 6 Replies View RelatedI have my RVS-4000 configured using static IP addresses in the LAN configuration. The users use DHCP to get their addresses (for the most part, a couple may have static IPs set on the computer). I have the maximum number of DHCP users set to 1 to restrict the ability of people to log in to the system. That one address is locked down.
The internal address of the router is set to 182.168.2.1. It doesn't conflict with anything on my network. I have 35 static IPs. About half of them are uing IP Based ACL to limit their access time but that doesn't seem to bear any relationship to what drops off.
Almost daily one or more of the users will lose their IP address and a hard reset of the router is required. The user this happens to seems random and it may be more than one but seldom all of them. The network includes Windows7 (Home & Pro), a FreeNAS, Macs (Leopard and Snow Leopard), iPad, iPods, an iPhone and an AirPort Extreme used as a WAP (DHCP is disabled). The AirPort is plugged directly into the router and has a staic ip on the RVS-4000 but is set to DHCP. It seems to be the most common problem child.
Model: WAP4410N-A V02
Firmware version: 2.0.3.3
Deployed 3 of these as WAPs. No repeaters. They are spaced at least 50 feet apart over three offices, each in a server or switch room.
Across multiple laptops, and multiple WAPS, the wireless will function fine for a while with good bandwidth..then the connection will simply drop. By simply resetting the connection on the laptop or turning the wireless off then on, the connection typically returns, at least for a period of time before it drops again.
I’ve tried these configured as three separate SSIDs on identical channels, as well as one SSID for all three with different channels (preferred for a seamless wireless), and the behavior does not change either way.Based on some other threads, I tried forcing the LAN port speed to 100 mbps, but the problem persists.
It appears we might have an issue with our RV082 (v4.2.1.02) dropping packets during the teardown of many TCP conversations. I have attached two packet captures of what I believe is the same conversation. One is from outside the router (Wireshark using an Ethernet Tap) and the other is from the client inside the router (SLES11SP2 running TCPDump). These are both very small captures 9 packets and 18 packets and I'm hoping it will identify the problem.
It appears that the RV082 is prematurely closing the natted port used to communicate with the host outside the network. The host sends a FIN, ACK packet, to which the client responds with an ACK, However, when the client then sends his FIN,ACK sequence, it never makes it outside the router. The client sends a total of 9 FIN,ACKs trying to contact the outside server, but none of those appear to make it through the router.
Is the router slamming the door prematurely? (I've been fighting with this problem for 3 weeks now!)

I did install server system with mscs and Domain controller and Active directory.I want to connect this dc/ac server from other places such as korea / and japan.
I have a public IP But our country ISP Don't open 135/445 port for security. So I can't connect DC/AC server from other places.At this time i did read many article and find good way to handle it. Is it possible for other servers to connect DC/AC server by using the RV082 VPN service.
Some day, then my internet jut died. then I got the router restarted(unplugged the electricity and plugged it back in) and it worked for like a day and then it died again. I restarted the router again Internet worked and then some hours later it died again.This problem only happens to me and not anyone else in the house.I'm connected from my pc with and ethernet cable to a switch/HUB where it's then connected to the router.
View 8 Replies View RelatedI 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?
View 10 Replies View RelatedI 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.
I have a cisco RV180 hooked up to a cisco cable modem and Cox service.
The basic symptoms of the problem are that every 10 minutes or so external connections will hang. This lasts maybe 20-60 seconds. If you're loading a website when this happens, various parts of it won't load and firefox will sit and spin indefinitely (it seems) until you manually stop the loading and click the reload button.
When this is happening I can still connect to the routers webserver and dashboard that auto-refreshes every 10 seconds. It seems perfectly fine. My initial theory was that something was broken on the Cox end of things, but after swapping out the RV180 with an old on-q router we had laying around, we haven't seen the problems.
Some other differences I've noticed between the on-q and the rv180:
* with the rv180 traceroute to external hosts shows a big delay (500-600ms) at the hop right after the router. With the on-q, it's 12ms.
* when I ping the ip of that hop with the large delay, with the on-q I get no responses. With the rv180 I would get these strange host redirect messages that make it look like that ip is redirecting to itself. There would be 1 or 2 of those redirect responses, followed by 3 or 4 errors, and every packet would be listed as an error in the ping summary.
We installed one of these devices as our gateway a couple of weeks ago, flashed the firmware to 1.2.4(003) and it worked perfectly until this morning where it keeps resetting the ADSL every minute and losing the web interface to the unit.
The log endlessly reports this:

I have following issue with RV220W - the router seems to be dropping parts of traffic coming through it. The unit is brand new, the firewall is turned off, there are about 20 computers and 15 VOIP phones connected to it via Zyxel GS1910-48; all IPs are set to static DHCP records, in the last 3 hours the router rebooted about 3 times, then I turned on the log in. The router is producing insane number of warnings, as you may see from the log attached. I found this thread [URL] but no answer regarding this issue.

A couple of days ago, after a suggestion in a old forum post (rv180 dropping connections every 10 minutes or so) I tried increasing the various session timeouts. This didn't seem to affect anything for the first day, but last night the router started becoming unresponsive (not responding to pings, but maybe continuing to route established connections.) After a couple minutes the router would be pingable again, and as soon as i could I reverted the changes I made to the session timeouts. That didn't seem to fix the problem. Logs showed many many warnings saying "nf_conntrack table full, dropping packet."
Then as soon as I got on the phone with small business support the problem seemed to correct itself. The only thing we changed was decreasing the MTU to 1472. It is strange that the MTU would make a difference all of the sudden, isn't it?
Recently I have switched from DSL to Comcast Cable. In the PPoE settings you can disable DNS from ISP. However, now since I have to use DHCP I cannot disable the DNS from ISP.If I change the DNS on the LAN or change the DNS in my adapter properties (in local machine) this makes my Brother printer loose connectivity.How can I get the openDNS servers on the WAN side of the RV220?I do not have a static ip address from Comcast either....

View 2 Replies View RelatedI am getting crazy with our Cisco Linksys RV016. It handles 3 simultaneous connections to the internet using 3 ISP. All our company goes to the internet using this cisco linksys RV016, our corporate switches are connected as clients to the router. Sometime ago, this router started to drop POP3 connections to our network, when this problems is present, all users get Receiving' reported error (0x80042108) in Outlook 2007-2010. Currently i have setup POP3 service to use the First ISP connection, but when this problem is present, the only way to eventually resolve it is to switch the link POP3 Service from the First to the Third ISP, sometimes it works immediately, sometimes don't. We are using this router since 2007 but this problems started to arise from this month.
Our switch is the latest firmware available is Cisco website, this is the Firmware Version: 3.0.2.01-tm.
I have recently installed four Cisco RV042 v3 VPN routers for a customer of ours to replace existing Nortel Contivity 1010 devices which were providing VPN tunnels from the customer's 3 branches to their headoffice. The original Nortel devices were working perfectly but the customer wanted some firewall rule changes and the Nortels were proving to be somewhat inflexible and incomprehensible in their configuration hence why they were replaced.
When installing the Cisco routers I configured the VPN settings to match the Nortel device settings so that I could swap out a branch at a time without taking the whole setup down for a day.The customer has a Unix based dumb-terminal application running on a server at headoffice that they access from their branches using terminal emulators on Windows PCs and thin client hardware devices that support vt100 terminal emulation.
Prior to installing the Cisco RV042's everything was working fine. Now they are using the RV042's they keep getting the sessions from their branches dropped. Both PC users and thin client users are losing sessions and it happens with active and idle sessions. I have checked the logs on the routers when users are disconnected and there is nothing logged at that time (other than my login)... I had thought maybe it was to do with tunnel renegotioations so I have set to phase 1 / phase 2 SA timeouts to 86400 & 28800 seconds respectively but this has had no effect. I had also seen somebody advised disabling 'SPI' in the firewall... I have tried this and it makes no difference.
We have a newly-purchased RVS4000 v2 with firmware v2.0.2.7. Its intended role is as a gateway between our local network of wired workstations and a Cisco 2800 series Integrated Services Router, which is at the receiving end of our T1 line. It is configured with static IPs on both the LAN and the WAN side. It does NOT serve DHCP for the LAN. Ever since I installed it, I have had repeated complaints from users of Vista and Win7 workstations that they lose internet connectivity about every 20 - 30 minutes or so. The only solution is to unplug the workstation's CAT5 cable, count to 30, and plug it back in. Then everything's hunky dory for another 20 - 30 minutes. Meanwhile, all our Windows XP and Linux workstations enjoy uninterrupted internet access. The router/gateway we replaced (a DLink DIR-130) never had this problem.

Problem: Internet 'lags out' every 10-15 minutes for approximately 3-10 seconds. It only does this when I'm connected through the router and never when I'm plugged directly into the modem. It happens most commonly when my brother and I are both online at the same time. It's rare when we only one of us is online.

For the past few months my internet connection will randomly drop for about 5-10 seconds when someone else connects to the network. I am using a wired Ethernet connection and as said when someone connects either via WiFi or also through a wired connection, the internet for me will drop as soon as the device is connected, and then randomly every 20 minutes or so thereafter. I should also mention that rarely the connection will just drop for again, 5-10 seconds even when nobody else is connected.I tried my computer at someone else's house using their router and it worked fine, no disconnects at all.
View 1 Replies View RelatedI have two wifi routers which I have connected together with an ethernet cable to extend coverage across my house. The ethernet cable is connected to a LAN port on the first router and the internet port of the second router. This works fine and creates a second network that I can connect to the net on. The problem iseemingly randomly, about every 15 minutes, the second router will lose internet connection. My laptops and phone still stay connected to it, but windows lists it as having no internet connection. If I then wait a couple of minutes and reconnect, internet will be working again.
