Cisco Routers :: RV016 Dropping Company POP3 Connections?
Oct 14, 2011
I 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 a RV016 Router with 3 internet DSL conections.
Firmware version : 3.0.0.1-tm (Jun 6 2008 20:17:06)LAN IP : 192.168.11.254 /24WAN1 IP : 192.168.1.253 /24WAN2 IP : 192.168.2.253 /24WAN3 IP : 192.168.3.253 /24MODE: Gateway.
Windows Messenger continually connects and disconnects. This behavior is permanent I only have problems with Messengers (all releases), web page access is correct. I check bandwith saturation and It's ok, I use less than 50% of each DSL. I configured the correct size of MTU for each DSL and the problem continues.Is there any way to set priority to this service? Is there any way to check if the "load balance mode" affect this kind of connections?

We have a RV016 load balancing between two broadband WAN connections. On protocols that are sensitive to a change in IP address such as ssh and https, if the client connection goes inactive for a short time (sometimes as short as 10 seconds), the RV016 often changes WAN connection as part of its "load balancing" feature. Most protocols do not even notice, but the more sensitive protocols do and often lock a session or timeout the session which is not a good thing.
We have been able to bind these sensitive protcolols to a particular WAN port but (in our minds) this is not an "ideal" situation. In fact I would consider this to be a broken "load balancing" solution and should be fixed.

I 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.

I 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.

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.

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?

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.

How does one configure the router so that Internet users can access internal company websites? The only thing that appears is the Cisco router login. Also I need to configure Terminal Services and its not on the list under Service.

A lot of the time webpages hang up and don't load.. errors out etc.. I keep unplugging the router and plugging it back in and this makes it a ton better for a little while.. however.. I can play games like BF3 on 64 man servers and not lag/spike/disconnect or anything.. I am baffled as to why I am having such issues with web browsing

I have 2 AP541N's set up using a WDS bridge, broadcasting a single SSID. I am using WPA-PSK for the bridge and WPA/ WPA2 and CCMP (AES) on the SSID. I only have around 75 (Mac, PC, iPad, iPhone and Android) devices that use wireless. Some are laptops that roam around from AP to AP, and are using LAN when they are not roaming. I have increased the roaming agressiveness on PC clients and this doesn't seem to have resolved the weak connection. At most, I have 50 clients trying to access the wireless at one time. My problem is that they keep on dropping the connections and have real problems reconnecting once it's dropped. After 4 or 5 tries, they may or not be able to reconnect.

Randomly the internet connection for either my, my son's , or my husband's pc drops. This also can happen with the X-box. The router lights indicate it is working and the rest of the connections will be fine just randomly any one of ours will fail until we reset the router. Two of the pc's are wired, one is on a plug (devlo) and the xbox is wireless. I phoned BT, our isp, who sent an engineer out. It turned out the BT rep told the engineer I had reported no dial tone on my phone line and if I had allowed them to investgate this fictitious fault it would have cost me £150 for a call out.

I've got a DIR-651 that does one of two things regularly:
1--drops all wireless connections momentarily, then re-establishes them (happens multiple times a day)
2--drops all wireless connections and has to be reset (happens every 0.5-2 days)
#1 wouldn't be a big deal, except that I keep VPN connections on two systems and have to re-establish them every time this happens. I should probably also note that this happens even on the weekends, when those two systems are not VPN'd in.
It has done this since day 1, and the firmware update did not work.

I've got a problem on 887VAMG router. It drops important connections. As customer wants to have a firewall I created ACL and ip inspect rules ,but the router drops their connections to cloud and some websites are not opening. So I removed ACL and most ip inspect rules just to test if it effects that. And left only ip inspect http urlfilter. But still they have those problems, so I'm really stuck how to configure that firewall. The below some dropping connection review:

I'm having a problem with my clients dropping the network connection constantly throughout the campus. I am using a Cisco 5508 controller and the APs are LAP1141N. At first I thought it was a roaming issue but I tested with only 1 AP and the problem persisted, I can tell you that we don't have interference problems and that our old linksys APs used to work without flaws.

We have with AP541N-E-K9 on the latest firmware.
Our AP541N-E-K9 keeps dropping all WLAN connections and will not allow us to connect via WIFI. I have to switch the unit off and on but even so sometimes it will take 10 mins for the WLAN to accept new connections. Nothing has changed on the network for months as it is a very basic scenario ie Draytek DSL Router -> Cat5e cable -> AP541N-E-K9, thats it! The AP is really only used for guest access and may have about 15 staff connected via WIFI at any one time.

After 5 years of services my DIR-655 begun acting up yesterday; first of it begun by getting REALLY slow, it could take up to 25 seconds to login into the software and up to 30+ seconds just going from one menu to another, on some instances connection (wired) to the router was lost. This morning it started dropping all connections, wired or not; first my iphone then my WDTV, after that it's been pretty much random connections. On one given moment wired works but not wireless, then wireless works but not wired and sometimes I get both but for 3 or 4 minutes.I've reset the router to factory settings, plugged/unplugged, changed cables, network adapters on desktops and the problem persists.

my configuration; ADSL2+ @ 21Mbps comes in via Telstra. Fibre optic cable trunk to main road, copper to the house, total distance 246m, hence good speeds. The phone is connected to a dual port filter with a phone and fax connected through double adapter to one port, and DSL-526B connected to other port.DSL-526B connected to DIR-655 Hardware A4, firmware 1.30. The two are set up in bridge mode, with a static IP. The DIR-655 connects to a DGS-1016D and a DGS-1008.I am running WIndows 7 ultimate x64 w/8GB ram, I5-2500K, and all MS patches.
four days ago I reinstalled my windows system. At that time, I uninstalled Tablet PC components and Windows search. I use FreeDownload Manager for my download needs, and it includes a BitTorrent client. I installed the latest version.From that point on, whenever I download any torrents the connnection to the internet resets and takes about 1 - 3 minutes to re-establish itself. I have tried going back through the several versions of the program to get back to the version I was running before I re-installed all to no avail.
I replaced the cable between wall socket and filter, replaced filter, replaced phone cable, also to no avail. I have tweaked the program settings now with only three half open connections, and I've reset the modem donezn of times. I've reset the DIR-655, and done factory resets on both and reconfigured them. Nothing has worked. I use MAC address filtering and I have ACLS which block access to various sites because of kids, and I use OpenDNS web content filtering too.

Regular email go through fine. If I send a 1mb file it seems to go through after several attempts. If I send a 5mb file it might go through anywhere between 4-15 hours. It doesn't matter where I send from. Sometimes it will say ACK or RST ACK on interface instead of RST. The ASA is running 8.3.1 code. I have tried inspect ESMTP and removed it, tried sysopt connection timewait. I am at a loss.

Trying to add inside routes on an ASA 5505 to point traffic to another gateway for other connected networks is resulting in the following error 6Sep 16200 819:13:5810601510.184.236.1265003810.170.54.1823389Deny TCP (no connection) from 10.184.236.126/50038 to 10.170.54.182/3389 flags RST on interface insideI believe the problem is due to the Asymetric tcp connection and the ASA is dropping the connection because it only see one half of the traffic.Is there a way we can stop the firewall dropping the TCP connections on the inside interface? i've tried removing the threat managment which didnt work.Annoying thing is were putting the ASA 5505's in to replace old Watchguard soho firewalls only the watchguards forwarded the traffic no problem at all.

I have a rv016 that's been in 24x7 operation since I bought it a few years back. It is out of warranty. It is connected to three cable modems on WANs 1-3. Behind it are a bunch of PCs getting IPs via DHCP. There is a gateway to gateway vpn tunnel setup on wan3 to a rv082 at another site. There is a forwarding entry for http to an internal http server. Everything else is pretty much default.
The router is primarily used to aggregate bandwidth for uploading large numbers of photos. The systems behind the router initiate the uploads and the router automatically load balances the outgoing bandwidth.
This was all working fine until just recently. The ISP is Knology who is upgrading each of the 8m/768k cable modems to 25m/5m. They are also moving from DOCSIS 1 to DOCSIS 3. They are currently in the middle of this upgrade and have upgraded the modems to DOCSIS 3 as well as the speeds to 12m/2m. The problem is that the rv016 Network Service Detection, which is set to "Default Gateway" indicates that the modems fail randomly. Usually only one will be failed, but up to two will fail the Network Service Detection simultaneously.
Knology insists that there is nothing wrong with their modems. I have removed a modem from the rv016 when Network Service Detection indicates it is in a failed state and connected it directly to a computer. It will work, but it has a different IP address and default gateway. As soon as I connect it back to the rv016, it works there too, but on the original IP address and gateway. I've only tried this test this twice so far, so it is a bit inconclusive.
Speed tests behind the rv016 are the same as directly connected to one of the cable modems. The router works normally as it has for years. Nothing else is acting funny.
So my question is, is the rv016 failing or is the ISP having problems?

Basically i got a belkin(on a tight bufdget) wireless n modem(f548633) last week. and when i first set it up it was fine except it disconnectiong everytime ia setting was changed on it and taking ages to reconnect to it.
anyway in the last 2 days its started dropping connections to anyone using the wireless. thing is it doesn't completely disconnect it just goes down to around 5kb transfer but when trying to acces the router through IP it doesn't load unless i disconnect and reconnect. i could deal with this at first as it was once every few hours but now its happening every 5 minutes. i plan on sending it back but thought i'd have one last ditch effort at working this out. my security log shows alot of ACK sends to my IP.
02/07/2011 23:26:08 sending ACK to 192.168.2.4
02/07/2011 23:26:08 sending ACK to 192.168.2.8

For a few weeks now, my router has been dropping WiFi connections, seemingly at random. When trying to watch BBC iPlayer is terrible, as it keeps dropping every 5 minutes.
Tonight my iPod Touch (iOS5) was connecting okay, while my son's iPod Touches (iOS3 and iOS4) would not. My MacBook Pro would not connect either.
The only to get things working again, is to turn the router off for a few minutes and turn it on again.
I have router wireless settings as follows:
Network Mode: mixed
Radio Band: Wide - 40MHz channel
Wide Channel: 9
Standard Channel: 7 - 2.442GHz
SSID: Disabled
Router Firmware Version:V2.00.20
My wired connection is running well:
