Cisco Routers :: RV220W - Packet Loss (wired And Wireless)
Nov 8, 2011
I have a RV220W with the latest firmware (126.96.36.199) and I loose about one in every 20-40 packets.
I have tried with both wireless/wired, on different ports, laptops, and Ethernet cables.
My configuration is fairly simple:
1.) I reconfigured the default subnet
2.) I setup a WAP on the same vlan (VLAN1)
3.) I setup a WAP on Vlan2 for guests
Other than that, settings are out of box (save a hostname/etc).
just purchased it, and am thinking I'll have to phone Cisco for RMA.... There is a similar thread where people noticed this on wireless (not sure if they tried wired as I have). RV220W Packet Loss over wireless
I am having issues where different laptops are dropping packets when communicating to the WAP on the RV220W. I have placed 3 laptops directly next to the router so there is no chance for walls to interfere. From each machine 1 at a time I perform a continuous ping. Here is a quick output from one of them:

I have RV082 in many locations and it is working fine.One location I just starting to have problem with packet lose (50 to 60 %)I ping between two location which i am having problem.Gateway to Gateway shows no lose on packet (reply with 20ms avg.)but router to router will lose packet 50 to 60 %.
Recent incountered an issue with our elastix pbx and packet loss. Noticed this morning that when I turn on the firewall on our RV082, packet loss begins around the level 3 servers I see in my traceroute, and then slow spread out to all hops. When I turn the firewall back off, all hops have no packet loss or less than 1%. The weird part is, previously, I had the firewall enabled, and never had this issue.
I am connecting to a Wireless network, through a ZyXel ZyAIR G-4100v2 router. My problem is that I am experiencing very regular packet loss every minute or so. This lasts for around 5-10 seconds on average. I am running XP with the latest service pack. So far, I have checked out;Wireless Zero Config scanning of new stations (disabled that feature).Xirrus network scan (signal is fine and consistent). I am not suffering from any degredation in signal, the problem seems to be that the router is simply not allowing anything through at regular intervals.
I seem to be having packet loss with the E4200V2 which is upgraded to the latest firmware as of today, 1/18/12
The application is accessing a security DVR which uses a RTSP / RTP stream. Of course this requires certian ports to be forwarded in order for this to work. This works flawlessly with a WRT310N or a Cisco 871 Router so I know the port forwarding is correct.
With the E4200V2 it works intermittently, I can replace EV4200V2 with either the Cisco 871 or the WRT310N and there are no issues.
If I ping the AP address from a computer in the *same subnet*, I get a perfect 0% packet loss. If I ping the AP address from a computer in ANY *other subnets*, I get about 50% packet loss. If I ping anything else *other than this single AP*, to and from any other subnets, I get a perfect 0% packet loss.
Only packets orginating or sent to the AP from other subnets are getting lost.To me it looks like there is something wrong with the routing table of the AP, as if some packets were not properly returned ?
A while ago I bought a WRT320N as a trade-in offer, unfortunately I had around 20% packet loss on my connection after I set it up. If running directly through my cable modem I had no connection issues at all.I was running the whole setup cabled, and have no peripherals using the wireless connection.The router was returned to the retailer for RMA, and in the end I got the purchase credited.My setup ISP: Dansk Kabel TV (danish provider for internet, TV etc.)Modem: Netgear CVD31T DOCSIS 3.0 compliant Cablemodem (I do not have access to the modem, as it is provided by the ISP. I have now bought an E2000, and set it up in the same manner as the previous router.This has returned the same problems I had with my previous router.Updating the firmware didn't make any difference.Using Pingtest.net as my test reference I get results like this.when connected directly to the modem I get 0% packet loss, max 20ms ping and jitter is 2-3ms.Have I been so unlucky to get 2 faulty routers in a row, or could there be some problems with Linksys routers and Netgear?I have unsuccessfully tried switching cables without any change, tried moving the router "far" away from the modem, monitors etc to see if there could be any interference from the wireless.
Vista 64 Intel Pro 1000 with latest driver Here is a shot of the lagometer in COD Black Ops when all is good. I used to see this with my old WRT54GS and connected at 100Mbps Full Duplex or Half Duplex and I currently see this when connected through the E4200 at 100Mbps full or half duplex AND when connected via Gigabit via one of the 4 ports on the back of my cable modem, a Motorola SBG6580 [URL] This next screen capture is what happens when I try to connect via Gigabit thru the E4200. It either starts out like this right away or within 30 seconds to a minute this will start to occur. I believe the red spikes indicate packet loss. [URL]
I've been fighting with my E2500 since I got it back in June with lag, dropped connections, etc. It's a bit intermittent but can hang around for hours at a time when it kicks in. Restarts but the issue always comes back. Most noticeable while gaming online or on a VOIP program such as Team Speak. Generally when it happens If I'm monitoring my Team Speak connection the incoming packet loss shoots up between 20-30%, starting to drop out every other word or so. No out going packet loss. The connection drops are random between computers (I have one mac and one pc in the house) where one will be fine and the other wont, or when the whole system will stay connected and drop all transfer. In the case of this last one it's not my ISP's connection as any streaming happening between one computer and an Apple TV device will also cease. I've also swapped back to my old router (an older model linksys) and all problems have stopped. Fully rebooted and reconfigured the router about 3 or 4 times and am on the latest version of firmware (1.0.003). It was much worse on 1.0.002 but still very noticeable on 003. Also no difference with a different wireless adapter. I've tried the chat technical support but all they did was take 45 minutes to tell me how to reboot my router after telling them I already had.
Can your wireless router do a ping test to 188.8.131.52 [URL] or any other [URL] for that matter?Mine can't, either with my wireless PB G4 running OS X 10.4 or wired Dell running Windows XP. I tried it with a wrt54g v5 & wrt54g v6 both tests got a 'request timed out' with 100% packet loss. v5 had the latest firmware, v6 is still at 1.00.9
I have an E1200 and am time out and packet loss issues. The internet connection is fine for 30 seconds to five minuets and then everything times out for 15-20 seconds. Although it’s only a minor incontinence to web browsing, it makes playing games and watching videos a nightmare. “Lost connection to server error.” and the like…
I upgraded to a new router, the e1200 I am currently using, from my Tenda 10/100 N. The problems where the same that I am experience currently and the reason I bought it in the firs place.When I directly connect to the cable modem, I have no issues and everything is fine.I have run a trace route and the second hop, (the router to the modem) is the choke point.I have cloned the MAC address.I have updated the firmware and hard reset
I have throttled my MTU to automatic, 1500, and 1472. None making any difference.I have disabled NAT and all that does is kill my internet connection.I have disabled all firewalls router and windows, no change.I replaced the physical wire from the router to the modem.I have disconnected all devices except one computer, and no difference.I ran a DNS trace and I have… non routable local internet address 192.168.1.1 DNS-cac-lb-01.rr.com and DNS-cac-lb-02.rr.com.I am using windows 7 and my ISP is time Warner so-cal.
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 am implementing tcp as per rfc 793, i have one doubt, while sending first packet, if that packet lost means, tcp will wait for RTO and retransmit the first packet, and after got the ack for first packet, then only it will send second packet or without getting the ack for the first packet it will send second packet.
My workplace has a UC-540 attached to a cable modem, attached to the world wide web.
When we make VOIP outbound calls through the standard ISP, there is no auditory packet loss sympton; however, when we make calls to out sister branch through our VPN, we experience auditory packet loss symptoms.
I would think the VPN should only be affecting the encapsulation of the data. To my understanding the VPN packets and non-vpn packets all hit the router at the same time, and transport over the web in the same manner. Why would there be packet loss over only the VPN??
--Regarding QoS, if a standard layer 3 device receives a VOIP packet encapsulated in a VPN, do the QoS bits in the VOIP packet get acknowledged, or are they hidden by the VPN encapsulation?
For about the past 2 or 3 months, I have been experiencing outbound packet loss at about the same time every evening. That timeframe is about 7 PM - 10 PM. This is most noticeable on Teamspeak 3 because of the voice disruption that other users report to me.
I have recently switch internet to Time Warner. Since the day I got it, i have experienced random packet losses of 100%. I have called time warner and they are going to send a tech out. But i would like to know more about this before he comes. I have replaced the modem with a brand new one. Surfboard SB5101N from the one i was leasing from them. They both do the same thing. I have made sure all my Drivers are up to date. I have replaced the coax cable and Ethernet cable and ran my Anti Virus and Spyware program. It does it more during online game, I have reinstalled the game and was having no problems with the ATT Dsl i had before this.
I'm having an issue with packet loss during the same time every day at 12:20PM. I checked scheduled tasks, ran wireshark, made a static ARP entry, and ran ping tests. The ping tests show packet loss only when pinging 1 DB server to 1 App server. When the packet loss happens everyone on the network connected to the DB gets kicked out of the DB. They are eventually able to reconnect but its annoying that everyday at 12:20pm they get kicked out. Ping tests from the DB to the Firewall stay constant. But when I ping from the App server to the DB it loses connection at 12:20pm and when i'm remoted into the DB server i get kicked out as well. It's like at 12:20pm the DB server stops incoming connections for some reason.
When I ping my video streaming host's IP address (the IP that they gave me where I can view my IP web camera's video stream), I get anywhere from 0% to 8% packet loss at various times of the day. They're claiming that there's no problem, that this is because this is a router and it's dropping ping packets due to "ping priority giving preference to more important network traffic."
I had all kinds of packet loss and I was ofcourse suspecting my ISP. But then I tested pinging my internal interface and found that it has packet loss as well. I have about 10% packetloss to my interface with 192.168.0.254, I have the same thing from several different inside hosts. My inside rule is the implicit one, any, any. service IP.In the log I can see a teardown and build of the icmp whenever the packet loss accour.There is no packet loss pinging the outside interface from the internet.
I´m having a problem/issue with my CSM. I have a WS-X6066-SLB-APC - Version 4.2(1), installed on a 6500, and for a while now whenever I ping the VIPs (vservers) I detect some packet loss (In 10.000 ping packets, I loose around 1%), and higher response times; If I ping the reals I see no issues, only with the L3 behind the CSM.
3 days ago it worked just fine but not anymore I've run a packet loss test and the result is 100% loss. I don't know why. The internet is really slow, it is unusual. I'm using wireless network. Oh, I'm using windows XP SP3 (laptop) I am not really good at computer and I'm wondering if this problem is caused by virus, malware of something like that.
I have a Windows 7 desktop (so it's NOT wireless) that is having problems with packet loss. Now, the modem is fine, I've tested 'pingtest' on some laptops and the packet loss is very minimal. I've tried reinstalling the drivers for the LAN controller, using a different ethernet cable, using the 'winsock' reset command, and I have no luck. This does effect upload times on YouTube, to where a minute long video takes an hour.
I started using Windows 7, on two different computers. I get pretty bad lag spikes while using Skype and playing online games. They occur about once per minute and last maybe one second. There is a "Network Throttling" fix floating around the internet which I have tried, to no avail. I don't know much more about computers than a basic understanding, and am completely new to Win7.
Pinging 184.108.40.206 and had 100% packet loss; this was suggested in another thread. LAN connected at 100 Mbps BUT cannot access Internet! Windows XP HP desktop; Belkin N Router; Optimum Cablevision - Modem Scientic Atlanta "Webstar"
But I have finally diagnosed the problem. When I try to play games like Combat Arms, Arma II /OA, BF3 and run a ping test on pingtest.net my ping is steady, and my jitter is fine but the packet loss is ridiculous! I will have a packet loss of 90-100% causing the game to be unplayable. But when I run this test playing WoW I have 0% packet loss, steady ping, and good jitter. I am completely lost on what to do, other than contact my useless ISP that will not know what to do. I am really frustrated by this and am not sure what the cause of this is or what to do. I have been researching for over a week and have no where else to turn.
In my network i have Cisco nexus 4 switches those are running as redundancy and fault tolerance. I have mulitple VRF instances are running, when i tried to ping the gateway IP (hsrp Virtual IP) witch same VRF instance it is getting packet loss.
I have two routers, Cisco 3825 and 2811 connected via a p2p ethernet link. The two sides of the links have Huawei muxes with 100/ full duplex set on their interface. I am facing almost 40% packet loss but the supplier is unable to identify any issues at their end. We have tried setting different combinations of duplex and speed settings but no improvement. When set to auto/auto the interfaces are negotiating to half duplex and I am sure this is the cause of the packet loss. Also I heard of auto-negotiation on MUX ports but supplier confirmed no such settings but only 100 Full duplex. If the router iterface is negotiating to half duplex so I suppose there is some thing with the negotition problem with MUX and router port ?
On C3825 I have a Gig interface whileas C2811 has fastEthernet. I guess Gig interface should not negotiate ? Is there a way to pin point the exact fault to supplier ? Also is there work around for this?
