Cisco WAN :: Poor Performance / Packet Loss With 887VA Router On ADSL Line
Dec 6, 2012
We have a remote site connected to ADSL line with a Cisco 887VA router attached. This has been working fine for the last couple of months. However, recently, the site have started to complain of performance issues (network slow, applications disconnecting, etc)Looking on the router, we can see evidence of packet loss/timeouts from a simple ping to the internet e.g. [code]
However, we have logged the fault with our service provider and they return all line tests as clear but what is particularly strange is that they also report “and the SNR Margins are well within threshold levels (Upstream 11.5 and Downstream 15.0)” which, unless I’m misunderstanding something, seems to be completely different from what the router itself is reporting.Is there a reason why the service provider’s stats for Noise Margin would appear to be so different from what the router is reporting?

I run my virgin broadband through an old NTL modem and a Belkin router. I haveit all attached to a computer in my study along with a new 6TB Buffalo Nas drive. The computer has GIGABIT LAN. I use Belkin powerline units to relay the network around the house. In my lounge i have a blu ray player, AV amp and my sky box attached to the network via the Belkin powerline units and all run ok. This week i have added a Cambridge audio streamer but i am suffering now from a lot of dropouts and network failures escpecially when trying to stream music from my NAS. all seem to be set up correctly as per the manuals. I have spent a lot on this unit specificallly to stream my music so this is really important to get working correctly The powerline units can flash blue (fast ) or orange (slower) but i only see the orange light .My local dealer says i need to upgrade my Modem/Router and has suggested an ASUS RT-N66U which I understand is a modern 2.5/5ghz model . he says my system is overloaded
A few questions.
Is this a suitable modem for me to use on my Virgin cable broadband? (apparently there are two alternatives types of modem/router)
Is there a better alternative unit ?
Could there be another cause for my problems and if so how do i diagnose them ?

I recently purchased an EA4500. It started out working really well, but recently I noticed that my speed on my iPhone and iPad has dropped significantly. When I'm in my office where the router is set up, I'm getting around 15 to 20 mb download speed and 5+ upload speed. When I go to my living room about 40 feet away my speed drops to 1mb down and less than 1 up. I expect to see a drop in my performance the further away I get from the router, but this seems really unacceptable to me.

The wireless connection barely registers in the Speed Test within Cisco Connect - .56 download, 5.35 upload. A cable connection gives 2.4 download and 5.5 upload. The E900 is not far from the computer with no obstacles between.Is the wireless portion of the E900 set up improperly? Is there anything I can do to improve the wireless performance?

I have EA4500 acting as a router on domainless all-Windows network of two XP machines.Unfortunately, EA4500 aggressively grabs the role of the Master Browser (I am talking about Computer Browser Service) on the network (regardless in which order you power the devices up) and then doesn't serve as a working Master Browser - both Windows machines stop listing the network computers in the "Network Neighborhood" and incur massive timeouts when attempting to view the listing.A quick look with 'browstat.exe status' reveals that indeed the router has announced itself as a Master Browser device, but returns errors when you query it.Quite predictably, without the router, both machinces figure out amongst each other who will be the Master Browser and everything works fine. The problems begin only when you add the router to the network.
1) Is there any way to make EA4500 work like a full-blown Master Browser (the one that not only announces itself, but also serves as such)? having a Master Browser integrated in "always-on" router would really improve the predictability of the network.
2) If not, is there any way to disable the Master Browser on EA4500? For now I managed to achieve that by assigning the router to different workgroup name, but this is lame, as I now can't connect a disk storage to the router and use it within the same workgroup.

Im getting really poor performance on my 1841, my intial thoughts was a duplex mismatch however although im getting a few CRC errors (root cause unknown at this point) not enough to suggest that the this is the issue.
Heres the config:

I am backing up massive amounts of data to the cloud. Everytime I do this, the wireless performance on my EA4500 seems to degrade to half its throughput. I am using the 2.4 GHz band.

I have been trying to connect a new Cisco 887VA Router to the Internet using ADSL via PPPoE and have been unsuccessful. The DSL line is active and functioning correctly since the current "old" router is connected and working without any problems (the "old" DLink router is connected to an Alcatel DSL Modem). AT&T provides the ADSL service to the office. When the Cisco Router is connected it tries to negotiate a connection via PPPoE on the WAN interface but utlimately fails. The IP for the WAN interface is dynamic.
Below is the current configuration of the router.

having a very strange problem with a Cisco 1861 running - Cisco IOS Software, C1861 Software (C1861-ADVENTERPRISEK9-M), Version 12.4(24)T5
The issue -I have suddenly started to get performance issues with downloads and access through the ZBF. Without the firewall enabled and just having NAT enabled and routing , downloads perform as expected - ( have been using Itunes download as test file ) - with the ZBF enabled , and the necessary rules installed to inspect & allow traffic - downloads stall - and the only way to get the downlaod to start again is to pause , then resume. The stalls are anything between the first 25 - 120 secs.
I have debugged and performed packet traces - but cant see anything untoward. I have also placed another router ( just a cheap Belkin ) on the ADSL service and again , the downloads work as expected.
one further thing to add is that when im tunneling through the firewall ( VPN ) , then downloads do work as expected - suggesting that the issue is with native HTTP(s) traffic.
I have upgraded from T4 to T5 - and the symptons still remain - I am thinking that these may have been introduced when i upgraded to T4 a few monthes ago.

My problem is that i have a packet loss of like 2% to 6%, which is a lot considering that i play a lot of Online games, causing lag spikes and net frozes.I will say all the information i can about my pc.My PC hardware hasn't been modified, so the manufactor page ( ) tells what is installed in my pc.About software, i need to find if this problem is software-based, my AV is Microsoft Security Essentials and i use MalwareBytes too.About how im connected, im connected via Wireless to a router. (dunno model, i just know its a encore router)

I get 10Mbps download, and 1Mbps upload. I play on wire, not wireless!I have a WRT54G2 router, and I've had it working for around 2 years now. I've been gaming(Unreal Tournament 2004) with it and now-a-days I've been getting packet loss and it is super annoying. I keep getting owned during game play because I skip here and there and it lags sometimes. Also, the laptop upstairs that the family uses sometimes can't connect to the router, so I have to unplug then replug the router for the laptop to connect to the router. Is my router giving up? Its a G router, should I shift over to N anyways?

I replaced a Dir-655 at a coffee shop, with a new dir-655 a few weeks ago. They keep calling and saying that Windows clients are not working and that Mac clients do.My first thought is that they are overloading the router but I would think that all computers would have problems not just the Windows computers. could the router be so bogged down that it takes to long for DHCP request for windows computers assigning the IP twice?

We use MS RRAS services behind a Cisco ASA 5520. In testing the performance I have found that we can only get a little over 2MB of througput when connected to the VPN server over a broadband connection. I have verified that the issue is not the RRAS server itself as I can connect to VPN from the LAN and the througput tests at 300-400MB. I also connected to the LAN directly on the outside of the firewall and only get 4 or 5 MB from there which does not seem right. None of the switches are showing any errors. I believe that I have the passthrough stuff setup as I should. I even went through these steps as recommended by Cisco.
hostname(config)# class-map pptp-port
hostname(config-cmap)# match port tcp eq 1723
hostname(config-cmap)# exit

hostname(config-pmap)# class pptp-port

I have a Catalyst 4006 with Supervisor II engine. I have 48 port 10/100/1000 blades installed in it for connection to my servers. I am having a lot of problems with performance when connecting servers that are using 100 MB NICs. The speed of the connection is really bad. I have attempted setting the ports and NICs to 100MB Full duplex instead of auto-detect, but still get the same results.
I also have a 10/100 quad-port card installed in a NetApp filer. All four ports are trunked together and connect to 4 ports in the Catalyst. The ports in the Catalyst are trunked using the Port Channel feature of the CatOS. When I look at the port statistics on 3 of the 4 ports from the quad-card, there are a ton of runts and errors (both transmit and receive). The 4th port is fine, no errors.

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.

I have 2 RV042 routers with identical firmware (1.3.13.02-tm) and settings. One router is a backup that sits in a box, but both experience this problem. The WAN port gives very poor performance most of the time. Download speeds range from normal, 25mb, to less than .5mb. Pings from my command prompt or the routers "Diagnostic" page, even to the cable modem, are almost always above 500ms. However, pings to internal resources are fast, usually under 5ms. If I connect my laptop directly to the cable modem I have no speed issues. The problem occurs whether I use WAN1 or WAN2.
If I restart the router, speeds are fine for a few seconds and then it begins to slow down like someone is turning down a dial. We also regularly experience a complete internet disconnect quite often, and when it happens, the ping results are the same when it comes back up, almost like the router is restarting itself. [code]

We have two Cisco AP541N running our wireless network in the office. They're configured with the same SSID, so that people are automatically switched between the two access points depending on their location in the office.
Frequently we are experiencing very poor performance of our wireless connections and it seems to be related to when 4-5 clients are connected to one access point. After restarting it (which also moves the 5 clients to the other access point), the performance problem goes away for a while.
I've upgraded one to firmware version AP541N-K9-2.0(1) (the other is running AP541N-K9-1.8(0)), but it doesn't seem to work.

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.

I'm facing an issue since 2 month now , no one is able to tell me what's going on. The line goes down suddently for 2 or 3 minutes and this happens everyday at the same range (~2 or 3 hours) of time . I don't have any scheduled task to cause this. ISP in his side has also made some tshoot but found nothing and is convinced that the problem is coming from our side :
Here is some log :

A few days ago I received my DIR-655 I ordered off Amazon and hooked it up. There were no problems the first day after initial setup. The next day I noticed that I was losing internet connection even though the wifi indicator on my laptop said otherwise. This happens for about 5 minutes at a time and on other devices such as my desktop and my iPad. And I hopped on Call of Duty last night and played a competition with some friends and gave everyone 4bar connection. Later that night, I was playing some more and people that connected to me received 1bar connection and I got that in return on their connection. I feel that the router isn't working with my devices right?

We have recently purchased some Cisco 3750x switches and we are getting complaints from users that the performance is poor when both the PC's NIC and switch port are fixed at 100/Full?
There are no errors or collisions on the switch interfaces so there is no obvious problem on the switch. The PC's are standard DELL Optiplex 755/760's
or gx 520's.
Any performance issues when configuring the switchport to 100/FULL?

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 66.161.11.90 [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

Im new to Cisco equipment and weve just upgraded to a all singing 8000 series (887VA) to be precise.
i'm having difficultys in setting the router to connect to our BT ADSL2 business broadband, we have a static IP but on normal cheaper routers you just input a Chap username and password. and the router sorts the rest.
i've followed the tech support from cisco website inputted the configure commands to create the ATM0 and a Dialer0 but still having no joy.when you log into the gui it only shows you a enable PPPoE tick box. no signs of PPPoA?
