Cisco WAN :: 1941 - Speed Slow After Connecting To Router
Apr 6, 2013
In my company bought 20 mbps lease line(ISP Line).I connect directly with my laptop and after checking it show 20 mpbs speed.If i connect cisco 1941 router and configure PAT and Its working fine but I check with speed I connect directly to another interface on my router to laptop at that it show only 8 mpbs speed.I am check with ISP person but they told its not an issue in ISP because we connect directly it show perfectly 20 mbps speed but connecting with your router at that time it show 8 mbps speed,so problem with your router configuration.

Recently my desktop has experienced very slow download speeds (~0.11 Mbps), however the upload speed appears to be in line (~2.0Mbps). These numbers are taken from Comcast's speed test (my ISP). It is obviously a problem with my PC because everything else on the network (PS3, Laptop) have great signals with no problems. I just recently reverted the Desktop back to its factory state, and everything was working fine for a couple of months. The desktop in question uses Vista 32-bit and the Belkin Basic USB Wireless Adapter.

I live in the tampa bay area, I have bright house (BHN) as my service provider, which provides a Road Runner Lightning (40/5) package. I previously used BHN's top tier (20/2) back in July (and prior) with no problems.
After converting to Lightning in August of this year (2010). Of course, BHN (and every other provider) wants to force a modem/router down your throat, so I had them bridge it (in short, turn it into a dummy modem with no routing). I had an SMC branded modem gateway at the time. I work from home 2 days a week (so I can spend more time with my kids during morning, lunch, right after work) and this requires me to use QoS to ensure my VOIP work calls don't get dropped, if the family is watching youtube videos or watching netflex.
My network was as follows SMC Modem >WAN IP>>WAN Port>>D-link DIR-655>>Switch Ports>PC1, PC2, PC3
Everything seemed fine (from a usability stand point) till about 2 weeks ago when my upload speed seemed to grind to halt. Normally I was able to upload about 200-300K per second, and I noticed this dropped to about 45K per second during a drop box upload. First thing I did was power cycle both my modem and router (in the proper/usual order). After they both come up, I start using speed test to find out what my upload speeds were. I was getting about 39Mbps down, but only .56Mbps up still. I factory reset my router.... test, similar speeds. Power cycle all computers (just in case), and then modem/router. Tested, similar speeds. Updated the firmware to the latest. Same issue
Called BHN customer service, they factor reset it, but it wasn't in bridge mode. If I by passed the 655, in factory mode (non bridge mode) upload speeds returned to better than expected states. If I bridged the cable modem, upload speeds seemed to crash.
Had BHN replace the modem, seemed fixed for a day, then issue came back. Had them come back out and replace it again, this time with a Motorolla Surfboard modem... same issue. Fine during factory reset, however after they bridge the modem, upload speeds were fine. Told BHN I would take it from there.. Connected up the DIR-655, and upload speeds crashed again. (.6Mbps). Called D-Link Support, and the Chinese English speaking rep seemed to not be listening to me and tried to have me adjust my MTU as well as Wireless settings. Long story short... the rep was a level 0 id10t and I hope D-link will consider hiring better employees/contractors. So I was all about to give up and replace it with a DD-WRT capable router (which it takes me a lot to want to swap hardware), when I discovered the wan shaping was on. Which I thought to myself... nah... QoS has never messed up before... why would it be the cause. Turned off wan shapping... and voila. Issue seemed to be insta-resolved.
Unsatisfied with that... I decided to dig a lil deeper. I turned on Wan shaping again, but decided to set the settings manually instead of auto detect.
Here are the settings I used... (Advanced Tab>QoS)
Enable Traffic Shaping - Checked
Automatic Uplink Speed - Unchecked
Manual Uplink Speed - 5000
Connection Type: Cable or Other Broadand Network
Enable QoS Engine - Checked Automatic Classification - unchecked (this checked seemed to affect my upload speed by about 5-10% during testing) Dynamic Fragmentation - unchecked (this checked seemed to be the worse enemy for upload speed)
While I know I'm not any network guru (still have to use a subnet calculator for subnetting), I think I did a pretty good job drilling down the issue (once I got passed my service provider replacing modems).
Anyways, I've had overall good luck with D-Link products, even have a 5 port 10/100 switch (all metal) from 1998 that works great. Hopefully, D-Link will just either put more documentation on the web, or hire better employees.

I have a Cisco 1941 which has several Cisco VPN clients connecting to it which all works fine. The details of the LAN and VPN clients are as below:
Cisco 1941 LAN : 172.16.1.0 255.255.255.0
VPN Clients : 192.168.5.0 255.255.255.0
As mentioned this works fine but I'm about to setup a point to point VPN with from the above Cisco to another site which isn't controlled by myself and the remote side of this point to point VPN will only allow connections from the "172.16.1.0" subnet to communicate with it.
The issue I have is that the Cisco VPN clients also need to communicate with the remote side of this point to point VPN but they are obviously coming from the "192.168.5.0" subnet. Is this possible and where to start with this that would be fantastic.

i have a laptop that i connect through our wireless router with, and for the past couple months my download speed have been terrible. my browsing speed is just as fast as it always was when i am connected to our router, just incredibly slow if i try to download or stream something.however, my downstairs neighbor also has a wireless router set up that i can access which gives me incredible download speeds but my cant even browse the internet because i the browser connection times out.i have tried plugging directly into my router to on the thought that perhaps the 2 routers' wireless was somehow interfering with each other, but my download speeds are still *** even then.

I've recently bought a 3G, 32MBit/sec (DC-HSPA+) connection with a ZTE MF680 Modem and a Dovado 3GN router. When I connect the modem directly to the computer I get around 20-25MBit/s which is great and acceptable. Problem is when I connect through the router I get max 3Mbit/sec.Connected via ethernet cable or Wireless (n/b+g+n) gives the same low speed results I have used the same APN (bredband.tre.se) in my router as is on the modem I have upgraded to the latest firmwares on the Router (latest firmware 5.0.5-3)I have swaped my modem to another one, to the Huawei E372 (latest firmware 11.203.05.00.00).
I have swaped my Router to another Dovado 3GN and updated to the latest firmware The modem is placed 2meters away from the router to reduce interference I have removed all my anti-virus and firewalls and I believe the router has no firewall and prior to that did a virus check, also with spyware doctor. I changed the SIM card, and got another from the ISP, no luck. The router's support says they recieve full speed (like 20Mbit) with the same hardware and firmware combination The 3G modem is exactly in the same place where I do the speed tests Speedtests done with [URL] and [URL] Pings are quite high in both cases when doing tracerts but while doing the speedtests they are between 45ms and 75ms?I have moved the config to another room, same results I have tried using no security on Wifi and also disabling WiFi. I have tested with 4 differnet computers with totally diffferent configs

I have brand new Cisco E4200 and WD Passport 500Gb.When it connected to router wireless (802.11n 300Mbit/sec) file transfer speed is around terrible 3 MB/sec. Same hard drive directly connected to my Mac Book Pro Unibody produce 30MB/sec. However my internet connection thru the router fairly shows 12MB/sec.It sounds funny, but for me is 4 times faster to download file from the Web rather the from hard dive that I'm holding in my hand.

We have a 861 router for our small office with 15 people. We have been experienced download problems for several months, but we have suspected the internet supplier to be the bottleneck as we have a new 861 router with the default configuration from the "Cisco Configuration Professional Express".
The sympton is that the download speed over http starts fast, but drops after a few seconds from 10MB/s to 3KB/s and stays there. The internet supplier came here today and made some tests. So we downloaded some huge files over the direct cable, and it was staying at constant 10MB/s. When we connected over the router it started at 10MB/s and dropped down to 3KB/s.
Is there something that has been forgotten in the "Cisco Configuration Professional Express"?

I have FiOS and their supplied wireless router Actiontec #MI424WR. I have home theater equipment that uses the newer N signal so I purchased a Linksys E3000 Wireless-N Router. I have one of the LAN outputs on the Actiontec feeding the Linksys input and Wi-Fi turned off on the Actiontec. This is working good for my wireless home theater equipment but I am having problems with my wired speed. It has gone from averaging anywhere from 20 to 30 mbps on numerous test sites when plugged into the Actiontec to averaging around 10 mbps when plugged into the Linksys.
1) Is my wireless N speed going to top out at 10mbps or less since that is all the router is showing on wired? Shouldn�t N be broadcasting a faster speed if given the ability?
2) I have my computer currently plugged directly into the Linksys verses the Actiontec. This makes it easier to program the Linksys router. Since I am no longer using the wireless part of the Actiontec there really is no need to be plugged into it. Is there anything I can do get the speed higher on the Linksys, a setting I can change? Will I have to plug the computer back into the Actiontec to get the higher speed and then move it every time I may need to make a change to the Linksys?

I recently switched from Linksys WRT54G router to MediaLink router. My wired connection speed stayed the same but my wireless speed degraded significantly - roughly from 5-8mbps to 200-300kbps.I measured my wireless speed both on win7 laptop and iPad. My Roku box is also struggling. All devices were in the proximity of the router.I tried changing encryption (WEP/WPA2/no encryption), mode (from b/g/n to b/g to just g), and different channels. Nothing worked, the speed is still very slow.

I have two routers set up. It goes from the modem through a WRT54G2 to a WNR2000. I have one pc connected to the WRT54G2 that gets 20Mbps and another connected to the WNR2000 thats only getting 5Mbps. I realized recently I have them connected to each other wrong. Or so I assume. I have the fourth port on the WRT54G2 connected to the internet port on the WNR2000 and it's set to "Automatic Configuration - DHCP" and "DHCP Server" is enabled. From what I read one or both of those is supposed to be set to manual.

I am getting very slow download speeds on my wireless router (Linksys model#WRT160N). I measured it on speedtest.net. with my ASUS laptop, ASUS Transformer Prime tablet, and 2 Ipod touches. All similar speeds.
-Download avg: 1.30 Mbps
-upload avg: 6.20 Mbps
I measured my desktop speed that is hardwired through the router to the modem.
-Download avg: 30.00 Mbps
-upload ave: 6.20 Mbps
I have scanned all the wireless connection in my area and found them to occupy channels 1, 6, 11. I tried changing my channels one at a time for all 11 channels. Some did a little better than others but not a lot. Also, if I buy a dual channel router, can all wireless devices pick up on the 5GHz spectrim and if so, could this alleviate some interference? Is it possible that my router is going bad and a new single channel 2.4 GHz router will be fine? jasonmac73 has chosen the best answer to his/her question.Click here to view the answer that was selected.

I bought the new E2500 Router about 5 months ago and it was great until one day the wilreless part would not give me any speed at all. I ran a wired test of the router and I would get full 30Mbps speed that I'm supposed to get. So after firmware updates and everything else I took it back and got another one.It has worked great for a month and today it's now doing the same wilress slow down issue. I can run a lan connected test and get full speed. But wireless is bouncing around at 5Mbps~13Mbps. No where near the 30Mbps I'm supposed to be getting. What is causing the wireless to bomb like this?

I have a problem with new E4200 WAN speed. I have 1Gb connection from my ISP, and my old Netgear router gives me about 350 Mbps WAN speed, but with new E4200 I only got 110 Mbps max download speed.Cisco live support tried suggested to change MTU from Auto to 1400 (and try different wlan channels, even that I don't use wlan). This MTU size change makes no difference with WAN speed. I have latest firmaware installed, router reseted several times, tried different cables etc. Also with same cable sets my old Netgear still gives about 3 times better WAN speed.WAN port (and all LAN ports) seems to negotiated at 1000 Mbps at both ONT (optical network terminal) and Linksys settings page, but unfortanately there is no way to change the setting from auto to manual at E4200 settings (and it is not possible to change any settings of ONT by user). I was thinking that if somehow it won't auto negotiate properly (even if the setting page says its ok) but maybe it actually negotiated 100 Mbps port to WAN.

I just purchased an e1200 wireless router. Wireless speeds seem to be very slow. I'm trying to transfer 1 file to my media server, and am only getting 221kb/s. Also, internet connection seems to be slow as well (though if I plug directly into the router or the modem, I get speeds of 25Mbps, however when connecting wirelessly via the router I get speeds closer to 2Mbps (according to speedtest.com).I've played around with the settings as per other posts, and seemed to get the best speeds with the following config (however it is still very poor):
- security mode: WPA2 Personal
- network mode: B/G (have also tried N, which gave worse speeds)
- channels 1,3,6,9, and 11

I bought a EA 3500 router and my speed is going only half the speed it was without the router.I have charter 100 meg internet, and a alienware Pc with a gigabit card.I wa going 100 megs and now I am at 38-50.I have tried hard reset with the bottom button, I have turned off all firewalls, I have changed my MTU to 1400 and 1500, I have went to speedguide.net and ran a optimizer., I have tried just about everything I can think of. firmware is up to date.
Is there anything I am missing, or am I not going to get these speeds with this router, I was told when I bought it, it was what I needed, Was I duped?, or is there just some setting i need to fix i am not aware of?

The smile was big when I bought my new Linksys E2000 Wireless Router.
Unfortunately the smiled stiffened when I realised that the network speed did not meet the expected up to 300 Mbps for Wireless and x10 for a Giganet connection. What to do to improve the LAN speed to an acceptable level ?
Network:
* Linksys E2000 ; WPA2 (Personal)
* x2 Windows7 Laptop ; x1 Linux Laptop ; x1 Qnap TS-409 Pro
* Download speed WiFi (between laptops as well as from NAS) <2MB/Sec
* Download Speed Cable (between laptops as well as from NAS) <8MB/Sec
* Download speed with direct connection to NAS (without switch) ~13 MB/sec

I just setup an EA4500 last night and found the downlaod speed became 1/10 of my previous E3200 before. I tried to use different channels & 20MHz only for wireless connection but no success. The wired connection through Ethernet port was in the same low speed. What else should I try?

I have this WRT54G wireless router and I just updated the firmware and everything. But I ran a speed test and the wireless speed is less than half the speed when I connect my pc to the router with a cable. i.e. I have a 32 Mb connection and with cable I get +31 Mb, but with wireless I barely get 13 Mb.

I've recently purchased a WRT160N router, and I'm using it in conjunction with a WMP54G wireless PCI card. I've set the router up to my requirements, and can get a stable wireless connection.. but internet speed seems excessively slow. While I'm able to get up to around 4MB/s transferring files over the network, running speed tests, it consecutively shows my download speed to sit around 400KB/s, whereas I'm able to get a steady 1.1MB/s on another desktop that is wired. Disabling the LAN adapter on that computer, and connecting via wireless, brings down the speed that that computer is able to get to around 400KB/s as well. Hence, I don't think it's my wireless cards, but something to do with the router itself.I'm also experiencing lag spike issues in online games, which I can only attribute to the current wireless setup, because I've previously had no issues with it. All relevant ports are forwarded, so that is not an issue.After doing some Googling on the subject, someone had suggested running SpeedGuide's TCP Optimizer, and changing the RWIN - I ran it, and set it to the 'optimal' settings, and after a reboot the wireless seemed fine - I was getting just a tad under what I should (about 950KB/s).. but after a short while, it just went back to 400KB/s. After further investigation, it seems that Vista automatically changes that RWIN value to optimize network traffic.. but I never had this issue with my old wireless gear, so I can only assume that the way Vista is reacting is based on the way the router is interacting with it.

I have had a EA3500 router in front of a 3Mb ADSL connection for about 6 months. This delivered essentially the same WAN performance as the WRT54G (v5) I replaced with it. Either router would get 2.4-2.8Mbps through a variety of speed test sites, inlcuding the CCC builtin speed test.I upgraded to a 10Mbps cable internet connection today, but the EA3500 won't deliver any more speed than with the old ADSL connection. The reason I am blaming the EA3500 is that if I plug my computer directly into the cable modem, I get a solid 9.9Mbps down/0.99Mbps up, which is exactly how my line is provisioned. With the router in place and active, I get the same slow WAN connection, 2.8-2.9MBps, whether using a PC connected with GigE, a PC connected via Wireless-N, or with an iPhone. This all implicates the EA3500's WAN connection.
Is there anything that can be done do let the EA3500 work properly? I upgraded my firmware today in hopes that that would change something. But, I get the same speed with the latest firmware (1.1.39.145204) as I did with the previous version. Speed across my wired LAN is excellent; I can sustain 70MB/sec from my PC to my NAS. It's only the WAN connection that is performing poorly.I can downgrade to the non-CCC firmware if that would make a difference; would it?

I came home yesterday and my Internet was really slow. I later found out that it was due to my Linksys E3000 because if I bypass my E3000 and go directly to my cable modem, it work just fine.I tried reconfigure, update firmware, factory reset and none of these has worked.

So I went out and bought a brand new EA4500, because I thought my old router was bad due to horrific wifi Speeds on my Wireless devices like my laptop and Samsung Galaxy S3. Well now I have the same issue with this new router.My speed from comcast straight from the modem is 25mbps down and 5mbps up, on the routers through a wired connection I get the same thing. As soon as a switch over to Wireless my connection goes from 25mpbs/5mpbs to less then 2mbps down. I've reduced the MTU, and I've tried turning off QoS. Nothing seems to work

I am using a Cisco RVS 4000 to test a new 10M/10M internet connection. I'm having a small problem performing the ISP's speed test (speedtest.cavtel.net). The download test consistently gives me 10Mbit/s, full speed for the connection, however the upload speed is usually about 5.5 Mbit/s. My ISP has been onsite and has checked the lines and tested directly, and we have determined that if connected directly we can test to full upload speeds, but when the RVS is connected, we cannot get full speed.
We've tried different cables, reseting to factory defaults, updating firmware, changing port settings, and toggling most of the other setting on the router. Some settings do have a minor effect on the upload speed, but nothing that gets me back up to 10Mbit/s.
I did notice that there appears to be no way to set speed and negotiation settings on the WAN port. Perhaps I am missing it, because that seems like a possible culprit.
Otherwise, the only only thing I can think of is a warranty return to determine if the unit itself is defective.
