Cisco Switching/Routing :: Slow Upload Speed Behind 2811 Router?
Mar 10, 2013
I have working internet behind cisco 2811 on all vlans however upload speed is very slow and ftp server download is slow and times out, previously when directly connected to modem/router was fine? This is router config below:

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.

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 bought an E2000 router as a replacement for my WRT54G router, since my internet speeds had been upgraded. But this E2000 router has been giving me nothing but trouble.
Wired through both the router or modem, I get my topspeed of 110mbps. However, as soon as I switch over to the wireless N function, my speed drops to only 25mbps. As far as I know, wireless N should have a much faster speed than that. Even my old WRT54G had faster speeds than this new router has. Mind you, that the distance between my laptop and router is about 3 inches away. The further I go away from my router, the speed exponentialy drops (20 feet, and the speed even drops to below 10mbps). Even with different laptops that have completely different wireless cards. Now honestly, I have tried EVERYTHING to get the speed up. Both 2.4 and 5ghz, 20mhz only, 40 mhz only, different channels (currently the router is in channel 11, being the only router in that channel), setting the network to G-only. I tried changing the Beacon interval thing in numerous settings, I even tried changing the MUT. Firmware is completely up to date. I have also tried placing the router on a completely different place, to make sure there was absolutely no interference (tough that shouldn't be an issue if my laptop is only 3 inches away) I tried changing the security mode to something different than WPA2/AES.
Nothing worked, if anything, it made it worse in some cases. I have litteraly tried every option I could find online, except for trying a third party firmware like DDWRT, which worked excellently for my old WRT54G, though I read that speeds can't be improved on this E2000 with a third party firmware.
Is there anything else I can do, or should I assume that my router is defective?
When I'm in my bedroom, I get a very poor connection and my speed drops to about 0.25mbps. Abysmal, so I bought a WiFi range extender to get me a better signal. It works, and it allows me to get a speed of about 5-6 mbps, without dropped connections. Still slow, but at least it works. The weird thing is, wired through my router or modem, I get about 9mbps upload speed. With this extender, I get the same 9mbps upload speed in my bedroom, though only 5-6 mbps download speed. You'd think that the upload speed would drop simultaneously with the download speed. How can my upload speed be higher (maxing out) than my download speed? I wonder if my transmitting antenna of my router isn't defective.

I Have BT Infinity and they are pushing 70mbps to my house ....i bought an EA6500 and i had real bad internet speed but amazing conection speed with my BT Home HUB3 ... 23Mbps with Cisco EA6500 and 68Mbps with my BT Home Hub3. I found out it was the Media Prioritization so just to be safe i reset my factory settings and made sure it was turned off. Just like magic i get the same now as the BT Home HUB3 .

This is the first PC I have ever built, but I built it with a buddy who is very experienced and everything went okay. The computer is maybe 3-4 weeks old now, everything is running fine, until today when I decided I wanted to try streaming some Diablo 3.This is when I discovered my upload speed was absolute garbage.I have verizon FIOS - I pay for 15/5, the download speed is always at 20+ mbps, I have never had any problems with it., but my upload speed is fluctuating between .34-1.5 mbps, changing every second.I know this is a problem with the computer because I brought in my old laptop, unplugged the ethernet from my new desktop, plugged it into the laptop in order to keep all variables the same, and it was getting 25/5 without any hesitation.When I was downloading the drivers for my mobo I installed something called Windows Firewall with Advanced Security(maybe that was with a windows update, im not sure).
Specs of my PC (if this matters)
-Asus P8Z77-V LK
-8g ddr3 Ripjaws
-i7 2700k
-Corsair H60
-EVGA GTX 670
-Crucial 128g M4 SSD
-Caviar Blue 1TB HDD

9x3750E stacked switch (WS-C3750E-48PD-SF0) (15.0(1)SE2
C3750E-UNIVERSALK9-M)
2x10Gbe uplinks from EMC NAS
At a basic level, we have found that the 10Gbe uplinks have slow read performance with or without a port-channel configured (2-3 minutes for a 700MB file to desktop from the NAS) We switched back to testing a 1Gbe and the read speed is normal. Another anomaly is Win7 / 2008 machines read speed is fine from the NAS while the 10Gbe uplinks are in production?!
Write speed is great on 10Gbe. Only read speed is affected!! the switch is not reporting anything abnormal. We looked at SMB/SMB2 as another possible cause...
mls qos is enabled on the switch but not sure if this is affecting performance.
Is the ANY config that I need to carry out on the interfaces to get the read speed working as it should for both Win7 and WinXP. (MTU is 1500 throughout the enterprise, NAS included).

I am getting very slow window file transfer speed (4 Mbps per second) between two connecting servers in Cisco 6509 switch. I have connect the two laptops in 6509 switch in same module using the same vlan and try to copy the files from one laptop to another and vice versa and got the same speed on 4 to 5 Mbps per second. Switch utilization is not more than 10% and both the laptops are connected in 1 Gbps full duplex.
I have checked by removing the gateway in both laptop but the output is same.

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 by a dual channel router, can all wireless devices pick up on the 5GHz spectrim and if some, 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?

I upgraded my old router to a Linksys E1200 about 2 months ago. Like others with Comcast, I now have a lot slower internet speeds. I've updated everything, disabled WMM. I'm still getting slow speeds. My download speed is 3.12, which is not that bad for me. However, my upload is just below 1.

This issue started about 6 months ago. I have noticed the following issues:
1. I cannot download large files. It starts downloading then it stalls.
2. I cannot download videos on Youtube and other video site to stream the video. In [URL] the test shows 100% complete but the test keeps on running and upload speed goes down.while running the upload speed test on [URL] sometimes it cannot connect to server to upload the file. When it connects to the server I get error saying that it cannot read the file it uploaded.Had Comcast come out to take a look at the cable and they claim that it was the PC's fault and not the cables's fault. I have the cable coming out of the modem to a linksys router ( WRT54G), then to my PC. I connected the cable directly from the modem to the PC and still had the same proble.
I have the following:
System
Manufacturer: Velocity Micro
Model: Edge V420
Processor: Intel core 2 Quad CPU Q9550 @ 2.83 GHz
Memory(RAM): *.00 GB

Since we purchased our router in February, we've had intermittent problems with speed, and now it seems to be permanent. If we connect directly to the Comcast modem, everything is fine. If we connect to the router, directly or wirelessly, speeds drop to <3.

I have four E4200's doing the same. I have FiOS 15M download and 5M upload. As soon as QoS is turned on the upload speed drops down to usually 300k and it never exceeds 1M.At the same time any VPN connection gets dropped often.I also configured one E4200v1 as router and the second E4200v1 as Access Point (HDCP off) hardwired to the first one.Any VPN connection gets dropped when changing location. I.e. if VPN was established with the router, the connection gets dropped when in the location where AP is -- and the other way around too. There is no coverage gap between the two locations, to the contrary - they do overlap heavily.On Dec 21, 2011 the level 2 Linksys/Cisco people advised that they will forward the two issues to engineering and that resolution will be within 24-48 hours.

Download speeds, per speedtest.net and speakeasy, are about 20mbps.When the speed test gets to the upload part, it usually hangs or takes a long time before giving me a result of about 0.04mbps. Basically, it's so slow, it sometimes just gives up and times out.This translates into a real shoddy internet experience because something as simple as choosing airline tickets requires your computer to "upload" your choices. And of course, if that doesn't happen within a certain amount of time... Timeout! I have tested the connection without my Netgear FVS336G Dual WAN router in the way and it is much better so I'm certain it's the router.When I tell the router to use WAN 2, which is where my AT&T DSL connection is on, the upload works just fine (about .4 mbps - I'm provisioned at 512kbps so it's fine).Also, this is the case on ALL computers on the network - wired, wireless, PC, Mac, iPhone, iPad, you name it. So, it's definitely not device specific.

I have a Cisco 2811 Router. I have two VLANS on the router. The first one of course is VLAN 1 and the second one is one that I created from reading everything from this forum.. it is called VLAN 531
On VLAN one I have an IP address of 10.8.1.1 and on VLAN 531 I have an IP Address of 172.16.1.1, now what I can do is this... I can.. from a workstation on the 10.8.0.0 segment, ping 172.16.1.1 and one server on that segment that has an IP address of 172.16.1.50, which is fine, but what I really want to be able to do is ping our email server which is on a 10.21.0.0 segment and I cannot. Any commands on what I would need to do to make this work as I would like the 172.16.0.0 segment to ping any other part of my LAN of my choosing.
