Cisco Firewall :: Slow Upload Speeds To Internet Behind An ASA 5520
Aug 23, 2012
Our internet connection is connected to an ASA. The download speed is ok but the upload is very slow. we have been running some speed test from our LAN, and have been also trying to upload/download file.
Our ASA also have the IPS module. I turned this off but we've got the same result.
I send here attach the configuration file of the ASA.

I have two 5520s in a failover configuration. When browsing the internet behind them the speeds average 0.5Mb/1.0Mb Download/Upload. When bypassing the ASAs the speeds increase to 4Mb/6Mb. I have checked the interfaces on the ASAs and there are no errors, collisions, drops, etc.

I did a search and came across this board because I too am having the same issues with wireless connection. I went as far as buying a new router, which like the original post stated, worked well for a few and then stopped. It's frustrating because I need the wireless connection for many items I use at home.

I just built a new computer with most of the bells and whistles. Asus P8Z77-V pro motherboard, Intel I7 3770K CPU, NVIDIA GTX 560TI, SSD for my boot drive, HDD for storage both running on SATA III, 16 GB of RAMMy problem is that when I connect to the internet via an ethernet cord, my download speeds are about 58 MBPS which is fine but upload speeds are only about .3 mbps. I have changed cables 3 times and connected directly to the modem rather than the router which would indicate an ISP issue. The kicker is that when I disable the LAN network and enable my wireless network, I get slower download speeds as expected but my upload speeds are closer to 5 MBPS, more than 10X times faster which throws my ISP theory out the window a bit.

I'm having really slow speeds surfing the internet, watching videos on sites like youtube, and downloading files. So i went to [URL] and found that my download speeds are only 1.3 mbps!! my upload is fine, around 5 mbps.I am wirelessly connected to the router, but the signal strength is fine.

We recently bought a home and just moved in. That being the case, we got a new ISP (Cincinnati Bell DSL). The service is advertised as "Up to 5Mbps."
My current equipment:
PC:
OS Name Microsoft Windows 7 Home Premium
Version 6.1.7600 Build 7600
Other OS Description Not Available
[Code].....
So what can I do to achieve faster speeds? Am I limited by the hardware I have? My Dell is roughly 6 years old. Am I limited by Cincinnati Bell? Is it the location of the wireless router? Are there settings I can adjust to create a faster connection?

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.

i recently switched from a wrt54g to a Cisco e1200 and my average torrent download and upload speeds went to 1200/kbps 100/kbps to around 200/kbs 0-1/kbps i got the latest firmware tried different channels disabled the wmm I've also tried wireless n only and wireless g only. I have no way to test the wired speed. I have a n adapter.what do i do.

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.

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.

After recently intalling the WMP600N wireless adapter I have had great trouble getting it working properly.
Current performance
- signal: verygood/ excellent
- download speed: ~1mb
- upload speed: ~2mb
- signal speed: 18-54mbps (lots of variance but never above 54)
Comparison to my laptop
Laptop in same location with wireless G capability
- signal: verygood/ excellent
- download speed: ~20mb
- upload speed: ~2mb
- signal speed: 54mbps
my router is a D-Link wireless N router I recieved from my ISP. I do not believe my router is to blame for this problem since I have a laptop with an inferior wireless adapter recieving 20X the download speed.Drivers I have installed the latest drivers for windows 7 and I am running windows 7 Ultimate 64bit.

We have an ASA 5510 and are experiencing unbelievably slow speeds. I noticed a problem last Thursday with users complaining of slow speeds and realized our interface had a ton of errors and was running at half duplex. I contacted the ISP (we are connected to their 3750) and they swore up and down they were set to full. So they had me switch to full and the interface shut down. I asked them to switch to auto and the interface came back up and we went to full, and of course the errors and colisions stopped. However the errors and packet drops have not stopped. The ISP sent out a technician and they determined it wasn't a problem on their end by plugging in a laptop and testing the speed--that worked fine. Eventually I plugged in a Sonicwall and bypassed the ASA completely and that worked fine. We plugged the ASA back in and we we went back to dropping packets. I put an old config on the ASA and oddly enough it seemed to have fixed the problem but we were still dropping packets. So I put the most recent config back on and that worked fine up until today. We're back in the some boat we were last week. So my first question is when I do a show int and see packets dropped - is that normal because of ACLs etc, or would that be show in another place? Here's an output of show int and show asp drop:
HQ-ASA# show asp drop
Frame drop: Flow is denied by configured rule (acl-drop) 3366 NAT-T keepalive message (natt-keepalive) 423 First TCP packet not SYN (tcp-not-syn) 406 TCP failed 3 way handshake (tcp-3whs-failed) 135 TCP RST/FIN out of order (tcp-rstfin-ooo) 462 TCP SYNACK on established conn (tcp-synack-ooo) 46 TCP packet SEQ past window (tcp-seq-past-win) 50 TCP invalid ACK (tcp-invalid-ack) 9 TCP Out-of-Order packet buffer full (tcp-buffer-full) 29 TCP Out-of-Order packet buffer timeout (tcp-buffer-
[code]....
I have not made any configuration changes to the ASA ina couple of months. The interface counters were cleared about 45 minutes ago if that's how quickly the errors/packet drops are adding up.

My Belkin F7D4301 Router has the fastest wireless speed of maybe 2MBps but wired with a cat5e cable to my asus laptop of almost 7MBps. I have a one smart TV, one blue ray, one roku, and a nexus 7 using the 2.4 channel.
My Wireless 2.4 settings are channel 11, Extension channel 7, Wireless mode N (have tried with just g and b, g, and n modes), Bandwidth 20/40, Protected mode on, QOS off.
I've talked to Belkin tech support, they are the ones who had me set up my 2.4 channel this way but my wireless speeds stay just under 2MBps, they just want to keep sending me the same model Router because they think each of the new ones they send me is defective.
Am I doing something wrong or is 2MBps the best wireless speed I'm going to get?

I live in a townhouse in a college campus which means we all have the same ISP. I checked the channels and checked wifi stumbler. They both look good. For the last few days I have been getting really slow internet speeds after 7 pm till 1 am. I am paying for 25 mbps but around that time I get 0.5 mbps. I have the latest firmware for the router. I talked to customer support twice and all they did was reset my router and tell me to power cycle it. It can't be range of the router because my laptop is right next to it.
P.S: Here is my speed test: [URL]

So I've noticed a big speed drop in my comcast internet. I went from routinely scoring over 20mbps on speedtest.net to around 11. Also, the upload test fails everytime. On every speed test site I've been to, the upload test completely fails. I haven't changed a thing so I have no clue why this would happen, but maybe it might have something to do with the speed decline.
I have an old WRT54G router that I've had for almost 10 years and I was thinking that maybe that was the problem. So I tried directly connecting my modem to my rig, but for whatever reason, I couldn't get it to work.
I can build unbeatable gaming rigs and program like crazy, but I just do not have networking in my skill set. It confuses the hell out of me and always seems to be completely random. What I can do to isolate and resolve my problem?
Oh, on one of the upload tests I got the following error.
"Trial measurement failed. Client can't send/receive UDP packs to server port 8601".

The speeds for my internet connection seems to vary significantly. For most of the day I have checked the speed of my internet from various websites such as speedtest.net, speed.io, speakeasy, 2wire, etc. The upload speeds are fine and are close to the advertised 4 Mbps upload speed that I am paying for.During the early afternoon, the download speeds are around 15 Mbps and start to slowly decline until it reaches 1 Mbps at around 9 PM. This has been going on for months and I pay for 30 Mbps download speed from Charter. I've checked this on three different computers throughout the day and they all read the same thing. I don't know if it's a problem with my router or a problem with the wiring in the house. the modem/router I have right now is a Motorola SBG941. url...

I'm currently subscribed to Comcast's 22/5 Internet service. Internet upload speeds on both wired and wireless are about the same at ~ 5 Mbps. Wireless download speeds range from .5-3 Mbps. Wired or Wireless, I receive LAN speeds of ~32 Mbps or 3-4 MB/s. The noticeable issue is wireless internet download speed. I have tried every configuration possible with my router, updated drivers on devices, firmware and tested everything I could on all PCs, and even used the XBOX 360's media extender network tuning feature as a tool in my investigation to find this bottleneck. All reports point to internet download speed. Again, general LAN and internet upload speeds relatively meet expectations. The wired download speeds are slow at times, but consistently meet expectations.
My current Setup:
Wifi
A4 1.33NA
WPA2 Only - Personal
802.11 Mode : 802.11n only
Channel Width : 40MHz
Channel : 1

I am only getting 10-14 mbps when I should be getting 30-35 (using the gigabit ports). I thought it might be my provider but today I connected my old netgear router and the speed was 32-34 mbps. Is there some setting that I should be looking at?

I have a synchronous 10 Mb connection to my isp which I have conneted to a CISCO asa 5510. I have done a lot of testing and there is a very noticable difference in my upload/dowload speeds.When I connect a laptop directly to the Cable from my ISP's equipment and have the NIC set to autosense, I get similair results for Download/Upload Speeds I have tested and get 9 plus down and 8 plus up.When I either connect the asa directly to this cable and set to either 100/Full or autosense OR I place a non-managed switch in between the asa and the ISP's equipment My upload speed drops dramataically. The Download speed stays about the same 8 Mb Plus but my upload falls off the face of the earth drops to about a 1Mb. I have noticed this many times when I am going from a cisco 800 series router to a Cisco ASA.This is severely limiting my ability to perform replication out from my locale.

I have a RCA modem from comcast high speed internet.Also have a Linksys Cisco Wireless-N Gigabit Router model # WRT310N V2. When I connect the internet directly into the computer, I get download speed up to 21.07 mbps and upload speed of 3.07. When I connect through the router download speed 1.31mbps and upload speed of 1.01.I have no clue how to make changes to the router.

I have recently had trouble with my wireless D-link WBR-1310 Router. Two days ago everything was working fine, my wireless connection from the router to my macbook was fine and the wired connection to my desktop pc was also fine. I went to bed and when I woke up the next day everything was still ok. About 3 hours after I had first turned on the PC that next day my wired connection started spiking and dropping connection frequently, maybe every 5-10 minutes or so. I play world of warcraft and I also use Mumble VoiP Program and my pings in both are over 800 constantly now making it impossible to stay connected to either program. Sometimes it will drop down to regular numbers (25-50ms, I play on eastern servers as I am in NY) but then rapidly jumps back up into the 1,000's. My wireless connection is still fine though nothing has happened to that, only my wired connection is messing up.
I've tried changing my speed and duplex settings on my onboard NVIDIA nForce 10/100 Mbps Ethernet which is what im using but it hasn't worked. When connecting directly through the modem the problem seems to stop so its definitely the router.
Wireless Router: D-link WBR-1310

I just upgrade my service with Comcast so I can now get up to 50Mbps, however the modem when directly connected to the PC can obtain these speeds, it does not when the PC is connected to the E4200 router. In fact the Cisco Connect speed test shows the upload speeds (10+ Mbps) to be faster than the download speed(4.82 Mbps). I upgraded the firmware to the latest level but it did not make a difference.

users behind asa5510 on both vlans10 and 20 have slow internet speeds (2Mbps down/170kbps up). carrier provides 13Mbps down/5mbps up and speed tests on another port on the asa 9Mbps/5mbps. There is no speed/duplex mismatch on the switch (cisco 2960) that asa port is connected to. what else could possible cause that ? cisco 2960 is in vtp transparent mode. mtu on both vlans is matched.

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

I have a PC with an onboard Realtek 8168 PCIe Gigabit connected to a D-Link 655 Gigabit router.Here's the odd situation: when speed/duplex is set to 100Mbps, my upload speed using www.Speedtest.net is fine (~3.0 Mbps). However, when I switched it over to 1.0Gbps, it goes down all the way to 0.06 Mbps. Download speed is generally unaffected. can't tell which is the likely culprit!
Onboard NIC faulty/underpowered?
Faulty cable (highly doubt, I've tried 5+)?
Or is it a matter of settings? I turned off QoS and WISH on the router, but it didn't do much.
