Internet Fast, Downloads Slow

**rmg92uk** · 02-12-10, 12:07 AM

Here is my problem, I have a 12-18mbits per second internet speed (I think it's DSL) Now pages load fast as ever, no problems with that. But the main problem is that ANY downloads I do within firefox DL manager/Google Chrome DL manager No matter what, these downloads are slow, I mean they go from only 5-20kbits per second, which is ridiculous when pages/youtube vids/ and other things load fast as ever with a 12-18mbit internet speed. I have done the free diagnostics this site offers, but cannot figure how to edit my rwin. Also, it is JUST in browser types that it is slow, so if I use PMB (Pando Media Booster) for game downloads as is how most of the online games download, I can get up to 1mbit per second download speeds, which is pretty fast. What I want to know is why this is happening, what could possibly slow my downloads with browsers, but give them max speed with externals?

What modem do you own I'm thinking it's a modem router combo that may need some settings changed.

I could also help you out with the settings if you could tell me your operating system and take a tcpip analzyer test and paste the resaults in a new reply

I notice it says, recommended rwins, how do I edit this?

Ok, what you gave me did fix my problem with the download speed not being able to reach 1mbit/s but what it does now is goes from 2mbit/s - 1.5mbit/s, slowly decreasing down, until it hits near 50kb/s give or take a few kb/s. Do you know what can cause this?

EDIT - by the way thanks for the previous info it really did make browsing and such much faster, and DLing youtube vids and all. Just regular downloads (such as game software, for mmo's, or other softwares.) are the only problem.

**rmg92uk** · 02-14-10, 11:02 AM

I just did the knology speed test and it gave me 482 ping, 0.78 mbps download, and 0.24 upload speeds. If that helps any to know that :P. I think the ping comes from an active download though.

**mccoffee** · 02-14-10, 06:45 PM

It's buffering nothing to worry about transfers rates do that up down stuff

**rmg92uk** · 02-15-10, 06:02 PM

No, I do not think you understood that last part, my fault, I lacked explanation :P What I ment was that it goes down and stays down, never goes back up. All the way down to 20-50kb/s

**mccoffee** · 02-15-10, 07:43 PM

Are you using any firwewalls software hardware make sure you have ping allowed to get through and your ports mapped

**trogers** · 02-16-10, 02:41 AM

If upload bandwidth is choked up, download speed will fall to be near upload speed.

Are you running torrents? If so, make sure you set global upload speed limit into the torrent program to only 60% of what your ISP gives you.

Also, scan for malware to avoid them choking the upload bandwidth.

**rmg92uk** · 02-18-10, 04:44 PM

I have firewalls, but none that conflict in that way. Torrents I do sometimes, but when I'm done I shut the whole torrent client off. And you say malware, what exactly do you mean?

**mccoffee** · 02-19-10, 04:23 PM

use a program like spybot or ad aware to scan your computer both a free programs.

**rmg92uk** · 02-21-10, 11:14 AM

I have Norton antivirus, and it runs good. Do I really need ad aware or spybot? I mostly just don't want to register to their sites, which it makes you do for the download. And I just recently did a full reset of my computer, so I don't see how it could be a malware/trojan. Is there any special registry code, or protocol maybe that controls this at all? Or maybe a way to edit the browsers I use to check? I use firefox, and google chrome.

**rmg92uk** · 02-21-10, 11:05 PM

Ok, I learned what was wrong lol. Turned out I was just a tiny bit too far away from my router. It's fixed now, and because of what you told me earlier it works faster than before XD so it used to be 200kb/s now it's up to 700kb/s

Well looks as if your on Comcast cable.. what speed package you paying for? Also are you clean of spyware/malware and viruses? What anti-virus program do you use cause I see numbers that may have been changed by malware or just for some odd reason too low.

http://www.speedtest.net please visit that site and post a few speed test results from different regions of the US.

Give us that info and I can point you to better numbers that may help.

I have the 15Mbps/3Mbps Comcast cable internet package. I just recently did a recovery on my laptop not too long ago. After the recovery I renewed my Norton Antivirus. However, a week before I did the recovery my download speed was normal for my internet package, then it became really slow. So I suspect a virus in my laptop and did the recovery.

Here are my current speed tests results.

Here's my test result from speedtest.net

**Sava700** · 03-24-10, 08:56 PM

wow.. ok first off, I'd uninstall that Norton crap and put on something free that's just as good if not better. My personal preference is Avast Home Free.

Also since your running Vista the TCP Optimizer really won't do much with the auto feature it has. I suggest scanning also with malwarebytes anti-malware just to check if you have any infections.

Also you said you did a recover.. are all the drivers updated? Check with windows update to see what it finds in the way of updates as in hardware for ethernet adaptor.

Your download speed just really sucks so gotta be something blocking it and I'm thinking Norton has something to do with it!
