Very slow browsing and download speed.

by goodenough--2008 / April 7, 2008 6:03 AM PDT

I am using the Cablevision Online, but I have very slow download speed recently. I download a 15MB file with 9.xxKB/Sec - 12KB/Sec. I have tried everything from renewing my ip, scanning spyware using Windows Defender. And I also checked if i am losing any data by sending a test packet to yahoo.com . I have 15% packet loss with my router and 8% without my router.


Windows XP SP2
Pentium 4 3.2GHZ
1GB RAM
Broadcom NetXtreme 57xx Gigabit controller
Dlink DI-524
Scientific Atlanta Modem

Anyone has suggestions to fix the problems? thanks

ISP Problem?
by dougjp / April 11, 2008 10:41 AM PDT

Did you contact Cablevision, have them run through some remote tests of your connection? Try pinging them too. It might be their problem - a router, wiring whatever.

One possibility.
by NM_Bill / April 11, 2008 11:30 AM PDT

Though an Apple Mac user I recently went through much frustration. I am not technophile, but started doing a bunch of thing systematically. My breakthrough was to take a wireless router out of the loop & voila! Success. The two year old wireless router apparently went haywire. I do need to replace that because I had it in order to use VoIP, by Vonage in my case.

Lots of folks might bear in mind such a possibility.

Many possibilities look into a few of these...........

Hi There, many, many, many things can cause this sort of thing. Just because you updated the antivirus doesn't necessarily mean you are not infected oh and did I forget to mention that some of these virus checkers can actually be the cause of the issue sometimes themselves. www.avast.com has a great one free to the home user, just as a test take the one you have completely off and try that one see if anything gets better (scan your drive with it). There are some viruses that no matter what you do, cannot be removed if running on the OS drive they got planted upon, i.e. you have to pull your hard drive out and scan it/devirus it with another machine than the one it was in...sometimes viruses can hide themselves too well in the OS to be cleaned out except when inert. You might also be loaded with spyware malware, get adaware free version or one of the other ones out there and clean all the malware off your hard drive.

This can also be a bad, or going bad memory stick. If you're comfortable taking the hood off your pc swap the sticks in the slots. Most likely if you've got a marginal chip the machine won't start with it in the lower slot (marked zero or one).

When was the last time you defragmented your hard drive? Swap files can get fragmented like any other file and it will cause issues, I really like diskkeeper it's a great program and can be set to automatically keep your c: drive defragged, not too expensive at around 40 bucks either. Another thing to checks is how much free space you've got on your drive, a nearly full drive can cause some of this too.

Something running in your system tray is sucking too many resources, or you just plain need to add memory or hard drive space.

This one is reaching but I've seen wierder things, when was the last time you checked the cmos backup battery on your motherboard? I've had people tell me their machines wouldn't start or worse just because this dumb battery was weak. I check mine on new motherboards, I've found more than one dead one right out of the box.

do you have a wireless router? Could your neighbors be wardriving off you and sucking off your bandwidth? On my belkin routers I have never had a problem with multiple computers hooked to it affecting other hookups speeds but with this netgear I've got right now I have definetly noticed that stuff happening so try unplugging any other machines hard wired into your router for the moment. I know, WEP is a pita but if your neighbors are sucking your connection that's your problem right there.

For starters...
by WeirDave / April 11, 2008 3:50 PM PDT

Have you tried connecting with an ethernet cable direct to your modem? You did not mention what speed package you currently have with your provider. Assuming it is just not as quick as it was before, I would almost always start with a scan of your PC I use Spyware Doctor (For a free trial click here http://send.onenetworkdirect.net/z/11953/rn_a66689/) and clean MANY PCs on a daily basis at work using it this include fortune 100 companies all the way down to Mom and pop businesses. The average PC I ran a scan on has 200 infections. These infections can slow you down as they are trying to run in the backgriound and if your modem is a DOCSIS compliant device it is designed to prevent the spread of these infections by "closing the door to the internet" (It limits lan to wan passing) YOu also mentioned that you have a 15% packet loss. If you have the same loss when you are connected via ethernet cable then you should call your cable company and have them send a tech to check the RF to make certain fittings, splitters etc are the way they are supossed to be. Packet loss can be caused by 1! fitting and can knock a connection down to crap especially if you are trying to do voice on the same line.

Hope that helps,

Do a speed test
by Jim597 / April 12, 2008 10:29 AM PDT

Goto http://www.speedtest.net and pick a SERVER IN YOUR AREA. See if its the speed you are paying for. (1mb, 7mb, 15mb.) Dont rely on the place you are downloding from. There server might be slow. Like right now am downloading a 609mb file at 24.9KB/Sec and I have a 7mb download speed.

In reply to: Do a speed test

660 kbps download
284 kbps upload

I'm buying a 758 kbps DSL connection from AT&T.

This is an average sample for this service. Give or take, 20kbps. I'm on the maximum extent of the range for this service. My average "real" download speed for programs, videos, etc., is about 70 kbps.


This is an alternative speed test.

http://www.intel.com/ca/personal/digital-life/broadband/index.htm

Average several scores. Throw out the lows. Speeds vary.

average, 630 kbps download speed. This is a high score from this site that averages about 610 kbps.


AT&T customers might be able to link to this site.

Downloading files depend on the uploader
by victor_thai / April 12, 2008 4:48 PM PDT
In reply to: Mine is

When you are downloading a file it depends on the speed of the uploader. Try downloading from a Bittorrent file that have lots of seeds such as popular Anime. Once it gets to about 100 seeds the speed of your download should be close to your max.
Also if you are using wireless make sure your connection is secure. Sometimes your neighbor maybe using your connection as well. Therefore your speed will suffer due to 2 or more people using the same internet line.

This is a wired connection
by Dango517 / April 12, 2008 6:00 PM PDT

Sorry, I don't use bittorrent. I believe the privacy and security of it is suspect. Also the quality of the down loads using this method might create many problems in the long term. Pardon my suspicious nature but this is my opinion.

How bittorrent works:

http://computer.howstuffworks.com/bittorrent.htm

The 70 kbps download speed is "not" a problem unless the program is a very large one, 400 MB or more.

Connection speeds from various servers vary as well. Some down load servers are quicker then others.

Cable lines are both.
by donald58 / April 15, 2008 2:41 PM PDT

1st run the clean-up disk then Defrag. Do this at least once a week. 2nd Check your hard drive usage, if you are using. A FULL hard drive WILL slow tings down. ie Put 5 lbs in a back pack and walk 10mi non stop, now put 50 lbs in, put 120 lbs in. The heavier you load the slower you will go. So get rid of EveryThing you don't realy need.

Next:

Cable lines are one line with MANY many people using it. The time of day you use it has a lot to do with it.
When you download a file or program try doing it at 3am it sted of 7pm. 7pm-9pm is when most people are on line doing what they do and that line is divied 500 vr's 30-40 or fewer. The samething happens at a WIFI Hot spot. eg, 54Mbps\2 is ok, 54Mbps\10 is ssllloooowwww like dial-up.
Now DSL? that's YOUR'S & your's alone. I this because I've used all of them, and DSL had the best speed.

DSL best in your experience. I don't think that is typical.
by NM_Bill / April 15, 2008 3:23 PM PDT
In reply to: Cable lines are both.

Lots of folks have suffered through the extreme distance losses of phone company DSL. They don't rave about the experience.

Oh well, we all would like it all our way whatever way that would be. We Americans can be jealous of the much faster connections are lower price that the Japanese enjoy. Not that one wants to switch countries, especially of major cultural differences, just over computer connection. After all, it is pretty darn convenient to be American.

Yes, I whole heartedly support a regular habit of cleaning up your disks & even removing obsolete software. Defrag too, but most folks don't want to do such a time consuming procedure weekly. My half terrabyte external hard drive takes overnight to do as it consumes several hours to complete.

We all get easily seduced once having some decent speed & don't like to have to face ever going back. Sure, as the commercial says it is the same internet, but who wants to take a coffee break every time you download? Now, if only I could get connected to one of those government Lamba Rail systems.

I've noticed that about Japan too.
by Dango517 / April 15, 2008 4:20 PM PDT

Do you think that size might matter? Japans only a little larger then California. The same with Scandinavia. Whatever happened to the "Clinton" super highway?

A faster Ethernet adapter might do more good then system maintenance, unless your downloading. I'd suggest a 10/100/1000, 1 GB, Ethernet Adapter.

Whatever you do, your connection speed will always be the bottle neck of your system. Link speeds will always slow us down.

Me, I want a T1 connection, 10Mbs of pure heaven. Grin

Similar Problem.
by shaykram / April 17, 2008 4:03 AM PDT

Lateky i started having quite the same problem as the OP has..only for me it started after installing BitDefender Anti-Virus..It completly slowed down my system and my internet speed.
After a few hours i uninstalled it..but i still had to format my pc to get rid of all the mess it caused.
Now even tho i have formetted it..I'm still having "Lag Spikes".. i.e lets say im downloading something..one moment im having max speed and the next its crawling at 5kb/s (normal speed around 300k/s 2.5mb/s connection)and a few seconds later it would go back max speed. Those spikes started to show up after like a day i was running the clean harddrive.
Could it be some kind of a trojan that sits hard on my hard drive and wont go even after format? or perhaps a damaged modem or other hardware? im using cable with Voip phone.

Tnx a lot and sry for the long post.

Did you do the speed test?
by Dango517 / April 17, 2008 9:06 AM PDT
In reply to: Similar Problem.

Here's another try this one:

http://www.intel.com/ca/personal/digital-life/broadband/index.htm

Are the results from this test fairly consistent? Give or take 50 kbps, if your on DSL. What is your connection speed? Are you on Dial-up? What OS? Do you have a gadget your monitoring this with? Have you contacted your IP about this problem? What did they say? Did they test the connection from there side? You should work with them first about this problem.

Cheers
by shaykram / April 18, 2008 12:18 AM PDT

well the 1st test showed 1.4mb which is 1mb lower than my connection..but the other tests showed 2.2-2.4 which is very close to my conenction- 2.5mb/s.
my OS is XP.gadget monitoring this with?...guess not i dont even know what that means..i've contacted my ISP many times for the Voip modem problems..my ISP is new to this Voip thing and they are having many problems..i should ask them to replace my modem..it could just be te problem.
Tnx a lot for ur reply.

Try this
by Dango517 / April 18, 2008 2:57 AM PDT
In reply to: Cheers

disconnect everything connected to the Internet...... adapter, cable modem including the transformer that plugs into the wall. Let it sit for 3 minutes then plug it all back in again. Then reset/restart your modem. This will reset the modem and adapter. Then try the speed tests again.

Your first speed was low but the others were OK.

About that gadget:

http://widgets.yahoo.com/widgets/simplemonitor

This is only a sample. Microsoft has gadgets/widgets as well. You can track your DSL/cable connection with it as it's running, in "real time".

Sadly it didnt help.
by shaykram / April 18, 2008 7:46 PM PDT
In reply to: Try this

I've tried disconenct everything for like 5 minutes and restart..tho it didnt change a thing..
my main problem atm is the very low download speed..if i try lets say download anythign with my browser(firefox) it would be around the 4k..
but if i use my download manager (flashget) it would be almost at normal speed.
i wonder could it be some kind of trojan that blocks my internet even tho i formatted only 3 days ago and i have 2 antivirus programs scanning every day?

What i did was conencting the modem directly to the wall ..it didnt change a thing but when i put it back the way it used to be..connected with a long cable between the wall and the modem..it was solved.
I dont know how but i guess it was a modem/cable problem.
Thank you again very much for putting time and answering me.
Not a virus nor ISP..simply stupid cables problem..should have thought about it earlier.
Thanks again.

Glad to assist,
by Dango517 / April 20, 2008 3:09 PM PDT

that's what we do here. Pass it on.......

You might want to replace that cable and maybe the modem if it happens again. Nope replace that cable now. See ya.
