Very Slow DSL Download Speed

[Alex122488]

Hi All,

I'm new here, but not new to DSL. I just recently switched from AOL DSL to Bellsouth FastAcess DSL, only to have displeasure. My download speeds are very slow. At 25/kbps, dial-up download speeds, I'm confused. I was expecting speeds up to 100+/kbps. I'm not sure what the problem is. I searched Bellsouth's DSL page and called, but couldn't find out what is the problem. I'm running Windows XP. I have Spyware and Adware programs installed, thinking it would help some but with no luck. The modem that came with the Bellsouth FastAcess is Westell and I'm running the USB, as I have problems when running the ethernet. I'm not sure what could be wrong, but I'm pretty sure I'll get the help on here to atleast get a download speed of 60/kbps instead of waiting 1 hr. or more for a 100mb download.

Thanks All for your help.

Please take a tcip anlayzer the link is below me cut and paste everything below ip infomration in a new reply

Also did you remove all the aol protocols and software in my computer control panel network and dial up connections also in add/remove program??

To be honset if you haven't done those removal i admit this sounds drastic you might be better off doing a back up and format the drive and reinstalling windows aol is very very blotted

MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

For optimum performance, consider changing RWIN to a multiple of MSS.

take another analyzer test after you do thease settigns your mtu is off

Try thease in the sg optmizer below me to download and install
select - cable
check - custom settings
network adapter selection -
check modify all adapters
maxmtu -1492
TTL - 64
TCP Receive Window leave blank
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 windows scailing is checked
Other Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
Lan Browsing Speedup - optimized
Then select "Apply Changes" and reboot to take effect.

1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

2. Open IE and select tools - internet options - connections -
LAN settings, make sure NOTHING there is checked.

3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with SpyBot 1.2 http://beam.to/spybotsd & Ad Aware 6.0 http://www.lavasoftusa.com/support/download to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.

7. Make sure you do the faster web page tweak in Read1st link.

8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.

9. Install Outpost Firewall http://www.agnitum.com\ or Sygate Firewall http://www.sygate.com/ , both have FREE and Pro versions and are heads above ZA.

10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, AVG 6.0 http://www.grisoft.com/us/us_dwnl_free.php is an excellent FREE AV app.

11. Make sure you have ALL of the latest Windows Updates

hello. newbie here.

i had the same excat problem as apparantly alot of other people. my bellsouth dsl was below dial up speed. after 3 weeks i just reinstalled my cable modem and everything is fine for me. hope you have a happy resolution with your problem.downloading at 25 kbps is just not acceptable,no way i'm paying a company to give me sub dial up speeds.

I just moved from my apartment into a house I purchased. The DSL speeds here are VERY slow. Using Verizon's SpeedTest (http://infospeed.verizon.net) I am getting "1x ISDN 64.0K 119.4KBits 14.9KBytes "

Verizon told me that the problem was my modem after being on the phone for hours and 2 days of Tech's coming out to my place... but, I am using a new modem and still the same problem. I had VERY fast speeds at my apartment. I was downloading files at about 200k per second. Now I am lucking to download at 10k.

I don't know what to do. Any ideas? Anything else I should check?

Thank you

Hi eddieturtle, welcome to our forum. Please start a new thread so that we can assist you exclusively.

Please let us know who your ISP is and the speed you pay to get.

What speed are you getting?

You have just moved into a new house, is the telephone wiring of the house old?

Also, do and post the TCP Analyzer test.

here are the results of the analyzer

do you have any ideas of how to optimize the connection

Internet Speed- 100mbps
Download Speed- around 20kbps
ISP- CenturyTel

[mccoffee]

I would double chack you phone bill and find out what the speed package is on your dsl plain.

i could be wrong that 100mbs is the local speed not the speed of your dsl.

Reply back with the advertised speed ,and also modem model# we'll get ya fixed

[Valefore Knight]

Im not able to find my bill right now, but I do believe that the dsl speed is 100mbps.

The router is a Westell Model # E90-610014-06

Then the router goes into a Linksys Wireless-G Broadband Router Model # WRT54G

Log into your Westell and go to the section for connection status and tell us what download and upload line speed it is getting from your ISP.

If your Westell is not set into bridge mode, you are double NAT - 2 routers connected back to back.

[Valefore Knight]

I have to go to work, but I will most likely post tomm.

when i use download accelerator, speed can reach 120kbps

your tcp/ip protocol my be compromised by a virus, malware, system error or other, try this

Download speeds depend on a variety of factors and that includes the speed of the server from where the file is coming. See these tips to know more
