Cable modem reeeeeaaaalllly slow

[facefirst]

I have Cox High Speed internet and am running on their typical modem. I went to speedtest.net and I'm getting really low speeds. Here's my most recent test:
http://www.speedtest.net/result/183556033.png (http://www.speedtest.net)

I would imagine that it's so slow because of it being peak time but even during the middle of the afternoon it's only running at about 1500mpbs down and 700mbps up.

Here's my TCP Analyzer results:

Is there anyone here that could help me out? I can't imagine that these are normal speeds for cable modem. If so, maybe I should look into downgrading to DSL.

Try the following with TCP Optimizer:

Modify All Network Adapters - check
network adapter selection - your NIC
MTU 1500
TTL - 64

Then select "Apply Changes" and reboot to take effect

COX Internet is bad. Comcast is great.

Comcast is deliberately blocking torrents.

Thanks, trogers. That seemed to help quite a bit

I'm not even sure if these numbers are considered satisfactory or not. I'm a noob at this stuff. It's one of those things that I didn't think about until there seemed to be a problem.

Try these to see if you can get close to 6 mbps:

Post your TCP Analyzer report to see if settings are correct.

[facefirst]

I actually reverted back to the settings that you suggested before but here's the current settings. It seems to be running slow again.

Man, this is frustrating. Thanks for all of your help.

Problem may not be in the settings.

Do a tracert to www.yahoo.com and post.

To do a tracert, click 'Start' and then 'Run'. Type "cmd" into the box and click 'ok'.

A DOS black screen will appear. Type after the C:\>

tracert www.yahoo.com

and press enter key

When test is completed, move mouse cursor to the DOS black screen, click right and choose 'select all'.

Move mouse cursor to the Quick Reply box of this forum, click right and 'paste'.

Turn power to your modem off for 5 mins and relocate it a few feet away from all other electrical devices. Make sure you do not coil up any excess length of signal or power cables.

Power on again and check speed.

What is the brand and model of your modem?

[facefirst]

Terayon
TJ715x

These test have all been from my laptop.

i noticed on my desktop (which is connected directly to my router) that I get 4559 down and 541 up speeds.

[trogers]

Click this link: http://192.168.100.1

Try Username = admin and Password = admin or password or terayon

When you can log in, search for the status of signal power levels and compare them with those at this thread:

There' no login it just goes to the modem info center. There's also no status section.

If your laptop is the only comp showing uneven speed, try scanning for possible spyware.

Search Google for the following free programs:

SpyBot
Ad-Aware 2007
a-Squared Free

Also, use CCleaner to scan for issues and clean the registry.

Best to turn off System Restore before scanning:

Control panel -> System -> Tab to system restore and set accordingly.

i've already scanned and it's clean

Is your laptop connected to the router through a wireless connection?

The IP address of your router at hop 1 is not in the format of 192.168. xxx.x

It may have been set into bridge mode, which is not ideal as it then is no longer acting as a router.

[facefirst]

Yeah, I use a wireless

I ended up changing the channel on my router and now it's hitting about 7 mps.

:thumb: Good speed. Check to see if you are paying for a speed even higher than that. If so, let us know so that we can increase TCP Window to suit it.

[facefirst]

I'm paying for up to 15 mbps, actually.

Tweak your desktop with the same latest settings and test its speed.

duh! I'm an idiot. Sorry.

I think your ISP is giving you the 10 mbps speed package, not 15 mbps.

[facefirst]

That's weird. It says up to 15mbps on their site
