Using Toonel ?

**Angelinedev** · 09-29-08, 05:06 AM

Malaysia , yeah im using toonel,i was going through the beginners guide and i find toonel really important cause my IP limits me to 5gb a month of downloads. BUT toonel slow my connection extremely , when i utilise toonel , my browsing is super slow ,i followed all their instructions yet its terrible...is this common or did i do something wrong...

**Angelinedev** · 09-29-08, 02:24 PM

The TCP Settings are correct.

Post your speed at Singapore server and several servers near by.

Hello Angelinedev..

1. That's the nature of an internet connection over a mobile phone line. Much depends on your distant and clear line of sight to the cell tower and the clarity of the airwaves.
2. What Signal do you got on your Mobile Connect dashboard and how much signal bar?
3. At the tray icon you can see Status HUAWEI Connection, double click this and see the Speed: ?Mbps.

**Angelinedev** · 10-02-08, 04:56 PM

This is when i changed the TCP window ,just experimenting...any comments? not sure what im looking for =[

If you are experimenting, after ever change you should also do at least one speedtest to see if it is any different. Probaly run three speed tests and compare them.

If I were doing this, I would test at least two times at each TCP Window setting at different times of the day. Once when there is low traffic and once when there is high traffic volume.

Record: Time of day, TCP Window used, and Speed tests results.
You would probably also want to check the TCP Analyzer Results to see if they change.

Where do you put your modem ? Near electrical devices ?

**Angelinedev** · 10-07-08, 02:44 PM

well my pc is beside my TV , and my stereo system and also my satelite decoder.. my modem is right above my cpu,cause the cable is short.

**Angelinedev** · 10-07-08, 02:52 PM

this tracerts that im posting is with the TCP window of 256960,i read the one of the posts if we set TCP window too high it will slow down the speed.so i just set it back to 256960.Should i do a tracert with TCP Window: 513920 ?

Anyway below is a tracert after pulling my modem as far as i could from electrical devices

this is a tracert after further pulling my modem away from equipment,it basically cant go any further. I also changed my TCP window to 513920. Below is the analyzer results :

My average download speed after 3 tests was approx 1500 kb/s , my IP max is 3.6mbps.Should i keep my TCP window at 256960 or 513920? Is there an improvement for the tracert?

As you can see the 'Request timed out' in the tracert, that's the nature of mobile phone line connection. Show your ISP this tracert and see if they will help !

I'd use 513920 for TCP Window value.
