Tweaking iBurst

[Drastik]

I am glad to see that I am not the only one who is to say the least dissapointed.

iBurst is very unreliable to say the least and support is almost non existant.

From these forums and the one time I managed to get some type of a sensible response from iBurst support I have ascertained that changing the MTU is a must.

Does anybody know?
Is there an optimal MTU setting for iBurst in general or is it area and
signal strength dependant?

Are there any tools abailable that can interrogate a connection to
determine an optimal MTU setting?

Should the MTU setting be in any specific multiples? (iBurst support told me
that 1400 wont work as it is a multiple of two. The same support person
could not tell me what MTU was though so sounds like c$%p.

In DrTCP there are other settigs available, are any of these important?

MTU - The best way to test for an optimum MTU setting is to do a simple DOS Ping test.
Simply send ping requests and progressively lower the packet size until the packet fragmented error goes away!

Here is what you do:

ping -f -l 1472 www.wbs.co.za (That is lower case F and L)

Then continue testing, reducing the 1472 in unit’s of 10 until you no longer get any fragmented error messages.
Then start increasing by 1 until you reach a figure without fragmented errors. i.e. about 1422.
Now… add to this a figure 28 (IP/ICMP header of 28 bytes) and this is your Max MTU. I.e. 1422+28=1450
Ensure that the Router and ALL your PC’s now have the same MTU (i.e. 1450) setting.

When using PPPoE, your maximum MTU setting should never be greater than 1492.
If you get your MTU wrong, uploading, or browsing, may not just be sluggish… it may well freeze, or not work at all!

Please read the EXISTING THREAD all about MTU on iBurst, i.e. search for the word MTU.

cant search "MTU", please post relevant thread here

Go here (http://www.google.co.za/search?hl=en&q=myadsl+iburst+mtu&btnG=Search&meta=) first and then after that read this (http://www.catb.org/~esr/faqs/smart-questions.html). Dont take this the wrong way but its form of the initiation I recieved here.

Thank you dbnnet

stepper, i dont take it personally, but from my blogging experience, its best practice, that when you say, look at x site, or read x thread,... that you href the "x" .

secondly, i did try search as asked by ic, the the forum software doesnt allow "MTU" to be searched as the search query is too short. I didnt think to use another search engine to get the result. Consider it lesson learnt, and sorry to all readers for me contributing to forum spam....
