Hello all,
I am not sure if what i am suggestion here has been discussed on this forum as I have personally not seen it. But hope it helps those of you using BSNL EVDO in Vista. My understanding of this tweek is that it will work with other providers such as Tata and Reliance that also provide EVDO / CDMA based services but do not have either so cannot comment on this.
Have just signed on to this forum but have been tracking many threads under the BSNL EVDO forum.
I have been using BSNL EVDO over the last 12 months cause I thought it was a great value at Rs 500 / month for unlimited internet. Initially the speed was great and I was downloading at 100-150kbps in bursts which was better than my Airtel BB 512kbps connection.
However in a couple of months the speed dropped drastically to max 10kbps max when downloading. I am assuming this was on account of a bunch of users that got signed up after me. I tried in vain looking for tweeks to spped up the connection.
I tried everything: DrTCP tool, Windows vista KB tweek, updated drivers from ZTE website, Custom drivers.. Nothing.. Absolutely nothing seemed to work to increase the speed.
I was about to give up when i accidentally stumbled upon a tweek while driving on the highway where i was getting only 1x signal but am absolutely amazed at the speed.
I found a website ::. Kitz - Vista TCP tweaks .:: which addressed the "Receive Window Auto-Tuning" feature in Vista being turned off. Disabling (or setting to normal) the Auto tune feature seems to have improved the perfomance drastically.
It was simple as tying the following command while running CMD as Administrator.
Click Start -> All programs -> Accessories
Right Click on Command Propmt and click "Run as Administrator"
Authenticate and then type the following line.
netsh int tcp set global autotuninglevel=disable
To verify the status of Receive Window Auto-Tuning you have to type the following line in cmd
netsh interface tcp show global
My system was set to "highlyrestricted" before i disabled the feature.
I tried it and was pleasantly surprised. Even without the EVDO signal, the ZTE software was showing 1x signal, I was downloading a movie at 200kbps (20kBps). Again this was on the highway with the car moving at 100kmph.
Turning off the TCP recieve window autotuning feature, it feels like the EVDO finally responds and very quickly at that. I used to have max 2 minutes of great speeeds and then the connection would almost go dead on me. Now it works great even after a couple of hours.
It will be great if other users in Bangalore and rest of India could try this and let me know if it works for them. I dont understand the minute technical details of why it worked for me. SO will leave it to one of the experts.
Disclaimer: I am not a programer / network expert but i tried this. Please try this at your own risk. Otherwise it would be great if one of the admins o an experienced user could comment on this method and its effects.
