Frustrated with Reliance’s NetConnect, I jumped with joy when I heard about BSNL EVDO. Can anyone beat the 2.4 MBPS speed, that too with unlimited download and everything at just Rs. 750/- per month?

I got my BSNL EVDO Device through an agent [Device cost, Rs. 3640] and because of the delays from the agent, it took me three days to see the device. Being a techie ( :p ), I installed the driver myself and got it running. The agent left and I started checking the speed.

Now I never got speeds more than 5-6 kbps 🙁 but I was not ready to give up. I searched the whole Internet for fix and found out couple of solutions – which did not work. So finally, I found out a simple fix for the BSNL EVDO speed booster on VISTA:

1. Install the latest EVDO Dialer from ZTEMT Official Website:

It worked for me. 😀 The speeds are now blazing fast 😀

Let me know if this works for you.

2. If the above does not work, I’ll also recommend performing following steps on Vista:

  1. Click on Start -> In the search box, type “command prompt”
  2. On the command prompt listing, right click and select “Run As Administrator”
  3. Click on ‘Continue’ on the hideous UAC popup.
  4. On the command prompt, type: netsh interface tcp show global
  5. See the status of Receive Window Auto-Tuning. It would be something like “highlyrestricted“.
  6. To change it, type: netsh int tcp set global autotuninglevel=disable
  7. Verify the status again by executing the command in step #4 above.
  8. It should be ‘disabled’.
  9. Done.

Restart your computer and check the speed again. Happy EVDO browsing 😀

    How much speed are you getting now?

    I’m planning to go for BSNL EVDO, as BSNL broadband isn’t very good.
