I had availed DataOne connection, Chennai last month. I came to know of this forum only today (29-May-2005). Here goes my experience with Dataone:1) Right from day one after getting connected, I was unable establish connection. Reason being, I used to encounter Error# 678. I had logged a complaint with the call centre (1600-424-1600). They were kind enough to hold the complaint pending for almost a week. I approached our local exchange and informed about the situation. The lineman visited my house and identified the problem is with their lines (telephone cable). This was tracked and changed. I was happy to know that, I would be able to establish 24x7 connection. It all started after 1 hour of rectification --- the same old Error# 678. The whole process started again - round robin of course!2) Weeks passed and the complaint was raised to CMD of BSNL. One woud not believe the response I received. The whole of BSNL authorities called up and assured that they have pressing reasons to resolve this issue. Wow! so good to hear, I thought.3) Broadband Customer Service manager's visit to my house was welcomed. He started his analysis for the error# and declared that I have a very cheap network card installed (I have Realtek RTL8139). Also, he advocated me to go for IBM or Intel cards as he has one in his laptop. He was kind enough to configure the connection settings in the gateway itself. This would avoid me to click network connections.Well, to defend, I had to inform him that he had onboard/ PCMCIA card which is not the case with me. As I had to install the card separately, my engineer opted for this (well used in the industry) card.4) Things remained same even after a month. Now, I am not encountering error# 678 rather I would encounter page cannot be displayed. Reason being, the connection settings is configured in the gateway itself. However, I am able to connect to the internet on some specified timings and not whenever i need to.5) When I checked the gateway settings, I see that the gateway gets assigned an IP and I am able to ping the same. But I am unable to connect to the internet.6) Now, I am planning to downgrade my o/s from Windows XP pro to Windows 95/ 98 and see how it behaves.7) If it still remains same, the I am planning to surrender.Any thoughts from your side is welcome.Thanks,KVN
