Thread: BSNL 8mbps? or higher?

Why post bmp image,convert it to jpg and you can get it below 100 kb easy.

"image posted is 88.7 kb"

Signed up for 8 Mbps. Should've started to get it from 12:00 a.m. However, the plan changed to 15000 in the control panel - yet to see any difference in speed though. Line speed is still at 2048/256 kbps.

i am still getting 4-8Mbps speed.
here's what i found. i don't know anything about this. the significant change is that during normal bandwidth(250-359Kbps) the statistics shows ADSL 2
but during 4-5Mbps speed it shows G.DMT
If any one of U could interpret these statistics please explain.

If any one of U could interpret these statistics please explain.

my guess is that some upgradation work is going on in your area for launching IPTV for which 8mbps speed is must.maybe they test the IPTV service at these times & that is why your modem automatically gets the high speeds because it syncs with a much faster rate.

i have bsnl iptv and my downstream/upstream is 6142/640 .. so i guess its 6mbps!!

it also depends on whether bsnl is using some software to restrict users from getting more than 2mbps when such tests are carried out.if no such policies are being used at the local exchange then users may get high speeds because i have seen users with 8mbps line rates in their modems & still getting max download speeds around 1.9mbps.

But U havn't ansered my question

during normal bandwidth(250-359Kbps) the statistics shows ADSL 2
but during 4-5Mbps speed it shows G.DMT

cuold anyone tell what is G.DMT.
also i'm getting this speed (4Mbps) constantly for the past two days.
though browsing speeds are fast, firefox shows that files are downloaded at 70KB/s, though i just tried for a small file.
i also in a way found out how to get stable 4Mbps speeds(but i'm not sure)
in ut300r2u modem
192.168.1.1 and type username password
go to advanced and click on dsl
in it uncheck ADSL 2 & ADSL 2+. check whether G.DMT in ticked. save.
save and reboot. done
I'm just a beginner. only experts who know about it try it. but i don't think it will be of any harm as U can undo the steps easily.
give it a try and give feedback. As i'm not sure of the download speed please let me know what's the download speed U get.

guys i finally found out how to upload images
here's speed test ( both bsnl and global speed test)

sorry guys since i have taken with my nokia cellphone camera it's not clear. here's the same picture a bit more clearer

G.Dmt is the standard mode set in all bsnl provided modem now-a-days.since mode changing depends upon how modem syncs with exchange that is why i said that at these times maybe bsnl engineers tested lines by using G.Dmt mode with no restrictions on speed & that is why your modem operational mode changes automatically with increased speeds.

i don't think they are testing as i am getting it constantly for past 2 days. may be i have to wait till anyone else confirms it. if U guys get it please reply and also tell the download speed.
for the past week only occasionally i got 4Mbps. but after diabling ADSL 2 & ADSL2+ yesterday i get it whenever i logged in. And even if i swtch off and switch on the modem the speed stays.

disabling not diabling sorry.

my operation mode is Gdmt from the beginning & almost all users having bsnl provided modems have Gdmt mode as default so i guess you are among the lucky few whose area speeds are increased.as for me i get download speeds around 1.8-1.9mbps & i would suggest you to check your download speed by actually downloading some big file & then see how much speed you get.

just suggest the link of any big file to download (it would be better if U have already downloaded it with 1.9Mbps so that we can compare speeds).
this sounds silly but actually i havn't downloaded any big files.

try this.windows XP SP3 from softpedia.took me around 26 minutes to download in afternoon using IDM---

Do you believe this ??? I am from kerala....i got this 2 test between 5 mins interval...Mine is a home 500 plan & from yesterday onwards its damn slow also.....(70-80 kbps)...I think this bsnl speed tester is a fake one ...When i was in mandriva linux it shows 10 kb/s and in win xp its 200 kb/s (same system).....but downloading speed is same (10-15 kb/s ) (yesterday).......Anyway i have to complain abt my connection's speed...earlier it was 200 kb/s.....

Why have you taken the picture with your phone ? Just press "print sreen" i.e, "prt scr" on your keyboard and paste in paint or any other image editing tool.

thanks i didn't know it. ok here's a test i took just now

@narasimhan1990,did you try to download the XP SP3 from the link i gave to see how much speed you get in free time.

I have both ubuntu linux and xp.
bsnl speed tester works only in xp( or i think U need to change some settings in linux). even for me in linux it shows below 10Kbps. but the browsing speeds are the same. i find no difference.

have you tried downloading XP SP3 from the link in one of my previous posts to see the actual download speed possible on your connection?

try this.windows XP SP3 from softpedia.took me around 26 minutes to download in afternoon using IDM---

i downloaded it today morning. it took me 24 min( not much different from yours). but the significant thing is avg spedd was 280KB/s and peak speed was 330KB/s and most of the time it was above 270KB/s. but twice it went down to 90KB/s hence it took 24min. but the thing is all speed tests show above 3Mbps.
And also webpages and you tube videos open very fast.
I presume that for a youtube video to play properly U need to wait for a minute or so for it to load( usually happens for me before). but now i plays instantly without break. for a 20min video it loads fully within 3 mins( high quality).
So i'll download more and tell U tomorrow.

if U havn't seen yet see my previous post for download speed.
what is the use of xp sp3. should i install it. i presently have xp sp2(not original).

my suggestion is install it.it should install even if xp is not original.i am using it & my system's performance is much better than before though i did a format & then install a fresh copy of XP SP2 & then immediately installed SP3.also let me know your download speeds for other downloads too preferably for big files like movies using torrents.
