No, instead I waited for some time and refreshed, refreshed and finally after about 15-20 minutes I found the Inbox opening. Then I tried signed out, again failed. Then after some time Signed out worked like charm and everything is so smooth back again.

All during this period my rounter links are all glowing and showing activity.

I discussed this problem with BSNL people. These were their responses :
a) When I pursued with the docket no. several times, I was told that from the exchange till my junction box the line is OK. No problem. I was to just try rebooting few times and things will work.

Result : I did that and it worked! I had to reboot the modem few times and then I found eveything working well.

b) Still when the problem seemed to happen on a regular basis and I discussed with their technical people, I was given two DNS's and told to try them.

Result : I tried and it did worked for one day only. Next day the same problem happened and I switched back to Automatic DNS in both Vista and Ubuntu.

One more strange thing I have noted. I have found quite regularly that all the problem with web pages not opening at times are only happening from 11am or later. When I opened my PC in the morning, everyday the connection worked well.

cool_techie_tvm - I am extremely grateful to you for your great support and your effort to help me out.

Always happy to help. This thing just occurred to me. So posting it in here. I have seen ADSL modems loosing proper functionality due to overheating. I pray that u keep the modem cooled and away from EMF generating devices such as cabinet, monitor, speakers, UPS.

You can try this also
adapter input of the modem should be through UPS because in many area at some particula interval input ac is high which result in unproper function of modem
adapter max input is up 240 V if it is from 245- 260 or more up to particulat time it work but after sometime *****************

so u can also try this

it is ELECTROMOTIVE FORCE

U SAID EMF stands for electromagnetic force. SAME THING BUTT

explain it clearly

how he is connected his phone to router whether his router is having rj 11 connectivity for phone which means that his router is inbuilt splitter


and if he wants to connect phone after router then he can use

just tell exchange people to reset ur port even after resetting ur port if ur problem is no solve not getting then tell me that change ur port

it is good that ur problem is solved

Yes, this can be a reason. My D-Link Router is getting heated within say 10-15 minutes of starting operation. I purchased it quite recently (3 month approx). I will not say that it gets extreme hot, but yes when I touch the top surface it feels little hot.

It is also sitting next to my speaker and Monitor. I will reposition it now to a cooler and away from heat position. May be this helps. BTW, can you please explain "EMF", I failed to understand it.


Yes, it is through UPS only. But thanks for giving the idea. It really helps. In fact I used it from normal point (UPS) just a few days back to check whether power supply is the cause.

Now I will report back here after I change the position of the Router and observe the result.

Thanks for your great help.

EMF stands for electromagnetic force.

When a current is passed through a metal, then it produces a magnetic field about it. The same happens when a magnetic field is being cut with a metal (a current is induced in the metal in this case). Monitors, speakers and cabinet are high sources of stray EMF and this may impact the normal functioning of the router. Hence i told u to place them away from such sources.

Many thanks.

I have now moved the router in a different location. I have to observe for a sufficient time and then report here.

In the mean time it will be great to get your views on the following :
a) I am not using a separate splitter, given by BSNL. Because I am using the router and the BSNL line is directly going straight to the router. I am linking the landline also from the Router and the switch is connected to the router. Is this correct?

b) If divide the phone line (which is coming out from the router) into two different lines (by using another junction box), so that I can use parallel line, will that be correct? I think this is not OK.

c) For the heating issue, do you feel I need to change the router and try some other model/brand.

cool_techie_tvm

a) Why arent u using the splitter given along with the connection? Does the modem feature inbuilt splitter? Normally the main telephone line is kept as input to the splitter. The two outputs of splitter are fed into the modem and the telephone.

b) The telephone out of the splitter can be used to give parallel connections. All such connections should be given after the splitter only. I hope u understand this point. If not please state so

c) Since this modem is just 3 months old, i suggest u wait for some more time.

cool_techie_tvm

I thought u were a broadband subscriber for the past 2 years. Yet u find this post of mine confusing?

If aray finds it hard to digest i will explain more.

aray

I will try to explain as per the above points :

a) I was using the splitter earlier, but since this problem started to happen, I thought to try directly connecting to the router. I am not aware whether GLB-502T has an inbuilt splitter or not but when I checked the diagram of the router, I found it shows telephone line directly connecting to the Router, no splitter shown in between . So I thought let's work without the splitter. If this is not the correct way then I will go back and again work through the splitter.

b) This a great news for me . I asked here because the telephone people always advise not to use parallel line. May be I misunderstood it.

c) Ok, I will wait and see. But I found quite a few negative feedbacks about this router. May be purchasing this router was not a good decision.

Just for my knowledge I would like to know which ADSL router do you recommend for daily usage. I have two PC's (Router > Switch > PC's connected). The router will be in use for approx 14+ hours daily.

Yes, I am connecting through a RJ 11 connectivity of the router.

Back Again.

The problem is still happening even after moving the Router to a better place. When I logged in, I was able to work normally but just after sometime (may be about 25-30 min.), suddenly the PPPoE link went off, then when the link came back after a while, again sites like Google not working.

I found the router heated. Although all the four lights are showing ON but still some of the pages are not opening.

This time I took a screenshot of the Modem Status from Router, when it restarted. From my limited understanding (from this forum about SNR margin), I think it shows a much lower value than it should be (marked in the screenshot). I found that even when the Router gets started the DS margin shows a value of 7 or 8 at the highest. I checked this several times.

I checked my line also, Phone working correctly - no noise etc. I have also now added the Splitter but again this problem happened.

Is this a Router related problem? In that case I can go back to the BSNL Nokia Siemens Router (C-2110). Will it work with a Switch?

The Downstream SNR is really low. It should be atleast 6 for a sustained connection. Now i am beginning to wondering whether it is an earthing problem on telephone line..

Something is fundamentally wrong with the arrangement (on BSNL side). So switching between the routers/modems is not going to help. If the Siemens router has 2 or more Ethernet ports, it can be configured to work as a switch/hub.

aray

Thanks cool_techie_tvm.

About the earthing problem, does it in any way related to a faulty telephone set?

cool_techie_tvm

No, it is dependent upon the telephone line. Minor cracks maybe present, which may cause earthing/grounding. Get the telephone line checked thoroughly from BSNL. Mention this term earthing and they will know what is to be done.

aray

Ok, I will surely mention it when I talk to them tomorrow. I already have booked a Docket and hopefully this info (of earthing) will help to solve the issue.

Thanks cool_techi_tvm

hi aray
staying in lansdown kolkata facing this prob for the past 2-3 days
is it a area specific problemm..
what area do u stay in

aray

You are also facing the same problem? That means we probably have nothing wrong at our end.

I don't think it's area specific but may be plan specific. Are you also using the same plan (U/L 750+ which now is U/L 500+)?

When I went to the exchange last week (it is very difficult to find these people when you visit there), I found another person who also complained at the same time with me. Then they gave us the two different DNS's.

But that has not solved the problem.

cool_techie_tvm

The tariff of UL 750 has been reduced from 750/- to 500/- in calcutta circle only. They havent altered any of your settings. When u are billed instead of charging 750/- only 500/- will be charged.

Hence there is no change in the plan profile or speed profile in the existing plan.

aray

Yes, that is correct but at the same time when the monthly charges are reduced by Rs.250/- monthly, it is also expected that more additional users will join the network. That means more load on the network and that made one wonder whether the present system is capable of taking the extra load or not.

Moreover as you know that they withdrew the extra bandwidth offer also via a message at this page : Calcutta Telephones.

I think these points can be nothing but can also be a pointer to the problem also. When one faces a problem for a considerable period of time it may be viable to think all possible reasons for the problem.

When many users are getting into some kind of problem, from a certain period of time, which co-incidentally matches with the launch of a changed plan, it raises doubt whether the plan is a cause.

But at the same time I do agree that it's only a doubt and not a confirmation. These things can only be confirmed by the technical people of the service providers.

hi aray
i am using the 500 per month plan which has download free from 2 to 8

cool_techie_tvm

Hey tell the exchange people to change your port too. The port to which your line is connected with the DSLAM present in the exchange. They must be knowing it, for i have also come across certain cases in which changing and reconfiguring the port worked.
