Strange Internet Problem

[dododo123]

My internet has been having this really strange issue for the last two days. What happens is that it'll work for about 2-4 minutes, and then suddenly die completely. I can fix this by going into my routers setup (huawei 510) and rebooting it from there, subsequent to which my internet starts working again. Unfortunately, it'll only work for less than 5 minutes, after which I have to do another reboot.

Some info:

1) I have a PTCL connection which has been running perfectly fine with almost no issues for 6+ months
2) My line quality (attenuation/SNR) are within recommended parameters
3) My ethernet cable and computer are fine, since I tested the internet with a different computer and ethernet cable, and had the exact same issue
4) When the internet does work after a router reboot, it is PERFECT, ie normal ping and download/upload values.

Now, only three things come to my mind:

1) My router is dying/dead and needs replacement
2) My ISP (PTCL) is having issues right now, and when they sort them out, my internet will get ok
3) My line got damaged (eg due to the recent rains), but its SNR is fluctuating a lot, and its possible that it fluctuates to really low levels for a short amount of time, which is enough so that my internet dies, but doesnt last so long that I can readily pick it up in the routers set up

Of the above, 2 doesnt really make sense, because if PTCL was having issues, a simple router reboot should not be able to fix my internet.

1 and 3 seem plausible. I've had the rain damage my lines once before, but when that happened my internet just got really slow with higher pings and a few disconnects. In other words, it worked continuously, but just had a low overall quality. The current issue is that it keeps dying completely, but after a router reboot, it works PERFECTLY for a few minutes. ie the ping is normal and so is the speed (download and upload).

Any help is appreciated.


PS: I have an unrelated question: What is the sync rate (line rate upstream and downstream) that the router shows? My sync rate is 4000kbps (4 mbps) downstream, 800kbps upstream. Is this the theoretical maximum speed my line can support? I'm aware a little data is lost as "overhead", but do these values mean that my line with its present attenuation and SNR can support about 3.5mbps maximum (should such speeds become available)? An explanation on this will be much appreciated.

Thanks in advance.

dude u do no tht ptcl employees r on a strike n as a matter of fact its there in the news ppr under the headin "PTCL DSL customers suffer!" so im bettin nothins wrong frm ur end so hang in there fr a week till ths strke wears out n hopefully ull be back to normal

Actually this is sounds like a issue with your phone line connection or may be of your modem. PTCL DSL service is facing the over-load problem these days, but still I never faced this 4-5 DCing problem from other users.

barrow your friend modem and try that one and check your phone like for any kind of distortion.

actually i agree wt inferno!!!! u shld borrow sm1s modem n check it out to b sure

believe it or not my modem disconnects 20 - 40 times a day lol SuCKAGE!!

All right thanks guys. I guess I'll check my end first, ie the router + my line, and fix any problem should I find one. If everythings ok at my end, I guess I'll just have to wait the strike out.

Sucks

Yar iam having the same problem but it occurs after 1 hour. Try for manually configuring ips and dns servers.

dude im guessin k changin da dns would render da connection useless cuz dns is da address of da server tht u connect to n if u enter da address wrng it wont connect till u put in da right dns though u can change ur ip cuz thts the connection wt da modem!!!! dun mean to contradict afnansj but i do think othrwise
