how to improve an unstable connection

need help with my connection. The connection is unstable and SNR drops quickly that i reboot the router 2 times a day. Ping in most times is <100 but from 4 to 11 pm it becomes >100 and the down speed becomes 0.2-0.8 Mbps. So can somebody suggest what is the problem and how to solve it. I'm currently on a 2 MB ADSL subscription

Could you post your router stats? See http://kitz.co.uk/adsl/frogstats.php

It would be useful if you can also get your stats when plugged in to the test socket within modern BT master sockets. See http://www.dslzoneuk.net/socket.php?type=html

well i don't think i have a modern BT master socket. I think it's an old master socket that has many wires coming out of it.

Could you post your upstream/downstream sync rates, attenuations, and SNR margins?

Downstream / Upstream

Data rate (Kbps) 2496 / 512

Noise margin (dB) 11.1 / 17.0

Output power (dBm) 18.1 / 12.3

Attenuation (dB) 63.0 / 31.5

Hello Auser93,

Can you clarify what you mean by unstable?

Unstable connection to me usually means the broadband connection keeps disconnecting on it's own. How I've read your post, sounds like you have congestion, and your physically disconnecting it 2 times a day.

well your right i have a congestion. I have this congestion everyday from 4 to 11 pm and it's cause is many people using the internet in the same time. I asked the ISP to upgrade the equipment in the telephone exchange, but unfortunately there was no response; so is there any other way to solve this problem.

I just made a ping test at the moment and this is the result.

Very unlikely that you will be able to resolve it until the network infrastructure is sorted. Exchange, the national network, international links and more.

My results to the same server:

Speed

Ping

And that uses very little of the local infrastructure and demonstrates how the complete netwrok needs improvement.

Hello Auser93,

I was just abouts to suggest to check the congestion status of your exchange using the exchange checker, but I've just spotted your ping test results are to cairo which makes me think your in egypt. So the exchange checker that i was going to suggest only covers the UK.

The actual 4-11pm congestion may not be at your telephone exchange, but maybe at the ISP's side. ISP's are like roads, the most popular/main roads will have a lot of traffic. So if you find a small/unpopular isp, then you may be able to avoid the congestion.

Data rate (Kbps) 2496 / 512
Noise margin (dB) 11.1 / 17.0
Output power (dBm) 18.1 / 12.3
Attenuation (dB) 63.0 / 31.5

The line line is long but performing well for ADSL, assuming the noise margin is still good and same data rate, then congestion is the most likely thing. Alas providers around the world provide ADSL/consumer broadband by renting capacity that is shared between many customers, so congestion is common.

The usual pattern is this
1. New product
2. Great service
3. Lots of signups
4. Congested for a period of months
5. Some people leave
6. Eventually a backhaul network gets upgraded.

It is less about new hardware at the local exchange usually, but a case of convincing accountants to allow the extra traffic, which depending on how the local system works, may cost more money, and if prices are static and number of subscribers not changing this means (6) can take a long time.
