    Router slows down after 24-48 hours (not SNR/sync related)

      Question Router slows down after 24-48 hours (not SNR/sync related)

      I've been connected to Sky for about a week now and have found that the supplied DG834GT has an issue where speeds drop dramatically after approx 24-48 hours uptime. Note this is not SNR/sync related, the drops occur outside of the usual evening time and the SNR for my connection stays high all the time, usually never lower than 13dB.

      When the router is operating normally I get download speeds of up to 7mbit/sec on various speedtests (I am on the mid package and my sync is around 8192kbps). After a day or two download speeds drop dramatically to 512kpbs or lower, and a reboot instantly resolves the issue. Note my PC is directly connected to the built-in switch, I am not using wireless clients and the wireless functionality is disabled.

      Anyone else noticed this behaviour, is faulty hardware or the crappy netgear firmware likely to be the cause? I'm inclined to try the alternative, earlier netgear firmware releases to see if the resolve the issue.

      Sky may have got a very good deal from netgear for the DG834GT, but i've a feeling it's going to cost them a lot more in support costs in the long run

      Had exactly the same problem. It was usually after 72hrs and happened at all times of the day, not just in the evening. I thought it was related to using torrents as it seemed to be happening more oftne when I was using utorrent. However I went for ten days without downloading and it still occurred.

      Tier 3 have capped my line at 12Meg and it seems to have stabilised it - been running utorrent for over three days now and haven't had any further drops.

      If you are having this problem, it is due to errors building up at the exchange.

      If enough fec, crc, errors build up, the line will slow down and eventually drop. these errors are usually caused by the DSLAM card settings being set to high for the line to handle. If you have the line capped, the broadband will stablise and the problem will go away.

      Ps, resetting the router also clears the card at the exchange and resets the counters to zero, thats why the line will go back to normal but will gradually slow down until it needs reset again.

      Three points:

      1. The high (and stable) SNR suggests the line is more than able to handle the negotiated sync speed.
      2. Prior to moving to Sky the line synced at the same speed on both BT IPStream Max and an LLU wholesale service provided by Tiscali with no problems.
      3. This issue doesn't occur if I use my other wireless router (linksys).

      So it looks to me like this is a problem with the DG834GT.

      Also why would a number of FEC, CRC errors cause the line to degrade dramitcally? That's the whole point of having interleaving - more correctable errors = fewer dropped packets and re-transmits.

      Same issue here, but more frequent (within 24 hours). One thing to note is that it has on at least one occasion done this, then fixed itself without rebooting. Using the original Netgear firmware did not solve the problem.

      My router also crashes completely approximately once a day (seemed to be more often with the Sky firmware) and my line stats are fine and it never actually drops the connection completely.

      And before anyone asks, the problem persists beyond disabling UPnP and using Auto 108Mbps.

      i have experienced the slowdown effect.

      this morning about 6:15am, downloads were about 10kbps. restarted router, instantly got back to normal ~1000kbps.

      There are 3 connection stages -

      sync

      atm - session layer

      ppp - session layer

      A few errors on the line can cause the router to loose the ppp session layer thus disconnecting your session.

      Resetting the router allows the router to reestablish the ppp session and regain your ip address from the pool.

      Your connection does not literally slow down the line speed, the errors slow the acquisition of correct packets which makes the download speed appear slower.

      But the PPP session never drops...

      Seems to have been better the past few days and not had to reboot the router for a while. Of course now i've said that it will be all over the place for the next few days
