Have you come across a restriction around 50 to 59 minutes for downloads at a 6.5 Mbps connection?
Have you come across a restriction around 50 to 59 minutes for downloads at a 6.5 Mbps connection?
I've adjusted the timing for early morning in the eastern U.S. Last year I could download for hours, but now it only lasts about an hour before stopping. I had to rename files, restart them, and watch closely so the download would resume where it left off. A five-hour download would mean checking every hour and needing six to seven attempts to finish. Without a way to restart after a failure, I wouldn't have been able to complete the video. Hope this isn't a recurring issue now. Thanks!
I'm looking to obtain a specific file. Could you clarify the target content and its size? Also, please share the estimated download rate so I can gauge progress.
I share the same internet provider and ISP with comparable maximum speeds. I haven’t experienced downloading a file as large as 50 GB from my browser, though I haven’t faced your problem with lengthy Steam downloads that took hours. It seems I didn’t start a multi-hour download until after a new shield or protection device was installed on the DSL box outside. I’m unsure if you have a similar situation. Recently I discovered that mismatched MTU sizes between your network and ISP can lead to connectivity problems. The standard is around 1400, but some providers like my T-Mobile 5G use a lower value. You can run ping tests to verify the maximum packet size, then calculate accordingly. Here’s a guide with precise calculations for MTU: https://forum.peplink.com/t/how-to-deter...size/7895/ My ATT DSL setup came out at 1400, but it’s possible your area differs. I suspect router adjustments wouldn’t cause consistent drops unless the PC is losing connection or changing IP every hour. Without deep packet expertise, the only option besides capturing packets with Wireshark is to test and see what happens. ATT now provides 5G home internet in more locations, including mine—worth considering if low latency matters for you.
This appears to be the most probable option. It usually doesn’t create major issues, but if the router isn’t updating the IP quickly enough it might temporarily block the client, possibly interrupting a browser download. It’s never been wise to rely on the browser for large file transfers, which is why tools like JDownloader2 are useful.
On ADSL links with PPPoE, the maximum MTU is 1492. Ethernet frames should use 1500 bytes, minus 8 bytes for PPPoE headers. AT&T U-Verse on "IP-DSLAM" can support a full 1500 byte MTU. If the network uses PPPoA (Point-to-Point over ATM), it may also accommodate 1500 bytes because ATM typically operates with a slightly larger MTU. As MTU values drop, it often indicates the ISP uses cellular technology, where 1420 is usually the upper limit for 4G/5G due to network overhead. Be cautious—lower MTUs can signal degraded wiring or outdated infrastructure in many US areas. If your connection drops during long downloads, try accessing the modem directly and reviewing logs to check for retransmission issues.
Thanks for sharing your experience! It seems like your issue lasted about 2-3 days. (HOPE) Recently, I've been able to download 2 hours and 4 hours at a time for 5 and 10 GB files without problems. However, every time I go over 10 hours, the download gets interrupted either around noon/lunch or after 5 PM due to crowding. I plan to check the technical side of my connection to see what's causing it. I understand ISPs are pushing away landlines—hopefully they'll be required to switch to fiber if this happens! Thanks.
