Let's get my hardware/software setup out of the way first: OS: Windows 10 Professional 64bit Mobo: MSI-7850 Motherboard Proc: Intel Core i5-4570 RAM: 8192MB DDR3 1600MHz NIC: Intel Gigabit CT Desktop Adapter Router: Linksys EA6200 Modem: Motorola SB5120 (Provided by ISP) Speedtest Info: My most recent speedtest.net result shows my download speed at around 16Mb/s, upload speed at about 1.11Mb/s. I am on a LAN connection, not WiFi. Every time I download a large file and am using as much of my bandwidth as possible for an extended period of time, my connection drops after only a few minutes, reconnects, and resumes downloading at full speed. Lather, rinse, repeat. This is especially annoying when I am simply trying to download a game off of Steam. Grand Theft Auto V literally takes me days to download because of this irritating interruption. This problem has persisted for many months. I have updated all of my network drivers, configured all of my IPv4 settings for transmit and receive, checked through all of my router settings, tried several different routers with no change in the behavior, and connected directly to my modem. The drops appeared to cease when connected directly to the modem, but resulted in speeds between 300Kb/s and 1Mb/s download which, given my speedtest results, was completely unacceptable. The exact settings for my Intel Adapter are as follows: Adapative Inter-Frame Spacing: Disabled Flow Control: Enabled Gigabit Master Slave Mode: Auto Detect Interrupt Moderation: Enabled Interrupt Moderation Rate: Adapative IPv4 Checksum Offload: Rx & Tx Enabled Jumbo Packet: Disabled Large Send Offload V2 (IPv4): Enabled Large Send Offload V2 (IPv6): Disabled Locally Administered Address: Not Set Log Link State Event: Enabled Maximum Number of RSS Queues: 2 Queues Packet Priority & VLAN: Packet Priority & VLAN Enabled Receive Buffers: 512 Receive Side Scaling: Enabled Speed & Duplex: 100Mbps Full Duplex TCP Checksum Offload (IPv4): Enabled TCP Checksum Offload (IPv6): Disabled Transmit Buffers: 1024 UDP Checksum Offload (IPv4): Enabled UDP Checksum Offload (IPv6): Disabled Wait for Link: Auto Detect Since my connection does not use IPv6 configuration, all options for it were disabled by me. Internet Sharing options have been disabled by me. I am the only computer on this network, and the only computer attached to this router. I have Google'd this problem off and on over the past few months with no leads and no successful tweaks. I even attempted to download a 1.8GB file on a Linux-based machine and the connection drops persisted. I am, at this point, wondering if this problem is due to an upload limit problem or if it is a bad modem. If there is anyone out there that can shed some light on this issue or confirm my suspicions, I would greatly appreciate it. I am completely out of ideas on what to try next.
