Hi, you're facing a challenge with transferring large backup files from a BitLocker SSD to a Windows Server 2012 machine. The network speed is quite slow, and you're experiencing issues even after testing multiple setups. Here are some steps you can try to troubleshoot:
1. **Check Network Configuration**
- Ensure both the PC and server are connected via a Gigabit Ethernet switch or router.
- Verify that the network settings on both devices are correctly configured for Gigabit mode.
2. **Test with Different Cables**
- Try using a different cable type (e.g., Cat6 vs. Cat5) to rule out physical layer issues.
3. **Use a Different Port or Switch**
- If possible, connect the PC and server to a different switch or port to see if the speed improves.
4. **Check for Firmware Updates**
- Ensure both devices have the latest firmware and drivers installed.
5. **Inspect Firewall and Security Software**
- Temporarily disable firewalls or antivirus to see if they're blocking the transfer.
6. **Monitor Disk Usage and Queues**
- Use tools like `diskutil` or `iostat` to check if the drive is being accessed properly.
7. **Consider Using a Different Server**
- If the issue persists, try transferring files to another server or cloud storage for testing.
8. **Review BitLocker Configuration**
- Ensure the BitLocker settings allow remote access and proper encryption keys are configured.
If you're still having trouble, consider reaching out to your IT support team for deeper diagnostics or checking if the network infrastructure needs optimization.
No, the question is about whether devices share the same subnet.
They are what I understand to be the basic setup. It's not a complicated setup: ISP-provided modem/router (100Mbps) – we've faced some problems with my ASUS VDSL modem, though it was Gigabit – then a gigabit switch, followed by a server with a static IP (gigabit), then a backup LTE modem, office NUC (gigabit), and finally PCs that run at 100 Mbps (printer, card terminal). I really doubt the router can handle multiple subnets. The server appears on a network drive for all other PCs, and I thought a single subnet would suffice. Later this week I can try disconnecting the router or connecting the server and NUC directly, but that seems unnecessary. I also ran Device Manager on all PCs to verify Automatic Negotiation is enabled for all network cards, which it is.
That's a straightforward topology overall. To confirm the switch isn't the problem, you could link the NUC and PC in a loop and run tests with iperf or file transfers. The devices should negotiate gigabit speeds, but something might be off. You might also run iperf on the server and a few clients to verify. If large file transfers hit a 100Mbps limit, it could indicate an issue. Do you have the switch model on hand? It’s possible the device is outdated and handling switching through its CPU instead of hardware. As a note, you can place the PC in a different subnet to test connectivity with the server—this is how I set up some machines. If it works outside the router, the problem likely lies with the ISP modem or router’s VLAN support.
It seems the setup likely involved some issues with the BTS connection, as the transfer speed matched what I needed. My laptop handled it smoothly at 1Gbit, while the other PC struggled at 100Mbit. I checked with my own device and confirmed the performance. The router appears to be malfunctioning, having reset itself multiple times recently. I prioritized getting the internet up and decided to switch to an ASUS DSL-AC55U.
