My hardware is as follows:
Cable modem connected to internet
CAT 6 Ethernet cable from cable modem to First ASUS RT-AC66U Wireless 802.11AC Router
CAT 6 Ethernet cable from AUS Router to Main PC
Second ASUS RT-AC66U Wireless 802.11AC Router setup up as Wireless Bridge
CAT 6 Ethernet cable from Second Router to Home Theater PC
CAT 6 Ethernet cable from Second Router to Synology Diskstation DS +1812 networked hard disk
Here is my problem - if I log into my "Main PC" and try to transfer files wirelessly from the "Main PC" to the Synology networked hard disk, I get transfer speeds around 4 MBps, way too slow. But if I login into my "Home Theater PC" and initiate the same transfer from my "Main PC" to the "Synology", I get a 40 MBps transfer speed. Am I missing something? Is there a setting I need to change?
If there is any more info anyone needs just let me know.
802.11ac still in draft mode not standard yet so you have to overlook that, but what type of PC you have there as the Main PC.
What NIC (network interface card)?
Is the NIC on-the MOBO (motherboard)?
Is the NIC in a slot?
Does this NIC have TX and RX Buffering?
Have you changed any settings on the Main PC?
Are you just running the defaults on it?
Is the Home Theater PC and the Main PC what is the difference between the two in and OS hardware wise?
Every PC on your network should have the same type of tweaks. WiFi tweaks the defaults are okay for the NIC, but the TCP/IP for the OS should be tweak to match all PC. A lot of people don't even bother to off-load the CPU to use NPU instead to make transfers go faster.
Another issue is the main PC HDD is that IDE or SATA which SATA is that first gen or second gen? Is that spinning at 7200rpm or 5400rpm. Is the NIC PCI or PCI-E. A lot of factors to consider.
WiFi have you done a site to site survey to make sure the WiFi Signal is strong enough and has good quality to get to your clients devices. Bad signal can run into issues too.
