My home network runs on TOTOLINK A2004NS (Firmware V1.0.0) WiFi router which is capable of Gigabit wifi speeds. 100 Mbps internet comes from fibre optic modem through a cat5 cable [100 Mbps] to the router. Nodes include a MacBook Air early 2015; 2 windows 10 laptops - both with Gigabit Wireless; a Raspberry Pi4 with OMV 5 in it [connected through WiFi]; an iPhone SE, mi4i phone, Amazon Fire stick, Amazon Echodot and an HP wireless printer. Except the printer and mi4i phone, rest all devices are capable of connecting to 5 Ghz Wifi. The transfer speed of the RPi4 OMV NAS setup maxes out at 12 MByte/s. Basis my research in forums & google, tried the below tests to see if the transfer speed increases - all tests resulted in a max of 12 MByte/s. Used Wifi in RPi4 as I don't have a Cat5e/Cat6 cable handy - unable to get one due to the lockdown
1. Removed the cat5 cable from router and ran the LAN network w/o internet - results are the same
2. Turned off 2.4 Ghz band of the router - results are the same [in this setup, the printer and mi phone are not able to connect to LAN - rest of the devices functions as usual]
3. Shared a folder on the windows laptop and copied files to Mac and tried visa versa [OMV and RPi4 are not in the equation of this setup] - still the transfer speed caps at 12 Mbyte/s
4. Made one of the Win 10 laptop a hotspot and connected Macbook to its Wifi and tested transfer speed between the Laptops - still the transfer speed caps at 12 MBytes/sec [Router is out of the equation here]
LAN connection speed on windows Laptop reads 433 Mbps range [Fluctuates] and Macbook reads 300 Mbps range [fluctuates]
I'm not able to figure out what is stopping the network from operating at a better speed, if not Gigabit speeds. I know this is not related to OMV as the above tests rules that out - but desperately looking for help - Also not sure if the above tests makes any sense.
