Set network for filesharing and different network (wifi) for internet

Hello folks!
I am having trouble in setting up my home network vs. my internet connection via WiFi.
I have two PCs which I connected directly with a twisted pair LAN cable. Both PCs are also connected to my modem/wifi router via wifi antennas. My appartment is not suitable for cable connection to the router, so the wifi antennas are the only option to get internet access.
Now, when both PCs are connected to the wireless network the connection between them is always handeled via the wireless network which runs effectively at around 100Mbps. That is of course much slower than the 1Gbit LAN connection via the cable.
But here is my problem, as long as both PCs are connected via Wifi, they never use file sharing via the LAN connection where I could benefit of 100MB/s instead of 12MB/s transfer speed.
The only solution is to turn off wifi but then I lose internet access on that PC.

I hope someone can help me and tell me how to tell Windows, that I want to have filesharing ONLY via the LAN network and internet via WiFi.

Thanks
Peter

You might consider a second router near your PC's configured in bridge mode. You can then connect both PC's to the second router via Ethernet and have both fast file sharing and internet access.

To be clear you have both pcs connected to each other correct? what is the ip range for that? you then connect to the net on both via wireless what is the router and wifi cards as n type can do 300 meg and AC can do 3 gig

Way back when, Windows XP had a checkbox to "Allow other network users to connect through this computer’s Internet connection."

If this feature is still available in Windows 10, you could disable the wireless NIC on PC No.2 and enable "Allow other network users to connect through this computer’s Internet connection" on PC No.1. As I recall, this method required an Ethernet Crossover cable between PC No. 1 and PC No. 2.

I also believe that this method permitted file and print sharing between PC No. 1 and PC No. 2 with the transfer speed set by the slowest Ethernet NIC.

Thanks, but that is exactly what I wanted to prevent. Why spend extra money?

Yes, that also crossed my mind and this method is available somewhere in the settings in Win10. So I gave it a try but it did not work either.

I totally agree but there are ways to be creative with a wireless router.

HTH,

Thanks I will try that.

Hi there

This usually works a treat. I run 5 computers this way - 2 of which don't have Wifi anyway !!!

1) Small cheap unmanaged switch .
2) USB-->LAN adapter (for computers that don't have LAN connector but only built in wifi NIC).
3) LAN cable from computer to switch
4) LAN Cable from switch to a decent dual band fast wifi extender with ethernet port(s)
5) WIFI connection wifi extender to router.

Note if you set the wifi extender to use BOTH 5Ghz AND 2.4 Ghz concurrently and the USB->LAN adapter to work in FULL DUPLEX mode you get the full benefit of maximum throughput. The newer wifi extenders can easily theoretically do almost 1 Gb/s (GigaBIT to avoid confusion) these days .

The reason for using the switch is - you can connect more devices and the transfer is much faster than simply having a Lan cable direct from the USB adapter into the wifi extender alone. I can't give you reasons for this but on using say ookla speed test I see that it's much faster with the switch than without so maybe something in the switch optimises the data transfer.

Also use things like filezilla (Free) for file transfer over the network -- much faster than file explorer / samba / RDP and of course you can use things like sftp and encryption for data transmission --good especially over the internet.

(If you want a REMOTE computer to access your Windows machine via sftp then ensure that the openssh server is installed (via optional apps) and openssh service starts at boot).

Thanks but I considered all of that. My apartment limits the usage of any Wireless solution, due to the fact it is in an old building (from 1904) with very thick walls. The internet access is in the hall, while my PCs are in two seperate rooms to which I have no way how to get any cable connection (without installing approx 20m of cables somehow through the thick walls etc.). All of the tips you mentioned mean investments I don´t see why to make, when my two PCs are connected and everything is working - apart from the transfer speed, as mentioned in my original post.

Hi there
If you can use a wifi extender (the decent ones are very good) above solution can allow really fast transfer speeds --modern decent extenders have much better wireless chips in them these days -- unless your walls are of Nuclear bombproof concrete you should be able to make the new ones work.

Up to 1 Gib/s



Of course if you want a cheaper solution then OK this isn't ideal --there might be some people for whom this method works fine --especially if you have equipment without wifi and can't run a load of cables -- the wifi extender can be anywhere -- even 1 metre away from the computer in the same room. The idea is to get LAN cable type speeds over wifi.
