- note, the onedrive/outlook acc should not have 2-step authenication
step:
- login in onedrive https://onedrive.live.com to check your “cid” number in your url
- then, in your computer, map network drive, and put address as https://d.docs.live.net/YOUR_CID_NUMER
- then, when pop up the login, just type in login as like in browser

Normally, in a local network setup like Home WiFi network, it gives every device a local IP address, like 192.168.1.xxx;
Problem: If your PC are in 169.254.xxx.xxx situation (check with “ipconfig” command in cmd app) during network setup, you can't access your router at its default 192.168.1.1 address in internet browser
Solution: in order to access 192.168.1.1 address, you may need to manually set your PC IP to like 192.168.1.xxx; here is the steps:
1. Open Control Panel > Network and Internet > Network Connections to see the actual Ethernet port/WIFI connection that you are using
2. Right click on the your current network connection icon, choose property > check “internet Protocol Version 4 (TCP/IPv4) Property
3. Instead of letting IPv4 auto get your IP, you use manual entered IP address: 192.168.1.x (e.g. 192.168.1.5), subnet mask: 255.255.255.0; empty default gateway
4. now you should be able to access your Router by either Ethernet or WIFI at 192.168.1.1

press and hold reset button at router back for 5+ seconds to reset router, use Wifi or Ethernet to access 192.168.1.1 page in internet browser. (search internet for default password for your router model)

make sure the computer which is sharing the folder has a username with password,
then, in other computer, map that network driver with "\\PC_Name\path_to_the_fodler", with credential as “PC_Name\user_name” and “Password”
additional note: make sure setting the folder permission with “full control” or “change” if you want end user create or modify on that folder, as default one is read only.

crossover wiring type ethernet cable is a part of history already, nowadays all ethernet adapter ports support Auto-MDIX (automatic medium-dependent interface crossover)
- which means: the port interface automatically detects the required cable connection type (straight through or crossover) and configures the connection appropriately
- wiki ref: https://en.wikipedia.org/wiki/Medium-dependent_interface

Thus, you just need a cat6 cable or better, (cat5 is part of history as well and not available commonly) to connect 2 computer ethernet port directly.

1Gigabit speed	125MegaByte/s
real small files	61MB/s in direct connection
large 20GB file	128MB/s in direct connection
through a cheap wifi router Ethernet port	12MB/s

10GbE speed = 1250MB/s, and setup is similar as 1GbE setup, but the hardware needs to meet the spec to achieve it.
First, computer needs to have a 10Gb port.
- there are same Ethernet cable based ports network adapters and cable
- there are also copper wire cable based ports and cable (sfp+) (which is older than those new Ethernet port option)
- there are also other solution, which require driver setup properly and configured properly

Hub, Switch, & Router: https://www.youtube.com/watch?v=1z0ULvg_pW8
- Hub sends signal to all ports
- Switch send signal from one to another ports
- Router connects between networks (inter-network), while hub and switch create a network

Ports

port numbers are often associated with certain protocol, application, type of usage
- like port 80 for http, 20,21 for ftp, 443 for https
port number are in range of 0-65535
