Problem - Router Give My PC 169.254.xxx.xxx IP

  • 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

Problem - Router can't be accessed using default password

  • 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)

Can't Map a Network Drive

  • 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.

1Gb Ethernet Direct Connection

  • crossover wiring type ethernet cable is a part of history already, nowadays all ethernet adapter ports support Auto-MDIX (automatic medium-dependent interface crossover)
  • 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.
  • The Direct Connection Ethernet adapter setup
    • on that direct Network Connection property, setup IP4 connection IP manually,
      • 1.1.1.1 on one computer with mask 255.255.255.252
      • 1.1.1.2 on other computer with mask 255.255.255.252
      • and map network drive with that direct ip address like, access \\1.1.1.1\myShareFolderName on 1.1.1.2 computer
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

10Gb Direct Connection Setup

  • 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
  • However, currently brand new setup can be as expensive as computer itself for 10Gb connection
  • Cheap option
    • sfp+ copper cable and sfp+ network adapter (normally around 60SGD in 2nd hand, cable around 3 meter most time)
    • old generation of intel X540-T1,T2 10Gb Ethernet adapter (90sgd in 2nd hand) and standard cat6 Ethernet cable (6sgd for 5meter new)
    • new generation of intel X550 10Gb Ethernet adapter (???sgd in 2nd hand) and standard cat6 Ethernet cable
    • brand new Asus XG-C100C 10Gb Ethernet adaper (99USD new)
  • Chinese Name: 万兆以太网
