+ | * note, the onedrive/ | ||
+ | * step: | ||
+ | * login in onedrive https:// | ||
+ | * then, in your computer, map network drive, and put address as https:// | ||
+ | * then, when pop up the login, just type in login as like in browser | ||
+ | |||
+ | ====== 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 " | ||
+ | * 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; | ||
+ | - Open Control Panel > Network and Internet > Network Connections to see the actual Ethernet port/WIFI connection that you are using | ||
+ | - Right click on the your current network connection icon, choose property > check " | ||
+ | - Instead of letting IPv4 auto get your IP, you use manual entered IP address: 192.168.1.x (e.g. 192.168.1.5), | ||
+ | - 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 < | ||
+ | * additional note: make sure setting the folder permission with "full control" | ||
+ | |||
+ | ====== 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) | ||
+ | * which means: the port interface automatically detects the required cable connection type (straight through or crossover) and configures the connection appropriately | ||
+ | * wiki ref: https:// | ||
+ | |||
+ | * 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 (**Note**: if win10 interface hard to set ip, then just commandline admin mode faster) | ||
+ | * on that direct Network Connection property, setup IP4 connection IP manually, | ||
+ | * 1.1.1.1 on one computer with mask 255.255.255.0 < | ||
+ | * 1.1.1.2 on other computer with mask 255.255.255.0 < | ||
+ | * 1.1.1.3 on other computer with mask 255.255.255.0 < | ||
+ | * and map network drive with that direct ip address like, access \\1.1.1.1\myShareFolderName on 1.1.1.2 computer | ||
+ | * For win10 auto change ip setting after restart, you need to go Windows 10 setting > Network > that Adapter: IP settings set | ||
+ | * ip assignment: manual, ipv4: 1.1.1.1; subnet length: 24; gateway: 1.1.1.0 | ||
+ | * if auto configure still kick back, go regedit admin right: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}, | ||
+ | * then, add a DWORD " | ||

+ | ====== 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 | ||
+ | |||
+ | * 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) | ||
