Setting up wifi router as a switch for Internet Connection Sharing


Can my laptop with a 3G connection share its Internet via a Wifi router (Dlink DIR-615)?


If so, what should I set on my laptop, on my router or on the devices connecting to the router?



Answer



How to configure a Wi-Fi router to share your computer's 3G data stick connection to everyone.



  1. Connect to the Internet on your 3G data stick.

  2. Plug your laptop to one of the router's LAN ports. Wait until the router connects correctly.

  3. Click Start > Control Panel > View Network status and tasks > Change adapter settings

  4. Right click the modem (or the connection where you get Internet from) > Status > Details. Write down the "IPv4 DNS Servers" on a piece of paper. Click Close once.

  5. Right click the Local Area Network > Status > Details. Write down the "IPv4 Default Gateway". Click Close > Close.

  6. Open the browser and type the IPv4 Default Gateway on the addressbar. Routers are all different so you need to figure out where to find and configure the following:

    • Review your wireless security settings. What is your SSID? What is your security key? Write this down.

    • Under WAN, choose "Static IP" instead of "PPPoE" or "Automatic - DHCP".

    • Under WAN, set the WAN IP to 192.168.137.2

    • Under WAN, set the Netmask to 255.255.255.0

    • Under WAN, set the Gateway to 192.168.137.1

    • Under WAN, set the DNS Server(s) to the "IPv4 DNS Servers" you got from step 4.

    • Click Save.



  7. Unplug your laptop from the router's LAN port and plug it to the WAN port. Wait until the router connects correctly.

  8. Go back to the "Network connection" screen on Step 4 > Properties > Sharing >

    • Check "Allow other network users to connect through this computer's Internet connection."

    • Under Home networking connection choose "Local Area Connection"

    • Click OK then OK.



  9. Right click the Local Area Network > Status > Details. Is the IPv4 address "192.168.137.1"? If yes, then you're done! Tell everyone to connect to the wireless router and they will be online.



NOTE: There's a router-less method using "ad-hoc networks", but using a router provides more range and can handle more connected computers or wifi phones.




To put things back to before.



  1. Uncheck the "Allow other network users to connect through this computer's Internet connection." on Step 7. Click OK.

  2. Unplug the laptop from the router's WAN port and plug it into one of its LAN ports.

  3. Open a browser and visit the "IPv4 Default Gateway" address you got from Step 5.

  4. Switch the WAN setting from "Fixed IP" back to "Automatic - DHCP". Save changes.

  5. You're done!



Only one more thing: Sometimes, after the configuration, it is necessary to restart your modem, computer and router. In one situation, I connected them in this way. Modem → My Computer → Router → all other devices (like laptop, network printer, other computer).

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

ubuntu - Why does my USB hdd returns SG_IO: bad/missing sense data?

I am able to boot and run commands from external USB hdd; the message in question appears for about 45 seconds then booting continues. GRUB2 is installed on internal HDD. When choosing to boot directly to /dev/sdb the message doesn't appear, however boot time is about the same as booting to internal HDD. /dev/sdb: Timing cached reads: 1018 MB in 2.00 seconds = 508.97 MB/sec Timing buffered disk reads: 80 MB in 3.03 seconds = 26.37 MB/sec pfeiffep@de:~$ sudo hdparm -i /dev/sdb /dev/sdb: SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 10 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 HDIO_GET_IDENTITY failed: Invalid argument Gparted correctly identifies the drive as SAMSUNG MP0402H. Any ideas how to remedy the HDIO & SG_IO messages?

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
