[SOLVED] Share Ethernet Internet with Wifi AdHoc Network

After several hours of searching other similar threads, I cannot find anything which turns out to be useful for what I'm trying to do specifically.
I have a laptop with ethernet card and built-in wifi. With Arch Linux I have configured both before using both the ipconfig/iwconfig methods and using Wicd. I am currently connected to the internet using Wicd and Ethernet (only because Wicd is already installed and configured when I got this internet connection). It would violate the terms of my internet service here (in a dorm room through dorm sponsored internet) to connect a wireless router to the internet connection.
What I want to do then, is set up my laptop so that it accesses the internet through the ethernet connection, and shares it with my iPod Touch through an Adhoc configured on the wifi card. I believe this still may be a small violation of the terms of service with my provider, but I really just want to be able to update/download apps on my iPod.. not let the whole floor have internet for the low price of one room.
Thanks in advance for any help, let me know if I need to provide more specifics for what I'm trying to do.

you can use iwconfig to set up the ad hoc connection (i dont know enough about wicd to see if it'll work with it)
iwconfig wlan0 up
iwconfig wlan0 192.168.100.1 netmask 255.255.255.0
iwconfig mode ad-hoc
iwconfig wlan0 channel auto
iwconfig wlan0 essid MYPC
you can then use your ipod to connect to this ad hoc network and assign the ipod an ip address 192.168.100.2, make sure to ping the ipod to see if its connected corrently or not.
you can then use iptables to NAT the connections, iptables -t nat -A POSTROUTING -s 192.168.100.0/24 -o eth0 -j MASQUERADE
make sure ip forwarding is enabled by using, echo 1 > /proc/sys/net/ipv4/ip_forward

If you are asking about the Internet Sharing feature on the Mac, the answer would be that this option is not available for normal wireless, but it might work for BlueTooth. Might be worth a try that way.
However, if the Mac had an Ethernet Internet connection, then you could create your own "private" wireless network to allow wireless devices to connect.

No internet with WiFi

Cannot connect to the internet with WiFi other than my own. With all other networks, I connect to WiFi, but not the modem. Getting a message that "WiFi has the self assigned IP address 169.254.3.132 and will not be able to connect to the internet." Using a 13" MBA, 2011, 1.8 i7, Mavericks 10.9.3. This is a recent problem, have used this machine for years with no issue. Help.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Macbook air 2011 so slow speed to visit Internet with WIFI

I bought Mac book air 2011 13' inch core i5 last week. Recently, I found it is sooooo slow to visit
internet with WIFI, even I cannot open the any website with Safari..........
Is there anyone the same to me?????

Hi,
i solved the problem this way,
first reset PRAM (google for "reset PRAM lion" if you don't know how = restart and immediately push these buttons simultanously [option] [cmd] [P] [R] )
then
in network prefs, uncheck "ask for confirmation when connecting to other networks"
(or something of that kind, i don't use the english version)
this solved my problem
hope it will help you as well
give peace a chance

How do i use my iMac and the macs wired internet connection to share the internet with my iPod and iPhone

How do i use my iMac and the macs wired internet connection to share the internet with my iPod and iPhone. For 6months I had set up a network that shared the internet through bluetooth to my iPod 5th gen but i messed it up when i tried to add my iPhone 5s and i can't remember how to do it.

[SOLVED] Share Multiple Directories With Samba On Arch Linux and XP

Hello,
I have had the worst luck so far with Samba, which is far more likely because of an error on my part than on Samba's.
I can only seem to share one directory regardless of how I setup my smb.conf. And worse yet, if I mess with Samba, smb.conf, after the first time I set it up it doesn't work again until I reinstall my OS. Now I'm sure that reinstalling isn't the only option, but I haven't figured out how to make it work again any other way. I've tried uninstalling it, deleting it from the cache, deleting /etc/samba and so on, still can't connect to it from XP when I reinstall it.
I'm running Arch64 and I want to share some directories with a laptop running Windows XP.
I want to share my home folder, but have it accessible from XP only by me, share my mother's home folder, and have it accessible on XP only by her (well actually I guess it needs to be accessible by both, since i'm the admin), share my media-server (a collection of five hard drives where I store movies and such), and have it read/write by both of us. And finally share /srv so I can work on that from the XP computer as well. I think that's all. And I would like to share printers between the two computers. I would also like to access XP files from here.
I've always been able to get the media-server to share, but that's it, nothing else. And it doesn't always work right. It doesn't seem to want to follow sym links, but like I say if I mess with it it will stop working all together. So I'm not sure what to do.
A thought was to instead make a /media/samba-share directory and share that, and inside it have symlinks to my home, media-server, etc. However, that will only work if samba will follow symlinks for me.
Here is the smb.conf I am planning to use at the moment:
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
# http://www.samba.org/samba/docs/Samba-Guide.pdf
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.

Otherwise I would delete [homes], [media-server], [theavataroftime], [christina], and [server] and replace them with just [samba-share] with all those as symlinks inside that directory as before mentioned.
Anyway, thanks for the help. Any good guide on this matter would be appreciated, I have looked at several, but more can't hurt . Networking isn't my thing so to speak, so please be specific in any explanations. Thanks again.

Well it seems that my trouble all started when I began using the 'printable = yes' option for shares. Since I removed that the troubles seem to have left me.
Does anyone know why that is listed as on option in smb.conf here:
# A publicly accessible directory, but read only, except for people in
# the "staff" group
;[public]
; comment = Public Stuff
; path = /home/samba
; public = yes
; writable = yes
; printable = no
; write list = @staff
As well as in a few other examples if it doesn't work? I seen the example and assumed that option was needed to print from those shared directories.
Also, it seems that the comma is not needed between the 'valid users' names.
Also, I guess it wasn't Windows XP's fault either but rather my own ignorance. I like the idea of blaming Windows better though.....
I hope this servers to help others to aviod my mistakes.

Can I share my internet with my Ipad and simultaneously connect to a airport express that I use to remotely connect speakers?

Can I share my internet from my Imac with my Ipad and simultaneously connect to a airport express that I use to remotely to connect speakers?
The big problem that I'm having is that when internet sharing via the airport I can not simultaneously connect with my airport express. It would be great to be able to share internet from my Imac so I can be using my Ipad and at the sametime have my wife use the airport express to stream music in a different room. It would be awesome to be able to have the ability to do both. Does anybody know how?

How to share ethernet printer via wifi?

I currently have an ethernet laser printer connected to our two desktops via an ethernet router/hub. If I disconnect the ethernet hard wire from one desktop, is there a way for it to continue to access the printer (ethernet capable, not USB) if I add an Airport Extreme base station? If so, will it be able to access the printer directly as it does now, or would I have to have it use sharing with the other desktop to which the printer will still be connected via an ethernet cable? (My current wifi is supplied by a Qwest modem/router with wifi). Thank you.

If you get an AirPort Extreme, all of your wired and wireless devices will belong to the same network. Specifically, if you connect one desktop and the printer to the AirPort ethernet and connect the other desktop wirelessly, both Macs will be able to print in exactly the same way.

I can't connect to Internet with WIFI

Hi !
First, sorry for my so bad english but I'm French ;-)
I'm so desperate !
I have a Blackberry Curve 8520. I bought it on july. It worked very well, but since 3 months ago, i can't connect the BB to internet (with Wi-Fi or WAP).
I tryed many Wi-Fi, i tryed all the options and now i'm so desperate... Nothing works for me.
Can someone help me please?
Solved!
Go to Solution.

You can try this im also using Curve 9300 3G version 6 o.s
1.Turn Off / Uncheck your Mobile Network
2. Enable Wi-fi if theres a WEP just put in it.
3. Data Service should be ON - can be found on Mobile Network Options
4. Browse - Browser, Social apps etc
Hope helps
I guess if it is in WI-FI mode we can't call / receive Calls or Text on your network, seems strange in BB.

How can I share my Internet with my other devices

I have been assigned a temporary home for the next few months. The only Internet available is via a USB Dongle. The family uses iPads for their daily pleasure. Is there a way to create a shared network from my Mac Book Pro running Mountain Lion OS?

How to share proxy internet through wifi?

Hello everyone,
I am new to this community.
This is my first question I am posting here.
I am using internet in college using thunderbolt ethernet.
It is a proxy connection network.
proxy address: 172.13.10.101:3128
When I do internet sharing from thunderbolt ethernet to wifi, sometimes it is not turning into hotspot but sometimes it turns into hotspot.
But I can't able to access internet in my mobile device(samsung galaxy young duos) even though it is connected with the hotspot.
Do i need to use any third party softwares incase if it is not possible?
Please help me out on solving this issue.

There are various tunneling schemes in use, and two of the most common are PPTP and L2TP.
Your particular corporate firewall probably has one or both.
Microsoft Windows has VPN capabilities, either as an integrated or as add-on capability. Different organizations can prefer different solutions here, too. Check with [Microsoft|http://www.microsoft.com] for details and options for that operating system platform (I just don't follow Microsoft Windows security tools anymore) and with your IT staff.
Mac OS X client contains VPN client capabilities. For both PPTP and L2TP.
As for which you need or want here, that's as much a question of the capabilities of the firewall here and with which of these works best with the Windows XP box; with what actually works in this case. It is common for a corporate network to have an external firewall, and an IT staff can have specific preferences here. And some firewalls can have odd setups or incompatibilities. Check with whomever is providing your IT support, as a start.
If you are providing IT support here, you're going to have to provide details of the corporate network set-up here including the model identification of the firewall device. And please also do some research on Microsoft Windows XP for this question and on VPNs in general and on your specific corporate firewall, as a start; you own some sensitive data, and poking holes through a firewall is a bad idea. And a server security breach (and I've cleaned up a few of these) is a hassle. You need to know how this stuff works here, or you need to get some escalation help available to you; [here is a summary of various network pieces|http://labs.hoffmanlabs.com/node/275] that can be involved in your network.

Problem conncecting to internet with wif card

My setup
Hardware: Pismo G3 Powerbook + Lucent Technologies/Wavelan/Orinoco Silver Wifi card + 3Com wifi router
Software: OS 10.3.9 + WirelessDriverBeta5.1dmg
The Pismo recognises the wi-fi card when I plug it in: an icon appears in the menu bar showing Lucent Technologies, Wavelan/IEE. The first sign that something is wrong is that both of these options are greyed out.
The installation of the WIrelessDriverBeta5.1.dmg software was successful.
Under System Preferences/Other, there is a new preference which is "WirelessConfig"
If I click on this, the WirelessConfig preferences panel opens up fine, but everything is greyed out. Thus I cannot key anything into the box entitled "Connect to wireless network named" nor is any signal strength shown.
Apart from the above, the two LEDs on the Wifi card are both off.
Please note that this wifi card works perfectly on a G3 Wallstreet with OS9.2 on it and quite separately, that I can connect to the internet via an ethernet cable connection to my G5 which then connects wirelessly to the router,
I have followed all the instructions on Sourceforge and Versiontracker relevant to my set-up but cannot see what I am doing wrong. Any help please would be very welcome as this is intensely frustrating.

That driver is a bit quirky.
You have to use System Preferences > Network > and establish it as an Ethernet network interface ( en1, en2 but not fw0, fw1 etc.) before anything else will work. From the sourceforge FAQ:
How do I configure the WirelessDriver now that I have installed it?
1) Open the NETWORK preferences pane, select the new EN1 (or EN2) interface as the active network setting and configure it appropriately for your network (e.g. using DCHP, enter the DNS server ip addresses for your internet service provider).
2) Open the WirelessConfig preference pane and enter the Network name (this is case sensitive) and the WEP key if using encryption. If you are using a non-Apple basestation, you may want to select the text version of the hex key (see below for more info).
Once enabled in this fashion, you tend not to have to go back to the Network preference pane for this reason again, and you tend to forget about this issue.

Homehub 3 problems with wifi and network - please ...

I am hoping someone can help me, as I am struggling to work out why I am getting so many problems with my network at home.
I have BT Infinity, and a Homehub 3A. I have had BT broadband for years. Infinity was added in Feb 2013. The HH3A is the original one supplied to me years ago.
When Infinity was installed I also added a pair of TP Link powerline adapters, to provide a connection to an unmanaged network switch in the lounge.
A rough outline of what I have connected to the router is:
Wired
- Synology NAS Diskstation
- Win7 laptop
- powerline adapter
Wifi
- 3 iphones
- 2 ipads
- Win7 laptop
- 2 Win Vista laptops
Powerline / network switch
- Sonos bridge
- TV
- BluRay
- Vodafone booster
- SkyHD
Recently I am getting a number of different problems:
1) wifi drops to everything connected to the router, at the same time, all blue lights are on the router
I lose wifi connection to the internet, from all devices, at the same time, but also the connection from my laptop to the NAS drops.
2) Anything connected to the Powerline adapter is rarely available
I try and connect to Sonos, or my sky box or the TV, but they aren't connected to the router. The lights on the powerline adapters indicate everything is fine, and the HH3 has all blue lights. But my iphone and laptop cannot find my Sonos. My iphone app cannot find my sky box. And on the TV it says it is not connected to the internet. To solve this problem I have to power cycle the pair of Powerline adapters.
Some observations:
1) these problems are all since Infinity was installed. I have no idea if that is relevant.
2) My NAS Diskstation has a powersave mode. I noticed last night that when I woke it up, the powerline adapters disconnected briefly, before reconnecting. But when they did reconnect I could not access anything connected to them. It was as if the NAS had booted them off the network, and then they couldn't get back on.
3) I run a 10m brand new Cat5e cable from the infinity modem to my router, because the modem is in the garage.
Can anyone help? I am tearing my hair out with this.
Thanks for any help.

If you set the devices on the home hub to always use the same IP address, then that can help.
The problem is that when the DHCP lease expires, the home hub often gives the device a different IP address, and this breaks the port forwarding rules.
Some routers allow you to specify which IP addresses are to be reserved, but the home hub does not.
There are some useful help pages here, for BT Broadband customers only, on my personal website.

Can't share ethernet connection with PS3!

I have a wi-fi network that does not support PS3 so I am trying to share my ethernet with it instead. The thing is, everytime I turn on Wi-fi - so that I can share - it ends up trying to connect to that existing wi-fi network instead. Any ideas on how to stop this? Thanks!

I found another thread right after I posted and seem to have solved the problem following the steps described there (plus a couple more).
