Is there any way to beam a wifi signal from wifi router to wifi router?

Question

I was wondering because i have a friend down the street who's going through some finacial troubles so i wanted to help em out be sending em my wifi connection to their house so that they don't have to pay money for an internet connection. problem is that their house is too far away for my linksys router to reach. so i was wondering...is it possible to beam it close to their have some other router intercept the signal and beam it farther at their house so they can use it? i just wanna help a friend in need.

Answer 1

Here is a linkk explaining using Linsys WRT54G routers.

===============================================
Standard terminology for a two router setup:

* The client router is the router which does not have an internet connection.
* The host router is the router which does have the internet connection and is going to share it with other routers.

[edit] Two or more WRT54G / WRT54GS / WRT54GL boxes
[edit] Setup

1. Save the configuration on both routers: Administration -> Backup. Click "Backup" button and follow prompts so save nvram backup files, i.e. nvram_host.bin, and nvram_client.bin. The configurations can be restored if the setup doesn't work out and you need to quickly get back to a different (working) configuration.
2. Reset both routers to factory default settings so other settings will not have a possible conflict: Administration -> Factory Default - select yes - click "Save Settings" button.
3. Give both the routers a different IP address, i.e. 192.168.1.1 (host/internet gateway) and 192.168.1.2 ("client router") on the same subnet. Setup -> Basic Setup
4. Change the Internet Connection Type to Disable on the client router. Setup -> Basic Setup -> Internet Setup -> Internet Connection Type -> Disable
5. Set the Gateway IP address of the client router to the LAN IP address of the host router. Setup -> Basic Setup -> Network Setup -> Router IP -> Gateway
6. For each router, under Setup -> Basic Setup -- Network Address Server Settings (DHCP) -- Start IP Address, you may want to set different starting address for the different routers. For example host 192.168.1.1 starts DHCP at 100 and client 192.168.1.2 starts at 200. This will allow you to enable DHCP on both routers and know which router you are connecting to. This is helpful when connecting to your network with a wireless laptop so you know which router it is connecting to and for changing wireless power settings (both laptop and routers). Alternately, you can disable DHCP on the client router(s) and have only the gateway perform DHCP services.
7. On the client router, under Setup -> Basic Setup -- Network Address Server Settings (DHCP) -- Static DNS 1,2,3 enter the DNS settings provided by your ISP. These can also be found from the host router under Status -> Router -- Internet.
8. Turn off the firewall on the client router. Security -> Firewall -> Firewall Protection -> Disable
9. Turn off security on both routers (this should already be done if you reset as above). Security can be re-enabled after all other steps are complete, but in order to minimize troubleshooting, it's best to get things setup with no security active. Wireless -> Wireless Security -> Security Mode -> Disabled
10. Put both routers into AP mode and on the same channel. Wireless -> Basic Settings
11. Under Wireless -> Basic Settings, set the SSID to your liking. For WPA WDS, the SSID for the routers needs to be the same. For WEP, different SSIDs can make troubleshooting easier.
12. If you plan to use WPA later, then select G-only in Wireless -> Basic Settings. You cannot use B-only with WDS.
13. Open WDS configuration on both routers. Wireless -> WDS
14. On each router, you will see its wireless MAC address at the top of the Wireless -> WDS page. Put each router's MAC into the table of the other router, and select LAN for the type. Note that this MAC address is different from the one that may be printed on your case!
15. There is no need to enable Lazy WDS or WDS subnet on either router.
16. Test that you can ping the gateway from the client. Note that it may take a short amount of time for the WDS to be established, and you may need to reboot both the gateway and the client.
17. Enable encryption now, if you like (highly recommended).

[edit] Notes

* In some cases it may help to put the IP of the client router as a DMZ'd machine in the host router. Of course, this only works with a WDS between 2 routers.

* If you have G-only enabled, you must use channels 1, 6, or 11.

* The source material for this list comes primarily from the following DD-WRT forum posts:
o Guide to Setting up WDS.
o http://www.dd-wrt.com/phpBB2/viewtopic.php?t=124
* If you're using encryption, remember to configure it on all routers!
* On the main Status page and the Wireless Status you can see the signal strength for any other routers in the WDS. If they are showing 0 then you're not connecting to them for some reason (wrong MAC address or, for WPA links, wrong SSID).
o It seems that when WPA2 is enabled, WDS does not work well with TKIP+AES: client router reports no signal from the host router, while the host router reports a valid signal from the client routeur. Using TKIP only helps.
o WPA2 is works fine with TKIP+AES: Set both client and host to the same security settings, with the same password. Version in use is v24 Beta (07/12/07) - std on 2 Buffalo WHR-G125s.

This has been studied over the previous few years via a number of experts... it is the base line: the only result we are able to diploma, is the "non-ionizing radiation" inflicting warming up of the direct ecosystem (comparable with a microwave - there of course is a extensive distinction interior the quantity of capability!). The measured outcomes of a WiFi router or hotspot shouldn't exceed 4.5 V/m - it quite is a notably risk-free decrease and could no longer reason heating of the physique to a substantial point. there have been exams with severe-radiation ( > 150 V/m) inflicting maximum cancers, cerebral and genetic harm - yet those have been with lots larger thresholds. of course, it is not a honest evaluation. To make an analogy: it is not because of the fact you get burnt via water of ninety 9°C, that it quite is risky to pour water of 38°C over your arm. Now, a number of those study have been tackling the "brief term" outcomes. because of the fact the technologies continues to be somewhat new (below 2 many years), the long term outcomes are not accepted yet. There are no longer any obvious outcomes, even even with the shown fact that it is going to no longer be ruled out. base line: we've not have been given any awareness of dangerous outcomes. yet because of the fact we don't comprehend the long-term outcomes yet, it is smart to apply some straight forward precautions. The results of the non-ionizing field without postpone drops. So in case you progression your router someplace the place it sits greater desirable than a million or 2 meter from you, you have already decreased the hazards dramatically. merely as a sidenote: for the comparable reason, it quite is a sturdy theory to no longer keep your GSM on your pocket - it somewhat is somewhat on the brink of a few physique factors that are delicate to warmth :)

Check out the D-link products. Have done it but been a long time and don't remember the product number. Takes two units interconnected, and requires power for both. They need to be at an intermediate point.
