WRT54G as a wireless switch

I am using a D-Link DSL-2640B as my primary DSL modem/router at home, but the wireless coverage doesn't reach my entire house. Can a WRT54G (v6) wireless router be connected to the D-Link via ethernet cable and used to broadcast a second wireless network that provides internet access through the D-Link's connection? I know there are devices designed specifically for extending wireless coverage, but I have a WRT54G lying around and I'd love to avoid buying new hardware if possible.

1. Wire a computer to the WRT. Open the web interface at http://192.168.1.1/
2. On the main setup page, change the LAN IP address from 192.168.1.1 to a free IP address in your D-Link LAN.
3. On the same page disable the DHCP server.
4. Save settings. You'll loose the connection.
5. Now wire one of the numbered LAN ports of the WRT to your main router.
You now use the WRT as simple ethernet switch and wireless access point. You can configure the WRT through the web interface at the new LAN IP address (step 2 above).
For a wireless roaming network set identical wireless settings on the WRT and your D-Link. SSID, wireless security (WPA2 Personal) and the passphrase should be identical. Both access points should broadcast the SSID. Assign different channels on both routers, at least 5 apart (e.g. 1 & 6).
Also remember to change the default password of the WRT ("admin") on the Management page.

My pavilion dv2418nr wireless switch light stays orange

My pavilion dv2418nr wireless switch light stays orange, will not go to blue, will not recognize any surrounding neighborhood connections. ISP says the router is fine, that it is the laptop switch not allowing the wireless card to read any connections. HP tech had me connect the Ethernet cord from the router to the laptop....I got on internet fine...however, that's a hard connect. Has anyone had this problem with their switch? i think until that little light turns blue I'm out of luck. Thanks for you help

Wrt54g as a wireless card

I have a wrt54g running my wireless network, can i use another wrt54g as a wireless reciever to add another computer to my system?

No.. You just need to get an extra wireless adapter, it can PCI/USB wireless adapter for desktop computer user or wireless PCMCIA card/USB wireless adapter for laptop user (check first, most likely there is built-in wireless adapter on laptop).

X60 Micro Wireless Switch

I have an X60 (1706) that is pretty darn old and has worked great for years. I believe the micro wireless switch has failed on it. Mechanically, it works but I assume it has failed electronically. I have been having issues on and off (no pun intended) with it for a couple of months. I took the laptop apart and it appears that the switch needs replacing. In Linux live CD boot, it says the wireless switch is off.
I assume the part is not an FRU. Is that correct?
A replacement motherboard is the only thing?
Solved!

OK, but you could still solder a shunt (or even just wrap a few strands of fine wire) across the switch. I can't recall the last time I actually had the need to turn the WiFi/BT radios off using the mechanical switch. Besides there's always Fn-F5.
It's also possible that the reason why the switch works intermittently is because the plastic button is broken. If that's the case then the eBay solution would address that.

Dhcpcd consumes a lot of CPU when wireless switch is off

If I turn my hardware wireless switch off, dhcpcd goes crazy and uses a CPU core completely. Checking with htop, the command being run is:
dhcpcd -4qL -t 30 wlp13s0
where wlp13s0 is my wireless interface. I'm using netctl-auto to connect to the network.
It goes back to normal as soon as I turn the switch back on.
The network configuration under /etc/netctl to which it was connected before I turned the switch off is
Description='Automatically generated profile by wifi-menu'
Interface=wlp13s0
Connection=wireless
Security=wpa
ESSID="network"
IP=dhcp
Key="password"
Is there anything I can do so that dhcpcd won't try to use all my CPU in such cases?
EDIT (2014.05.28):
I looked in the following wiki pages, but couldn't find anything about this issue:
https://wiki.archlinux.org/index.php/Br … leshooting
https://wiki.archlinux.org/index.php/Dhcpcd
https://wiki.archlinux.org/index.php/Ne … figuration
https://wiki.archlinux.org/index.php/Netctl
I couldn't find anything about dhcpcd and cpu usage in the forums, and searching the web didn't provide any relevant results. Which is bad, since anatolik found this:
https://bugs.archlinux.org/task/39512
which I didn't.

If I turn the switch on after turning it off, I must connect manually using netctl (that is, netctl-auto doesn't connect automatically in this case). After doing that, turning the switch back off does not cause the problem. Which is weird, since the process is still there, like before
I also noticed that it is no longer possible to use netctl-auto after turning the switch off, as it no longer see any configuration (running `netctl-auto list` as root returns nothing, while before it returned 2 items).
ondoho wrote:how did you install and activate wireless
I basically followed this wiki page:
https://wiki.archlinux.org/index.php/Ne … f_profiles
I first generated the profiles with wifi-menu and by copying /etc/netctl/examples/ethernet-dhcp, and then activated netctl-auto using
# systemctl enable [email protected]
# systemctl enable [email protected]

Yes, it looks very similar. It is said there that the problem should be fixed since 2014-04-01 11:48:57, but I just checked for updates with pacman and I already have the most recent version (6.3.2). I will see if I can add any relevant information to that page.
I did notice that my wireless interface disappears when I turn the switch off (ifconfig doesn't show it anymore), and it only reappears when I reconnect manually. I'm not sure if that is expected, since the commit that should have solved the problem says:
On a read error, remove the FD from eloop. This shouldn't happen really

Hows it going every one? I have a WRT54G V8.0 wireless router, and I tried to update it's firmware earlier and I guess I failed miserably! The thing wont network, wont let me into thelinksys GUI toconfigure anything. But all the lights work... and it wont let me go into administration mode either to force the old firmware back on. I am really stuck so if anyone knows how to re-flash a router without the routers GUI or something similar, that would be of great help... thanks!
-Stephen.

there seems to be consistant issues with Linksys routers according to all the posts ive been reading for the past month while i try to fix my on and off again internet connection. its becomming very annoying. i have asked my cable company to replace my modem, which they did and that didn't even help. last year i bought a new linksys router thinking it would solve my problem back then. it did for a while, then my lap top wouldn't connect any, so i sent it into have it checked and it came back with no problems. soooooooooo apparently, while i am connected to my neighbors open connection from his BELKIN ROUTER and even though the signal is very weak............amazingly enough!! i am still online while typing this.......funny eh?? WELL........it seems to me......that i guess i wont be buying linksys anything anymore. Especially after spending hours on the help line (INDIA) trying to reset channels and reset the router box itself. i give up.......i have 2 pieces of crap routers for sale cheap......any takers? dont waste your time

WRT54G ... wireless not working.

I've had this router for about a year or two now, and have had NO problems at all.. until the other day. My wifes laptop Hp pavilion dv2500 used to connect wirelessly to this router and surf just fine, but now it can not connect at all or when it does it has zero bars of connectivity. At first i thought it was the network card so i uninstalled and re'installed the drivers. No luck. I tried to release my wireless ip address however it would come up 169.XXX.XX.x.x to that effect. Then i remembered that my phone has wifi and i've used my router to connect to the internet, but my phone could not connect either. Neither could the wireless network card on my desktop. The router works fine when connected to with a network cable. Please help me any way you can. Thank you all in advance.

Check first the wireless settings on your router ... also make sure that the wireless switch on the Laptop is turned on ....
if so then changethe network name to any non-linksys name ... & also use any security key ....
Check on the laptop if getting connected or not ....

Wireless switch daq

I am interested in using a wireless switch to indicate whether a device is holstered/unholstered. I found the following switch which I think would meet my needs. http://www.walgreens.com/store/product.jsp?id=prod3447901&CATID=304722&skuid=sku3446744&V=G&ec=frgl_559044&ci_src=14110944&ci_sku=sku3446744
How do I tap into the on/off state of the light receiver and input that data into labview? Obviously when the switch is on, the receiver circuit outputs a voltage. How can I measure this voltage & input it into labview? What data acquisition card do I need and is there anything else I need to convert this voltage/lack of voltage into something the daq can read & understand?
Thank you.
-Adam

Hi Adam,
I like the way you think! I once modified a cheap programmable appliance timer to switch AC based on a parallel-port output pin (using LabVIEW, of course.)
I expect if you crack-open and probe-around in the "light receiver" you'll find some TTL level signal that indicates whether the light is on or not. BE CAREFUL to identify and stay-away-from the AC side of things!!! Also, while probing, be very very careful not to accidentally short-together any signals - especially neighboring pins on ICs.
If you're lucky, you'll be able to (find and) wire such signal to a PC parallel-port input without affecting the operation of the light.
I think appropriate voltages for the parallel port are 0-5V DC. If you find a signal in the -12 to +12V range, consider using a COM port instead.
You can find examples on this forum to use VISA to read parallel port signals or COM port signals.
Luck/Cheers!

X201 Wireless switch Hardware problem - PLEASE HELP

Hello everyone,
I have been a regular reader of this wonderful forum and have also participated on a few questions. I have an x201 which I bought from UK 6months back.
After a smooth sail for many months and just when I thought life was going good, I have a wireless switch problem that pops up out of nowhere. I never use hardware switch and had to do it only last week because of checking for my internet connection problems.
Only once in my entire experience with this laptop that I put it off, now it has become so sensitive that even shaking the laptop while typing turns off the laptop. On reading about this problem I found out that it is quite a common problem with x-series and has many users affected from it. After confidently calling the customer support they ask me to pay 200euros just to "TAKE A LOOK AT THE PROBLEM"????. Apart from at least acknowledging the persistent problem across all the models they end up asking me to pay for everything and cannot tell me how much it will cost me or even tell me how long it will take to replace this.
Is there any other way to do this? The support told me that the only other way to repair this will be to buy the Base switch myself and then replace it. I am a biologist doing my PhD and have no knowledge of all these. Apart from all the appluad this laptop got from my colleagues, now they all think this is a joke by Lenovo to be charging for something that is entirely their mistake.
Can anyone point to a solution please and help me. I was really looking to buying an ultrabook next year but looks like replacing a switch is going to cost me 1/4th of what one would be for an entire laptop.
PLEASE HELP

Do Mac Laptops Have Wireless Switches?

Hi All,
I was hoping to pick your brains: I’m doing a wireless Internet, technical support flowchart but I only have access to one laptop. I know that (all?) PC laptops have wireless switches, do Macs?
Thanks in advance:-)

Jay is correct, but seems blissfully unaware of what the average PC user has to go through.
I know the switch you are talking about and it doesn't exist on any Mac and probably never will. If you need to turn Airport or Bluetooth off, use the icons in the menu bar or go to System Preferences.
