Linksys WRT54G Port Forwording Promblem,
ok im sure theres prombably a million of these but it seems everytime i try to port forword it dosent work, cuz i wanna run a Private server, so how can i portforword and i can tell this by, if i put my ip in the server it dosent connect so suggestion ideas? ohh and im try to do port 90 and my isp is comcast -Thankz for any help h00psO6
If it is an issue with the Port forwarding ... check the firmware on the router ....
if required upgrade the firmware .....

Hey Guys!
I just got my AirPort Extreme Base, but I can't use my HP Deskjet F4580 wireless printer with it.
The printer is not connected to the AirPort Extreme's USB port. It is placed in another room, and I'd like to use it (the printer) wirelessly (not connected to the USB port os the AirPort Extreme), as I used to. There is no place for the printer close the AirPort Extreme. It worked just fine with my previous wireless router (Linksys WRT54G). I'm very disappointed with the AirPort Extreme Base Station because of that!...
Can you help me? Please?!
Thanks Folks!This must be a tough one, no suggestions at all.

Port forwarding to different ports on the Linksys WRT54GS.
As you can guess, I have a Linksys WRT54GS wireless router...one of the original 1.0 versions with speedbooster. Behind this router I have my standard set of machines with dedicated IP's and a set number of IP's for additional devices to acquire IP leases dynamically via DHCP should I bring them home. One of these machines with a dedicated IP is my Debian file server. This machine is headless and without keyboard. It just sits in the corner of a room and hums along. I use SSH to remote into the device to perform maintenance, shutdown, restart, etc.
My question is this. I would like to know if the WRT54GS can be configured with "unassigned" WAN facing ports (such as 7468) to forward to "assigned" ports such as 22 which is used for SSH. In this way I can leave the default settings for SSH on the Linux machine but have 7468 as the SSH port when connecting from other computers on the Internet. My goal here is to reduce any script kiddies or other malicious code from being able to target the well known port 22.
In the Games & Applications setup you can find port forwarding and port triggering. It appears that you can only forward by port range. See this link. It gives a start and end to the port range. This appears to only forward a range of ports to the destination IP which is not really what I want to do. Do I need a hacked firmware version to accomplish this?you can set the same port number on the port range...
as for the assigning a specific port for a specific machine, I doubt if it's possible with the a Linksys router...you may need a hacked firmware for this. Or you can DMZ just on the Linux.. -
How to hook up a Linksys WRT54G to Motorola NVG589. PLEASE HELP!
Hello, I have recently switched over to AT&T Uverse and I am loving it. One thing I miss is having extra ethernet ports to plug in my desktop computer and my Xbox 360. When the Uverse technician came in, he installed a Motorola NVG589 modem that also has a built in wireless router. He also installed a VAP2500 as a receiver for 2 wireless TV boxes. The VAP2500 plugs into the back of the Motorola NVG589. 3 other TV boxes are plugged into the back as well. My dilemma is the fact that all of the ports are being taken up. I need at least 2 more ethernet ports free so I can hook up my Xbox 360 (my model doesn't have built in wifi) and my desktop computer as well. I told the technician this when he installed the system and he told me to go on ebay and buy 2 cheap splitters and split 2 TV boxes that are coming into the NVG589. I did so. It didn't work out. I called up AT&T and the guy over the phone said that was the worst thing I could've done. He told be I should buy an ethernet switch. I had my Linksys WRT54G (Version 6) router laying around at the time and realized that it had a built in ethernet switch. I want to get this to also function as another Wifi hotspot because I have an old PowerMac G4 downstairs that won't connect to the NVG589 for some reason (it says connection timeout). I am guessing that the wifi card in the system may be too old to connect to the modern NVG589. So, I need the 2 extra ethernet ports and another Wifi hotspot from this setup. I have tried multiple things to get this to work. The closest way I could get it to work was when I plugged an ethernet cable from the LAN port on the WRT54G to port on the back of the NVG589. I then plugged the TV box ethernet cable I had to disconnect into the second LAN port on the WRT54G as well as plugging my Xbox 360 into the 3rd LAN port and my computer into the 4th LAN port. This worked great for the TV box and the Xbox 360. However, the computer's ethernet connection ran very slow and the WIfi from the WRT54G was very slow as well. The Wifi from the NVG589 was slow too. I unhooked that setup and put it back to what it was beforehand. Is there anyone that knows of a flawless way of setting this up? Any articles someone can link me to? I've heard of bridging the NVG589...would that help me? How exactly would I do that? Please HELP. I have attached pics. On the back of the NVG589 - green ethernet is the DSL cable, both white ethernet cables along with the black one are TV boxes and the yellow ethernet cable is the VAP 2500. Thanks!

Ya, the install tech must have been sleeping or texting or something during training.... or it's possible he misunderstood you and thought your were talking about needing extra phone ports, which could be accomplished with simple splitters. You were almost where you needed to be with your setup, you just missed some steps. Connect your wired computer only to one of the Linksys' LAN port. With the Linksys powered up press and hold the reset button for 15 seconds (will need toothpick or unfolded paperclip). This will perform a "factory" reset. When the Linksys is fully rebooted, log in to the Linksys. Do not configure the "Internet Connection Type" on the Linksys. Navigate to the "Wireless" section on the Linksys and configure the wireless. Do not use the same SSID (wireless network name) that the NVG589 uses. Save changes. Navigate to the "LAN" configuration on the Linksys and set the routers address to 192.168.1.1 and disable the DHCP Server. Save changes. This step will kick you out of the router. Power down your computer and the Linksys, run an Ethernet cable from a LAN port on the NVG589 to a LAN port on the Linksys, then power up the Linksys, and when it's fully rebooted, power up your computer. You should be good to go at this point. You will want to individually configure your wireless devices to use either the wireless network from the NVG or the wireless network from the Linksys. Otherwise they make keep jumping back and forth between the two, which will degrade performance for that device. You may still notice a slight to moderate performance drop for the wireless on both the NVG and the Linksys because they will be competing for the same wireless airspace along with the VAP2500.

How do I configure my Airport to work well with a Linksys WRT54G?
I have DSL Extreme coming into my house in bridge mode. (Don't know the specifics, but they said that's how it has to work.) I had my Airport Extreme connected to the modem, sending out a nice wireless signal.
I was given a Linksys WRT54G Ver. 6 wireless router, and I thought I'd use it as the main router connected the modem. I also want to use it as a wireless access point for one half the house for b/g devices AND I also want to set up the Airport Extreme as another wired access point for the other half of the house for n devices.
So, I set up the Linksys as the main router sending out a wireless signal on channel 1 for b/g devices. I connected the WAN port of the Airport to one of the open LAN ports on the Linksys, changed the Airport to Bridge mode, and set up a new wirelss network to broadcast on a different channel. Unfortunately, this isn't working. Only the Linksys wireless is working properly, i.e. connected to the internet. The Airport broadcasts the wireless signal, but it isn't connecting to the internet.
I've tried changing the IP address of the Airport to one that falls within the range of the Linksys (192.168.1.x) and making sure that the subnet of the Airport is identical to the Linksys. I've also added the DNS servers, although I'm not sure why the Airport Admin Utility asked for this. Regardless, nothing works. I'll get a green light, but there's no connectivity to the internet.
I've also tried connecting to a LAN port and not the WAN port on the Airport. No joy there.
I've read through numerous threads, and they all seem to indicate that my original set up should work. I've upgraded my Linksys firmware, to no avail. I don't want the Airport to be a repeater as there is a reduction in speed. I want to have two separate wireless access points.
Thanks in advance for any and all help.Ok, I got you. Prior to the introduction of the simultaneous dual-band routers, the only way to mimic them was exactly what you are trying to do. Connect two routers by Ethernet and create separate wireless networks to allow clients to connect to either as appropriate.
You are also correct that the upstream router (Linksys) should have both NAT & DHCP enabled and that the downstream router (AirPort) be configured as a bridge. The only recommendation is to set the AirPort's static Private IP address to one just outside of the Linksys' DHCP server range instead of inside it to prevent the same IP address being handed out to multiple clients.
You could do this a number of ways, but the simplest would be to use the Configure IPv4 = Manually option on the TCP/IP tab within the AirPort Utility. Use the LAN-side IP address of the Linksys for the Router Address, and the appropriate DNS server addresses (either your ISP's or a service like OpenDNS). The Domain Name field can be left blank.
Since the AirPort is in bridge mode, it really doesn't matter which Ethernet port (WAN or LAN) you connect the Linksys to, but for consistency, I would recommend the WAN (circle-of-dots) port. -
Insufficient Bandwidth Linksys WRT54G 2.2
IChat 3.01 works fine if I connect my computer directly to my Comcast cable modem. When connected through the WRT54G I can text chat but audio chat attempts produce the dreaded "insufficient bandwidth" message. I updated the Linksys to v4.20.7. I have tried to open ports as listed in some of the other posts on this problem. I have selected Upnp enable, and Upnp disable. I have selected DHCP disable, and enable. I have reinstalled the 10.4.2 update. I have repaired permissions. In short, I have tried to utilize every fix detailed in the hundreds of messages offering fixes. Since iChat works fine without the Linksys in the mix, I am inevitably led back to the idea that somewhere I have a mistake in my Linksys setup. Has anyone got a setup guide for v4.20.7 firmware of the Linksys WRT54G that will help me step through each and every setting required to get this thing working? Or is this device just not going to ever work with iChat? Thanks in advance for your help.
I have the WRT54G (Ver 4.0/4.20.7 firmware). I have mine configured with UPnP only which opens the following ports: 1024 to 5000 Both TCP and UDP.
Try configuring it only with UPnP enabled(Take out all of the port forwarding and port openings, Unplug your modem, router, and mac and then plug them in in this order: Modem (then wait a minutes or two),router (then wait a few seconds), and then your mac and give that a go.
Then try testing with a known working screen account. (My screen name is in my profile if you want to test with me)
I've noticed the WRT54G isn't real good releasing ports from UPnP without rebooting.
That's how I got my WRT54G working and I can now chat with both Mac and PC's.
Hope this helps!
P.S. I have my mac firewall off. -
Linksys WRT54G Wireless-G Router Not working
I have a Linksys WRT54G Wireless-G Router and it has worked good for a couple months and yesterday it stopped. When I plug it in all the lights are lit even though there arent any ethernet cables connected and the power light blinks constantly. I tried holding the reset button on the back and it didnt help. Anyone know whats wrong or anything I can try to fix it?
You need to try again to reset the router to factory defaults.
To reset your router to factory defaults, use the following procedure:
1) Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping 192.168.1.1" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.
If you cannot get "Reply from ..." in step 9 above, your router is dead.
If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. In this case, use the Linksys tftp.exe program to try to reload your router with the latest firmware. After reloading the firmware, repeat the above procedure starting with step 1.
If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.
Please let me know how things turn out for you. -
I have a Linksys WRT54GS wireless router that has stopped working. All it will do is all 4 of the Ethernet port lights on the front light up solid green along with the Internet light. Is there any hope of fixing this?
It wouldn't make that much of a difference, but I already purchased a new LInksys Cisco EA3500, but I cannot get it to do my port forwarding. I have tried everything and nothing works. Have spent hours on the phone with tech support with no solution. My old WRT54GS just simply worked. The port forwarding worked perfect. I have tried the exact same setup in the new EA3500 and no luck no matter what I try.
So, is there anything I can do to get the old WRT54GS working?darkcyber wrote:

Hi darkcyber.
What happened to the router by the way? Have you checked the power cord if it is the correct one? I already checked on their website and the PSU for this model is 12V 0.5A. You can try to reset also the device for 30 seconds and unplug it after for 30 seconds also and if it is the same thing then perhaps you can try another power outlet to see if leds will lit up properly. -
Need Help Streaming Video From Web Server Built Into Application - Linksys WRT54g Router
Very much appreciate any help getting streaming video feed from web server built into video application to work properly using port forwarding on my Linksys WRT54g wireless router.
Here is the situation:
My PC is connected to the internet via a Linksys WRT54g wireless router.
The Windows XP Pro SP2 firewall is enabled, with a firewall exception established for the video camera application.
On the router, forwarding of port 80 is enabled for the LAN IP address of the PC running the video application with an embedded web server, and the web server in the video camera application is also set to use port 80.
I have a free DYNDNS account and also run the DYNDNS updater program on the PC running the video application with embedded web server. According to the DYNDNS web site and the DYNDNS updater program, the IP address assigned to the machine running the video application with embedded web server is set correctly in my dyndns account.
When I open a browser (Explorer or Firefox) on the PC running the video camera application with embedded web server, I am able to connect to the video application's web server by going to the dyndns address linked to the machine running the video application. The video application's web server is set to use the dyndns address. That's the good news. The bad news is that I can't connect to the video application's web server from any machine that connects to the internet that uses a router other than the router used by the PC running the video application. I am only able to connect to the streaming video from the application's web server only on machines that connect to the internet using the same (home) router used by the PC that is running the video application.
Since I am able to connect to the video app's embedded web server successfully on the machine running the video application, it seems that at least something about the current port forwarding settings is correct. For example, if I uncheck 'enable' for forwarding of port 80 on the router settings page, I am no longer able to connect to the video app's web server when I try to do so in a browser running on the machine running the video app. When I re-enable port 80 forwarding on the router, I am again able to connect to the web server of the video application on the machine running the video app. I thought that by enabling forwarding of port 80 on the router and associating that port with the LAN IP of the machine running the video application, it would be possible to connect to the streaming video of the video app's embedded web server from ANY machine connected to the internet, but that is not the case. There must be some other router settings to update/change in order to get the port forwarding working to enable a successful connection to the video web server, but I am stumped. Very grateful for any suggestions as to how to get this working properly.
Thanks in advance...The firewall log can be configured on the third tab in the window for the firewall settings, where you can turn the firewall on and off completely.
From your tests, though, it does not seem to be the firewall. However, to be sure, it would be good to check the log. It will help to eliminate the firewall as the culprit and you may find it handy in the future, too. ;-) Just don't forget to turn the log off again after you are done because it may cause some performance penalty on your system while on.
From what you write, it seems as if I should give a little networking background on the ip addresses you'll see. Your setup is (or should be) a modem connected to the WAN/Internet port of the WRT. The computer is connected into a LAN port of the WRT.
Your router has two IP addresses (that's what makes it a router): a WAN address and a LAN address. The WAN address is the address assigned by the ISP. It is a normal internet IP address. Everyone is able to send packets to this IP address. The WAN address is the one reported by whatismyipaddress.com, it should be listed in the dyndns record and it is the address that your router shows on the Status page. It's the public IP address of your router. Dyndns maps your dyndns.org name to that IP address.
Your router also has an IP address on the LAN side. You can configure it to be whatever you want. The default is 192.168.1.1 with netmask 255.255.255.0 and it is better to leave it like that or at least inside the network 192.168.*.*. 192.168 is a special, reserved IP address range for private networks. Basically, routers in the internet are not supposed to forward addresses in this range. That makes them suitable for private LANs as the packets never can get anywhere. Most people using Linksys routers have there LAN in 192.168.1.*.
The router acts as gateway, which means it forwards packets from PCs in the LAN to the internet and back. As all your PCs in your LAN share a single WAN IP address, the gateway does address translation (NAT). This works only in one direction: from the inside to the outside. The router remembers when a PC in your LAN sends something out and accepts the responses in and sending them back to the PC. If something comes in from the internet which cannot be associated with a ongoing communication the packet is dropped unless you use port forwarding.
All computers in your LAN either have a static IP address assigned or use DHCP to get it automatically. The router has a DHCP server as well which gives out IP address from 192.168.1.100-149 if not changed. With a router with default settings static IP addresses can be in the range of 192.168.1.2-99 and 150-254.
ipconfig /all reports your IP address in your LAN, i.e. an address 192.168.1.*. The gateway in this output should be 192.168.1.1 which is your router. And packet no in the LAN address range 192.168.1.* is send to the router which forwards the packets into the internet.
An address 192.168.1.* should not appear as internet address in the Status page of the router nor should it appear at dyndns.
Port forwarding is used to operate a server in the LAN. By default, a server in the LAN cannot be reached from the internet. You have to configure port forwarding for this. You configure that traffic bound for a specific port (e.g. TCP port 80 for http) on your WAN IP address is forwarded to the same port on a specific LAN IP address. If your server runs on 192.168.1.50 than traffic to your WAN IP address port 80 is forwarded to 192.168.1.50 port 80. That way your HTTP server can be reached from the internet. As you can only configure a fixed IP address in port forwarding it is recommended that the server uses a static IP address and not DHCP as in the latter case the IP address may change over time...
O.K. so much for networking. I hope that makes things a little clearer and you can verify that your setup is how it is intended to be.
I suggest the following: on the router's security page there is an option to block WAN requests. Remove the check if it is set (meaning: do not block). After you did that change you should be able to ping your WAN address (e.g. ping xxxx.dyndns.org) from the internet. That way we know that it is on the correct address.
Also on the Administration page make sure that remote management is disabled (should be like that per default) or that the management port is NOT 80 but for example 8080. What is your your UPnP settings on the same page?
O.K. that should be enough for the moment... -
Linksys WRT54GS Version 6 router help
Hi all! I have a Linksys WRT54GS Version 6 router with Firmware Version: v1.50.6 and I was wondering if anyone could help me find a free log viewer, since the log viewer that comes with the router just gives the last few sites outgoing and incoming, and it doesn't time it either. Anything that will work with my router that will record all day info as well as put the time? I'd also like it (if possible) if it could identify which websites those IP's belong to; sometimes I will put an IP in the address bar and nothing happens or I get an error.
Also, I can't seem to be able to telnet into my router. I put the right IP 192.168.1.1 8080 which is the port that shows under Administration/Management "management port:" 8080. When I telnet (I'm using vista and I installed the telnet client and server) it says connecting and then just sits there for a long time and then asks me to push any key and says connection timed out. I also tried with port 80 and 23, nothing.
Thanks!*BUMP*
I gathered from what I read on the 'net that this particular router pretty much sucks in terms of putting 3rd party firmware, of telnetting into it, etc. So, is it basically true that there is no way to telnet into this? Also, no one knows of any monitoring or log viewer that works with this version?? Please?

I recently moved into a new home with a roomate and our DSL box is 4 port wireless router. One desktop is hardlined into that, my laptop has no problems keeping a good connection to it wireless, but my PC in the back bedroom frequently drops connection... and I'm getting really tired of /release and /renew. I have a Linksys WRT54G v6 wireless router and was wondering if there is someway I can use this product to boost my signal to the DSL box. I'm kind of computer savvy but this is stumping me. I hardlined the DSL box into the Linksys from one lan port to the other (not the uplink) and it seemed to be working ok except for the PC that's hardlined into the DSL box. The other two wireless comps were working fine. Any advice would be greatly appreciated... I really just want to boost the signal a little bit so I have a steady connection. Thanks in advance,
My PC is on the other side of the house as the router, the laptop in the middle room, and the router and other PC is in a room with the router. The channel on both routers is 11 because I've encountered problems with phones before. Its definitely a signal issue because I always connect with low signal strength and frequent drops. The Linksys has a stronger antenna than the DSL box does which is why I'm wanting to use it as an AP, even if I have to hardline it into the DSL box. Thanks for the reply.

Hi guys, just want to drop some questions around here, hope to have some great responses! Just recently, I've configured Linksys WRT54G as a wireless access point and it's working fine, as well as i enable WEP and MAC filtering security. Now, I've also connected some user through LAN which i doubt to have no security and can easily connect to the internet without MAC filtering or any security authentication. How will i configure this router to filter/restrict the LAN users to access internet? Is it possible? I would appreciate any help from this concern. Thanks, Mike
The WRT54G is designed for home or small office use. Because of this, the wired LAN ports on the router are protected only by "physical security", that is, they are protected because you only allow "trusted" people to come into your home.
Anyone who plugs their computer into a LAN port, will be able to access your network.
If you know the MAC address of a computer, you can use "Access Restrictions" in the router, to deny them access to the Internet. But they will still have access to your LAN.

Link 2 Linksys WRT54G together
Our office has 2 connections to the internet. Each connection comes into our building through a Linksys WRT54G router. I like to connect the routers together through their ethernet ports so that we can share resources such as printers and etc. Should I config each router such that they are actually on the same network? For example:
Router 1:
Router IP 192.168.1.1
DHCP serves 192.168.1.100-150
Router 2:
Router IP 192.168.1.2
DHCP serves 192.168.151-200
Or do I have to configure each router to be on its own network and set up some form of routing between the routers?There are two ways to cascade a Linksys router to another Linksys router:
Connecting one of the Ethernet ports of the second Linksys router to one of the Ethernet ports of the main Linksys router.
Connecting one of the Ethernet ports of the second Linksys router to the Internet port of the main Linksys router.

Help protect my Linksys WRT54G from the "curl" command which bypasses my security settings
It's way too easy to break into my Linksys WRT54G router!
Do you have firmware that will fix this vulnerability?
Instantly bypassing the administrator password, my fifteen-year old
neighbor broke into my Linksys WRT54G router (firmware revision v1.0.0.6)
in ten seconds simply by sending this one "curl" command to it via the
Internet from his home next door!
c:\> curl -d "SecurityMode=0&layout=en" http://192.168.0.1/Security.tri
This kid was kind enough to knock on my door today to tell me to fix it.
I invited him in, and from inside my own house, he showed me the Linksys
WRT54G command above which immediately disabled all my wireless security
WITHOUT him having to enter any password!
He showed me how to disable remote administration but he said the
vulnerability still exists until I get a new router. I can't believe
everyone with a Linksys WRT54G router is throwing it in the garbage.
Where/how can I find a firmware update that protects me from this curl
vulnerability?To protect your router:
* disable remote management.
* enable WPA2 or WPA with a strong preshared key on the router.
That is essentially all you must do. This protects against the curl problem (from the outside). The benefits of the rest varies:
* set a strong, hard to guess password on the router.
That's always a good idea to prevent some guest coming over, plugging into your network and modifying the router. For that to be relevant the person either needs physical access to your wired LAN or the WPA key.
* disable UPnP
Good idea if you are worried you could install some malware on your computer. UPnP allows to set port forwardings for incoming connections from the internet. It allows a computer to automatically setup the forwarding to make a server accessible in the internet. You'll often need this for gaming. But it obviously can be exploited by malware.
* access server to https instead of http
With WPA in place on the wireless this is only really necessary if you worry about someone gaining physical access to your router. https protects the password transmission to the router. But then, if someone gains physical access to my router I think the protection of my password would be the least of my problems.
* disable wireless access to the router configuration
For this to be effective with WPA in place would require the attacker to crack WPA to get into your WLAN. WPA is considered secure at this time. Anyone cracking WPA with a strong key must have a lot of computing power and a lot of knowledge. I don't know if this setting would really prevent that attacker of gaining full access to the router. This setting may be useful if you have an occasional guest to which you grant wireless access to the internet...
* changing the default IP address from 192.168.1.1 to something else and turning off the DHCP server on the router
With the DHCP server in place changing the IP address is no mean of protection because the DHCP server assigns a correct IP address in your LAN. You have to setup static IP addresses on all computers and devices. However, if someone gained access to your LAN (wireless or wired) all you have to do is wait and listen to the LAN traffic. It usually takes a few seconds until some noisy windows computer will broadcast a message and you have picked up the IP addresses in the LAN
Some more things often mentioned with questionable benefits:
* turn off SSID broadcast
Supposed to make the WLAN "invisible". O.K. It does make it harder for the average Joe to check what WLANs are in the neighborhood and which channels they use to optimize the choice of channels and limit interference. It does also prevent accidental connection attempts. However, with WPA/WPA2 in place the WLAN is protected anyway. Anyone, who really wants to know if there is a network can scan with a wireless card in monitor mode. The SSID is transmitted unencrypted. Plus in average it requires more times and more power (on laptops) to connect to the network as the wireless card must actively try to connect to each configured WLAN on the computer to find out if the network is there or not. With SSID broadcast it simply scans for broadcasts and then knows the network is there...
* wireless MAC address filtering
Supposed to limit the computers which can connect to the WLAN. Only computers with the MAC address on the list can connect. Again, this only prevents accidental connection attempts. MAC addresses are transmitted unencrypted. It is easy to pick them up with a wireless scanner. Thus, for anyone who knew how to crack WPA the MAC address filter list will be the least of problems. Most wireless cards can be configured with any MAC address you like. But the list increases the amount of effort for you to add another wireless computer to your WLAN as you always have to remember to set it up correctly...

?WSDL for Business Service or WSDL File
I know that you can append a ?WSDL to the end of a Proxy Service to access the WSDL File for the Service. Is there a REST/GET way to do the same thing to access a Business Service or a WSDL or a Schema directly? Thanks, Jay
