Networking OSX airport through linksys wireless router

Zone: Apple Networking

Tags: linksys, wireless, router, airport

Okay, this one has stumped Apple, and this particular iteration of this question doesn't appear to have been asked here yet. Here's hoping...

My home network consists of a Linksys WAP/Router/4 port switch (model BEFW11S4 v.2) going to the outside world via a cable modem. I have a PC wired directly to the router, and a PC laptop that connects wirelessly. Both of these connections work without problems.

I just got a Powerbook G4 with an Airport extreme card. It cannot connect wirelessly through my router (the Apple tech double checked my setup and said that everything was cool on the client end). My Aiport internet connection tool says that the G4 finds the correct wireless network (it gives me the name and everything) and reports that I have a good signal, but when I try to connect to any web resources (even a simple ping), the request times out. When I switch over to a wired connection through the router, the G4 connects without problems.

I have the router set up for DHCP, and both the router setup and the G4 agree on the ip address that the wirless connection has been assigned. I can see the G4's wireless connection in my router's DHCP client table. The G4's wireless IP is different from that assigned for the wired connection.

Also: my network is not setup with a WEP, and I've updated the router to what I believe is the most recent firmware update, v.1.45.

I believe this must have something to do with my router setup, but I'm not exactly sure where. I don't recall fiddling with any of the settings which may have broken this, but, er, I guess I might have. Any ideas?

fhieber:

I have almost the same setup in my house. I am using the same router, with a signal booster. I have an old 233 iMac rev A hardwired to the router, a Dell Laptop that is wireless, and an 800 iMac G4 that is wireless. I found that the Dell would work with DHCP on the router, but the Macs would not. I had to set them to a specific IP address. I set the DHCP server (the linksys router) to have a scope of 3 addresses, ie 192.168.1.1-192.168.1.3. Then set the Macs with different IPs within that scope. You'll also need to add the DNS addresses, the gateway, and the subnet mask in the Mac. None of that stuff will get pushed out to the Macs. Why? I don't know. The Dell took whichever IP number was left over. I never could get the linksys to push the IP#s, DNS, etc to the Macs or get them to acknowledge the WEP keys. If you want to allow room for other users to enter your network wirelessly just add a few extra slots to the scope, though that does present a security risk, so be careful. As usual, I think that the Apple Airport is compatible with PCs because they adhered very strictly to the 802.11x standard, but the linksys and other systems seem to have strayed a bit from the standard, so it works with PCs but not perfectly with Macs. good luck.

bwanaaa:

Yes, I agree. Forget DHCP and just go with fixed ip addresses. Or disable the high speed part of the airport extreme card- some waps dont work the switchover well.

Get rid of dhcp first though.It's more secure anyway, why allow any dhcp subscriber to join up? Also , I've got wep working. Despite all the hype, it's not that easy to crack. I've run air snort for days on end, collecting millions of packets, without a crack.

10.14.2003 at 01:47PM PDT, ID: 9550116

GroverDill:

Thanks for your comments so far. It looks like I'm going to need a bit more help filling in the blanks before I'll get this to work, though. Please bear with me. :-)

Okay, my DHCP server is set to allow 50 users, starting at 192.168.1.100 (I know this is a security issue, but I'll limit that after I get this airport thing to work. I don't want to tinker with stuff that may get me further from resolving this particular issue.) According to my clients table, connections 101-104 have been taken. Thus, I should be able to manually set the G4 to IP 192.168.1.105, right? In my system preferences->network->airport window, I manually set IP to equal 192.168.1.105, Subnet mask to equal 255.255.255.0 (which is what all my other network devices use), and the router address to 192.168.1.1.

I'm not sure what to set DNS Servers to. I tried it both blank and with my router IP, but it doesn't seem to work either way.

In any case, I still can't connect to the internet AND the connection to 192.168.1.105 does not show up in my router DHCP client table.

As for the high speed component of the airport card, I'm not sure how I'd go about disabling it. I'm definitely trying to connect to an old-school 802.11b network.

Thanks again fellas!

The user guide for this product can be downloaded at:

ftp://ftp.linksys.com/pdf/befw11s4_v2ug.pdf

This provides much more information than the quick setup guide that came with in the box, but it is about 60 pages.

If you go to a computer that is hardwired to the router and browse to 192.168.1.1 you should be able to get into the HTML router administration program. It is very intuitive, so don't be scared by it.
The first page of the set up program should allow you to choose where your router gets its IP address. This is the External IP address that is assigned by your ISP. It should say something like "obtain IP addresss automatically" or something like that. On another spot you define the internal IP# for your router, I believe the default is 192.168.1.1.
There should be a screen, I don't recall exactly what it is called because I'm doing this from memory, but it allows you to define how many clients to allow and what their scope should be. The computer that you are trying to add needs to have an IP address within that scope. According to your comments above, your computer should be covered there. The DNS numbers should come from your ISP. There should be at least 2 sets of numbers, maybe more. Perhaps you can get into the settings for the Cable modem to get this info. Without the DNS numbers, you won't be able to see the internet, but you should be able to see other computers on the network.

In summary, your ISP should push an IP address to the modem and then the router, and provide you with the DNS numbers so that you can browse the internet. Once those are set, your router then monitors a different set of numbers for the computers inside the network (either set for DHCP or static IP) and divies up the bandwidth between them. If you can get the DHCP and/or the WEP to work with the Macs I'd like to know how because I'd love to use WEP.

GroverDill:

I still haven't figured out out what the correct settings should be for my client G4, tho. Again, I've got other connections that work fine through my router, so I think everything is okay on that front. When I check the router's web based config page, it gives me info for the LAN and the WAN setups. The thing that's confusing is that I am pretty sure that the G4's ip info needs to be set based on the LAN settings of my router (since it is "behind" the router in my network setup), for instance, the 192.168.1.50. However, my router's DNS entries are listed under WAN in my router setup screen. Are these the correct values, then, to use when manually setting up an IP behind the server? It seems like they would be somehow translated by the router hardware before ending up at a LAN computer (my G4).

fhieber, could you do me a favor and check out what your wireless mac setup looks like in terms of ips and stuff, when you get a chance? On my side, I have:

IP address: <some vacant value within those declared in my router's DHCP setup>
Subnet: 255.255.255.0
Router: 192.168.1.1
DNS: <the entries listed for my routers WAN DNS servers>

and again, it still doesn't work (I can't even talk to the router's admin ip from my G4 browser).

10.14.2003 at 03:32PM PDT, ID: 9550751

fhieber:

If you give me an email address I'll send you some screen shots from the router setup and the mac set up. I'm new to the Expert Exchange, so I don't think that I can post pictures on here. I can be reached at ztirffritz@yahoo.com.

10.15.2003 at 03:04PM PDT, ID: 9558292

GroverDill:

Thanks a ton for your email fheiber. I went through my router setup and tried to make it look as close to yours as possible. The only real change I ended up making was adding the DNS entries that showed up under WAN (in setup) to the DNS fields in the DHCP window.

Unfortunately, it's still not working. I'm still not exactly sure what to set DNS as in the client (G4's) airport setup. The funny thing is, when I copy the DNS settings for the router into my G4's DNS window, I swear it's trying to do something when I try to connect to a web page (Last time it told me it could not connect to the router because it got a Posix error -60, which seems kind of intriguing).

I'm beginning to think that this problem may have me beat, I dunno. I know it's not supposed to be this hard, so maybe I have an unsurmountable hardware combination problem or something. :-(

In any case, if anybody (fheiber?) has any other thoughts on stuff I could try, I would sure appreciate it.

Maybe it would help if I took some screenshots if my setup. Can anyone tell me how to take screenshots on a Mac?

10.15.2003 at 03:32PM PDT, ID: 9558423

fhieber:

In OS X go to Applications/Utilities/Grab. This little utility gives you a few options for taking screen shots, you can even time them so that you can have a few seconds to open drop-down boxes for the screen capture.

Pre-OS X requires rental of an octupus to press all of the buttons simultaneously...just kidding. Just look up screen capture in Mac Help.

In Windows, use Ctrl+Print Screen (one of those 3 buttons above "Insert", "Home" and "Page Up" that no one ever uses anymore) to capture the entire screen. Ctrl+Alt+Print Screen gets just the active window.

Good luck!

GroverDill:

Thanks again fhieber. Here are some screen shots (full-res, lookout...) if my G4's setup. Um, if I could mention in advance, if any of you are smart enough to use this info to break into my computers, please don't. Thanks.

http://www.peasej.com/airport1.jpg
router setup screen, Airport TCP/IP settings, Airport Internet Config screen. Some things to note: in the configuration pulldown of the Airport Internet Config screen, Airport is the only option, but it disappears sometimes when I open the dialog. Also, the Network SSID "Wireless" is correct, and is automatically found by Airport. So it's seeing something...

http://www.peasej.com/airport2.jpg
router dhcp screen, router dhcp client table, Airport TCP/IP settings, Airport Internet Config screen. Some things to note: these are the DNS fields that I updated after seeing fhieber's screenshots. Also, the clients showing up in my dhcp client table are my desktop pc (jeff), a laptop pc via wireless (Phet), and the G4 hardwired to the router (blank). The IP I'm trying to set, 192.168.1.105 is conspicuously absent.

http://www.peasej.com/airport3.jpg
Here I just wanted to show you my router status screen, so you can make sure I'm not entering anything really odd in the setup.

Thanks!

fhieber:

I like the disclaimer about being smart enough to hack into your computers. Rest assurred, no one can until your router works.

The links above do not work however...they look like they are trying to direct me to something inside your network becuase the address was something like 192.168.1.140:blah blah....that is a private IP address if I'm not mistaken. It would work if I was inside your network but until we get your router working, we won't be able to hack into it, or see your pictures. I'm not a networking guru or anything like that, I just like computers. I want to learn how to set up a web site inside my network that can be viewed from outside my network. I think that it has something to do with port thingys (that is the technical term right?), but I've not figured it out yet...

10.15.2003 at 07:46PM PDT, ID: 9559139

GroverDill:

No, those are all actually on a public server. Hmm... maybe you are behind a firewall or something?

Those addresses should eventually resolve to:
http://www.jesush.com/peasej/airport1.jpg

so that might be something else to try...

10.15.2003 at 09:19PM PDT, ID: 9559480

bwanaaa:

according to those pix, you still have dhcp active. did you try disabling it?

10.16.2003 at 09:09AM PDT, ID: 9563229

fhieber:

I agree, turn off DHCP first. I had very similar problems initially. Somehow it works now, but I don't trust it yet.

10.16.2003 at 01:30PM PDT, ID: 9565273

GroverDill:

I was unenthusiastic about disabling DHCP since I thoght manually entering all the information for my various machines. Oh well...

Okay, it still doesn't work. :-)

I was able to get all my wired connections back up and running, but the G4 still won't connect to anything when I turn off the wired connection. At least this lets me know I was on the right track in terms of entering DNS info for the G4 TCP/IP client...

Some more pictures for you:

http://www.peasej.com/airport21.jpg
updated router DHCP screen, Wired TCP/IP settings, Airport Internet Config screen. This connection works...

http://www.peasej.com/airport22.jpg
updated router dhcp screen, Airport TCP/IP settings, Airport Internet Config screen. This one doesn't.

Any other ideas? :-)

Try resetting the router-unplug it, hold down the reset button while you turn on the power, continue holding the reset button until the little light blinks.

the linksys has a lot of other features that can screw up a network connection. I am not familiar with this particular product, but the consumer grade routers are often a 'little' off spec when it comes to hardware implementation. That's why some pcmcia cards dont work well with certain routers. Try disabling the 'g' hispeed wireless function. Can this be done on this router?

Also, disconnect ANY wireless phones in the house. UNPLUG THEM ALL. I had a similar problem with my 2.4 ghz phone and i moved back to a 900 mhz phone to solve similar wireless connectivity issues.

10.17.2003 at 08:10AM PDT, ID: 9572101

fhieber:

Record your settings if you try to reset the router. Pressing the reset button for I think 10 seconds resets it to factory condition. I'm not sure if it dumps the firmware updates. I doubt it, but it might.
