Another possible fix for hotel wireless issues Internet
Many times I have found success using macosxhints tips for logging onto stubborn hotel wireless routers, but this weekend one had me stumped. It was a WEP encrypted network, and the front desk gave me the WEP passkey phrase. My MacBook connected to the router fine with the passkey, but the router wouldn't issue an IP address through DHCP, no matter what I tried. Here's the almost-feels-like-hacking fix I finally tried, and it worked:
  1. I opened System Preferences » Network » Airport » TCP/IP tab and set the configuration to manual. Then I set the IP address to 192.168.1.10 and the router to 192.168.1.1.
  2. I set the DNS servers to 4.2.2.1 and 4.2.2.2, separated by a return (this is a key step!)
  3. I then opened Terminal and ran ping 192.168.1.1 to see if I magically guessed the correct router. I didn't (no return ping). So, I changed my IP address to 192.168.2.10 and the router to 192.168.2.1. I tried ping again, and I got a ping back.
  4. Now, I realize that I'm messing with DHCP settings, so to be fair, I pinged 192.168.2.11, and when I didn't receive a return ping, I then changed my IP address to 192.168.2.11 in case 192.168.2.10 had already been given to another computer on the network. (I suggest continuing to ping 192.168.2.x up the line until you don't get a return ping).
After this bit of manual setting changes, I was able to fully connect to the internet.

Side note: I actually figured out that the router the hotel was using was a Linksys WRT54g. I typed 192.168.2.1 into my browser window, and the login for that router popped up. An internet search yielded many WEP issues for Macs, and the suggestion was to use a WPA key instead of a WEP key, which isn't feasible if you're on a hotel network.

silly hint.
If the network is a 192.168.255.x you have left the hotel without find it.

Better method:

1- open the terminal
2- type "sudo tcpdump -n -i en1" (en1 or whatever is your wireless card)
3- type your password
4- wait for a broadcast
5- now you have the broadcast address. So it's simple to retain both network and subnet mask
6- assign to yourself an address on that network
7- ping all host in that network (with hping o nmap -sP)
8- one of the responding host should be the gateway (usually lower or upper ones)

Bye

You have the hint here. The original is a try and retry until... Not very useful!

Best then, would be to ask the front desk on which address they use, you can try the original hint!

Thanks

your method requires nmap, which most people won't have installed.

use "ping 192.168.1.255" to find the available hosts on your subnet.

Again: there wasn't any subnet, as the router wouldn't give my mac an IP address or a router address.

darkpila, could you further explain ( give more details, step-by-step) of how to do this?

I would appreciate it, thanks.

if you have trouble logging on with a WEP pwd, try putting a $ in front of the pwd

for WEP

I had trouble connecting to a hotel network a couple months ago. I connected to the open wireless router just fine, but the only webpage that would come up in Safari was a password page to access the internet. I entered the password the front desk gave me, but it kept going back to the password page. I tried Firefox and entered the password once and the internet worked. I could then go back to Safari and use the internet just fine.

I'd wager that what you experienced was more likely a Safari caching issue -- it was showing you the cached page -- than a connection issue.

I have also run into a similar problem. I found that if I had multiple tabs open in Safari, I could not log in, but if I had only one, it would let me. Using Firefox also worked.

True, but this isn't the issue here -- I was able to get on to the hotel's router fine, but it wouldn't give me an IP address. Thanks to the poster above for the info about getting the router address.

Because of all of these incompatibility issues, not just with Macs, but with certain portable devices and what not, I gave up and decided to save myself the hassle of constantly helping out guests with their issues and run the WLAN side of my network wide open and accessible for anyone who cares to go online; with my own LAN separated and secured from outside access.

You're assuming the front desk will know what an "IP Address" is! ; )
