Unable to connect to wifi in some hotels (self-assigned IP address)

I normally have no problem connecting to wifi, but in some hotels I am unable to connect and get a self-assigned IP address 169...


Having looked around the forums, in my current hotel I have tried several fixes without success (many of these probably apply to a permanent rather than intermittant problem):


- I renewed the DHCP lease

- I tried a manual IP address

- I created a new network location

- I deleted com.apple.airport.preferences

- I turned off the firewall

- I repaired disk permissions


Has anyone else found a fix to problems with some hotel wifi systems?


I can connect with my iPhone, but not my MacBook, so I am now in an internet cafe (and I don't think that you can "tether" an iPhone connected by wifi to a MacBook?).

MacBook Pro 2.66GHz 15, Mac OS X (10.6.7), iPhone 3G

It's DEFINITELY a MacBook Pro wireless issue. I have to travel with a Mac and a PC, and the only times I have WiFi connectivity issues are when using the Mac. And I also have often been able to work around the issue by switching to Chrome, which seems to see the WiFi home pages that Safari won't recognize....then getting online and switching back to Safari. This happens most frequently at hotels, at Starbucks and on planes when held hostage to the horrifically slow and expensive Gogo. But even trying Chrome won't work all the time, so I'm forced to get online with my iPhone first and use the personal hotspot for my computer (only b/c I have an unlimited data plan).

I have finally found a solution!


I copied the IP address that the hotel had assigned to my iPhone (in the 192.168.0.xx series) into the TCP settings for the hotel network on my Mac, and then managed to get a connection 🙂 (but only by using "DHCP with manual address", rather than "Manually").


But this seems to have killed the wifi connection on my iPhone: whatever I do I now get a self-assigned IP address 169... on the iPhone 😟 (there is no "DHCP with manual address" setting), so as I am in Paris I hope the Mac connection continues to work!


The general solution seems to be to use a static IP address, but in the "DHCP with manual address", which I had not tried before.

It is always with the hotel. If you don't believe me, get an ethernet cable and hook that up. Hotel networks are not cut and dry working or not working. I'm surprised your iPhone connected. Perhaps it connected earlier. Then the 4 kids on your floor fired up their P2P software. Nobody new will connect to the network until they leave.

That's not really a solution. You've just hacked your TCP/IP settings to bypass the hotel's DHCP server that has crashed or been overwhelmed.


Hotels are notoriously unreliable for internet. They don't have any better connection that you do at home on your cable modem or DSL - they just share it with a few hundred more people. Just checking e-mail can be a challenge.


If you are traveling and need reliable connectivity, get yourself a 3G device. You can get devices that can share the signal over wifi with a number of your own devices.

I don't agree that the "the hotel's DHCP server has crashed or been overwhelmed". I was unable to connect even at offpeak times, and have had the same experience before. It is a problem with the Mac software that other people have experienced. (When you get a self-assigned IP address, the wifi icon includes a "!".)


When travelling nationally a 3G device is a very good solution (even better my UK account for the iPhone includes tethering, so I can use that to connect my Mac to the internet in the UK).


Unfortunately when travelling to other countries, data roaming costs are prohibitive, so the 3G solution is not economic in that situation.


As I have said before, I am not the only one who has been consistently unable to connect a Mac to some wifi networks when other devices are able consistently able to connect.

I don't dispute that. I'm just saying there is no "magic bullet" to get it to work. I have hacked up my DHCP too a couple of times. There is virtually an infinite number of routers in the world, all with levels of system health. There is no way you will be able to connect to all of them. There are a number that use hardware and software combinations that are particularly unfriendly to Macs.


If it doesn't work, try ethernet. If that doesn't work, try to get the router rebooted. If that doesn't work, and you don't have your own 3G device, you just have to go elsewhere. If you can't get it to connect in a minute or two, you won't ever get it connected so don't waste your time.

I did waste a lot of time till I found this solution!


What would be useful to people who are unable to connect in a hotel is a list of simple things to try. I have suggested one (use "DHCP with manual address"). You have suggest another (get the hotel to reboot their system). Maybe there are other solutions that people have found to work?
