brgmtt Posted April 10, 2010 Share Posted April 10, 2010 Hi everyone, As the title says, I installed Leopard on my Packard Bell Easynote TJ65 (specs in signature). After a bit of effort, I managed to make everything work - except network. I didn't expect my Intel 5100AGN to work, since I had seen multiple posts saying it is not supported, so I tried with all the network interfaces I could connect to the laptop: the integrated Broadcom BCM5784M, a Belkin USB wireless adapter with Ralink RT2571WF chipset and another wireless adapter, from Dikom, with Zydas ZD1211B chipset. Both wireless adapters, after installing appropriate drivers, give the same problem: in System Preferences>Network, they have a yellow status symbol and there is a message saying that they have a self-assigned IP address and thus won't be able to access internet. Though, the IP is correct and I can even access the wireless router without any problem, and the router is able to see the computer. Both adapters work on my other computer with Leopard. As for the integrated ethernet controller, I found a kext for BCM5787M, which was modified and should work with my 5784, having the only problem that it works just in promiscous mode (I have to run "sudo tcpdump -i en0" to make it work). When doing so, in network preferences, the interface has a green symbol and says it's connected. The IP is fine. Since this time I was connecting directly to the modem without passing through the router, I created a PPPoE service, which too said it could connect without problems, also the bars of "Sent" and "Received" packets show activity. But the result is the same as before: I can access the modem, but not the Internet. Any ideas to what I could do to make things work?

motomotomd Posted April 13, 2010 Share Posted April 13, 2010 Have you tried setting the DNS servers manually in the Network Config, if your not sure what your ISP's DNS is, try using open DNS. 208.67.220.220, 208.67.222.222 Could well be that your DNS isn't being picked up from the Router automatically.

brgmtt Posted April 15, 2010 Author Share Posted April 15, 2010 Thanks for answering ^^ Nope - same result. BTW, it was picking the right DNS servers, the same it picked under Windows... Other ideas?

motomotomd Posted April 16, 2010 Share Posted April 16, 2010 Thanks for answering ^^Nope - same result. BTW, it was picking the right DNS servers, the same it picked under Windows... Other ideas? Try pinging or tracerooting the addresses your after, see where the requests stop. Wouldn't have thought it was a driver issue as TCP/IP seems to be working if you can access your router.

brgmtt Posted April 17, 2010 Author Share Posted April 17, 2010 Well... Something strange seems to be going on... I pinged 87.124.84.6 (insanelymac's IP) and it worked... At least, it said it received all the packets transmitted. But, both with Safari and Firefox, trying to open 87.124.84.6 results in an error message saying it had been impossible to contact the server "insanelymac.com"... o.O Link to comment https://www.insanelymac.com/forum/topic/215246-solved-snow-leopard-can-access-router-but-not-internet/#findComment-1450506 Share on other sites More sharing options...

motomotomd Posted April 21, 2010 Share Posted April 21, 2010 So? No ideas... can only assume that it is something driver related then in this instance.

brgmtt Posted April 23, 2010 Author Share Posted April 23, 2010 Well, thanks anyway ^^ News: I tried to connect to an "Original" Mac... The other Mac could access mine perfectly, file sharing and all that stuff, but, if I tried to access the other mac with mine I was told me it could not contact the other computer... Also, I tried following acero's instructions in this topic, but the results were the same. I think it may not be a driver issue, since it happens also with the wireless adapters... After this, though, when I was trying to access the IP I use to test the connection (insanelymac's one, 87.124.84.6), I accidentally entered 87.124.84.73 and, well, that page loaded! So, I thought there was hope, and I entered Google's IP (209.85.129.105) and it also loaded... But, when I tried to search something, it said it could not access the server. Though, changing the "www.google.com" in the search results page url with 209.85.129.105, it worked... If it acted like this with all websites I would think it were a DNS issue, but some IPs (like insanelymac's one) don't work at all, while pinging them works... I'm really frustrated I noticed this behaviour after following acero's instructions, but maybe it was this way also before... I don't know, as I said, this was almost like a serendipity...

brgmtt Posted April 27, 2010 Author Share Posted April 27, 2010 Err... What should I do with that? xD The IP of DNS Server is fine, it's the same I get under Windows... I was desperate so I used Gparted and gptsync to reduce my Windows partition and install another copy of Snow Leopard, using the retail DVD (previously I had used SnowOSX Universal 10.6.2), and, after installing the driver the wireless adapter worked, I mean, I could browse. So, I thought I might be SnowOSX's fault, adn deleted the new partition and restored things as they were before (1 partition Mac, 1 partition Windows), before installing OSX again using the retail DVD. Though, this time I could not browse... I am really puzzled...

acero Posted April 29, 2010 Share Posted April 29, 2010 hi take a look ... http://www.askdavetaylor.com/find_the_dns_...n_your_mac.html hi try also this .take a look at the Mac firewall logs then deleted the firewall configuration file (located at /Library/Preferences/com.apple.alf.plist) and configured the firewall to temporarily allow all connections, and then back to allowing essential services. this is a copy from an apple blog,even macbook pro have this dhcp self assigned ip problem. update : sudo killall mDNSResponder "sudo killall -USR1 mDNSResponder" to enable operation logging. "sudo killall -USR2 mDNSResponder" to enable packet logging. "sudo killall -HUP mDNSResponder" to clear the DNS cache. "sudo killall -INFO mDNSResponder" to dump mDNSRepsonder's internal state. For reference in Snow Leopard the DNS cache is now stored by mDNSResponder and in order to clear it you need to restart the process using sudo killall -HUP mDNSResponder. You can get more info (logging, dump internal state, etc.) by using different flags to the killall command.

brgmtt Posted April 29, 2010 Author Share Posted April 29, 2010 I looked in the log, there were only some lines with "_CFGetHostUUIDString: unable to determine UUID for host. Error: 35"... Also deleted the configuration file, so it allowes any connection, but nothing changed at all. I noticed that before upgrading to 10.6.3 internet worked; though I have to update because otherwise my graphics card won't work.
