Guest matcho13579 Posted August 21, 2011 Report Posted August 21, 2011 Hi guyz! I'm facing a big problem now...I've got a variable IP adress on my net and my Blade cannot get an IP adress, it stucks at "Getting IP adress" and then it shows "Failed to connect" (or something like that)...where is the problem? (btw. I have a GT540 Optimus at home and it connects without any problems) sry 4 my english, hope you understand :)
Guest t0mm13b Posted August 21, 2011 Report Posted August 21, 2011 (edited) Have you added the mac address of the handset to the wifi router? It happened to me, easy to forget that the wifi router needs to be told of the mac address of the blade and allow it through if mac filtering is on. Edited August 21, 2011 by t0mm13b
Guest matcho13579 Posted August 21, 2011 Report Posted August 21, 2011 @Phoenix Silver: CM 7.1.0 RC1 @t0mm13b: how to do it?

It happened to me, easy to forget that the wifi router needs to be told of the mac address of the blade and allow it through if mac filtering is on. Just turn mac filtering off, it's the most useless invention ever. If it hangs at "Getting IP Address" then it's likely to be a problem with dhcp (dhcpcd is the client program on the blade). As you're using CM7 you should use the Cyanogenmod Issue tracker to report the bug & include a logcat of the error, then they might be able to fix it. http://android.modaco.com/index.php?app=core&module=attach§ion=attach&attach_rel_module=post&attach_id=71080 If you just want a quick temporary fix then replace /system/bin/dhcpcd with one from a rom that works ok on your network, older versions seem to be better. To get a proper fix for it the cyanogenmod team need a log file posting on their bug tracker. Edited August 21, 2011 by wbaw

Which seems to bring home a common answer that you've pointed out a while ago in relation to Wifi - and yes, it could definitely be a broken wifi router if the OP is running CM7's dhcpd. Some brands just fail - you mentioned one of them... cannot remember which - was it Netgear?

Some brands just fail - you mentioned one of them... cannot remember which - was it Netgear? BT Homehubs fail with cyanogenmod, there may be other brands too. Later versions of dhcpcd seem to have stricter controls, so if your router's dhcp server isn't quite up to spec it'll fail & refuse to connect. It's only relatively few routers that it fails with, but imo dhcpcd should be more error tolerant. Because there are only a few types of router with this type of problem, logs of it happening are very important if we ever want to see it get fixed. MAC filtering doesn't work at all, never mind work well. Most stupid invention ever. The only person it prevents from doing whatever they like with your wifi is you & other authorised users. There is a good reason that it wasn't included in official wifi specs, because it is completely ineffective. Every packet that you send to your wifi router has your MAC address sent in clear text. MAC addresses are simple to spoof (copy & paste at worst). It's probably done automatically by any wifi hacking tool & your attacker might not even notice that you're using it. MAC address filtering doesn't add anything at all to the security of your wifi. It just makes it less convenient when you want to connect a new device to your network, a hacker probably wont even notice it. If you want to stop unauthorised users of your wifi then you should set a long & hard to guess wpa2 password. Even ZD Net list it as the dumbest way to try to secure a wireless lan: http://www.zdnet.com/blog/ou/the-six-dumbest-ways-to-secure-a-wireless-lan/43 http://www.zdnet.com/blog/ou/wireless-lan-security-myths-that-wont-die/454 Edited August 21, 2011 by wbaw

My interpretation of what you're implying - with wifi mac filtering on MY wifi, it prevents me from accessing the internet etc... with blade's wifi on and prevent my blade from accessing the internet...and implying that its my fault? :blink: That is a very confusing statement to make and am trying to make head or tail of it...in fact it does not make any sense at all....
Guest wbaw Posted August 21, 2011 Report Posted August 21, 2011 (edited) I'm not implying anything, stop trying to interpret things that aren't there. Just read what I wrote, read the links I posted to back it up if you still don't believe me. There is no subtext to interpret, I wrote it as clearly as I possibly could. MAC filtering serves no useful purpose. If you use mac address filtering then every time you want to connect a new device to your network you have to add it's mac address to your router's filter. That is pointless work & it's much harder than anything that any hacker would need to do to break it. Edited August 21, 2011 by wbaw
Guest matcho13579 Posted August 21, 2011 Report Posted August 21, 2011 so, how can I turn off mac adress filtering?
Guest irishpancake Posted August 21, 2011 Report Posted August 21, 2011 (edited) so, how can I turn off mac adress filtering? Is it turned on in your router? Do you need it when you connect with your laptop? Or any other device. Optimus? If not, no need to worry. Usually not turned on by default. Edited August 21, 2011 by irishpancake

Guest irishpancake Posted August 21, 2011 Report Posted August 21, 2011 But I don't know how to check if it is turned on or not... What about the other questions. I don't think you got it... so no worries.
Guest Maxsas360 Posted August 21, 2011 Report Posted August 21, 2011 Well my neighboirs are pretty dumb. Why? I reinstall their Windows every 3 months. So I turned the security off and turned SSID broadcast off. Testing the wifi stability now
