Barry is using an alternative firmware loading and associated module loading regime in 4.1. Apparently this has a bug in the startup script, so firmware will sometimes fail to load during boot up. Obviously this will be fixed in the next alpha or beta, but the solution in the meantime is to unload/reload the module, thus -
Of more significant concern; Puppy 4.1 uses the new mac80211 wifi stack, and it seems that there are some "teething" problems with this new system. Forum member fleamour reports that the p54pci module can establish an unencrypted wifi connection under 4.1alpha2, but fails with WEP encryption - http://www.murga-linux.com/puppy/viewtopic.php?t=29313 If anyone has a successful WEP or WPA connection under 4.1alpha2 could you please post your "lsmod" output here. |

tempestuous, as this new wifi stuff is under heavy development and still immature, I wonder if there are any significant improvements with the 2.6.26 kernel? _________________ http://bkhome.org/blog2/ |

I am posting this using puppy 4.1 alpha2 with a WPA2 network connection. Here is the lsmod output:
This is what wpa_cli status outputs:
I thought wpa_cli status would help. I hope this helps, tempestuous I do have the bug where network wizard says it can not connect to wpa, then wireless test executes and says connection made. _________________ Enjoy life, Just Greg Live Well, Laugh Often, Love Much |

Thanks JustGreg. I see that the aes_generic module is loaded, which is what I would expect for WPA encryption, but I thought that the crc32c module would also be required? But it seems that encryption is still a problem with certain drivers. On the Developer Blog, 14 Jun 2008:
So to help troubleshoot the wifi encryption problems that various forum members are experiencing in 4.1alpha2 I have compiled these latest wifi drivers for the 2.6.25.4 kernel, now attached. BIG FAT WARNING: These new drivers are for temporary testing until Puppy4.1alpha3 is released. After installing this dotpet, unload the wifi driver in question plus all modules it depends on, because these will be the original modules which still exist in RAM. Now reload your wifi driver, which now will be the new version. Once you reboot, the whole process needs to be done again, because Puppy4.1alpha2 apparently restores some of its original modules from the initrd.

Barry, I got these updated wifi drivers from - http://linuxwireless.org/download/compat-wireless-2.6/ The souce code is called "compat-wireless-<date>.tar.bz2". This source code includes both new mac80211 and old ieee80211 subsystems, plus all standard wifi device modules. But one module which is missing is the ieee80211softmac, which is important for the old bcm43xx wifi module. There are some interesting extras in the source code; there is a script which handles the choice between the conflicting bcm43xx and b43legacy modules, and a similar script to choose between ath5k and ath_pci modules. Soon into the compilation I saw this warning -
I looked at menuconfig to read the Help information. I don't understand the importance of these 2 settings, so I'm just passing this information on so you may consider it during the kernel configuration for the new 2.6.25.6 kernel. In menuconfig "CONFIG_NETDEVICES_MULTIQUEUE" is found at: Device Drivers > Network device support > Netdevice multiple hardware queue support and "CONFIG_NET_SCHED" is found at: Networking > Networking options > QoS and/or fair queueing |

Oops, it appears that since Puppy (4.1alpha2) now restores its modules at each bootup from the initrd (??) it's difficult to overwrite the original modules with new versions. If anyone can think of a way around this problem, please advise - because it's quite feasible in the future that people will want to install revised/modified modules. |

No, 4.1alpha2 does not do that. The modules are all in pup_402.sfs. A small selection are in the initial ramdisk, and are moved to /lib/modules/2.6.25.4/initrd before the switch_root. The original reasons for keeping a separate zdrv have somewhat disappeared. It was mostly when I was trying to shave off size of the pup_xxx.sfs to get it to loading into RAM on a 128MB system. But now Puppy is too big for that anyway, so pup_xxx.sfs is not loaded into RAM on a 128MB system. Puppy can be built with all the modules in the initrd, which will then have the problem that you have stated, which is one reason I have gone away from that idea. Puppy can be built with a zdrv, but now I have it loading on the '/' unionfs layers before switch_root, so that is also ok for installng modules. I'm only planning to release 4.1 puppies built with all modules in the pup_xxx.sfs, or a separate zdrv, so you won't have any problem with installing custom modules. _________________ http://bkhome.org/blog2/ |

Thanks for clearing that up. I'm trying to help some forum members by "remote control" and I'm having to guess what's going wrong, without being able to test myself. I now have a suspicion that these new wifi modules may be failing to load the modules they depend on. |

I tried the new modules, specifically rt73usb. It failed to load properly. After removing the pet, the wifi did not work. I had to delete the save file and restart. Wifi work fine with a new save file. Here are the modules used and what dmesg reported: Here is the order of the WIFI modules installed: cfg80211 mac80211 crc_itu_t input_polldev rfkill rt2x00lib rt2x00usb rt73usb Notified of error with

JustGreg, the upgraded wifi modules (for Puppy4.1alpha2) fail to load the other modules they depend on. The solution, as confirmed by forum member ohyes, is to unload/reload all modules in the correct sequence. In your case this would be -

Tried again per tempestuous's instructions. It worked fine on the Classmate (first generation) and connected without problem to my WIFI WPA2 network. Later in the week, I will try with wpa, wep, and open encryption and report the results. _________________ Enjoy life, Just Greg Live Well, Laugh Often, Love Much |

I'll try this as this is the first version of Puppy that does not load the wireless drivers properly. I even tried the rmmod/modprobe to no avail but I didn't try removing all related modules and reloading them. I'm using a bcm43xx _________________ http://rarsa.blogspot.com Covering my eclectic thoughts http://www.kwlug.org/blog/48 Covering my Linux How-to |

With the 2.6.25.x kernel the bcm43xx module is deprecated in favour of the new b43 and b43legacy modules. Try those. |

I have tried the wizard for wireless connection, but no love. I have read quite a bit, but am quite confused as to where to start. Wireless from the command line? Or? If y'all would be so kind, could you first clear up some puppy 4 nomenclature, please. I see that this dot pet is only for puppy 4.1alpha2. Is that the same as puppy 402? I am reasonably sure that that is what I am using. Conky shows linux 2.6.25.4 on i686. So, have I given you enough information to answer the question, or is there more needed? I also saw where some members were asked to run certain inputs in a terminal and post the results. I would be extremely willing to do whatever you say to get you the information we need to get this going. If you could please list what I should run in the console and look up in files, etc, so that you can help me it would be greatly appreciated. Puppy network wizard said Eth0 is wireless ipw2200 pci intel PRO/Wireless 2200/2915 net driver. I am using a Linksys wrt54g v2 wireless router with wpa2 and have changed to a broadcasted ssid. I am pretty sure the wrt54g v2 has a Broadcom BCM4712 chip. I have been and am using the linksys to hookup 3 wired and one wireless windoze boxes so they can get to the internet via my hughes net satellite isp. The computer is an Acer TravelMate 8100, a couple of years old. Thanks in advance, Chris. |

The wifi modules from the 2.6.25.4 kernel have problems, especially with encryption. You would be best to wait for the next release, which will probably have the 2.6.25.10 kernel. |
