3/15    Apparently the firware in my netgear MA401RA pcmcia card has
        broken WEP support. Any recommendations for an 802.11b
        card that fully works with linux? Any of the 3com Xjack ones?
        \_ I'm not sure if there's a difference but the MA401 is prism2
           based, here, setup info
           http://www.eecs.umich.edu/~chhabra/netgearwireless.html
           prism2/2.5/3 firmwares listed at http://www.red-bean.com/~proski/firmware
           failing that, I'm using a USR2410 (also prism2 based).  Any
           prism2 or orinoco should work just fine. (rebadged dells, etc)
           \_ some versions of the prism2 firmware look to be broken.
                \_ hence the link to the collection of firmwares.
                   1.07.01 for me. (secondary, 0.3.0 or something like that
                   for primary) -dwc

4/19    After installing Logitech wireless mouse, my friend cannot connect from
        his PC to his wireless broadband router via a USB wireless network
        device.  It said that it cannot obtain IP address from the router.  Even
        uninstalling the Logitech wireless mouse doesn't help.  Do you know how
        to fix the wireless LAN problem, so that his PC can obtain IP address
        again?

5/23    I have DSL through AT&T. The service was originally established
        through PacBell, transitioned to SBC, and now AT&T. I still have
        my original plan and never converted to a SBC Yahoo! (now AT&T
        Yahoo!) account. I noticed the price will be a lot cheaper if I
        do. Are there any drawbacks? I thought someone mentioned some
        negatives about the Yahoo! tie-in once upon a time.

2/18    My DSL modem's ip address is 192.168.0.1, my internal network
        behind my router is 10.0.0.x. Is there a way I can configure
        the router so I can access the DSL modem from my 10.0.0.x
        network directly without re-wiring? Static routes? I tried it
        but no much luck. I also tried changing my internal network to
        192.168.0.x, but still does not work. Thanks.

1/28    Just switched to Comcast from SBC and generally happy with it.  But
        can someone please explain to me why they are constantly pumping
        ARP traffic through the network?  It seems harmless, but I'm curious
        as I didn't see it with DSL.  It's a little disconcerting to see
        constant traffic on your router, even if ARPs are harmless from
        a bandwidth perspective, and it makes the WAN send/receive light

1/21    I am trying to setup a small network for my girlfriend's
        mom's company.  They just bought an accounting package
        which requires windows 2003 server.  And they want internet
        access from each computer.  How should the network be setuped?
        Would it be dumb to use static IP for each computer and a
        computer as internet gateway?

8/29    What's the difference between a hub, a switch and a router?  Thx.
        \_ AFAIK, probably be corrected by someone:
           hub: Allows communication on a LAN with bandwith shared amongs all
                the nodes on the hub and maxing out at the max line speed.
           switch: Allows communication on a LAN with bandwith greater than
                the max line speed (point to point)

6/2     I've been to many places and almost every place I go to have
        802.11b/g. However, almost all of them have protected access,
        which I presume they use because they don't want people stealing
        their bandwidth. So here is one idea I think will really
        revolutionize 802.11X... an option in the router that allows you to
        specify the percentage of unprotected bandwidth you are willing to

2/25    What is the smallest (physical and price) cisco router that can
        handle BGP?  It should be able to have more than 256 ram.
        \_ When you say ``handle BGP'', do you mean supports the bgp
           protocol or supports enough ram to keep a reasonable (what do you
           consider to be reasonable) number of routes in memory?  Do you want
           to be peering at PAIX, or do you just need a router to run the T1

It was still painful enough for me to create this resource for anyone wandering down this road, as well as for myself for future reference as a snapshot of a working configuration. Even though the usually suggested Linux driver - orinoco_cs, has been reportedly hacked to support Prism based cards as well, it has not exactly received rave reviews. Virtually every source I came across, suggests the use of hostap drivers. You might want to grab the latest distribution from the hostap website . There is some ambiguity in the available documentation, which touts the fact that it can be used to set up an Access Point, without making it crystal clear that it is possible to use it in pure client mode as well. It might appear trivial in hindsight, but things are a little different when you are new to wireless networking and buggy documentation does not lay emphasis where it must. Further, for the record, this wireless card is a PCMCIA card, and will use make pccard and not make pci, as many places I found, claim. I will not pretend to give instructions for setting up an Access Point, as : I do not possess one, and; I have no experience in setting up wireless access points or routers. One day, that will change, and then I will post full details of that part as well. And before you begin following my advice, Read The Standard Disclaimer RTSD ? Optional Mohit Muthannas Quickswitch, in case you are switching between network profiles. I do not include instructions for that here, but that could change if enough number of people press me to do that. As it stands, the sample configuration profile that comes with Quickswitch is self-documenting. Do not enable any included drivers this may change if the kernel folks decide to include support for hostap, or a reliable hostap kernel patch becomes available. In case you intend to use Ciscos VPN client for securing your wireless connection, enable modular support for iptables NAT and ESP, do what follows and look into the procedure at the end of this document. Restart your machine so that the compiled kernel becomes the running kernel. Now make sure that wireless tools and XForms library are properly installed. Now compile the hostap drivers : make hostap make pccard make install_pccard .

I did contribute to it since 1999 thanks to Hewlett Packard sponsoring my work. My main contribution was the Wireless Extensions support of course, multi-firmware support and a few bug fixes. The Wavelan IEEE/Orinoco is the current generation of Wireless LAN hardware offered by Lucent and others. This page describe the state of the new Linux MPL/GPL driver for this hardware. There are three drivers supporting the same Wavelan IEEE hardware. The last one is based on a binary library and supported by Lucent, called wavelan2_cs . For all problem related to wavelan2_cs, please contact Lucent directly. On the other hand, this page deals exclusively with orinoco_cs , the new MPL/GPL driver, now part of the kernel 24 Various people outside Lucent are active keeping this driver alive. We are in the process of phasing out gradually wvlan_cs in favor of orinoco_cs , which has all the features of the former without the bugs. We are recommending people doing a new installation to start directly with orinoco_cs . Some people strongly beleive in the concept of Free Software and Open Source, especially when it come to stuff that reside in kernel space. Can be made to work on PPC, Alpha, StrongArm, ia64 and your favourite platform doesnt mean that it will work out of the box. For PrismII, there are the famous linux-wlan-ng and HostAP drivers, which have advantages over this driver. Because Orinoco support all those hardware, people think they are the same hardware. However, all those other drivers support only one of these hardware, and only the Orinoco driver support all three of them . At boot, the Orinoco driver will print in the message logs which of the three hardware it has detected, with the firmware version number. These are other hardware that people often confuse with the Wavelan IEEE/Orinoco, but which are totally different and incompatible : The Wavelan was a non IEEE compliant hardware that Lucent made before the Wavelan IEEE/Orinoco. Patches for orinoco_cs and various web pages related to orinoco_cs Other people are hacking like crazy on the driver : David Gibson is the author and maintainer of the Orinoco Linux driver. David has set up a SourceForge Project for the driver, that mostly contains a Mailing List . Manuel Estrada Sainz maintains the Orinoco-USB version of the Orinoco driver. Andreas Neuhaus was the original maintainer of the Wavelan IEEE Linux driver wvlan_cs. Harald Roelle did the original PPC specific patch now outdated and has a page on how to set up a Wavelan IEEE under Linux-PPC and how to connect it to the UFO the Apple Airport base station . Anton Blanchard is the did some work on the the Wavelan IEEE Linux driver wvlan_cs, including PPC support. Benjamin Herrenschmidt has modified the Wavelan IEEE driver to make it work with the Apple Airport card . Ian Goldberg has a pretty complete web page on how to set up the Symbol CF card on the Sharp Zaurus . Brad Allison has a page to workaround some Red-Hat 72 quirks with orinoco_cs , and how to use Red-Hat 73 specific wireless configuration . Martin Pot has a page on how to set up the Orinoco driver with Red-Hat 73 with many quirks and build a Wireless Router . Paul Lucas has a page on how to set up a Wavelan IEEE under Linux-PPC with an updated PPC specific patch. Rich Bowen and Dino Lachiusa explain how to setup a Wavelan IEEE card with the RG-1000 . Mad Science Research labs explain you how to upgrade the Airport UFO to RC4 128 bits this should apply to the RG-1000 as well. Constantin Von Wentzel explain you how to put an external antenna on the Airport UFO this should apply to the RG-1000 as well. Langston has written some Perl script to check the status of the Airport Base Station . Meinlschmidt has developped an impressive package allowing to monitor a Wavelan Access Point using SNMP. Greg Hankins is porting the above software to work with RoamAbout Access Points . From experience, 95 of the problem are not due to the driver but a generic Pcmcia configuration issues . Make sure that your Pcmcia socket and setup is functional, and try another Pcmcia card before blaming the driver. Lucent Firmware revisions : The latest driver should work across all firmware revisions, it has been tested with 116, 408, 452, 604, 606, 616 and 728. However, some feature might not work well in all firmwares promiscuous in 604 or are even not available at all fragmentation for 6X, Microwave Oven for 4X. It seems that with firmware 752 the power management setting is ineffective. Lucent Firmware updater : available on Lucent web site , not available for Linux. Note that most firmware updaters require a specific version of the Windows driver to work always messy for me. USB adapters : for Lucent/Agere, use the Orinoco-USB driver, for PrismII adapters, use linux-wlan-ng. MiniPCI cards : there is various kind of MiniPCI cards in various laptops. Some are based on a PCI-Pcmcia bridge Dell - confirmed working, some are based on a USB adapter HP - working with Orinoco-USB and some are based on a PCI Prism25 card IBM/HP - confirmed working. Better than in Windows, because both IP config and Wireless config are changed synchronously. This may be also achieved using the specific networking scripts of some distributions . Multi-card : The driver supports it 2 cards in a box and it has been tested successfully. SMP : The driver is fully SMP safe and has been successfully tested on a SMP box, including Wireless Extensions. Configuration : The only way to configure the orinoco_cs driver is through the Wireless Extensions , using the wireless init files . Those two Ad-Hoc mode are totally incompatible and do not interoperate between each other. For Orinoco cards, IBSS Ad-Hoc mode is available only in firmware 606 and later. For Symbol card, IBSS Ad-Hoc mode is available only in firmware 200 and later. For PrismII cards, IBSS Ad-Hoc mode is available only in firmware 008 and later. Debugging Ad-Hoc mode : the field Access Point or Cell shown by iwconfig is usefull for knowing whats happening. It should be the MAC address of the first node started and all nodes should have the same value apart if they are out of range. Encryption keys : Encryption setting is fully functional and available in the wireless init files . Fragmentation setting : firmware 6X and later removed direct fragmentation threshold setting in favor of microwave oven robustness automatic fragmentation. For those firmware, the fragmentation setting in the driver enable or disable MWO robustness. Signal strength in ad-hoc mode : set a MAC address in the spy list using iwspy , first address in the list will appear in /proc/net/wireless as well as with iwspy. Promiscuous mode : does work with firmware 4X and open network no encryption. Older driver would not work with specific Access Points Linksys, and in theory, the latest driver works around those gotchas. If you can receive but not transmit with your Access Point, try playing with the use_old_encaps module option. Short preamble : The Orinoco cards dont support short preamble, so you need to disable it in your Access Point. The Symbol cards support short preamble, and this may be enabled via iwpriv ethX set_preamble 1 . Symbol and Ad-Hoc interoperability : Because Symbol card enable short preamble by default, you may have interoperability problem in Ad-Hoc mode with other vendors, so just do iwpriv ethX set_preamble 0 you may also set that in the wireless init files using IWPRIVset_preamble 0 .
