So, if the Proxim Orinoco card doesn't have a big square antenna and do support As usual for Lucent, the documentation and website are rich. As with all IEEE This seems exhaustive, but is mandatory for IEEE Different version of the card include different level of security bronze is basic, silver is with WEP RC bits and gold is with proprietary bit encryption.
However, the initial firmware for those cards did support only a non-compliant Ad-Hoc mode called Ad-Hoc demo mode - which interoperate with most PrismII cards. In order to gain WiFi compliance, Lucent added in recent firmware 6.
Of course, the two Ad-Hoc modes are not interoperable. The 2. Later, Lucent introduced the second generation of the Wavelan IEEE, still based on the same Hermes chipset, which is much cheaper and fully compliant with the new From firmware 1. Firmware 6. Agere has recently released a new HermesII chipset, derived from the venerable Hermes chipset. The chip interface and firmware is not compatible with the old Hermes chipset, requiring specific driver support for HermesII.
To my knowledge, this chipset is only used in the Proxim X cards. The driver is based on Lucent source code, which is a cut down version of their full driver. So, it lacks all the part about handling natively Andreas has done a very good job into providing features like Wireless Extensions I must admit that I did help him quite a bit ;- and many configuration parameters station name, channel, mtu size.
The new version adds Power management and encryption setting, change of the operating mode via Wireless Extensions, promiscuous and multicast support Andreas has done a lot of debugging of the driver and it seems now much more stable. The latest version of the driver fixes SMP support, multi-cards configuration, improve wireless. Harald Roelle has developped a patch for this driver in order to fully support the PPC architecture.
This patch mostly contain some bit order fixes. This patch should help other architecture with endianess issues. His patch was eventually integrated with major changes by David Hinds in version 1.
I added firmware detection support in 1. Nowadays, Anton Blanchard is the official maintainer of the driver, with the help of David Gibson. David has done a complete rewrite of the driver see section 3. Moustafa has released a version of this driver with scanning support. Note that Lucent has also released a binary library driver see section 3.
Non implemented : Does not support HermesII. Bugs : WEP not functional on old Prism2 firmwares, some older driver versions don't handle properly some Symbol cards. This driver attempt to support all those devices, which are described in details in their own sections.
However, even though those devices use the same MAC controller and the same driver, those devices are not the same. Each vendor has its own firmware , so the set of features of those cards vary. Some differences are visible to the user for example bits key support , some are more related to performance and robustness tuning of the MAC. Moreover, those devices don't use the same radio modem mostly Lucent or Intersil and same antennas. For PrismII cards, even the actual layout of the radio components on the card can make a huge difference.
This will mostly translate into difference of coverage between the various cards range and resistance to interference. The range between some cards may vary by a factor 2 in some conditions. The HCF the low level library provided by Lucent hadn't been maintained since the initial release of the driver and was quite difficult to read and understand. Rather than put up with that, David looked deeply in the low level of the wlan-ng driver from Mark see section 3.
In the process, David added support for PrismII cards. Then, I fixed a few Wireless Extensions bugs, added some support for Symbol cards, and we pushed the driver in the kernel. Later on, David Hinds backported this driver to the Pcmcia package for users of earlier kernels. The driver support all the firmwares and features of those cards properly and fully Ad-Hoc demo mode, IBSS mode, bit-rate, encryption keys Ben has added Airport support to this driver see section 3. Starting in release v0.
Bit rate, mode of operation managed, ad-hoc IBSS and ad-hoc demo , encryption and power management are fully working. The release v0. On firmware 2. Version of the driver from v0. Symbol CF cards are very different and supported in their own driver see section 3. The support of PrismII cards and clones is in progress.
More debugging and testing need to be done, but the driver can set most features to some degree Ad-Hoc demo mode, IBSS mode, bit-rate, encryption keys have been seen to work. It seems the upgrading firmware fixes problems related to encryption. However, the wlan-ng and HostAP drivers still have more features and are more tested Those adapters are not real Pcmcia adapters and the card looks to the system like a PCI card.
The standard driver does not support the various USB versions of the cards. The latest version v0. Pavel has integrated in v0. Pavel also fixed support for kernel 2. X, dramatically improved Symbol firmware support and fixed a tons of bugs in v0.
Version 0. This brought all the features and bugfix above in the kernel. Since then, Pavel is continuing to fix and update the driver, pushing those changes into recent kernels, but he is no longer using version number so I guess we are still at 0.
Support HermesII cards v7. WPA support. Non implemented : Do not support all firmware releases Bugs :? Not only they have released some source code to allow the source driver mentioned above, but they have as well contracted Dean to release a driver based on a binary library. Dean has written the code interfacing between Linux and the library, and has put together a nice package easy to install and with documentation.
As expected, the binary driver is probably more stable and than the full source driver mentioned above, with a slightly different set of feature, and offers all the features of Lucent Window drivers, plus a nice integration with Linux.
This driver supports both the basic version of the card and the "turbo". The major drawback is the binary core, preventing the use on other architectures PPC, Arm Now, the driver is supported by Lucent, and they keep adding in it the same features they add to the Windows drivers such as microwave oven robustness. The latest version adds support for 2. Recently, Agere has released a new version of this driver which is fully Open Source.
This new version has support for the HermesII chipset found in the Proxim Orinoco X cards but it seems it no longer support the old Orinoco cards - use the older driver version. It has also improved Wireless Extension support. Agere is still working hard on the driver and has recently added support for Wireless Scanning and WPA. Such a setup of course brings some performance degradation due to USB high latency.
The Orinoco card inside the device has the same exact features as other Orinoco Pcmcia cards and is Lucent, Agere and Proxim are directly selling this Orinoco device.
Other vendors such as Melco are also selling this hardware. One of the particularity of this hardware is that the USB-Pcmcia bridge doesn't contain a firmware, so the driver need to upload the firmware at power up.
Note that most USB Because it is based on the Orinoco driver see section 3. The big difference with the standard Orinoco driver is firmware uploading. You will need to extract the firmware for the USB-Pcmcia bridge from the Windows driver using the tools provided on the driver web page. The firmware uploading support in Linux needed for this driver is currently being finalised, so check the latest driver documentation.
On the other hand, the driver offer no support for updating the firmware in the Pcmcia card. This driver was merged into the CVS of the Orinoco driver see section 3. However, because the Orinoco maintainers are not happy with the locking strategy of this driver, this driver was never included in any release of the Orinoco driver and is not included in the kernel. The latest version of the driver may be found in the Orinoco CVS see section 3.
Interoperability : All Airport hardware is Note that this interface is not Pcmcia compatible even is the connector is the same, so this card can't be used in the normal PC-Card slot of other laptops. This is why this card work only in specific Apple hardware slot and only with a specific driver.
The Access Point the famous flying saucer is similar in functionality to the Lucent RG Residential Gateway, and is fully interoperable with other He has basically integrated the specific PPC patch of Harald Roelle , thrown away all the Pcmcia code and replaced it with the specific Apple initialisation code.
Apart from that, the driver is basically the same, with the same features and same bug ;- The second version of the driver was also done by Benjamin Herrenschmidt and is just a wrapper on top of the driver of David Gibson see section 3.
This is a much cleaner solution, because both driver share the same source, so the feature set is identical and all improvements and bug fixes of the Orinoco driver are automatically in the Airport driver and vice-versa. For example, this driver gained both Scanning and Monitor mode support in version 0. Non implemented :? Bugs :?
Intersil offer this chipset and some reference design to various OEM, allowing them to build various I expect that all the people that were formerly using the PrismI chipset will switch sooner or later to the PrismII. The rule of thumb is that if your card is not listed in another section of the Howto, it could be a PrismII card or not, see below.
In fact, so many vendors seem to be moving away from the PrismII chipset usually without warning and without changing the model name and there is so many changes happening that it's impossible to keep track of who is using what.
Please note that everything that looks like a PrismII card may not be a PrismII card, and many people are quite confused about that. Other vendors, such as Lucent see section 3. Most PrismII vendors offer regular Pcmcia cards for laptops. Some vendors also offer USB adapters beware, some of them are Amtel cards, and all of them have performance issues.
The main differences between the PrismI and PrismII chipset are a higher integration, a higher performance modem and the replacement of the AMD controller with Intersil own design. The higher integration 5 chips instead of 8 allows to reduce the price and the size of the product, and to simplify the integration. The new physical layer modem has a better performance but a lower transmit power , increasing range, speed and battery life, and is fully compliant with the Finally, the new MAC controller handle most of the The Prism2.
With respect to the driver, these 3 chipset look the same, and therefore driver supporting PrismII hardware will also support Prism2. Note that the PrismII firmwares are usually not of the highest quality and quite inconsistent from one release to another, both on the cards and on the Access Points, and you may have to try a few of them before finding the one that work for you. For example, encryption and IBSS ad-hoc mode seems to be working only in the latest firmwares 0.
It also usually takes a bit of time to get the workaround for the latest firmwares in the various Linux drivers. Latest firmware seem to have fixed most problems and have added the feature missing from earlier firmwares. A few words about Ad-Hoc modes : like for Orinoco card, the firmware support two ad-hoc mode, the Ad-Hoc demo mode not In fact, Intersil did partner with Mark to get this driver written for us!
As usual with Mark , the driver is really complete and well written. It is currently only in beta stage, and Mark told me that he needs to add more documentation and debug some more features. The driver support both Pcmcia and PCI cards. This driver is compatible with Linux bridging software, includes a generic The driver also come with a configuration tools, an utility to dump The release 0.
Note that the driver supports only IBSS ad-hoc mode 0. The PLX card allow to add a Pcmcia card in a PCI slot, but does not support any of the Pcmcia functionality, so is not supported through the Pcmcia package but directly by the driver.
Reyk has developped a patch that adds basic Wireless Extension support to the driver, and that was included in version 0. He needs help for testing and improving it. Since then, Mark is concentrating on a Intersil Solomon is making the driver SMP compliant, cleaning it up and keeping up with the new firmwares from Intersil, and keeping up with new kernels. Solomon has also added pretty complete support for Wireless Extensions in 0.
This allow to turn a regular PC with a Prism2 cards into an Access Point, allowing other nodes to connect to it. In HostAP mode, the card does only the critical part of the Access Point sending beacons and simply pass all the Also, it is possible to load special firmware in PrismII card which allows the card to perform the full Access Point functionality by itself tertiary firmware.
It is well written, it was probably inspired by the various other driver floating around and is much more simpler than the linux-wlan-ng driver see section 3. What set this driver apart from the other driver is its support for HostAP mode.
In this mode, the driver act as an Access Point on the air and does all the In this mode, the driver also allows bridging through the regular Ethernet bridge driver of Linux. This explain why this driver is use by most Linux Access-Point projects. In other words : impressive work This driver was included in kernel 2. It's a fully featured wireless lan compliant with The Compaq products are rumored to be the Samsung one, with a new sticker The driver seems complete and well written, the new releases fixes more bugs and I had report of people successfully using it with Samsung cards and even some LinkSys and D-Link cards.
The main difference with the PrismII driver of Mark see section 3. After a strategic agreement with Intel, Symbol is back with a complete line of The card is mostly sold in the Pcmcia form factor, along with the Access Point. From Symbol, we can expect a design giving good quality and performance. The MAC has all the usual features of the The physical layer has the classic PrismII feature, supporting 1, 2, 5. Not surprisingly, the driver is very similar to the Wavelan-IEEE binary driver except for being full source , to the point of mentioning "Turbo" cards what Symbol calls "High Rate".
The driver is well written, has an extensive collection of module parameters and has been tested successfully with Symbol, 3Com and Intel cards. Lee plans to add Wireless Extensions and fix the few remaining bugs The version 1. X and disable power management doesn't work on latest firmwares. Symbol has recently release a separate version of this driver to support Compact Flash cards. Compact Flash cards need a specific driver because they don't have the firmware stored on the card and therefore the driver has to download the firmware to the card after each reset.
Olrog ericsson. Ericsson is of course the main driving force behind BlueTooth see section 8 , but they realised pretty quickly the BlueTooth would not fulfil the need of the Wireless LAN market. Due to the success of As such, this product has all the usual This is only the second driver written by Christian from scratch, after the BreezeCom driver see section 2. And as usual for him, the source code is well written, concise and clean. Impressive job! This driver is very new, so I don't have yet report of its use.
The driver seems to support only a minimal set of configuration and statistics for now. Christian told me that it should work with other Symbol cards with minor changes, and that the driver has been tested with IPsec and MobileIP.
I hope to have more info about it at a later date However, the Compact Flash cards don't work with the standard Orinoco driver because they lack built in firmware. This is the same reason why there is two different Spectrum24 drivers see section 3.
Pavel has created a new driver based on the Orinoco driver and SpectrumCF driver for those cards. It is similar to the regular Orinoco Pcmcia driver, but add the firmware download at each reset necessary for those cards. As the core of the driver is common with the Orinoco driver , this driver has the exact same feature set which is quite extensive - see section 3. This driver is now integrated in the Orinoco driver collection v0. It is now part of the Linux kernel 2.
Note that for cards that don't require the firmware download regular Pcmcia cards , it is recommended to use the regular Orinoco driver instead of this one. Below is how to do that:.
