D Link Dwl-650 Driver For Mac



Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.


Last time we reviewed USB adapters for wireless networks of the 802.11b standard. Easy to connect and fast adapters are an excellent solution in many cases. Today we will test a different kind of equipment which can't do with USB anymore because of its high speed, but the compatibility with the 802.11b standard is preserved. So, we will speak about the latest modification of this standard marked 802.11g. But first of all let's see who and why may need it. What's the use of the new standard?Wired networks that use special cabling ensure data rates of 100 and over Mbit/s. But it's not always possible or desirable to lay cables. That is why solutions that use cables laid out before (HomePNA use home telephone cabling, HomePlug use the electricity supply network) are of much interest today in spite of their high price (it's possible to save much more on cable laying) and a relatively low speed - 10 or 14 Mbit/s. Networks of the 802.11b standard look very attractive because no cabling is needed, but the data rate is only 11 Mbit/s. If the conditions are excellent and all the equipment comes from the same company one can turn on the turbo mode to get 22 Mbit/s, but since the channel is divided into two (for the duplex mode), the maximum speed in one direction reaches 1 MB/s at best and usually runs into 500-600 KB/s. This speed suffices in most cases but sometimes it doesn't. Cabling can ensure higher speeds, but as I already mentioned it's not always possible. At the moment the developers are working on the 802.11a standard whichwill provide 54 Mbit/s. But the solution isn't that simple as it may seem.The 802.11b standard works at 2.4 GHz, while the 802.11a at 5 GHz. Thisdifference causes two problems - technological and juridical. In the firstcase it's clear that the standards are not compatible (802.11a isn't evencompatible with 802.11). The 802.11a can be used as a radio bridge betweentwo points but not for an office network or as a hot-spot because compatibilityis urgent here, and since 802.11b is more popular, the gap will be wideningas sales of Centrino based notebook PCs grow up. In office or home youcan use equipment of the same standard but what if your colleague alsoneeds the network access? There are universal solutions, i.e. access pointsand adapters which support both standards, but they are pretty expensive.Another problem is that not all channels of the 802.11a standard arepermitted in different countries. The frequency of 2.4 GHz is free to usein most countries. 5 GHz is not. The situation may change, but it won'tbe quick and everywhere. That is why this factor tells upon the developmentof the 802.11a standard.So, the developers were faced with the problem to catch up with the802.11a in speed preserving the frequency around 2.4 GHz and compatibilitywith the 802.11b. The problem was finally solved this year - the 802.11gstandard is able to work with equipment designed for the 802.11b at anyspeed the latter supports and also works at the speed up to 54 Mbit/s inits own standard. First devices have already reached the market and probablyneed improvement. So, today we will carry out some tests using two adaptersfrom D-Link and BLISS 500C notebook PC.D-Link AirPlusXtremeG DWL-G520This adapter is a usual PCI card designed for desktop PCs. All the stuff is packed into a rectangular metallic box which also servesas a screen and which is glued to a piece of textolite :) An external antennaand PCI connectors let it communicate with the outside world. The antennaconnector is standard and can be easily replaced. Also, you can see a LEDoutside.The adapter comes with a software CD, a user manual in 7 languages andan I/O shield which can replace a standard one if you want to install thecard into a low-profile slot.D-Link AirPlusXtremeG DWL-G650This is a variant of the previous adapter designed for the PCMCIA bus insteadof PCI, and it can be of much more interest for users of portable computers. The design looks less sophisticated without textolite. A removable antennais replaced with a fixed compact one. But there are two LEDs.The adapter is supplied with an in-depth user manual and a software CD.SoftwareThe adapters have the same CD because a 32pin version of the PCMCIA busis a special PCI modification and the contents of both adapters and theway they communicate are the same. By the way, some companies just offera PCMCIA adapter coupled with a special adapter for "desktop" users. I'mglad D-Link didn't follow them because in that case we wouldn't be ableto connect an external antenna which is realized in the DWL-G520 but islacking in the DWL-G650.Remember that the wireless network support in the Windows XP that worksperfectly for 802.11b fails for 802.11g. Operation starts just at 2 Mbit/s.That was exactly the problem in the Windows because we tried it in otherconditions and brought the PCs close to each other. The problem disappearedonly when the respective service in the Windows was turned off (on bothnetwork nodes).The management program interface differs a bit from the tiresome tabs,and it looks like the Web interface: hyperlinks and page opening in a frame.The first provides info on the current connection. I don't think it's neededto describe fields. The low connection speed on the screenshot is causedby the reason described above. Signal power and connection quality arenot displayed in the software version I use (the situation was the samewhen I tested the USB adapter) - the place is reserved but the functionitself is not realized yet.The next page lets you change adapter's parameters. In particular, youcan choose the functioning mode (point-to-point or infrastructure), channel,power saving mode. You can disable the automatic speed detection and fixit at a definite value as I did (though I'd better not).On the third page you can configure the data encryption mode or simplydisable it. But you'd better do it if you are sure that nobody would tapyour data. On the other hand, the WEP ensures pretty weak reliability (evenin case of the 128bit key), and it's still better to use an external encryptionmechanism.The next page is more useful for a mobile user. An owner of a desktop PCusually selects a network once and forever (at least, for a long time).A mobile user tends to change it. The profile configuration option canhelp him a lot.Here is a typical profile. It contains parameters which differ for differentnetworks. Thus, you can create a profile for every network to avoid changingparameters every time you change a network. This single factor makes D-Link'sutility preferable as compared to the OS own means (even when they startworking correctly).The last page just displays the MAC address, drivers and utility versions.The driver version is not 1.0 already, but the driver is not cardinallyimproved, that is why any problems can still be related with the software.Speed of operationThe testing technique hasn't changed: Ad-hoc mode, the same hardware platforms(Athlon XP 2000+ based desktop PC and Intel Centrino based notebook), andthe same AIDA32 for speed measurement. But today we have more than twopairs of tested devices, and I marked them with figures on the diagram.In the first three tests the notebook used the built-in LAN adapter(remember it's Centrino) of the 802.11b standard, and we changed only theadapters it worked with. The first two are D-Link DWL-120 and MSI UB11BUSB adapters tested lasttime (exactly in this order), the third is DWL-G520. In the first partwe tested its operability in the 802.11b mode and compared the resultswith other earlier tested models.The forth and fifth results were obtained with the same tandem: DWL-G520in the desktop PC and DWL-G650 in the notebook. Why two results? In ourconditions (about 10 m and one ferroconcrete wall) the connection speedwas 36 Mbit/s. It's three times faster than the 802.11b ensures. But itwas interesting to check the connection with the speed of both adaptersfixed at the maximum of 54 Mbit/s. The experiment didn't fail: the utilitiessaid the connection was 54 Mbit/s indeed and it didn't fall down duringthe test but...


The lights blink on it if I put it in, and a cardbus icon appears in the top right corner, but I don't get anything in Airport. PC Cards shows an unidentified Ethernet controller when I plug it in, and says atheros. Is there some guide for getting this to work on 10.5 (10.5.5 ideneb 1.3)
