Hi, I'm wondering if someone can help me.
I have a wired LAN with 5 computers on it ... and I would like to add 2 wireless computers to it (actually 1 computer that only has USB available, and 1 Series 2 TiVo). I'm not sure what hardware I need to do this.
I think I need a "wireless access point" device (instead of a "wireless router" ???)... and I guess 2 "wireless adapters" (???) or something like that? Do you think this is correct?
Also, does anyone have any suggestions for brand and/or models of equipment that would be good? (I have a NETGEAR FS105 for my LAN).
Many thanks for any help!!!

Yes, you need an Access Point. You'll need a free socket on your hub/switch/gateway/router on the wired LAN to connect it up.
For business use we normally use Symbol or Cisco gear, but that's quite pricey. Netgear, Linksys, D-Link all make cheaper ones. My home network is based around a Linksys WAG54G (version 1), which is a 4-port switch, ADSL router, and 802.11g wireless access point all-in-one.
You can get both wired and wireless USB network adapters. Again, look for 802.11g for the highest standard data rates (up to 54Mbps). For the TiVo, see their list of recommended adapters[^]. You really are restricted to what they support. You might as well get two the same. It shouldn't matter if the AP is from a different manufacturer than the cards, 802.11b and g equipment is now usually compatible.
When you set up your access point, you should change the administrator passwords, change the ESSID (may be called Network ID), turn on the highest compatible encryption setting (prefer WPAv2 to WPA, WPA to WEP - if the device hasn't got at least 128-bit WEP don't buy it), and turn off ESSID broadcasts. I see way too many APs that have seriously weak security or even running the default settings. If you feel really keen you could turn on MAC filtering, which restricts access to only the network adapters you specify.

Hi,
I have an 80GB IDE hard disk with multi boot with Linux and Win2k professional and plan to buy a Maxtor/WD SATA 250GB+ HDD. I was wondering if using manufacturer supplied software can I mirror from IDE to SATA. The pain of reinstalling 3 OSes and gazillions of softwares, some of which I have lost the registration info for, is not worth upgrading to me. I know using Ghost/Partition Magic I can achieve this but thats like spending $50-$80 more.

Hook both HDDs up to your computer, boot the computer using a Live-Linux-CD/DVD, partition the new HDD, use DD to copy your data over, reconfigure your boot-manager, unplug old hdd, reboot, if it works, throw the old HDD away or send it to me.

Does Linux dd command work with NTFS and its permissions? Thanks for the reply.

dd does a binary image of the disk, it actually doesn't have any filesystem concepts.

IDE hard-drives make great walk-away backup drives using a $30-$60 USB/Firewire case.

Hello everybody
Could someone please tell me how to disable the line in and mic in on a soundcard, or if it is possible. If possible could the solution be in C++. I have worked with the soundcard before and used the Windows Multimedia Library to allow the wavein and waveout commands etc, but I am trying to temporarilly disable the inputs on the card whilst an output is perfored to the speakers.
Thank you very much for your time.
Regards

I can't believe I just had the dumbest argument in my life with a guy that is trying to tell me that RAID 1 is useless.
He says that it 'cuts your server performance in half' and is trying to tell me that instead we should set the drives up in the servers as stripe sets and then have mirrored servers.
Sheesh…. Trying to build a reasonable system for a small company here (best performance for the buck) and here is trying to convince me to buy 2 servers to do what I can get one to do. I have used RAID 1 for years and never seen a noticeable loss in performance unless you do the mirroring in software and not with a controller.
Sure, if I was going for high speed AND high availability I would use mirrored stripe sets, but I still would not bother mirroring the servers. The company is not that big and does not have the cash to spend.
Just needed to vent.

Depends on your setup. If you have IDE drives and both drives are on the same channel, you are going to get something of a slowdown as IDE doesn't have asynchronous capabilities. But you're right, with a hardware RAID setup, and SCSI drives, you shouldn't see very much of a slowdown (one drive will always acknowledge before the other - the controller should not acknowledge until both drives have).

Does SATA suffer from this as well? I am just starting to take a look at this tech (always did SCSI before) and was wondering...

I'm pretty sure Serial ATA only supports point-to-point links, it is not a bus. Therefore yes, since each controller port only talks to one drive, the problem disappears.
Intel's current ICH6 I/O Controller Hub chip implements four SATA ports. Most add-in cards also offer four ports, I believe.

Thats what I thought.
Thanks.

Now the USB harddisk could not be recognized by the system.
How to repair it?
Thanks!

It should still be recognized.
Try replugging it into a different USB-port and into a different computer (using proper dismounting). This could be the solution to your problem.
If it is not, you have probably killed the indizes or partition tables. That happens when you unplug an USB-HDD while it is writing.
You may also have fried the USB-to-IDE bridge, which sits between the built-in HDD and your computer.
You might want to try to use the Administration panel (right-click on the "my computer" icon) to re-partition the drive. That is the quickest solution if there is no important data to recover. If there IS important data to recover, try using a different USB-to-IDE bridge and/or plug the drive directly into a IDE-channel and try reading it from there.
If its recognized, but not accessible, a disaster-recovery tool might help. AFAIR, SpinRite (www.grc.com) can recover destroyed indizes and tables.
Cheers,
Sebastian

I want to write a program in VB.Net which accesses my computer's COM-Ports. While using windows 98 this is no problem, because there's a DLL which I can use.
While using XP this is not possible because of HAL (Hardware Abstraction Layer).
I already know that with HAL, it is possible to access COM-Ports by open a file. The problem is that I don't just need the TXD/RXD port but also ports like RI or RTS.
How can I manage this?
(Maybe there are drivers who create a virtual COM port and translate it to HAL to use the real port?)

No, you can't access the serial ports by simply using IN/OUT instructions as you may have done in DOS. On XP, those I/O ports are restricted to supervisor mode (the kernel). You must use the serial communications APIs. Unfortunately this is one of the less-well documented areas of the Win32 API.
To be notified when the Ring Indicator or Clear-To-Send (i.e. the PC's view of the other end's Ready-To-Send line), use the WaitCommEvent[^] API.

Thanks to you, I've now found a way to use the PORT.dll with WinXP as well, and it's nearly the same as with win89: You just have to set the outports to 0 at the beginning.

I've never heard a thing like this.
Windowsupdate does never change hardware settings if the user does not select driver updates from windowsupdate.
Don't try it, just do it!

As long as you don't accept any driver updates you should be alright. I foolishly accepted a new driver from Microsoft once for my wireless card, and it caused the card to cease working, and the computer to become unstable. Fortunately, XP now has the Restore function - you could make a restore point, then do an update. If anything breaks, you should be able to roll it back. As far as I've seen, there is no check for signing after you have installed a driver, and you should not have a problem with XP trying to remove an unsigned driver.
