I have a Sony Vaio with an integrated b/g Wireless card. My brother got a linksys b wireless card. After a little fiddling we got an ad-hoc network set up between us. However, when we ping, everything will be fine, before suddenly we will get lots of dropped packets. Even sitting next to each other, in the middle of nowhere (so no interference I would have thought), I will randomly get a big set of dropped packets, then everything will be fine again. Sometimes the connection breaks entirely. Any ideas? Any help would be extremely useful!

Geez man,

You are really reaching expecting a bunch of technophobe arty mac lover types to help ya with a tech question

Anyway, here is your anwser.


Here is a longer anwser.

A 802.11x wireless connection sucks.
In essence, you have a collision detection scheme implemented over radio.
Because you can NOT detect packets being sent across the wireless
(to do that, you would have to listen to all the devices broadcasting in your range)
the way collision detection is implemented is by statistical time division.
What that means your card 'remembers' when it was successful sending packets
(it knows that by receiving ACKs) and tries to send further traffic in those time slots.

So basically the device works as expected.

Alternatively you could have a really wacky compatability issue.
Wireless NOT== Wireless.

I received the following advice; "Do not buy the wireless gear you can afford"

"The future is not written in stone.
It is written day by day,
What are you writing today?"

Wulfius: Thanks for such a contructive and complimentary comment about our community here. We may indeed be 'arty types' (well, some of us may be) and some of us may be 'mac lovers', but no one here is a technophobe. On this board you will find one of the most diverse technical backgorunds anywhere, from beginners to experts...and above and beyond that you also have a group of people who are verym very good at researching and finding out information. I realise that you may have meant your comment as a joke, but, if so, make that more clear next time.

Yeah guys, I know there are people on this who enjoy being annoying (eg Metahuman. I know you will think I have got the name wrong because you are just that sort of condescending, patronising idiot, but I am talking to you!), but they are not even worth a second of most people's attention.

Using an access point setup out in Germany I can get a connection, even between rooms, with absolutely no dropped packets. Is this dropping pecular to ad-hoc, or the system I am using, or is something else going on?

Again, any help much appreciated!
