1. RE: [Karlnet] AP-1000 loses one radio interface (score: 1)
Author: Thomas Giger TGC <thomas.giger@tgc.de>
Date: Wed, 5 Nov 2003 08:22:39 +0100
In the past, we have had 2 symptoms that need to be differentiated: 1) A radio interface completely stops sending (keeps receiving). This not only happened at CORs, also at the CPEs. The solution was

Roberto, We do use bridging over only one AP hop; however, the Karlnet MAC table is fairly large, as far as I remember. That should not be your issue if you cascade bridged links. Thinks to consider:

Not only that. CardBus is the 32-bit successor of 16-bit PCMCIA. That is, these a and g cards use it for performance reasons. Same as with the transition from 10 Mbps (16-bit) ISA cards to 100 Mbps

Turn off polling and you may be screwed even more by self interference from hidden nodes talking into the AP. We've tried that and it doesn't work. No, polling is what you need. But if you want to b

Whatever the official Karlnet answer will be: 2 years ago I've seen a Lucent Orinoco presentation that mentioned an additional TurboCell operation mode which would allow satellite-satellite polling f

That's what I would expect from a polled system. Note that the polling frequency has no correlation to your ping interval; the activity of other systems influence how frequently this (idle) client i

Most of our customers require that we assume an address within the private range they have been using and would not let us dictate them a renumbering orgy. And of course, you will find that at least

Kevin, if you answer my question below, I'll answer yours :) The answer for you is: Bandwidth management ought to be done before the traffic hits the segment that you want to manage, i.e. on the outg

As I said before, at this position in the datastream, a BCU can only throttle TCP based applications (like for example SMTP messages going out and POP3 download data coming downstream) because TCP wa

Kevin, here we go again :) --^^^^^^^ This is always very interesting b/c everybody needs more channels and less interference. The FCC has recently announced plans to open the 5.475 - 5.725 GHz spectr

The benefits: Higher data rates The physics: If more information is encoded (at the same bandwidth of 20 MHz), more energy is needed. That is, you will see an increase from -82 dB receiver sensitivit

Kevin and all at Karlnet, The FCC is about to ratify the 5470-5725 MHz frequencies under the same terms and conditions as ETSI, i.e. 30 dBm output power, DFS and 6 dB TPC (aka IEEE 802.11h). What are

I guess I should give a more in-depth explanation of the TC Linux driver - Kevin is usually helpful, but he is also quite short in his answers (no offense meant, must be a result from the number of q

Ricardo, Probably the most recent kernel you get it to work with is 2.4.9 - this is somewhat better than RedHad 7.1 but RedHat 7.3 is way "too new". It also depends on the gcc version, BTW. More rece
