DNS lookup failed with wireless repeater

Pvsmith2 — Fri, 03 Jun 2011 19:06:12 +0000

so iv had this problem with two wireless repeaters now. when im connected to just the router, i am able to access the internet. however when i plug in and set up the wireless repeater ( the latest one is a amped wireless sr300) it works for a few min and then i get a “DNS lookup failed” when trying to access sites.
this repeater replaced a hawking hwren1. which would work for a few min and then lose the network.
i believe this is a problem with our internet connection into the house, but could it be a caused by the router? (wrt400n) our isp says its not their problem and that its our router, but this is the 4th one in under a year

i have little networking expirence, i am pretty much learning as i go along

Wireless channel architecture

Nogirs — Mon, 16 May 2011 17:47:30 +0000

In your article of designing 802.11n, you state ‘Channel architecture: Nearly all products use multiple channels to create micro-cells,
but at least two vendors use a single channel to create one big RF layer. The latter clearly cuts
roam time when clients move, but trade-offs are hotly debated.’

What are teh trade-offs that are hotly debated and where can I find articles to read? Thanks (enjoy your articles and tips)

Psion Teklogix connectivity

STCA — Thu, 04 Nov 2010 11:20:44 +0000

We have a Psion Teklogix Wifi installed in our warehouse. It consists of a 9150 controller and several 9150T Access Points, each with two antennas. We use Tess 5250 emulator on the 7535 handheld. The problem is that we very seldom can log in to the iSeries from the handheld. It works maybe 5% of the time and we don’t know why. Can anyone help us?

Toshiba Laptop (wireless – netgear router) Windows Vista to print to Gateway desk top Windows XP with HP Laser Jet 2100 PCL6

Sweetie1 — Fri, 29 Oct 2010 22:47:56 +0000

I have a wireless (netgear) network for my Toshiba Windows Vista laptop and I am trying to print to a Gateway desktop Window XP with a HP Laser Jet 2100 PCL6. I have turned on the sharing for the desk top and tried to add the driver to the lap top but it said it was incompatible so I browsed the internet and downloaded AFICIO BP 20 Series PCL6 that supposedly is compatible with the HP Laser Jet but still cannot get it to print from the wireless laptop.

Station with a mac address 00:11:22:33:44:55 shown on wireless clients

Truth — Mon, 11 Oct 2010 22:53:29 +0000

station with a mac address 00:11:22:33:44:55 shown on wireless clients:

Multiple Clients have same Mac address 00:11:22:33:44:55

I guessed it might be an issue from
some of the NIC manufacturers.I am wondering what is the impact to the
users on the wireless network will be?

If two users have the same mac address what will be the impact on the network?
