I have a D-Link DI-713P and it is suppose to be quite similar to the
SMC.
Do you know if the antenna connector are also TNC-R ?

Thanks in advance

Alain

| Nope.  Only one antenna is on at a time.  The access point
receiver

tosses a
| coin to decide which antenna to use for that session.  It's called
| diversity reception and does improve the reliability when dealing
with
| moving laptops or reflections.  However, the two antennas do NOT
act
| together to form some kind of gain relationship that will improve
| range.

|
| That's not right.  Did you actually try it without antennas?  Even
the
| plastic case access points do NOT work without antennas.  As I
said
| before, if you're only getting 20ft or so, something is busted.

|
| The good:
|   Wavelan/Lucent/Orinocco/Avaya/Agere
|   Alvirion/Breezecom
|   Cisco/Aironet
|   3com
| The bad:
|   SMC
|   Linksys
|   D-link
|   Raylink
| The dubious or one's that make me worry:
|   Netgear
|   Buffalo
| The interesting (there's hope):
|   Belkin
|   Zoom
|
| Each of these manufactories has good and bad products depending
upon
| what you're attempting to accomplish.  I would not use a "home
| networking" grade of wireless for a "mission criminal" enterprise

| Look at the FCC ID number on the serial number tag.  Then go to:
|    http://www.fcc.gov/oet/fccid/

| most of the cheapo home networking abominations are made by a
small

| really bloated PDF files with some nifty test results and some
| gigantic JPG's of what's inside.

|
| It will still work with one.  There are companies that sell
pigtails
| to adapter the Reverse TNC connector on the back, to a standard N
| connector, and then to a higher gain antenna.  Depending on your
house
| layout, it may help.  However coax losses are horrendous at 2.4GHz
and
| a long coax cable will not work.
|
| >What is a TNC-R connector?
|
| The FCC had this great idea that if they forced the manufactories
to
| use non-standard connectors, people would be less tempted to add
power
| amplifiers and external antennas.  Fat chance.  The TNC-R is a
| standard TNC connector, with the center pin as the opposite sex.

the WAP.
|
| The TNC-R connectors are on the back of your SMC access point.
Most
| PCMCIA cards do NOT have an external antenna connector.  However,
the
| Wavelan/Lucent/Orinoco/Agere/Avaya card does have an MC-Card
| connector.  Many cards can be modified (i.e. butchered) to attach
an
| external antenna.  Spare me the effort right now.
