Does anyone know if you can upgrade the antennas on the dir-655 if so what kind of antennas can you get for it?
-
yes you can upgarde your antenne with other antenne. look at the dlink site and you know what for an antenne they have. I also upgarde my antennes with 6dbi antenne each.
-
what model number is your antennas? Do notice any difference in performance?

Anyone one of those 4 antennas will work with dir-655?
-
i have different antennes with my dlink router and i have good performance yes.
1 dlink original, one hawking and one sitecom antenne. So long as het have an rsma connector it will work. (both antenne's are 8dbi) and one is still tghe original antenne.

Only the Xtreme N antenna is intended to work with the DIR-655. The benefit would be placement. It is more common for the antenna to be used on the PCI card , so you can move the antenna to the desk top instead of buried behind the computer (pci slot oc computer shoved into tower space on side of wood desk).
-
Alien what's the model number for your hawkings antenna i think i'll change my antennas.
-
What kind of antennas come with the DIR-655?
-
Please note:
Changing the antenna to a 3rd party may cause undesirable side effects (e.g. rebooting, poor wireless performance, etc)
We have a upgrade available for that unit ANT24-0230.
I've used it in my home and gained an extra floor of coverage.
-
What's the gain on the ANT24-0230? I never found anything that said that they actually performed better than the stock antennas, just the advantage of placement.
-
Placement is the biggest single advantage. Anytime you add an antennae you will not be "boosting" the signal, only shaping it.
The perfect antenna is a zero mass point in space and it's signal area is a perfect sphere.
Take the type of antennae that came with your DIR-655 or the antennae on the ANT24-0230, imagine a torus shaped zone around the antenna, this torus is your signal area. With dipole omnidirectional antennae (which both of these antennae are) the shape you get will always be a torus with little to no signal in the axis the antenna is pointing. Gain is a measurement of how much this area is distorted into a torus as opposed to a sphere.
Additionally there are 3 more issues at hand
One is that the cable leading to the antenna is technically an antenna itself and will not only have associated losses due to resistance but it's own signal area. This is why we suggest using the original antennae if your environment will allow it.
One is that if your antenna and your receiver have different impedance then you will create a standing wave which will cause even greater losses, this is the prime reason we will always suggest using a D-Link antenna approved for your device.
The last is that since we have 3 antennae here we are technically working with a battery of antennae which will have a special and complex interaction, due not only to their own interfering signal areas, but due to the actual signaling technology of draft N (which is written to take advantage of having this battery configuration). This is why we always ask the position your antennae are in and why we strongly suggest getting a battery of antennae (such as the ANT24-0230), as it is shaped to take advantage of these harmonics.
I hope that helped.

i'm thinkning about getting a 9dbi antenna
-
i bought it in the netherlands, and hawking antenne's are very good. I think you look at their website. and my antenne is al an older one.
-
i was looking at ebay they have a 9bi antenna that is compatible with dlink same kind of connecter
-
Is it rated for impedance?
-
what do you mean fatman?
-
One of the more important ratings on any piece of wireless equipment is impedance, without getting into a long explanation suffice it to say that if this value does not match between your router and antenna then your signal will be drastically degraded.
Most wifi equipment (including the DIR-655 I believe) is rated for 50 Ohms of impedance, however some antennae (particularly of disreputable sources) are either not impedance rated and tuned or may be rated and tuned for a different impedance.
For more information as to why this is important please see the below wikis.

Lycan - do You know where to buy ANT24-0230 in "the old world" ?
Itīs listed in the dlink.com site but not in the .dk or .co.uk sites !!

Well...I live in Denmark....so my Hollandish/Nederlandish (or what ?) is a bit sluggish....
I have just ordered a ANT24-0230 from the US...
-
.nl makes it a Netherlands domain, so my guess here is that it would be Dutch, to my knowledge they don't have any special variations therein, according to the wiki that is the national language though they have some regional languages that look like they might be fun.
That said, am I reading this page wrong or are they wanting better than 100 Euro for all of their products?!?!?!?!?!?!?!?!?!!?!?!?!???!?!?!
-
Okay...my "Dutch" is a bit sluggish....and yes Fatman.....It seems that nearly all there products
are 100 things.....well Holland is a very rich country....or ???

Question for Fatman
i have a 3000 sq ft. home. My Modem and DIR 655 are upstairs with the modem pointed out the window for better signal(clearwire)....
I have two computers--one desktop which is located downstairs past the kitchen and into an office on the other side of the home--this is my furthest away point. I am using a DIR 552 beta SW and getting approx signal of 70-90%. with Transfer Rate staying at or around 160 instead of 300 like what it is rated for.
My other is a laptop is downstairs in the living room that i just added a DIR 652 and it gets 100% signal with 300mbps.
My Question is I want to Add the D-link ANT24-0230 and run the antenne up through the ceiling and actually get it closer to the Router. BUT the Cabling on the Antenne is only 3.8ft. Is there anyway to change out the cabling to say 100ft?
Thanks for Any Replys.

It is possible that you could find 3 R-SMA extension cables of that length and install them, however cable losses beyond a meter of cabling become incredibly stifling. And the cables will be acting as antennae themselves and won't be guaranteed to have the constructive interference expected by a proper antennae array.
it would be much better to find a way to move the router closer to the point you need. Ethernet can be taken to 100m without degradation, and it's cheaper.
-
Thought about that --went up in the smaller portion of the attic to see if i could just run the cable over but that would be impossible --the trusses from the flooring is in the way of even getting to it.
What about Power over Ethernet?
DP
-
I am a bit confused at the mention of PoE, please elaborate.
The DIR-655 does not support PoE in any way so my guess is the answer is no.
-
PoE is moving AC current over Ethernet cable (CAT 5/6) however you may be in reference to Ethernet over Power which allows you to use the wiring in your home to transmit ethernet connection between a sending unit and a receiving unit. which would work very well as long as both the sending unit and the receiving unit are on the same curcit on the Fuse Breaker.
-
I think I have solved my problems--What i thought was impossible turned out not to be. I had to create another access into the attic from the garage(which is where the office is next to.
I am able to get into this portion of the attic and with an electrical fish line i bought at lowes i was able to create a path to go upstairs into the attic up there. Then run the cable over to the bedroom and down through the ceiling and connected to my DIR 655 DIRECT CONNECT--YEA!!!! I can take my DIR 552 back to Best Buy now.
one more Question...Since i am up here and doing this i might as well Run CAT 6 cable correct? and Will the Cat 6 connector have the same RJ45 connection--i looked around and it appears to be the same connection.
and Finally ----Wait on Verizon to RUN FiOS in my town sometime in the near 100 years and I will be able to bump up my downloads to 50/10mbps. HAHAHAHAHAHA!!!!!
DP
-
Sounds like you got it all figured out... yes it is advised that you run CAT6 so that in the future when you upgrade your PC's adapter to GB connection you will not have to re run wire.

MasterChiefDutra,
Question, In looking at what i am doing i guess i am downgrading back to 10/100 right because of the NIC that is in the Desktop correct? So I will need to upgrade my NIC in the desktop right?
ANy Suggestions for a NIC?

-

Just a small clarification...
Power over Ethernet (PoE) is transmitting DC voltage and data over the same Ethernet cable.
Power Line Communication (PLC) is transmitting data over a conductor also used for electrical power transmission.

Correct. Also the ethernet being used must be CAT5e por better.
As for the NIC, take a look at the DGE-530T. Reasonably priced Gig nic. We also have a PCIe Version, DGE-560T I believe.
-
I agree With Lycon those are both very good products.
-
Well--I am finally set up with my D-link Family.
My Setup--is Sweet!!!!!!!!!!!!!!!!!!
Computer 1-Desktop hooked directly in with Gig NIC into CAT6 cable to my DIR 655...SWEET!!!
Computer 2-Latop with DIR 652 downstairs living room.
Hmmm --You Tell Me !!!!!

Peace out
What I dont still understand is If I set the Router to be "N" only why does it still say "ng"????
DP
-
Probably a small bug in the firmware. I'll see if i can replicate.
