Nikon D2x and High Speed Crop

Just an interesting observation....
With Aperture and Tiger, Nikon D2x images shot with the smaller MP High Speed Crop (HSC) mode displayed 24 extra columns/rows (depending on orientation) of pixels; thus an image that should be 3216x2136 showed up in Aperture as 3240x2136. The extra pixels included several rows/columns of garish purple and green pixels than needed to be cropped. This is fine for one image, but not suitable for several hundred (such as shot at a sporting event). In addition to the lack of support for .xmp import, this is one of the most frustrating things about Aperture (for me at least).
With Tiger this could be traced back (I'm guessing) to Core Image in the OS because other apps using it (such as Preview) displayed similar results. I was hoping for better results with Leopard and was disappointed to find the similar side effect. But I just checked and Preview, iPhoto, etc. no longer show these extra pixels in Leopard, only Aperture. My hope is that Apple will address this in an Aperture update in the near future (perhaps a RAW Fine Tuning 1.2 option).

I doubt that it's the camera, as the issue doesn't arise on exported pics. That said, as there are only two posts on the forums (yours and the one you refer to on the Aperture forum) it's possible that a: this only arises in very limited circumstances or b: it's local to your computer rather than a bug proper.
Create a new account (systempreferences -> accounts) and make a library there. Import a few pics and see if the problem is repeated there.

Nikon D2Xs / RAW(NEF) / High Speed Crop issue

I have a problem with my D2Xs when shooting in RAW with High Speed Crop enabled.
When importing into iPhoto (08 - Version 7.1.4 (371))the imported image shows a Green and Purple line down the right hand side of the frame.
It doesn't show when exporting the original file from iPhoto to another program (CS3 / Preview).
It could be the one reason that I finally have to say goodbye to iPhoto, and look at alternatives.
It was reported last year in this thread http://discussions.apple.com/thread.jspa?threadID=1260989, with no replies. Any ideas or response on this Apple?
Cheers

Digital start trigger and high speed camera

Is there any particular option or way available in LabVIEW to initiate the data acquisition and high speed camera using a digital start trigger? If yes, shall I create a task for high speed camera and then synchronize it with the other tasks?
Kind Regards,

Hi Helen19411,
The way to trigger data acquisition in LabVIEW is to use the 'DAQmx Start Trigger VI'. To set this up I recommend taking a look at this example:
http://www.ni.com/example/25282/en/
Without any information about the high speed camera you are using, I can't give much advice. If the device is viewable in MAX then you may be able to create a task, and so long as you synchronise both channels in your code, the digital trigger should activate both events.

Synchronisation of M Series and High Speed Digitizer

Hello everybody,
i just have a question regarding synchronisation/timing of two different PCI cards (M-Series PCI 6220 and High Speed Digitizer PCI 5112, connected via RTSI cable).
I wonder how I can synchronise signals, because those cards use different mechanisms in Labview for timing and synchronisation.
Can anybody tell me, how I can synchronise the clocksignals and let them use the same trigger (actually I want to use the external trigger of the 5112)? Witch VIs do I have to use?
Thanks in advance
Oliver

Hello!
First of all many thanks for your reply.
Exporting the external trigger from the 5112 to 6220 via RTSI works.
Synchronising the clocks in the same way as you wrote doesn't seem to work. May be I did something wrong.
What I did was the following:
I exported the "reference clock" signal of the PCI 5112 using "niScope export signal.vi" to RTSI 7.
Than I used the daqmx "sample clock.vi" to configure the
clock. I used the instance "sample clock" with "dev1/RTSI 7" as
the source (dev 1 actually is PCI 6220) and as sample mode "continous
samples". I started the PCI 6220 (daqmx) first, after that I started
the 5112 (niScope).
Running this vi I get the following error:
"ADC conversion attempted before the prior conversion was complete.
Increase the period between ADC conversions. If you are using an
external clock, check your signal for the presence of noise or
glitches."
This is still a small problem, but meanwhile I came to a bigger one:
I thought I could use the 6220 in the same way I can use the 5112:
I want to fetch (or read) data on both cards contionously but also
periodically. The period time is given by the External trigger I
mentionend before. Till now I didn't find a way to aquire the data from
the 6220 in records of a given length (let's say 100 samples, at 1kHz)
every time the trigger occurs (External Trigger rate is about 250 Hz).
This is possible with the 5112 board, but I wonder if this is also
possible with the 6220?
Kind regards
Oliver

Advice on buying camera for stills and high speed video

Hello video pros,
I'm a music composer who occasionally dallies with some simple photographic and video work. I'm looking for some advice re picking up a camera to make some simple videos, but with the highest quality I can get with consumer grade gear.
I am pretty much ruling out consumer grade camcorders for two reasons: One is that I want to be able to shoot high quality stills and make stop motion videos from very high res stills. The other is that I don't need audio recording at all because the video will always be just to accompany music - simple music videos basically. So I'm much more interested in the recent mid range point-and-shoot bridge cameras with full HD video modes rather than camcorders - they seem to cover more realistically the range of things I want to do.
My main question is regarding shooting at higher frame rates than 30 fps. I'd like to shoot video at a minimum of 60 fps (or higher) to then playback at 25 fps to get that smooth, slightly dreamy motion effect. There are a few cameras out there that offer high speed video modes, but most are nothing more than a gimmick because the res is so low that the resulting video is unusable. However a few cameras now seem to hit a sweet spot, offering 60 fps recording at HD res, and also 120 fps at 640x480 which (at a pinch) is usable, at least for stuff destined for simple web use.
The cameras I've narrowed it down to so far seem to be the Nikon Coolpix P500, the Panasonic Lumix DMC-FZ40 and possibly the Fujifilm HS20 EXR. I also was vaguely interested in the Casio Exilim HS cameras, but they seem to only offer high speed video modes that are pointless - 1000 fps at a completely useless low res, and 120 fps only at 640x480. The others I listed seem to offer at least 60 fps at some kind of HD res, so I'm assuming that with these cameras I could shoot decent looking video which would then play back with that slightly hyper real slow-mo effect when I import into FCP at 25 fps. Is this correct? Or is it the case that when they say HD video @ 60fps, it's some kind of interlaced mode which means you can't play back at a slower frame rate to get smooth slow motion?
The other thing I've noted is that all of these cameras do record HD video, but it's always compressed in H264 format. I understand that this puts a serious limitation on how much post-processing you can do to the video afterwards. Highly compressed video will begin to show image artefacts very quickly when you apply effects as opposed to higher quality (bigger file size) video compression. But I think I can live with that given that for the stuff I want to make, it will just be simply edited and only lightly graded. However, of the cameras I'm looking at, the Lumix also records in a format called AVCHD which (I think) does full HD at 17 Mbps. Does this mean that it's basic video quality is significantly better than the other choices? That said, from the specs it's unclear if it actually allows shooting at higher frame rates which you can slow down at playback.. the way it describes 60fps mode makes it sound like it's just interlacing so you don't actually get a higher number of images per second to then be able to play back at a lower frame rate. This for me might rule it out because I really want the creative effect of high speed video, even if it's only the subtle effect of 60 fps slowed down to 25.
So in summary, I'm looking for a camera capable of creative shooting (high quality stills to make stop motion videos, usable-quality HD video along with at least some degree of high speed video at a resolution that is still usable) to make interesting and artistic footage to accompany music. The destination medium is the web, so even though I'd like to get the best quality raw material to work with, the final destination is not exactly a cinema screen. As a pro in a related industry, I'm all too aware of the pointlessness of buying outlandishly over-specced gear that is far beyond your level of expertise. So I want to keep it simple and realistic, budget-wise, given the level I'm at. Nothing more than say $800 US. A seriously high end camera would be wasted on me, and I think it would be wiser to invest in useful accessories like a steadicam merlin and decent tripod rather than blow loads of cash on a camera far beyond my skill level.
Apologies for the long post, any and all advice would be very welcome and appreciated! And feel free to correct me if my assumptions are wrong, and suggest any gear that I should consider looking at.

Hi, thanks for your input. I'm aware of the fact that my question is a bit OT, but I'm just looking for input from people with more experience and broader information in this area than I have myself.. I know people are here to talk about FCP, but I'm betting many editors and film makers who work with FCP will have more insight in this area than I do.
I've been reading every review I can find at dpreview, and also am watching as many test video examples I can find on the internet, mostly on vimeo because the ones on youtube look pretty awful. I just am reaching out to get some actual experience and advice from people who might give me pointers on what to look out for.
As for 60fps not being fast enough, I know what you're saying. But for me, even 60 fps slowed down to 25 fps on playback is enough of an interesting effect, as long as the actual quality of the footage looks good to start off with. I like the subtle effect of slightly slower than real motion when it's real, bona-fide high frame rate slowed down. Artificially created slow-mo using plug ins looks cheesy to me, and the gimmicky super high frame rates of cameras like the casio exilim (where the resolution looks like a mobile phone video from ten years ago) are completely useless.
I've seen lots of examples on vimeo of stuff shot with DSLRs from Canon and Nikon at 60fps and then played back at 25 or 24, and it looks plenty nice enough for what I'm after. But am I kidding myself that I'd get anything near as nice with the price range I'm looking at?

I have one application that has requirement to do low and high speed acquisition. I want to change sample rate while running. BUT... I have E series Device

I am writing control software for a process that is usually dull and
requires only 10 Hz acquisition rate. At particular times during
the sequence, however, we are interested in looking at a couple of
channels at 1000 Hz. My approach so far is to configure my
Buffered DAQ to run at the higher rate at all times. When we are
in the 'high-speed DAQ' mode, the program logs every point to
disk. In the 'low-speed' mode, I am picking off every nth (in
this case, 10th) point to log to disk. At all times, I update my
GUI indicators on the front panel at a maximum of 4 times per second (I
find that anything faster results in an uncomfortable display), so I
fill up a FIFO with data in my acquisition / logging loop, and read the
FIFO in the display loop. The data in my GUI display can be up to
250 milliseconds off, but I find this acceptable . As a side note, I
need buffered Daq with hardware timing, as software timing results in
lost data at 1000 Hz.
This all works fine and dandy, but I am convinced that it is not the
most elegant solution in the world. Has anyone developed a
buffered DAQ loop where the scan rate can be adjusted during
operation? I would like to change the rate of the E-Series card
rather than relying on down-sampling as I am now doing.
The reason I have concern is that at the moment I am simulating my AI
using MAX and when running the down-sampling routine, I consistently
miss a particular event on the simulated data becuase the event in
question on the simulated data always occurs at the same 'time', and I
always miss it. Granted, while it is unlikely that my measured
signal and my acquisition are perfectly synchronized in the real world,
this particular situation points out the weakness in my approach.
More than anything, I am looking for ideas from the community to see
how other people have solved similar problems, and to have you guys
either tear apart my approach or tell me it is 'ok'. What do you
think?

Adding to Alan's answer:
One of the problems that comes with these tricks for variable-rate acquisition is being able to match up sample data with the time that it was sampled.
If you weren't using either of E-series board's counters, there is a nifty solution to this! You'll be using 1 of the counters to generate the variable-rate sampling clock. You can then use the 2nd counter to perform a buffered period measurement on the output of the 1st counter. This gives you a hw-timed measurement of every sampling interval. You would need to keep track of a cumulative sum of these periods to generate a hw-accurate timestamp value for each sample.
Note: the very first buffered period measurement is the time from starting the 2nd counter until the first active edge from the 1st. For your app, you should ignore it.

New to Macs AND high speed internet. I'm a little unsure of what I'm doing.

I just bought my first iBook yesterday, and today my roommate subscribed to our local cable high speed internet. I'd like to configure a wireless network for both of us to use. Problem is, I have the Mac, and she has a desktop PC. Is there a way for the two to use the same wireless connection?
I'm sorry if this sounds like an elementary question, but I just want to make sure that I'm doing the right thing and that I get the right equipment. Thanks in advance for any help you all can give me.

Yes, you can use the same internet connection with a wireless router. Once the router is configured for your ISP (most have "Wizard setup" discs for PCs...from the Mac side you can use your browser to set it up) the iBook should find it and ask if you want to join the network. Just get a 802.11b/g compliant router.

Enabling/ disabling wide channels doesnt change the avarage transfer rate significantly.
These are just a few examples of all tests I have done, I have tried every possible configuration and took screen shots of almost 80% of the test (if someone is interested in reviewing this).
I couldnt find a single configuration in infrastructure mode that is as fast as the ad-hoc connection, so I assume either apple's setup for ad hoc and using channels is different to infrastructure or the airport express simply is unable to perform the same way as the wifi cards being used inside my Macs (which is my conclusion unless someone proves me wrong).
-------------------------------------------------------------------- Keep in mind, my findings show a 100% faster network in Ad hoc mode on a 2.4 Ghz connection
This is quite unsatisfying as I have bought the airport express on Feb 9th 2010 and it was the latest available model according to local genius bar.
So to quote apple: "The AirPort Express Base Station is based on an IEEE 802.11n draft specification and is compatible with IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g." yes it might be compatible but doesnt allow you to fully operate at those specifications or has anyone been able to achieve this somehow?

why didnt I find this any earlier ...

Camera Connector with Nikon D2x and 5G 60gb iPod

Has anyone had experience with the D2x (Nikon) and the camera connector on a 5G 60gb iPod?
The camera is compatable with Mass Storage and PTP. The camera works great with iPhoto...plug it in and iPhoto opens and you click the button to download.
Also, I see that the new iPod has a longer lasting battery. Does this help when downloading a large card.
By the way, I called Belkin and their camera connectors are NOT compatable with the new 5G models and the guy said that there is nothing on the drawing board.
G5 Dual 2ghz Mac OS X (10.4.4) 3.5gb RAM; 400gb HD

I purchased the 60gb iPod-Video (5G) and after several failed attempts I found the proceedure to upload photos on to the iPod using an Apple camera connector with my D2x. Here goes:
First, reset the ipod (just a precaution...hold down the center button with the Menu button for 6 sec). The screen will go black with a golden apple in the center. The menu will display after a short period.
Turn on the ipod (if it isn't already on from the above proceedure).
Plug in the camera connector to the iPod (without the USB cable attached).
Attach the USB cable to your camera and turn on the camera.
Plug in the cable from the camera to the camera connector which is attached to the iPod.
Wait 20-30 sec and it should work.
I tested the speed in both PTP mode and Mass Storage mode. The import for both was 200mb.
PTP = 3minutes 10 sec
Mass Storage 1 minute 59 sec.
The battery did go down a lot (about 1/4 after both imports), but after you detach the camera connector and go back to the main menu, it seems to go back up to about 95% full.

Verizon's new FiOS GigE Wireless N Router and High Speed Internet

So I got a deal in the mail to get an upgrade to [50/25] Mbps Internet (I currently have [15/5]...when I was reviewing it on line this message came up...
Verizon will provide up to [50/25] Mbps Internet with a wired connection. If you use your Internet primarily for wireless or WiFi connections, you have the option to upgrade to Verizon's new FiOS GigE Wireless N Router which will maximize your speed delivered through your wireless connection.
Upon completion of your order, you'll be provided with information for purchasing a router at Verizon's online equipment and accessories store.
I am VERY interested in getting super fast internet...my current internet is really good but it wouldnt hurt to bump it up. I have several devices using internet in the home...most of them wireless (including my PS3). I currently use a Verizon Actiontec router.
So here is my question...do I really need to get the above router to take advantage of that [50/25]? Also one other thing...My house is fairly large and I would really like to have two routers...is it possible to use two routers or a setup to have one upstairs and another downstairs?
Thanks in advance for the answers!
-Jest

There are a lot of variables that affect wireless range.
Walls, interference, other networks in the area, etc.
You don't indicate which older Actiontec you have.
Wireless capabilities also vary by Actiontec hardware revision (A,C,D,E,F,G,I).
In general, wireless range for 802.11n is somewhat less than 802.11g, even though the bandwidth is higher.
This is especially true on the 5Ghz band (which the latest Actiontec doesn;t support).
If you only need another 10 feet, you could try moving the router, or replacing the antenna with a high gain antenna.

Unable to keep btvision off and high speed searchi...

Am hoping someone can help please, our btvision box wont stay off apart from at the plug. Also when it is on it flicks through all the channels when on the tv guide page, this happens as well when on the btvision page. So it is impossible to watch anything. Ive tried changifng battries in remote, rebooting box, unplugging, and nrothing is working, this has been like it for the past 2 days, please help! Thank you.

I had exactly the same problem when I received a new black box. It would work for a time and then would do the scrolling channels/menu's thing. I reported it to BT Vision on 0800 1114567 (I think) The service wasn't brilliant, but they eventually sent an engineer out who installed a new box which has worked perfectly ever since. I'm guessing they will have had some more with the same fault by now, so it should be easier to report.

Nikon D2Xs NEF not working with Aperture

This is so shocking. I should have researched more..... but I cannot believe that Nikon and Apple do not have it together on Aperture??
I just switched from the Canon 1DS, which worked like a charm with Aperture, to the Nikon D2Xs and Apertrue will not support NEF files from the camera. Frankly. I am pretty stunned. What's the deal? I find a lot of chatter in the forums about other Nikon model NEFs that are not working.
Since there are only 2 serious top of the line pro-digital SLR manufacturers out there, I would have thought that they would both be supported fully.
Nikon Tech support said that their plug-in developer kit has been available for a long time, it is up to Apple to take advantage of it.
Am I out of line here - ranting on..
Does anyone know of a solution to this issue, other than dumping Aperture and moving to Nikon's Capture NX (when they get to finally release it) and Photoshop?
Many thanks for you help in advance,
NIck

So you switched from Canon to Nikon. I decided to do
the switch vice versa. What were your reasons to pick
Nikon?
The EOS and the D2x are both very excellent cameras. Some things I find better with the D2x:
Image quality.
First off, as far as I know prints from Canon's best and Nikon's best are similarly excellent. In spite of the EOS's ~50% higher cost and additional pixels it does not provide significantly better prints. Nikon worked some pretty good engineering to achieve that.
Price.
Most photography involves price tradeoffs with faster/better lenses, etc. costing more. In the case of the D2x the arguably equal and in some ways better camera actually costs $thousands less.
Speed.
The D2x shoots RAW at 5 to 8 fps versus the EOS 4 fps. When you are trying to capture the "perfect" instant of a rapidly changing scene higher frame rates increase the likelihood of catching the perfect moment. Or if you are auto-bracketing, faster speed captures your bracketed images before the scene changes. The concept of shooting a burst of 5-20 frames just to catch the very best pic is new to most photogs, because with film it was impractical. With cameras like these DSLRs new photo workflows may evolve. [Edit: My workflow has evolved. I now shoot almost all dynamic shots and many group shots as a burst of 2-5 pix at 2-5 fps.]
8 fps Crop Mode.
The D2x will shoot 6 megapixel images taken from the center of the frame at 8 fps. So if one wants to shoot tele action shots like sports it is ideal.
Buffer capacity.
IMO a much bigger issue than fast frame rate is the buffer capacity at that fast frame rate. The D2x captures about twice as many pix (~22) as the EOS does before the buffer fills.
Card capacity.
Canon built a slower camera with 30% more pixels and that leads to less images per card, slower file transfers, etc.
LCD size.
The D2x LCD is more than 50% larger than the EOS. The larger LCD changes everything as far as the ergonomics of DSLR workflow are concerned. Just try a D2x side-by-side against the much smaller EOS LCD.
Exposure Compensation (used constantly in DSLR workflows).
+/- 5 EV for the Nikon versus +/- 3 EV for the Canon.
Weight.
Being a 200# male with large hands I don't worry about size and weight too much. The Canon does weigh almost a pound more. Dimensions are pretty similar, with the Nikon a few mm larger. If size/weight are issues the Nikon D70s and Canon 20D are much smaller but sacrifice pro features like good viewfinders.
Self-timer.
Nikon has choice of 2/5/10/20 seconds whereas Canon is only 2 or 20 seconds. I find 2 seconds is sometimes not enough to let the camera settle down on the tripod if it is extended, so typically I use 5 seconds. Using 20 seconds as a cable shutter release substitute would drive me crazy. Often this is moot because I almost always have a cable shutter release with me.
Framing.
Some folks prefer a DSLR to be the same lens factor as 35mm film. Other folks do not. Quality superwide lenses are achieved at a $500-$1500 cost while supertelephoto is a $5000-$15000 cost; personally I prefer the 1.5 factor since it extends the expensive telephoto range. However, 1:1 versus 1:1.5 is a matter of personal preference rather than one being "better" unless print quality were to suffer.
The high end EOS does beat the Nikon D2x hands down in lower noise at ISOs of 800 and above. I am not familar with the high ISO performance of the D2xs, however.

My DL and UL speed so slow! What is it supposed to be?

It takes me over 4 hrs to download a single 700mb movie, This is crazy! When my mother lived 2 houses down I used her wifif and it took me 20 minutes TOPS.
My best speed I ever got was a download speed of 1.05 Mbps and my upload speed of 0.29 Mbps
Keep in mind this was the BEST speed I got and I tried over 50 times today. I usually don't even get a 1 in download speed and my upload speed 99% of the time is 0.20Mbps
I just don't know what I'm paying for? This is the reason why I never pay my bill in full because I feel like I'm getting ripped off. I could of sworn I was promised a 2.00 Mbps speed but I don't even come close to that.
I have regular Verion DSL (FIOS not available in my area)
Should I just dump Veriozn with this kind of speed? I heard Comcast maybe buying Charter Cable and that's my only other option. I can't get Charter Internet right now because I'm fighting them..It's a boring story it's basically someone lived in my apartment 8 years ago or even more and they had the same last name of me so Charter won;t give me service until I pay this persons bill and I'm not paying someones bill i don't even know..
So anyways is this kind of speed normal? Is this what people pay for? It seems kind of lame to pay this much for this kind of speed honeslty. I bet this speed is not far off from the old AOL dial up speed!

Please check MyVerizon or your bill for the name of the package you pay for, and report back. Verizon has two plans for DSL: High Speed Internet and High Speed Internet Enhanced. The first package offers speeds reaching a maximum of 1Mbps down, 384kbps up. The second package is supposed to offer anything with a maximum of 15Mbps down, 1Mbps up.
In addition, please report what DSL modem/gateway you are currently using, along with what router you have in use. I'd like to pull your modem's Transceiver Statistics so we can get an idea of how good the line is.
Given that ADSL is a technology that is slowly becoming the new dial-up, it's no surprise you're asking the question about how fast it is supposed to be. Generally, I moan and complain about anything less than 5Mbps when working on someone's computer. If the FCC has their way, "Broadband" may soon be defined as 24Mbps, something ADSL2+ really cannot deliver. The only thing capable of those speeds over a single line are VDSL/VDSL2, Fiber, and Coaxial/DOCSIS service. VDSL/VDSL2 is extremely distance limited - typically past 5,000ft out, it's useless for very fast speeds and ADSL2 makes more sense.

Onboard Wait On High Speed Capture

I would like for an onboard program to wait for a high speed capture signal from a trigger input. Unfortunately, I have not had success with the flex_wait_on_condition function; it has always timed out before detecting the event. However, calls to the function flex_read_hs_cap_status identify that the high speed capture line is indeed toggling faster than the 3 second timeout. I use the following sequence of functions to configure the high speed capture:
flex_configure_hs_capture(m_BoardID, NIMC_AXIS2, NIMC_HS_LOW_TO_HIGH_EDGE, 0);
flex_begin_store(m_BoardID, ProgramNumber);
flex_enable_hs_capture(m_BoardID, NIMC_AXIS2, NIMC_TRUE);
flex_wait_on_condition(m_BoardID, NIMC_AXIS2, NIMC_WAIT, NIMC_CONDITION_HIGH_SPEED_CAPTURE, 0, 0,
NIMC_MATCH_ANY, 30, 0);
flex_end_store(m_BoardID, ProgramNumber);
Axis 2 is configured as a open loop stepper axis with encoder resource 2 mapped to it.
Any thoughts as to why this wouldn't work?
Thanks!

Thanks for the suggestion. It seems to work fairly well, although there is some delay between the trigger event and the execution of the critical section of code.
Are you aware of a method to speed up execution of an on-board program? The critical section of code in the attached program fragment takes about 4ms to execute. With the added delay of the polled high speed capture line, I am limited to a ~150 Hz loop. I would like to increase the execution time by about twice.
Also, a command from the host computer seems to preempt the on-board program, causing it to take up to ten times as long to complete. Is there a way to set the priority of the on-board program task above host communication?
Thanks for you assistance,
Mike

HT3180 I owned an Apple tv and after upgrade my internet to higher speed my Apple Tv does not work the only message that show on the screen said if time and dates are not found go to apple/support/tv tried almost everything and nothing. Please somebody

I owned an Apple Tv and since I upgrade my internet to higher speed my Apple Tv does not work. Please someone help.

In most scenarios you shouldn't need to forward ports, however if you need to, you may be best contacting your ISP.
As with most router issues, I would recommend that you contact your ISP with details of your problem (assuming that it was your ISP that provided it to you).
There are simply too many manufacturers with different software features and settings and often different names for such features and settings, that the best advice will likely come from those that are knowledgeable about your particular router.
Make sure your router/computer allows access over the following ports
