Good luck in your endeavours.

That's absolutely true, but after sales service is often the most important thing, and D Link should have made an effort with me to rectify the problem considering how many times I had to RMA the DAP-1533, but they didn't, so they've lost me as a customer.

Here, this will take care of any router/DAP heat issues:

I was looking into getting the DAP-1533, but was curious if the thermal issue had been fixed in production Or should I avoid it and find a different one? I'm no stranger to modifying things, but I prefer not to buy something that requires it to function properly.

[FurryNutz]

Do you still have your DIR-857?

What wireless modes are you looking to use? Bridge or AP?

It's unfortuneate that the heat sink isn't affixed to the chip fully. I bought a 1533 new in box off ebay a few months ago cheap and it had the same issue. I don't know how old the 1533 was though.

We believe thats the only problem. After doing the mod, the DAP is very stable. 

I agree, you shouldn't have to mod any thing to make it work right. The DAP works right out of the box, it's when under heavy load after we presume over time that the problem will present itself, since the heat sink isn't fixed to the chip good enough, that the DAP will begin to fail.

It's a shame too, other than this issue, it's a great companion to the 857 router. I took mine with me last year for xmas holiday travel and used it as a bridge with my 868L for playing xbox. Works great.

Let us know what WiFi modes your looking to use in a DAP and we can recommend something. There are a few solutions out there...maybe consider a slightly Moded DAP-1533? Hehe.

I am still using my DIR-857... and love it 

I plan to use it as a Bridge. I want to setup my home theater better (receiver, bluray, smart TV, xbox). I also have aspirations of setting up a media center so I can access all my dvd's from anywhere on my network. Those are all stored as .vob files on a TVIX 6620 right now, but really want something better.

That said, my family is streaming more and more content and I'm just trying to optimize my setup. I'd love to run a hard line, but I can't (yet  ). I tried the powerline product... that didn't work worth a lick. So I figured I'd try the DAP-1533. Worst case is i get an AP out of the deal... or a burnt out 1533 

P.S. Thanks for the quick response.

[FurryNutz]

Hmmm...well depending if your looking to use the 1533 as a bridge and I presume if your going to connect just those devices to the 1533, that would work. I would recommend running a wired when you can. What is the distance the bridge would be from the 857?

Also there is a mod for the 857 as well... 

If your family seems to be streaming more media via WiFi, you may need to get a better WiFi AP to help handle the streaming load.

One suggestion, kind of extreme however in your case, maybe beneficial...Install 2 DIR-868L or 865Ls on the back end of the 857. Use one as the new main Wired AP for both 2.4 and 5Ghz. Turn OFF the 857s WiFi radios. Please the 2nd DIR as a bridge for the media LAN devices. This would bring better streaming handling for those WiFi devices and you'd have a bigger bridge pipe for the heavier .vob file streaming and such from the wired media devices connected to the bridge.

I tested this out a while back with my 865L and 868L. They are the only ones that could stream raw BD files with out buffering during playback. VOB files wouldn't see any glitches at all. BD files are much more data intensive so I did see some minor bufferings during play back. I tried same files on 5Ghz N mode on the 857 and the BF files are just too big for N mode to handle. Even at 450Mb WiFi Speed. VOB files were good and seamless in play back.

Since you seeing more streaming in the family and want better performance, I would recommend using AC mode for any bridging and streaming to those wired devices for seamless playback while other stuff maybe going on.

What is this TVIX device? NAS or some media server? I just got into a DNS NAS device earlier this year. I moved all my media files off a Windows 7x32 File server PC to the NAS. While I didn't really see alot of issues while using the File Server, having the NAS now simplifies things more. I have 1x2Tb drive thats just for raw BD and VOB files thats rotating. It lets loaded and when everyones done viewing, files are deleted. Any VOB favorites get burned to disk. I haven't entered into the BD burning world yet and for the most part, don't see a need to at this point.

Also if you don't have one already, ensure you use a external Gb network switch in between the 857 and all other devices. This helps especially when streaming between the client and the media server source and eliminates having to go thru the router which isn't needed.
Some suggestions to review and think about.

Let us know your price point...the 1533 could still be an option as well...I found mine last nite. 

Let us know what you think...

Just to add:

If you want a stronger hold, you'd need to use Epoxy like originally mentioned or this non-conductive adhesive:

[FurryNutz]

Thanks MotherFo, Ya I presume the Arctic Silver would be good...For Horizontal DAPs...when in Vertical, user s needs to apply some forum of glue to keep the new heat sinks for sliding off.

My Wifi connection itself is pretty good. I like to use InSSider to measure that.

I'm my living room... where the wifi is used the most, my connection hovers around -50 to -54 dbm (5 ghz). If I switch to the 2.4 ghz, it's typically -36 to -40 dbm.

When I'm right next to the DIR-857, 5 ghz is -32 dbm and 2.4 is -24 dbm.

Firmware 1.04 QoS Mod?? I was looking at that the other day. I might try that out.

Thanks for the feedback on the 2 DIR-868... but I don't think I'll go that route.

A TVIX 6620 is a Media player/center and tuner in one. I needed a tuner for my Projector... and wanted a media player/server so it worked out. That was a few years back. I also have a DNS-323, but that thing is so old, it just doesn't perform well compared to today's standards. I still use it... but for file storage and backups (not media).

Good note on the Gb switch... I have a couple of them.

I think I might try the DAP-1533, it seems like it would be worth trying. I can get some heat sinks from work 

Thanks.

[FurryNutz]

No there is a heat sink mod for the 857 and 827 routers which I was referring too.

If your ISP uplink speed is less that 2Mb then the QoS mod is not recommended. You can give it a try if you want too...Thats not official FW and is not supported by D-Link.

There is a new un-opened DAP-1533 on ebay...

Let us know what you get...

[motherfo]

Ceramique should hold. It is generally stickier.  Regular Arctic Silver would probably slide off.

[FurryNutz]

I can hear the clink of the sinks falling off now. (Shuddering at the thought)

Well, another DAP 1533 just bit the dust on me (the one I originally installed the thermal upgrade on that I used to start this thread).  All the ethernet ports went dead again - same symptoms as the first four that bricked themselves.  I was streaming HD via my AppleTV when the DAP 1533 decided that it had enough and decided it wasn't going to work anymore...

Furry - you are welcome to my bricked DAP-1533 if either you or DLink want to examine it...  Just let me know.  And this time, only the ethernet ports failed - I can still connect to the DAP 1533 via wireless to check configuration and status.  Interesting...  Seems the problem lies in the ethernet portion of the circuitry.  The RF pieces and the controller (WEB services and other CPU functions) seem to work...

The marketplace now seems to have a number of other 5Ghz media bridge / extender combo units available.  I have just started streaming with a NetGear WN2500RP (which can be configured for bridge mode only operation).  So far so good.  It won't do 450mbps (as advertised for the DAP1533), BUT it might survive longer in service than does the DAP1533.

[FurryNutz]

Dang...This was in Bridge mode? I presume the switch to AP mode the LAN ports are still hosed?

I've asked D-Link if they'd like to inspect the unit. I'll let you know. Sorry it failed again.

Was there a heat sink on the LAN port switch chip? I know there was one chip that got hot that I believe I put a heat sink on as well.

Hi Furry,  To answer your questions about my newly bricked DAP 1533:

1. My DAP 1533 was operating in bridge mode when it decided not to work and it was in the middle of streaming HD Video through my Apple TV.  I only use bridge mode.  I had three devices connected to the ethernet ports: an SMART LG TV, a SMART Sony Blu-ray player, and an Apple TV media player.  Now all four ethernet ports are "dead".  I tested each port using a laptop computer and the response I get from MS Windows when I plug in an ethernet cable and enable the wired port is "Ethernet cable unplugged".  As I said, the RF circuitry and the controller (WEB services and other CPU functions) in the DAP 1533 continue to work.  I can still wirelessly connect to it to interrogate status and set configuration.  Only the ethernet LAN ports failed.

2. When switching to AP mode and re-doing the wired ethernet cable test, I get the same result - "Ethernet cable unplugged" on all four ethernet ports.

3. Yes, I did have a heat-sink glued onto the ethernet chip that originally ran very hot.  I guess my heatsink upgrade wasn't good enough!  I'm not sure what it would take to "fix" this problem short of redesigning the circuitry (probably using a different ethernet chip).  Is DAP-1533v2 hardware a possibility or is this product at end-of-life (with D-Link simply walking away from the problem)?

Next steps?
