is it possible to back up to an external hdd via usb or eSATA ?
I have difficulties getting the DLNA to work.
The NAS is working fine on the network. I have activated DLNA and specificed the /service/DLNA folder.
My TV is a Samsung LE40A8661W which has DLNA built-in.
The TV can find the DLNA servers on my PC, but cannot find the LG NAS DLNA.
I hope someone can help me?
I didn't have to do anything but enable DLNA and the PS3 picked it up and plays Video great.
You have a network and the TV plugged into the network?
Do you also have files in the /service/DLNA folder?
Both the NAS and the TV are cabled to the router(Belkin).
I have pictures in the folder, and also a subfolder with more pictures.
I beleive the problem is in finding the LG NAS, because it is not shown in the TV's source list at all, as is my computer.
Could it be a problem with some settings in the router?
Could be a TV setting.
Have you powered the NAS off and and back on after changing the DLNA setting?
Try and google your TV with DLNA in the search and see if anything comes up.
EDIT: Found something on google that might help you...

This sure got my attention.
And why is their no comments regarding:
1) Transfer speed (MB/s) of the NAS across 100Mb/1000Mb. This is a NAS!!!! The primary function of it is to serve files across the network !!!!!!
2) Network Transfer speeds with multiple accesses (multiple users). is it good, bad, horrible? Does it affect playback of Hi Definition files from DLNA/Upnp server, and what bitrates are the tested files 40Mb/s, 50Mb/s, 10Mb/s ?
3) Where is the power consumption of this unit? Will it be better to buy a Good server case with an Intel Atom with nvidia Ion/Ion2 platform, and have more expandability with more drives?
4) Can I map NAS drives/folders in Windows/Linux/Mac without installing software - software often grants only a single user license ..... so installing this software to map drives on more than 1 PC violates the EULA turning people into pirates!
5) Does it support Jumbo Frames?
6) Does it do NFS?
7) What partition formats does it recognize for external storage drives plugged into it - NTFS/ Fat32/ EXT2-3-4?
8) What formats does the DLNA server support? Does it support the PS3/Xbox360, and what formats are picked up by this unit?
9) How much ram/cache does it have? What are the HDD's that come with it? What speed (RPM) are the drives? Did the author try any other drives, and did it makes any difference?
10) Does it support multi-user? Can folders be assigned different security levels for different users, and how customisable is this?
11) Were there any problems noticed with the networking? Any file aborts, slowdowns - etc/etc.
12) When transferring files from USB - HDD, what's the speed, is it quick & easy?
13) What's the internal transfer speeds - HDD to HDD?
14) Can I replace the ODD with another ODD - Can it be another manufacturer's Drive? Can I retrofit a BDRE drive into the DVDRW version of the NAS?
15) Upgrading HDD's -> What partition/file-system format are the HDD's? This is particularly relevant if the system breaks down, can we just throw together a Windows/Linux PC, and start sharing these drives, or are they some sort of proprietary format? Which OS must be used? Is it an easy process to upgrade these drives? How flimsy are the connectors, are the drives easy to remove?
16) Can the Esata/USB be used simultaneously? How do you access these on the network? Can these be mounted on an existing directory on the Mounted HDD's? Are there any limitations to the recognized file system formats (ie, limited to Fat32/4GB file sizes?)
17) HDD power/spin-down settings?
18) DDNS support? Can I access this unit from a WAN/internet?
Who's ever heard of a NAS with an optical drive? That's a bonus to a NAS, and not the primary function. This review totally misses the point of a NAS!!!
I now find myself in the position that after this review, I'm looking for OTHER reviews to get the information I want.
The reviews I read for my current NAS, I bought about 2-3years ago, I read about 10 reviews, along with a few weeks of user opinions, and the reviews generally had less pictures, and alot more pages.
At any rate, the no# of reviews available for this unit is pretty small, so the rate of uptake for this NAS is pretty low, so I'd expect it's a low-end consumer grade NAS with a gimmick, and it can't compete with the big boys of the NAS world.

How can you do a review on a gigabit NAS without testing it with gigabit ethernet?

Hibernate mode further reduces power draw down to around 6W. Hibernate mode can be terminated by web access with administrator credentials or from the front panel.

There's relatively little control available, however. You can't for example, set user storage quotas.

To set up remote access, you enable the DDNS feature and enter in a user name and password. This creates a sub-domain on lgnas.com. Oddly, if you disable DDNS for some reason, you can't re-enable it with the name you originally used - you must create a new name.
In my testing, I found that setting up the service or even going to the remote access page often resulted in a "loading" icon that occasionally timed out. Ultimately, I was able to configure the DDNS setting, and the page showed the correct public IP address for my network as shown in Figure 6. |
Miscellaneous note: Single drive NAS performance is limited to approximately 67MB/s for single drive NAS configurations and <100MB/s for professional raid setups. Generally, commercially available NAS setups are limited to 17-25MB/s (read) for single drive configurations, and 30-50MB/s for performance raid configurations.
By comparison, a Windows XP (pro) PC to Windows XP (pro) PC transfer from the server (using a realtek network chipset) resulted in 18MB/s transfer speed for reading, and 10-12MB/s writing speed across a gigabit network link. (2.5GB file tested using XXCOPY with a mapped network drive).
Similarly, various flavours of linux result in hitting the single drive 17MB/s read (9MB/s write) in server (realtek onboard nic) to Windows XP (pro) PC. (2.5GB File Tested using XXCOPY with a mapped network drive).
To be tested is intel Nic's which actually have a network processor onboard, compared to marvell & realtek, where all network activities are done in software (CPU) which can greatly increase network throughput.
Anecdotal evidence suggests that realtek peak at 30MB/s transfer speeds, Marvell achieve 35MB/s, whereas an intel card will achieve upto 55MB/s in the same setup.
Samsung and LG Tech support have not been able to figure this out so far. Does anyone have any clues to true DLNA compatiblity?
Thanks,

The DLNA works perfect through the PS3, plays most AVI and MKV I have tried as well as MP3.

This is truely a great unit will all the bells and whistles. I've gotten all features to work consistently, except for DLNA. My Samsung LNB46 HDTV sees all my other DLNA sources except the LG-NAS (firmware: 2450). My WDTV Live and a small iPOD app sees the LG-NAS OK.

Firstly I have had loads of issues with the NAS printer freezing and then when it restarts it keeps printing the same document over and over. I have tried cancelling all documents yet it seems to ignore this command. It's driving me nuts and I have had to unplug the printer from the network as I ccan't seem to stop it.
When I click on the 'file viewer' button it opens up ajaXplorer and not the LG software window that you show in your review picture. Why is this?
I have upgraded the firmware to 1.0.0_2450 so is this casuing the problem?

Has anyone gotten other software to recognize the bluray drive and burn BD's with it?
My printer though I had connected to another PC and not the NAS.
|
I am using a netgear wpn 824 wireless router. The printer is a canon pixma mp780 and it is plugged directly into the back of the n2b1 via the usb port. I think I am going to have to uninstall the printer from the network completely and reset the n2b1 to solve this issue. Do you have the ajaXpress software loading when you click on the lg file viewer?

A few months after posting the review I had gotten a PS3 and Panasonic 42" Plasma.
The DLNA works perfect through the PS3, plays most AVI and MKV I have tried as well as MP3. |
The PS3 doesn't support MKV, unless the NAS is repackaging it as a m2ts or similar.
I didn't realise NAS mobs were getting involved in transcoding .....
I also us PS3 media server from my computer and I don't have to use any of the encoding options to play them.
|
When you say no Wireless LAN support, does that mean this NAS can't be access wirelessly on your network?
|
You will need a wireless Access Point, or a Wireless Router to get the wireless clients to connect onto the wired network, and hence the wired NAS.
What is the native file format for the device? I see it supports various formats but is the device OS linux based etc?
I have 2 1TB drives that I used with my NSLU2 (EXT3 format) but it's time to upgrade. I would like understand compatability with installing used drives and file/folder permissions etc.
I would like to avoid formatting the drives or having to play with permissions etc if possible. From the looks of the device it seems to all be there but this is something which I don't think is covered or perhaps I've overlooked..
Thanks.
regards, Sotos
Also, I've noticed that using the web interface on the NAS, you can only set permissions for the top level folders. I cannot seem to figure out how to add nestled folders and set permissions for those folders as well....
Any help would be appreciated.
Cordially, Mike
I'm not saying this the case for LG NAS, but normally you would need to add a user group and then add a user to that group, then set permissions. Then adding folders to that group should allow it to be browsed and maintained in Windows explorer.
If anyone has a clue on what I need to do please let me know.
Also, what is the advantage of using the iTunes server vs. just creating a folder on the NAS and mapping a drive on your PC to that folder and pointing iTunes there?? That is what we did on my last NAS for 6 years and it worked just fine.
Is it easily compatible to read a Blu-ray data disk on my Windows 7 PC that was burned on the NAS? and vice versa? My main usage would be for computer data backups.
