Buffalo Forums

   

I have a Linkstation EZ 500GB LS-L500GL connected through a Netgear WNR854T RangeMax Next Wireless-N Router Gigabit Edition.  I have one PC hardwired to the router, and 2 wireless laptops.  All three computers run Kaspersky.

 

I am on my second Linkstation.  The first one worked great for about 2 weeks, plugged it in, installed the software and all 3 computers worked flawlessly.  At about 2 weeks, it disconnected from all 3 computers at the same time.  The only way to reconnect is to unplug the power and ethernet cable, then plug back in, which 50% of the time does not work, the other 50% of the time may work anywhere from a few minutes to 1 day.  I cannot map the network drive upon finding out it has disconnected - I have to unplug/reboot first.  Buffalo had me send it back for a new one.

 

The new one worked for 2 or 3 days before disconnecting all over again in the same exact manner.   

 

This is driving me nuts.  I am a beginner in regards to anything other than simple fixes.  Your help is greatly appreciated, and I apologize if this solution is on another thread that I didn't see.

 

Go to buffalotech.com

under support you will find the download section.

 

from here you can download the new firmware 

   

Thank you.  I downloaded the update, then unplugged/rebooted the Linkstation so the updater could find the unit.  It is currently still connected, however I don't know if that is due to the reboot or the firmware update.

 

I'll monitor it over the next few days and give an update.

 

Thank you for your help.

   This morning at 5am, the Linkstation did it's scheduled backup (through SyncBack), then for whatever reason shut off.  It's back on now and connected.  Will continue to monitor and report back.

   

having the same problem as of yesterday; unit in service only about two weeks.

i'll try the firmware update as well.

It sounds like there's something else going on. Check different power outlets, and try resetting the device to defaults.

   

Update - I left it alone for a couple of weeks.  Last week pulled the plug, reboot, and it has been working flawlessly over 2 computers for the past week.  This has happened before where it works for a couple week stretch then stops, so I'll keep you updated.

   

firmware updater reported i already have the latest firmware which i confirmed on my linkstation's admin screen - 1.02 ...

but following a hunch i had earlier, i've set the power from Auto to On and
haven't had problems today connecting/reconnecting.

   This may sound really newbie, but how do I switch the power from auto to on?

Some of the buffalo devices have an auto/manual switch in the back.

   

Mine has only power button, reset, and a "lock" icon.

 

what is the model number and firmware version that you have?

   

It's the Linkstation EZ 500gb NAS.  I have the most updated firmware.

 

Ironically this morning my scheduled sync did not happen....the network drive cannot be found.  I'll have to do another unplug/reboot.  Very annoying.

 

   

it may sound like a network issue, pulling ip via dhcp.  2 weeks sounds like the ip lease expires and is released.  try assigning the ip manually, using the ip it received when you first installed the software.  it may also fix the syncing issue if the backup software is configured by ip and not my device name.

 

doesnt hurt to try, please post what happens

I am having the same problem with my LS-WX1.0TL/1D.  It seems to disconnect from the network after about an hour, and the only way to get it back on is to reset the power.  I have a static IP address assigned, so not getting a DHCP lease should not be a problem.   The problem happens with Windows XP Pro, Vista, and Windows 7, so it's not an OS issue.  Also, when the linkstation is in this state it does not respond with the NAS Navigator 2, nor does it respond when I point my brower directly to it's IP address.  The linkstation is about 2 months old, and while I cannot be certain, I think the problem just started happning.  It't connected to my network via a Cisco switch and is running firmware version 1.30.  I thought about upgrading to the latest, but the release notes do not mention anything about this problem, so I am holding off on the firmware for now.

 

Any suggestions would be greatly appreciated.

I am also having the same problem with my LS-WX1.0TL/1D, however, I can ping it.  When I can connect and log into the management screen, I see that there is a fan hard drive error.  This unit is less than a year old.  This is the second Buffalo product I purchased, the 1st one was retired due to errors pointing to also a fan problem.  Is there a solution for this or do I need to go and buy a new system, different vendor?

additional info:

 

Firmware @ 1.37

Running static IP and have changed IP

I'm having the same issue of network connectivity dropping.  I have the latest firmware as well.

 

Should the switch on the back be in the ON or AUTO possition? I have it set to ON and have for 2 weeks and the problem has been happening since we purchased the unit.

 

Thank you.

Auto is used if you have installed their software.

 

I done with Buffalo products.  Two strikes not waiting for three.

I have an HD-H250LAN which has started randomly disconnecting from the network, sometimes after only a few minutes, sometimes after an hour or two. Removing the LAN cable and reconnecting usually (but not always) fixes it, for a short while.

I thought the cable might be faulty, but I've swapped that out to no effect, and I also tried a different port on my router, to no effect.

However, I think I've now fixed it....   My model has a LAN cable cross-over switch on the back of it (later models do not, I believe). I think this switch might have got some dirt/dust in it, so I switched it back and forth a few times, to clean the contacts on the switch, and now it all seems to be ok!
