Hi,
Do you know which lights ? Are they capslock and nunlock ? If Yes, please try a hard reset and see if it works.
1. Power off your laptop
2. Remove the a/c adapter, battery and everything that is attached to your laptop.
3. Hold the 'POWER 'button down on your laptop for about 10 seconds.
4. Plug in the a/c power supply (without battery) and power on.
Regards.

HELP ME Please ! No Blue Lights on both of my WRTU54G-TM Routers behind a WRT54GX2 Router

I've had this configuration installed and working for the past two months as such:
Motorola Cable Modem - COX Cable ISP - 15Mbps down / 5Mbps up ; actual rated is higher on speedtest.net
Linksys Router - WRT54GX2 (I'll refer to this as main Router)
Linksys T-Mobile Router - WRTU54G-TM - with 2 SIM cards (this is VOIP router 2 for two lines)
Linksys T-Mobile Router - WRTU54G-TM - with 1 SIM card (this is VOIP router 1 for one line)
Network Topology:
Main Router:     192.168.2.1    router mode ; DHCP ON; Wireless ON - SSID: alpha
VOIP Router 2:  192.168.2.2   bridged mode; DHCP off; Wireless ON - SSID: beta
VOIP Router 1: 192.168.2.3   bridged mode; DHCP off: Wireless off
Both VOIP Routers connected from Internet Port on Router to LAN port on a 10/100 switch
All of this was working fine for the past two months, it even survived some Southern California power outages and came back with flying colors; UNTIL YESTERDAY...... VOIP Router 1 blue light ceased in the morning - Troubleshot it myself and then with tmobile/Linksys and verdict was a defective modem. VOIP Router 2 was still going strong UNTIL I decided to power cycle it to see if that would help with VOIP Router 1; well the blue lights never came back on; To make a long story short - after pulling my hair out and talking to tmobile/Linksys again; I was able to get the blue lights to come on both VOIP Router 1 and VOIP Router 2 if I connected one of them directly to the cable modem and the other VOIP Router  2 directly to VOIP Router 1.  I also did a hard reset on both VOIP routers back to factory defaults (did this before as well). Now, I can't even have a switch between VOIP ROUTER 1 and 2 and get a blue light on the second one. What in the world could be causing this, does anyone have a clue?
Now you may ask why do I need it setup like I had it originally, Cable Modem is downstairs ; Main Router downstairs was in place to isolate the Network from the VOIP Routers in case I needed to reboot the VOIP routers - which I had to do a few times in those two months. So I still had Internet access in the house when I rebooted the VOIP routers. I also wanted my phones upstairs, not downstairs and that is where the VOIP routers were situated.
I've searched thru this forum and googled elsewhere, but haven't found any solutions that work.
So can anybody help ????? TIA

OK, Here's an UPDATE, I believe that I have found a firmware bug in the WRTU54G-TM v1.00.21 code.
In order to get the blue lights on two WRTU54G-TM Routers, VPN - IPSEC passthru must be enabled on the 1st Router, or else the blue lights will not come on the 2nd Router.
fyi... I have 3 sim cards in the 2 Routers for 3 phone lines, 1 Sim card slot is empty.
I reset both WRTU54G-TM Routers to factory default and plugged one directly in to the cable modem and the second WRTU54G-TM into the first. I rebooted the cable modem and routers in order and in a few minutes, I had 3 blue lights for voice on the routers (YES!). Ok, so now I tried reconfiguring the Routers the way I want them. I only need wireless on one of them, not both, so I turn off the wireless on the first router, I also disable all 3 VPN passthrough options on both routers and disable the firewall on the 2nd router. Now I lose the blue lights on the 2nd Router. Well after some troubleshooting, I have found that the IPSEC VPN passthru option MUST be enabled on the 1st Router to get the blue lights on the 2nd Router. I have reproduced this very easily by disabling the IPSEC on the first Router and the blue lights will go off on the 2nd Router - I have to re-enable the IPSEC on the 1st router and reboot the 2nd Router for the blue lights to come back on the 2nd Router.

My ZEN 8GB always have that blue light glowi

I just installed it and was upadting everything. Now I did the Firmware update last and at the end, it said ''Rebooting player...'', I did saw my player close but never re-opened again. I waited 5 minutes. Screen still black and it has the blue light glowing like if it was charging even thought I fully charged it. Now the problem is my computer can't no longer detected it. But I can't turn on my player. I removed the USB cable and still has the blue light glowing. I can't do absolutely nothing with my player except staring at he blue light and the black screen. Help please.Message Edited by SimonMK on 2--200707:4 PM

I pushed the Reset button. It did close my player but when I turn it on, I see the Creative and ZEN title but it goes back to a black screen and has that blue light glowing again. I thought the battery were over so I reset it again. And plug it in my computer. My player automatically turn on and do the same thing. It doesn't recharge the battery since I see no icon of the battery on the screen.

Pearl won't boot up with blue light?

I have a pearl and last night the screen went dead and the blue light turned on.
I have taken the battery out and as soon as I replace the battery, the blue light comes on. Doesn't even attempt to boot.
Any ideas?

Blue light means bluetooth connection is established. That's strange.

Ipad 2 screen randomly gone blank shows dark blue light up but no apple logo upon restart and remains the same.

Hey
So I left my Ipad 2 on charge and it was working absolutely fine. Later on when I came in the room to check up on it, it had a blank screen and the Ipad was lit in the background as it was giving off the dark blue light but nothing on the screen would come up. I tried shutting it down using the power button and the home button yet nothing. Even the Apple logo would not appear. I just recently upgraded to IOS 6. I'm not sure what exactly caused this as it was working fine just a few hours ago. I've tried connecting to itunes held down the power and home button nothing seems to be working. Also I no longer have the warrenty.
Not sure what to do now

Perform a Reset... Try again...
Reset ( No Data will be Lost )
Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Release the Buttons.

WRE54G after reset only 1 blue light, no activity light

I have spent a lot of frustrating hours trying to setup my newly bought expander WRE54G.
Issues:
1. I could not find my expander by typing 192.168.1.240
2. So, I tried one of the reset tips I found here, by holding the reset button for 30 seconds, unplug it while pressing down reset, wait 15 secs, while holding reset and turn on power again, and then wait further 10 seconds.
3. After having tried this, when I turn it on, there is only one blue light on the link button, no light on the activity, and I could not see my expander at all on the wifi network. (A normal reset would give me a red light on the link & a blue flashing light on the activity, and I was able to see my expander on the network)
Is there any way to undo what I did with the reset tip? I really want to restore it to factory defaults.
My WRE54G does not say whether it is V1 or V2, so I guess it is V1?
Anyone please help!!!

Did you ever get this issue resolved? I am having the same issue.

WRE54G Disconnects; Red Light Comes Back On Hours After Seeing 2 Blue Lights

Does anyone have a fix for this problem? My WRE54G shows 2 blue lights, works fine, but within a few hours it disconnects and one red light shows. This forces me to unplug and then plug back in the WRE54G, and reboot my computer.
What is causing this intermittant failure? How do I eliminate this?
Message Edited by buntaro on 04-09-200710:34 PM

Since I did not have any responses to my query, I engaged a Linksys tech in an email chat session last Friday afternoon to have a go at the problem. Essentially he walked me through the usual diagnostics, device firmware version levels, etc., and I would be happy to send you a copy of that session if you think it would be of help to you (just agree to ignore my typo's!).
For reference, I am running the following configuration:
- Two Dell PC's each running XP with all current patches applied.
- Full Linksys wireless network with their WRT54GL, V1.1 router, the WRE54G range expander, a WPSM5G USB print server (connected to a Brother MFC 820CW printer), and an SB5120 Motorola cable modem.
- All Linksys devices are at current firmware levels.
- Secured network (WPA-Personal):
After the chat session, I made the following changes:
- Re-installed the expander firmware...just in case (my idea).
- Found my remote PC set to work on wireless "B" or "G" and changed it to match my router on "G" only (this was my error as I intended to run "G" only throughout).
- Changed the router and expander from channel 6 to channel 11 (the tech recommended that I "try" channel 1 or 11).
So far (knock on wood), my expander has remained "on" (2 blue lights) even through a short commercial power failure this afternoon).
Hope this helps a bit...best of luck!

6300 Blue Lights

Hi all
Yes my issue is with the blue lights on the side of the phone.
I have gone through every individual setting/profile and put it to lights off.
I have ensured I have no unread/unopened/unlistened to messages/voice mails. To the extent that I deleted every message sent, received, delivered, both text and voice.
Yet those blue lights stay on and constant. They obviously show up more in the dark which is annoying.
Anyone know how I can switch the side lights off please?
Thanks

Hi, May i suggest the follows:
- Reboot the phone: switch it off, remove the back cover and take the battery, the sim card and MMC out for a while (5-10 mins). Try again later
- Back up your personal data (especially ur contacts), then proceed for factory settings : Menu > Settings > Restore factory settings > Security code (12345 by default)
- As last step, check the profile settings : Menu > Settings > Profile > General > Personalise > Light effects > Off
Hope the above helps

Zen 2GB - a blue light is flicker

Hello,
first of all, please excuse my bad english. Unfortunately there is no german board.
I've bought an Zen 2GB and have watched the following: Sometimes the screen flickers in a blue light and turns off after about one second. Remarkable is, that when it happens the player is not in use, for example the player is laying on the table and is turned off. This flickering effect also happens, when I plug in an earphone. But it doesn't happen with every earphone (only some models, I've tested) and only in about 80 percent of the times, when I plug it in.
Recently I've exchanged the player at my local dealer. But the new one still shows the same effect.
My question now: Has anyone made the same experience with his Zen and is the Zen not ok?
I would be glad for your answers.
Bernd

I also encountered this same behavior when using a different headphone for my ZEN 4GB...sometimes it restarts, sometimes it totally hangs up..leaving only the blue light on... I cannot turn it off... I have to do a reset on the thing which forced me to bring along a hair pin everyday... I think it has something to do with the antenna incorporated in the headphone slot...any other idea what's causing this?Message Edited by daywalkerz on 02-2-200809:4 PM

WRTU54G-TM Internet / Blue-light & XP SP3 Issues

So I've been wrestling with getting the WRTU54G-TM maintain a constant internet and "blue light" connection now for over a month. I thought I had finally stabilized the situation (downloaded the set-up wizard from the Linksys site, as others recommended) and used that to set up the router, and everything seemed to be rock solid for a week or so.
Then I installed both iTunes 8 (which installs the new version of the Bonjour service) and XP Service Pack 3 in the same weekend, and now the WRTU54G-TM gets flaky every time I turn on my computer (it's fine when the computer is off).
At first I thought it was the Apple Bonjour application, but after un-installing that, the WRTU54G-TM was still flaky. I then upgraded the router to the latest firmware version (v1.00.09), but still no luck. The router will lose the internet connection (and the blue light), and after a few minutes the connection will come back and the blue light will come back a few minutes after that (at least no power cycle is needed).
So I'm left wondering if XP SP3 is what is now causing the problem and is doing something to mess with the router connectivity.
Does anyone know of SP3 issues with the WRTU54G-TM and how to resolve these?
Thanks!
Ian

I did a little bit more research and found that XP SP3 is indeed causing a number of routers to crash and reboot (which is what I'm experiencing when my computer is on).
Apparently there is some issue involving DCHP and "Option 43" which can cause some routers to reboot. There's more information and a hotfix here http://support.microsoft.com/kb/953761 which I'm going to try tonight (crossing my fingers) and hopefully it will solve the problem...

ATV, 5.1 and a Sony Receiver......no blue light!?!

First and foremost, what a fun couple of days. What a great forum too! So many knowledgeable folks willing to share their know-how.
So, my question is this, anyone else out there with their aTV hooked-up to a Sony receiver that's not getting the blue-light on the main display to indicate true 5.1?
Maybe I'm worrying needlessly here as perhaps the audio signal will only be a true 5.1 when HD content is rented. Last night I watched a few of the HD Trailers and was kinda expecting to get the blue-light during those trailers. But nope, it did seem to be pretty decent sound quality, but it almost seemed like it was a "fake" 5.1. Dunno though. Also, I did have a couple issues of "buffering" while I was watching the trailers. The trailer would load completely with the blue bar filling completely and then during the play of the trailer it would suddenly stop and the bar would have to fill again. But it did fill much more quickly (say five seconds or so).
Also, under Audio Settings, I DO have the Dolby Digital Out set to ON. (I'm using component and optical(Toslink) cables for the hook-up. My preference is always HDMI but that's not possible here as I only have two HDMI inputs on my Panny plasma and I'm using them for my HD Cable box and Sony PS3.
The new UI for aTV is not baaaad, but could've been so much better. I actually think that the UI from the prior version was much more visually pleasing with those large, sharp, flying eye-catching graphics. I don't know if Sony would throw a hissy-fit or not, but the aTV should adopt a UI menu like that of the PS3 where the icons are stretched horizontally on the display with the user then being able to scroll up or down within that icon to access that sub-menu. IMHO, that would be much cleaner and more visually pleasing.
And on a sidenote and for clarification, one does not need AirTunes to be able to control their aTV from iTunes on their PC. I was under the impression that I wouldn't have the option to do this as I don't have AirTunes or Airport Extreme. I was VERY happy to see the COMPUTER button on the bottom right part of my iTunes giving me that control. I now won't have to change the input on my HD display to access the UI(thusly disrupting whoever's watching a program pm the TV) to change tunes. (I might've misunderstood some of the recent posts on this though. Maybe what was actually being inferred was that an aTV only need to be AirTunes "capable" to do this.)
Geez Phil, ramble much? lol
Carry on.

Hi Drum_Phil,
I'm not near my ATV right now, but I checked out Superbad on the iTunes page, and it doesn't mention anything about 5.1. (Many of the HD movies have 5.1; some don't.)
Does it say that it's in 5.1 on the ATV rental page? If not, even though it is in HD, it may just be in stereo.
Hi Maggot.
Thanks for checking that for me. According to iTunes +through my aTV+, Superbad is not only in HD, but also in DD (with the official DD logo).
Another forum poster (RichSolNuv) has confirmed that this movie did indeed support true 5.1 when he watched it with his Sony receiver. So it's probably just a matter of dialing in the settings on it and/or my aTV.
Thanks for the props on my handle. I love lexical ambiguity.

What is wrong with apple tv when the blue light flashes quickly

I am having trouble with my apple tv device. The blue light flashes continuously and will not reset at all.

Welcome to the Apple Community.
You might try restarting the Apple TV by removing ALL the cables for 30 seconds.

HT3964 my computer displays only a blue light on the screen after booting (and rebooting)! How can I fix this?

There is a blue light on the screen of my mac book pro and the computer will not display anything! Does anyone have any advice/recommendations!?

For Safari you could try clearing its cache and history via Settings > Safari.
For Safari and your other apps you could close them all completely and then see if they work when you re-open them : from the home screen (i.e. not with any app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of each app to close them, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
