WRT1900AC - WiFi on 5GHz band RANDOM REBOOTS

I've noticed that this router is totally unstable (random reboots) on 5GHz band.
I'm using Lenovo ThinkPad T440p with build-in Intel(R) Dual Band Wireless-AC 7260 and it's unusable on 5GHz band using Mixed mode. I've setup to N-Only but it doesn't help, router reboots randomly while i'm surffing web.
Now i'm only using 2.4GHz band so router doesn't reboot at random.
Linksys please fix this issues!!!! this shouldn't happen on 300$ router!!!!
I'm running lastest 1.1.8.161917 FW

Was a Factory Reset performed before and after any firmware updates then set up from scratch?
Was the router working before any firmware updates?

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
I've been using Mixed Mode on 5Ghz with my router and haven't had any issues. Possible envrionment or configuration issue or incompatibility issue with the ThinkPad....Please give feedback on question presented...lets see if we can find the problem.

Iphone6 ,ios 8.2,8.3 randomly reboot with blue screen

i have an 64G iphone 6 with ios8.3 .my problem is blue screen!I had it before this update too but now is intorable! sometime my wifi drop and it randomly reboot And sometimes it shows blue screen and randomly reboot ;i think it is beacuse a software bug.
It happen 4 or 5 times a day! I think im not alone ,also my friend have this problem on iPad Air2.

Exactly the same issue with iphone 5s 64G. It started with iOS 8.2 and then 8.3.

Could wifi with a university network drop often because of a 5ghz band connection?

Hey guys,
I've been having wifi issues at my school/work (same location) with the connection dropping randomly. It seems to happen several times an hour. I purchased a MBA months ago and had no problems with wifi connectivity till recently. My school has acquired a new access point in the facility. It was right around the release of Mavericks. So now I've become unclear on whether it's the network or the new OS. Anyways, the network is WPA 2 enterprise with dual-band connectivity. This past week I have done my fair share of studying on dual-band technology and now understand perks and downfalls to 2.4ghz versus 5ghz bands. That reading was due to a connection issue at home. However, today I finally realized that I was connected to the 5ghz band at work/school by using the option key and clicking the wifi icon. After browsing through several forums, I was still unsure if A) the 5ghz band was responsible for wifi dropping, and B) Whether or not I could disable the wifi from defaulting to the 5ghz and use 2.4ghz as a solution instead.
Since I could not find answers to those two questions I have tried the following...
I changed the MTU to "1453" since it's the so-called "magic number" for mac's. And yes, so far it is the magic number because the wifi has not dropped once since applying it. I'm still standing by, convinced it will drop. Wireless diagnostics is currently monitoring if it does. Typically I use the ethernet adapter so I don't have to worry about any of this. That's a fix, but not the one I'm looking for. It's flat out annoying! I know I can try renewing the DHCP lease as well. I haven't done it yet because I'm seeing if the MTU was the sole source of the problem. I've already performed basic troubleshooting and like usual it didn't solve anything. That's not to say that restarting doesn't cover a higher percentage of issues!
Honestly the MTU change could be the end of my problems, but I'd still like some insight on my two questions in the first paragraph. Any guidance is strongly appreciated. I've been loving my mac and the community since I made the switch not too long ago. I'm just still familiarizing myself with everything. Thanks in advance for any help!

That's correct.
When it's unable to obtain an IP address from a DHCP server, machines are supposed to self-assign themselves an address from the 169.254.x.x range.
This is so that you can, for example, connect two machines with an Ethernet cable or via Wi-Fi without the need for a DHCP server and the two machines will be able to talk to each other.
(If you care, you can read the technical details here.)
So the big question here is why your machine is failing to obtain an address via DHCP, and it sounds like an issue with the DHCP servers on your network.
If you want to read more than you probably would ever want to know about how one campus is dealing with similar issues, you can here.)

Guys help, random reboot + wifi drop on startup

I got my preordered tablet Z I love it! first day as im installing apps, the thing just randomly reboots on me! ever since that time, eveytime I turn this thing on, it connects to my wifi at first, then drops the connection,waits 2 mins and connects again..my xperia z phone nor my ipad does the same weird thing..
anyone else had this problem??

Did you try a repair by PC Companion ?
Maybe something went wrong and messed with the system when installing apps ?
Tell me if the PCC repair doesn't work.

Mid 2012 MacBook Air Troubles (Random Reboots & No Camera)

Hello, I'm hoping somebody can help me out. I have a mid 2012 Apple MacBook air that I am having problems with. Ever since I bought this laptop from my friend, it has randomly rebooted during sleep mode, and the FaceTime camera has not worked. I was told that water has been spilled on it at one point, but I have went over the entire computer and do not see any sort of damage. Because I was not having any luck getting it to quit the rebooting, and because the camera would not work, I purchased a replacement motherboard and battery.
The new parts arrived today, and I quickly installed them. I was instantly having the same exact problems. The computer will still reboot when I close the lid to put it in sleep mode. It instantly starts rebooting after about 2 to 3 minutes. And it will continue to reboot over and over until I reopen the lid. In addition the camera is still not detected, and I have double checked under the system properties that it is not showing up under the USB tab. I have cleared the PRAM & SMC, still no changes. As a last ditch effort, I decided to reinstall OSX 10.9 Mavericks as a fresh install. No go...
Does anyone have any ideas of what I can do to get this thing running properly? I bought it because I wanted to use it for some home-video editing, and in its current condition I don't feel that it is trustworthy. The only things left that I can replace, would be the display or the thunderbolt daughterboard. I already previously had replaced the SSD with a larger 256 GB, and I tried swapping out the wifi card as well. I'm banging my head against the wall here, and really want to be able to use this computer. Any help would be greatly appreciated!

Unless you get the answer you need here, I would contact Apple MacBook Air Support or an Apple-Authorized Service Provider for service.
Apple Service Technicians have access to all special tools, test equipment, parts, and proprietary data needed for efficient repairs. If cost is your issue, you can ask for an estimate before they proceed with any needed repairs.

Yosemite random reboots on macbook mid 2012

Well I've read thoroughly all the posts related to this kind of issue and it seems it affects a wide range of devices. Either mac minis or 2011 macbooks and so on.
I would like to explain my experience and ask for any advice available. I am experienced with computers and OS's, even though I would not call myself an expert, but as an engineer I possess a certain amount of knowledge. So there it goes.
TL;DR at the bottom
Macbook pro mid 2012 13". Default 4gb memory installed, I added a Samsung EVO 830 SSD in 2012 when I bought it, never had any problems with it.
After a couple of weeks after upgrading to yosemite (november '14) I started noticing the macbook resting on login screen after a reboot. No crash report, no message visible of any reason. As I was installing some special software to do some work related to a lab I was working at the time, I thought it was software related. MS Word and Excel often crashed and I had a couple of problems with other programs. Then it started doing it while I was working, so I decided to check things out. The system freezed for some seconds - 1-2 minutes and proceeded to reboot. Sometimes a hard reset had to be performed.
I decided to perform different installations with different options in order to identify the problem:
Reinstall Yosemite from recovery mode: same result, random reboot, no specific app in use, either Xcode, Safari, or just resting idle with just finder.
Format disk and install yosemite applying time machine backup: same result, random reboot, no specific app, and so on.
Format disk and clean install, manually installing the same main software installed previously: same result, random freezes and reboots.
Format disk and clean install, manually installing essential apps (mac app store only): same result, exactly the same result.
Always with the latest OS version available, and with TRIM enabled and disabled, to discard issues with it. PRAM and SMC resets all along.
During all the testing, the console has not shown any crash report or kernel panic related to the event. After every reboot, console would not show anything special before the boot_time line.
After looking for solutions on different forums, I noticed a pattern on some cases that implied a wake on lan or a handoff, or wifi issue. I tested on different networks, disabled and enabled all options commented, with no effect.
Entering
syslog -k Sender kernel -k Message CSeq 'n Cause: -' | tail | awk '/:/{$4=""; print}'
on terminal 90% of the time returned errors -128, and some -112 or -2, but they would not be logged to every freeze, just some of them. By the time the
As they may indicate a hardware error, I decided to proceed with the warranty.I bought the Applecare extension when I bought the computer (expiring this summer) so I talked to Applecare about the issue. As there is not an official Apple Store in my town they pointed me to an ASP in my city. They noted all the issues I commented above, gave me a case number to deliver to the ASP so they would have all the information.
I brought the computer to the ASP, gave them the case number (which they totally ignored, the employee seemed oblivious to what a "case number" was) and expected them to find the error. As I noticed the freeze could be sometimes forced via waking up the laptop, I made them a demo. I had ran already the apple hardware test and any hardware tests I was aware of. Etrecheck came out without issues or anything worth mentioning, so I thought they might have specific apple tools to identify hardware error.
They told me they could not find any error on the computer, but that they found errors in the SSD, swapped it with one of theirs to test and no issues found. Good, I thought, at least they found the issue even though all tests run on the SSD by me did not show any trace of it. They charged me 25€ for the service as the SSD was not part of the original computer. As I had been experiencing issues for some time I did not care. I asked them for some kind of report to check the error to provide to the SSD manufacturer, Samsung, as they offer 3-year warranty on SSD's and it had not yet expired. The report said "errors in disk", plain and simple, I asked to talk to the technician for extra info, but he could not remember if it was "corrupted sectors" or something else.
Contacted Samsung, sent my SSD in, and in 4 days I had a new (refurb maybe) SSD same model same size at my door. During those 4 days I reinstalled my old original HDD. As it had a few miles on it (using it as external disk) it was really slow and sometimes it would freeze but the whole system was always dragging, so it could be also failing. Worth mentioning that when swapping disks I noticed the ASP had messed up the position of the small screws on the back of the computer. They did not seem to know there are 4 shouldered screws and 3 regular ones.
I put the new or refurb SSD in, clean install and do some testings. First day everything ok. Proceed to install software. Seems ok. After a couple of days the first freeze and reboot appears. After a couple of PRAM and SMC zaps, events seem to be reduced to a minimum. Even though the system is not completely stable, and I am not quite satisfied with the uncertainty of the freezes (in the middle of a presentation is not the best moment to have one), as it's freezing 1-3 times per week I consider it reasonable.
Time goes on, freezes start to appear again. Sometimes while booting, sometimes on login screen, sometimes on heavy usage sometimes on idle. I still follow all threads related to similar issues, in case a fix appears. All sleep / wake / wifi on - off on sleep tests have been performed.
Now the issue seems to be reduced to two kind of events: random freezes and reboots, and errors while booting. None, and I mean zero of the reboots or freezes has ever had a .crash or any system diagnostic reports related to the hour or even date when the freezes took place. EVER.
While booting, it crashes and I have to hard reset 2-3 times. When freezing, 30% of the time it does not reboot, and gets warmer than idle state but cooler than under heavy load.
I usually zap pram and smc and then it boots normally. But I should not have to be doing that every time I turn it on.
I know its a long post, but it's something I have been following for 5 months now. It's not that I am unaware of different options to solve it. Zapping seems to be the way to go, but still the random freezes interrupt workflow and provoke loss of data.
TL;DR: same freeze and reboots as other people. No discrete GPU to relate it to. Default memory installed, SSD model working on 10.8 and 10.9 with zero issues. All software installation combinations tested. ZERO crash reports on console related to the hour or date of the events. Shutdown causes negative codes, ASP cannot find the issue.
Considering bringing it to Genius Bar, but undermines the purpose of a ASP and if they got the same tools they will not find the issue either.
Appelcare expires in June. Any options I am unaware of? I would relate it to the specific model of SSD under Yosemite if I was the only one experiencing freezes and reboots, which I am not.
Thanks you

Boot into Safe Mode. If the problem ceases then you need to remove Virtual Box and the software that installed com.bluecoat.kext.bckd 4.4.1f20. If this does not fix the problem then make a Genius Appointment and take it in for service.

Early 2011 MBP 13 random reboots (no Kernel Panic logged)

Hi,
Problem Description:
My MacBook Pro randomly reboots at least 1-2 times a day. I cannot find a kernel log because each restart is a double one.
Let me explain the problem further : 1. Im doing something (nothing specific..no specific app) on the mac 2. The screen freezes and becomes unresponsive ( I know a reboot is coming)
3. I get the gray screen which says "Your computer restarted because of a problem..." ...this is followed by the white screen with the apple sign..it loads for a few seconds and it reboots AGAIN..this time i hear the chime...loads into the OS normally ...works until i either shut it down / put it to sleep / another random restart (varies from 1 hour to 6 hours )
Things I've tried :
SMC / PRAM reset
Erase Drive and TimeMachine Restore
Apple Hardware Tests / Diagnostics all pass
Verify / Repair permissions / disk (did this a million times)
Reindexed Spotlight
Erased Drive and did a clean install and MIGRATED files from TimeMachine
Safe Mode ( THIS did not have random reboots...also fyi ..i didn't try this for long)
Logs Data:
Since I don't have the .panic files. I am pasting a chunk of the log before and after the PROBLEM.

MacBook Pro 13 (MBP 8,1 random restarts)

3GS randomly reboots after 5.0.1 (WDT timeout)

Hi all,
I have since a few months a 3GS which was in 4.x, and never had any problem of any kind.
I upgraded to 5.0.0 when this released was issued, no problems while upgrading, and although I noticed my battery lasted less, I had no major issue.
When 5.0.1 was released, I was happy to notice it addressed some battery issues, so I quickly updated my 3GS.
Since the first 5.0.1 I experienced 3 to 5 minutes constant hard reboots, ie after 3 to 5 minutes, even while doing nothing, the iphone powersoff and on (apple logo) and reboots, forever. (battery charge was >85%)
If I removed the sim, or put the phone in airplane mode, the reboots disappear.
I then tried a restore from iTunes, thinking an app may be the problem, and after the restore, I had no single reboot ... for 3 days !
One afternoon, It started rebooting every 1 to 1h30 hours...it did so 5 times that day. And after these 5 times, no single reboot for 3 another days.
Last night, to try some battery tests, I let it drop to 5% battery charge, and switched off, then switched on. Since then, 3 minutes systematic reboots.
I had to put it on airplane mode to prevent this.
I noticed the reboot always causes a "panic.plist" log in the event logs, which error is a WDT timeout (the log enumerates tens of processes and is truncated...)
The number of applications in use at the moment is not changing the behaviour, I can have 20 open apps or nothing, the phone reboots.
I'll try another restore, but seems a weird issue, with the carrier or when the phone tries to hangup on a cell..
If someone has any clue ?..

I also having exactly the same problem as what you described (panic with wdt timeout....) The reboot seems to be random. Airplane mode with wifi on is okay (no reboot).
However, I noticed I have this problem 2 days ago while I still using ios 5.0. Then I install 5.0.1 and restore my data from icloud backup. I did not get any reboot while the phone slowly restore my 1000+ photos from icloud until it completed 900+ photos. Then it start to crash again and again and again. Now, I swtiched to airplane mode and it seems to be okay. However, we should be able to make/receive a call with iphone, right? It's not ipod touch.
I'm from Thailand. Carrier is AIS. Nothing to do with Orange. My phone is 3gs unlock.

Does the iPhone 4S support the 5GHz band?

While the iPhone 4 supported 803.11(n), it did so only on the 2.4GHz band. I can't find any information about this for the 4S. Does anyone know if it supports the 5Ghz band?
Sorry....I asked too quickly. The answer is NO. See http://www.apple.com/iphone/specs.html

I wan't to use my 5ghz wifi on my iPhone 4S but it can't see the SSID for my 5ghz network. The specs page for the iPhone 4S states it uses:
802.11a/b/g/n Wi-Fi (802.11n 2.4GHz and 5GHz).
No, it does not state that.
The 4S does not have the 5GHz radio.

Linksys WRT400N - Unable to Connect to 5GHz Band

Good Evening -
I am on my last nerve regarding my situation and I am hoping someone on this board can help me in some way, some form. My Linksys WRT400N router is not under warranty anymore so I can't receive any assistance through Linksys.
I have a Dell Vostro 3400 running Windows 7 Professional 64-bit. The wireless card in the Vostro is a DW1520 Wireless-N Half-Mini Card. This card can operate in the 2.4 GHz and 5 GHz band spectrum. Obviously, the Linksys WRT400N is a dual-band router and broadcasts in the 2.4 GHZ and 5GHz band simultaneously.
I originally had a DW1501 Wireless-N Half-Mini Card. Apparently, there was a known issue with this card with regards to connecting to a 5GHz frequency. With the DW1501 I was never able to connect to the 5GHz band ,,, the card would "see" the 5GHz band but it would never be able to connect to it. While on a support call with Dell wireless, they admitted that the DW1501 has an issue with actually connecting ("seeing") to a 5GHz band.
Dell offered to replace the DW1501 card with the DW1520. So, now my Dell Vostro has a DW1520 and it is able to "see" the 2.4GHz and the 5GHz bands. I am actually able to connect at 130 Mbps on the 2.4GHz band which is better than what I was connecting at ... which had been 65 Mbps. Now, the DW1520 card can also "see" the 5GHz band AND it can actually "connect" to the 5GHz band. When I "connect", I connect anywhere between 170 and 243Mbps, or thereabouts. So all is good until I actually open a browser and try and surf the net. When I do this, nothing happens ... it's like I am connected to the Internet but not really. So then I have to disconnect from the 5GHz and connect back the the 2.4 GHz band.
I spent nearly 2 hrs. on the phone this afternoon with another Dell technician trying to find out why I could connect to the 5GHz band but not actually surf the Internet via a browser. After 2hrs, the Dell technician could not find a resolution. However, we have possibly narrowed it down to the Linksys WRT400N router. At this point, I no idea what the issue is. The Dell technician said that I may have to re-install Windows 7 Pro 64-bit. I totally disagree. I have downloaded all recent DW1520 drivers and the Linksys WRT400N has the one and only firmware version. The Dell tech also recommended "resetting" the Linksys WRT400N. I have not done this yet ... but will.
So ... I don't know what else to do or where to turn. Is there a setting in my Linksys WRT400N router that I am not aware of that will allow me to connect to the 5GHz band? I have disabled my MacAfee firewall ... nothing. I have checked over everything I can think of ... I have researched the Internet for the optimal settings for the Linksys WRT400N. I have made those changes. Nothing. I don't have any IP address populated within the Wireless MAC filter settings within the Linksys WRT400N. I have done the ipconfig steps and have "refreshed" and "renewed" the ip addresses.
What leads me to believe that there is something not set correctly with my Linksys WRT400N (or maybe it's my AT&T Siemens modem that provides the gateway to the Internet) is that I am seeing the EXACT same issue that a state above with my Dell Precision M4400 Mobile Workstation laptop. That has a Intel WiFi 5300 ABGN network card in it. Same thing ... it actually connects to the 5GHz band, but I can't surf the net.
Finally, when I go to the Linksys WRT400N setup page and I go to Wireless > Wireless Basic Setup and change the Network Mode for the 5GHz band from Mixed to Wireless-A Only, I can actually connect to the 5GHz band but only at 54Mbps.
So, I am at a loss. I am not sure what to do, where to look or turn, nor what to or what not to configure. Any advice on optimal network settings or anything regarding this post would be greatly appreciated. This is like buying a nice sports car and not being able to get out of second gear. What's the use?
Thank you in advance.

Most likely the router. you said that 2 different laptops have the same EXACT problem. Try this (in order): Reflash the firmware, reset the router then reconfigure the wireless settings. Set the channel width and channels to AUTO.

E8350 5GHZ Band and Macbook Pro

I saw another thread like this but really this should be brought to Linksys attention. The 5GHZ band is extremely slow with my Macbook Pro Retina (2012). It takes around 30 seconds to load any webpage if it loads at all. No other device has a problem and my macbook works with every other router at 5GHZ. The 2.4GHZ works fine. The strange thing is, the problem even happens when going straight to the router to make changes in the menu, not even outside the local network. It will take 30+ seconds to load any page in the router settings (sometimes it doesn't load at all). Oddly enough, it will load the login page instantly, anything other than that takes forever. The wifi networks aren't overlapping channels with each other, or my neighbors either. Any help would be appreciated.

Can not see 5GHz band on my network

My HP 200 Quad all in one PC can not see the 5GHz band on my network. It works fine on the 2.4GHz band and I have another PC on the network that is able to see the 5GHz band. My wireless card is a Ralink and according to its properties it should operate on the 5GHz band on channels36-161. HP Tech support wants to charge me to fix this and the unit is 3 weeks old and was like this right out of the box, not to mention my 2 year warrnty. Can anyone help?

When I check the wireless device properties it list the 5 GHz band to operate through channels 36-161 and also states the device is working
properly. The last I checked my router it was broadcasting on channel 36, so everything seems to be fine but I can not receive the signal.
Hello FWV, Sorry for the confusion. I was under the impression that you could not connect at 5 ghz. Now you suggest you cannot connect at all.
Can you advise if the Ralink can connect to the wireless router at the 2.4 ghz frequency, or not connect at all?
Can you advise if you can see the router on the network at the 2.4 ghz.?
Many times, you may need to reboot the router to allow it to recognize new connections.
Just not sure of what is going on. Maybe some other Member can be of more help.

I want to operate on the 5ghz band with my wireless router. on my HP Pavillion dm4 1160us

I have a:
HP Pavillion dm4 1160us laptop
Intel WiFi Link 1000 bgn internal network card
Windows 7 Professional 64 bit operating sys
Netgear n600 WNDR 3800-100nas (Premium Edition) wireless router
It operates fine on the 2.4 ghz band as it should but Id like to replace the network card with a dual band card to operate on the 5ghz band at up to 300 or 450 mbps.
What are my options

I have been told in the past by people of varying degrees of knowledge, that I cant just change out the card.
Is this true? Do I need to go into Bios??.
Thanks
Dave
That's correct, this is why I posted the link to a service guide for the laptop. The card is listed in the manual so no BIOS modding is necessary. There are 2 compatible adapters but Intel is better than Broadcom..

Random reboots K8T Neo2 and 3200+

I am still getting the random reboots. I have noticed the most reboots when having alot of windows open in my web browser, both firefox and maxthon. I have done full virus scan and run both adaware and spybot with no change. Right now I am using 1 windows with my browser and no problem. I can also play games that have high system requirements, AAO and BF2 neither causes any problems. Anyone have a answer or clue to what is happening? Core center says my cpu temp is running what I call wide 37-51 degrees. The fan speed changes alot also. Is there a way to lock the fan speed and still use core center? I don't remeber but think my Intel and 865PE Neo2 setup the fan speed stayed constant.
Thanks

IPhone 6 random rebooting, running iOS 8.1.1

Hi this is driving me crazy. I just had the new phone for about 3 weeks, and now its failing on me. the random reboot become more frequent every single day. the first random reboot was right after i installed the newest update iOS 8.1.1, before then i encountered none of the rebooting problem. Now it reboot after about 30 mins of use, which is annoying, and it won't restart until you plug it to a computer and run iTunes.
Plz tell me whats going on here and provide me with some valid way to fix it.
Thanks

Hi Brain thanks for your reply but i'm using a mac to sync my music files. i tried your tactic before but it did not work for me. I know everything could sync over wifi but the thing is it won't even open to let me put my passwords in. It was stuck at the apple logo while it go darker and bigger then flash back to a brighter and small apple logo.
I previously owned an iPhone 5s and it was updated till ios 8.1, everything is fine on that one. I also read other threads about how the older phone's backup may crash the phone, so I'm trying to set up as a new phone now.
Thanks again for your reply and help!
