Connecting WLC to 6509 Core ... Connectivity Issues

Hi,
I have all four ports of a 4404 WLC connected to a 6509 via fiber cables. However, I am not able to ping the WLC or see it.
I have a couple questions about this ... First, if I want to do LAG it is necessary that all ports are active and plugged in, correct?
Second, in the switch config, to my knowledge all ports should be trunk ports, however the customer has configured them as "switchport trunk encapsulation isl" instead of "switchport trunk encapsulation dot1q" ... does this matter? I have never used the isl command so I am really wondering if this is supported in the WLC?
Any help would be greatly appreciated!
Thanks!

You can do it either way. I do not use Lag currently on my 4402 controllers, instead, I use two ap-managment interfaces.
Yes, etherchannel reference = portchannel

Connectivity issues for random phones in CUCM 8.6 on Vmware

I have a client that has problems with around half of there ip phones (6921 & 7945) after a situation with overheating in the serverroom.
The solutions was a 1 Publisher, 1 subscriber setup with each on a separate Vmware server.
The Publisher is connected to the Core Switch which is further connected to 4 distribution switches which again connect to 5 more distribution switches. They have around 200 ip phones connected to these switches that get assigned IP's with DHCP.
The physical disk that the Subscriber was on was destroyed the incident. The Publisher they recovered, but to do this they had to recreate the vm descriptor file and attach it to the flat-file.
So the current situation is that the system is running with only 1 Publisher and no Subscriber.
There is also a license warning in the CCM Admin section, stating a License Overage (2 nodes used, but only 1 licensed.)
The license status is not invalid though, and the license state is "Uploaded". This second node I suppose might be the Subscirber that no longer exists? The phones have more than enough licenses.
When powered up the system seems to run as it should, but only about half the phones have connectivity to and can register with CUCM.
I have tried to reboot some phones remotely by cutting the power on the switch interfaces where they are attached, but that made no difference.
The console log on the phones that are down show TFTP Timeout & File Transfer Error.
The phones that are up and running can be pinged successfully from the CUCM cli, but when pinging the others I get "Destination Host Unreachable".
The strange thing is that it seems completely random as to what phones are up or down. On all switches there are connected phones with both working and non-working connections to CUCM.
To try to pinpoint the fault I chose 2 devices on the same switch and compared the config for each interface, one that has connectivity and is registered, and one that does not have connectivity and is unreachable.
Everything seems to be identical so I can't see what causes this error on the one, but not on the other.
Also when I ping the ip phone with no connectivity to CUCM from any of the switches, the ping is successful.
Anyone know what could be the cause of this behaviour?

Hello and thank you for your time.
The phones get there IP’s from a DHCP Server (Not the built in one in CUCM, but an external server). I have tested that the DHCP process works by powering off a phone (one of the phones with connectivity issues), deleting the lease, and then powering the phone back on and seeing the device request and receive a new lease.
There is only one CCM group active and both servers are in this group with the Publisher as highest priority server. All phones are in the same Device Pool attached to this group.
There are a lot of warnings regarding dbReplication & missing node due to the subscriber being gone. Also there is an issue with NTP server (see below). I will post more on this tomorrow morning.
I have also attached the console log from one of the phones that can't register.

IChat video connection issue, not related to router

I received a brand new 20" iMac Core 2 Duo just yesterday and intended to use iChat AV to video conference with my girlfriend, who has a 12" iBook G4 1.2GHz with an iSight and all system software up-to-date.
We both have DSL connections at home. We also both have wireless routers. The very first time we tried a video conference, it worked perfectly without a hiccup and everything just looked and sounded wonderful. At the time, she was connected wirelessly and I was connected both wirelessly and through Ethernet to my router's local network.
The second time we tried it (only a few hours later), seemingly without having changed any settings, it failed to work, and hasn't worked since. At first, we would get Error -22, saying something about how bandwidth is insufficient to maintain a video conference. However, I do not believe bandwidth is the real issue since all other network/internet tasks on both ends are spiffy as usual. We also both tried turning off Airport and just connecting through Ethernet to our routers' local network. Same problem.
To then determine if the problem was with one our routers, we both set them aside and plugged our DSL modems directly into our computers and connected to the internet with PPPoE. This appears to partially fix the problem: we are able to initiate a video conference, we both have audio, I can see her, but she can't see me; sort of a one-sided conference. On my screen, the image of myself freezes as soon as the conference is initiated. So unless I'm missing something, the ultimate cause of this problem doesn't appear to be the routers.
You can bet I tried a bunch of the common tips mentioned in this discussion forum before posting this question, such as changing the iChat port in the preferences, turning off Firewalls in the Sharing preferences and changing Quicktime streaming speed.
In summary, it worked once and hasn't worked since, and routers do not appear to be the cause of the issue. Does anyone have any further advice for me? Any help would be greatly appreciated! Thanks.
iMac 20" Intel Core 2 Duo 2.16GHz Mac OS X (10.4.7)

First off I want to thank James for his willingness to help me test connections today. James has suggested I check into upping my Mother's connection. I will definitely look into that.
I wanted to update the thread that I tried the three test accounts at Apple (appleu3test01-3) and had success from all three on my home computer via my wireless configuration no less. This is what stumps me about my connection issues with my Mother - we can both connect to others but between us we get error -8's since iChat 3. I also find it odd that this is happening even though we are both Earthlink customers - I would chalk it up to routing tables or something if we were on different ISP's.

Troubleshoot connectivity issues Outlook Anywhere - Exchange 2013

Hi there,
As part of our Exchange 2010 -> 2013 migration we've transitioned CAS to Exchange 2013 2 weeks ago. Some 50 mailboxes have been moved to exchange 2013. Moving mailboxes for everyone is scheduled the 2nd week of july . Because our current version of Outlook
is 2007 (migration to 2013 is due thissummer) we've configured NTLM authentication for OA.
Exchange setup: 8 Multirole (CAS/MBX) virtual (VMware) Servers: each 4 cores, 24 Gb memory (reserved) : Windows 2012 SP1, Exchange 2013 SP1 (15.0.847.4030)
Right now we're facing client connectivity issue's: Outlook Anywhere clients are continiously losing connection with exchange, some people (outllook 2007/exc. 2007) report every minute or worse.... Moving the mailboxes of affected people results in
less problems: Sometimes no disconnects for 10 to 30 minutes, then reconnects every minute for some time.
We've already set the timeout for the oa-pool in our network proxy (riverbed steelapp) to 20 minutes and the minimum keep alive on the 2013 servers to 120 seconds which improved Oultook 2013 clients; before I experienced reconnects every minute, after every
10 to 30 minutes (with periods of reconnects every minute)
testconnectivity.microsoft.com gives positive results (apart from a nspi warning about server side encryption)
testing with rpcping according to
http://blogs.technet.com/b/exchange/archive/2008/06/20/3405633.aspx gives some interesting results:
I've tested all (8) CAS 2013 servers over ports 6001, 6002 and 6003; each 100 rpcpings with a for loop: every response was either about 500 ms or about 21 Seconds ?!?
How can we furher troubleshoot the reason of the long reply time. Eventlogs (and SCOM with exchange 2013 MP) show no relevant events or alerts.

I've repeated above test this afternoon: All test resulted in about 40-60 (of 100) replies >20 seconds

We've changed a timeout setting in the Steelapp virtual server (old: 10 sec; new: disabled) the connections between Outlook and Exchange are, when established, very stable (almost no failed request anymore)
However there still existst a conectivity issue:
The 8 Exchange 2013 servers are placed in 2 different Active Directory sites (4 servers in each site) and I have found that a cross site rpcping consequently takes more than 20 seconds (with the loadbalancer bypassed ! !) where a rpcping on the
same AD-site takes 200-300 miliseconds...
rpcping -t ncacn_http -o RpcProxy=Host-in-site-A -P "user,domain,password" -H 2 -F 3 -a connect -u 10 -v 3 -s RpcProxy=Host-in-site-B -I "user,domain,password" -e 6001 => 20+ seconds
rpcping -t ncacn_http -o RpcProxy=Host-in-site-A -P "user,domain,password" -H 2 -F 3 -a connect -u 10 -v 3 -s RpcProxy=Host-in-site-A -I "user,domain,password" -e 6001 => 200 miliseconds
rpcping -t ncacn_http -o RpcProxy=Host-in-site-B -P "user,domain,password" -H 2 -F 3 -a connect -u 10 -v 3 -s RpcProxy=Host-in-site-B -I "user,domain,password" -e 6001 => 200 miliseconds
rpcping -t ncacn_http -o RpcProxy=Host-in-site-B -P "user,domain,password" -H 2 -F 3 -a connect -u 10 -v 3 -s RpcProxy=Host-in-site-A -I "user,domain,password" -e 6001 => 20+ seconds
The same tests with our Exchange 2010 CAS and MBX (NO multirole) shows fast (300 ms.) with every combination. The servers are both on the same networks in each site
We've already started talking with the network guy's: There should be no rules between both networks.
OWA, Autodiscover, EAS all work fine.
How or where to troubleshoot this slow response between two AD site's ??

Wireless Connectivity Issue with 802.11n.

We have a 5508 Controller and sixteen 1142 APs.
Several of our laptops were experiencing connectivity issues over Wireless. Older laptops that do not support 11n are not having any problems.
I disabled 802.11n for both 'a' and 'b/g' in the Controller. Now the newer laptops connect with no issues.
They would in fact connect to the APs while 11n was available, just no Internet Access - (cannot ping DG, etc). Disabling/Enabling the laptop WL adapter would allow brief access (sometimes), but they'd quickly lose Internet Access once again.
Our WLANs are configured for WPA2/AES.
This looks like a 802.11n configuration issue at either the Controller or the Laptops (or both). Both are using the Default settings for 801.11n.
Any recommendations for correcting this? Are there best practice guidelines for configuring 802.11n?
Thanks.

Wireless Lan connection issue with Linux clients

Hi
In a large Wireless Lan enviroment for a university, we have 3 WISM moduls attached on a 6k hw - Manged by ACS v6.0.181.0
We recently upgraded the software version of the controllers from 4.x to 7.0.98.0 - the Emergency Image version is 5.2.157.0
Since then, the students with Linux clients have massive connection issue - repeated connection lost in a short time period.
However the students with Windows clients have no problem at all.
The studends report, that their linux clients getting so much of some kind of unnecessary broadcast traffic which can not be handled by the NIC - and the NIC goes down - and this happens all 5-10 minutes.
Affected Linux clients are: Ubuntu v10.10 - also OpenSuse, Fedora and Arch-linx with latest OS version.
Any Idea how I could solve this problem?
Thanks in advance for your help

Hi Nicolas
Thanks for your reply. The broadcast forwarding is disabled on WLC's.
Pls find below the attached picture, which shows the captured broadcast traffic on a linux client (sent by a student to me).
I'm not sure, if its really only the broadcast traffic, which the linux clients can not handle.
From my point of view, it seems also to be that the linux clients are somehow disadvantaged among the other clients like windows or mac, if they all trying to get a wireless connection.
But the fact is only the linux clients are affected - and this happens to the linux clients only in our wireless infrastructure.
Windows or Mac clients have no such problem at all
regards
Enis

Help: USB Connection issues

I have been having USB connection issues for 2 month and can't seem to find a fix. My MP is a 2 x 2.8 Quad-core with 16 GB ram, OS X 10.6.5. When I connect devices (iPhone, iPad, CF card reader) everything connects but when I sync or try downloading photos from my CF reader I get partially through but then I get an error that the device has been ejected.
I have tried disconnecting my hub and connected directly to the ports but no change. Tried new cords, hubs. If I connect my Canon 7D camera directly to a USB port I can get the images off but that take for ever because of the file size. The only thing that seem to work and not loose my connection is my Epson Pro 3800 printer.
I'm getting desperate at this point, I have two important photo shoots coming up the first of the year and need to get things working properly. Any help would be much appreciated.

Here's some tips.

HP PhotoSmart 7510 suddenly has severe connectivity issues

I have a HP PhotoSmart 7510 printer since about 2 months. Initial setup worked like a charm and the printer has been working pretty much perfectly for the last 2 months. Wireless printing, scanning and internet access on the printer (e.g. for Facebook photos) all worked. Just from time to time i would get the occasional (mildly annoying) message on my computer saying "scan to computer is currently unavailable" but it usually worked itself out and whenever I needed it to work, it did work.
But since a few days ago, it has some severe connectivity issues. I didn't change any settings on the printer, router or computer - the issues just started appearing by themselves. I startet getting much more frequent messages on my computer saying "scan to computer is currently unavailable". I noticed I couldn't print anymore, and restarting computer, printer and/or router didn't help at all. The only thing so far i managed to print wirelessly since the problems started were the first 5 pixel rows of an image I tried to print, the rest didn't transmit.
It seems the printer still connects to the WLAN but printing and scanning no longer work, and whenever I try to access a web service on the printer (like Facebook) it says it has no internet connection, even though the WLAN light is lit up (not blinking) and all the wireless status reports say "congratulations, no problems found" and display IPs etc. just like normal.
I looked at the threads "PhotoSmart 7510 connects to router, but not to the web.", "Wireless printer (HP Photosmart 7510) not connecting to network" and "Photosmart 7510 won't connect to Web Services" but they weren't a big help. Activating EWS didn't work because even though the printer showed its IP address to be 192.168.1.3, when I entered this in my web browser it didn't find the printers configuration page.
I tried the following steps from one of the threads:
1. Restore the Network defaults
2. Unplug the printers power cord while it is still on. Leave it unplugged and walk to the router.
3. While the router is still on, unplug the power cord from the router, leave it unplugged for 30 seconds, then reconnect the power cord to the router. Once plugged back in the router should power on automatically.
4. Plug the power cord back into the printer. Once plugged back in the printer should power on automatically.
5. Run the Wireless Setup Wizard to reconnect the printer to your wireless network.
6. Try enabling Web Services.
I followed these steps exactly. Interestingly, even though I had done step 1 and restored the network settings to factory defaults, after turning back on, the printer somehow still had its old settings saved and reconnected to the network.
It seemed to have fixed the problem, the printer finally had internet access again (Facebook app showed my photos) and scan to computer found my PC. But after just about 3 minutes, the printer had lost its internet connectivity again. When opening the Facebook app, it displayed the same error message it did before. And printing no longer worked as well.
So, what is wrong with this printer?! It has the newest software update by the way (I checked during the 3 minutes it had internet access.) My computer is a HP Windows 7 x64 machine (EliteBook 6930p) and the router I'm using is a Netgear WNDR3700.
I specifically bought this printer for my studies at university. In one week i have my exams and in order to study I REALLY need to be able to print some of my course materials! So any help as quickly as possible would be greatly appreciated. Or do you think this is a case for a warranty replacement, considering the printer's really strange and error-prone behavior?
Thanks a lot!

I can assure you that it is not a router issue. It appears to me that it is a driver compatibility with Windows OS. After trying to get to the bottom of this since my Photosmart 7525 was new and reading just about every forum and blog, I have come to the conclusion that the issue must be related to the HP driver itself.
The issue does not seem to affect any Mac systems, and from one forum someone was able to fix it by downloading new drivers compatible with 64-bit systems (which seem to not be affected by the glitch). But that leaves us 32-bit people stuck with the current driver which does not work.
The printer is connected with good signal to the wireless router (no matter who's router it is and what configuration is made). The printer can be pinged from the router and any computer on the network which is not currently being affected by this issue. However, the affected computer fails pings by either request timed out, or destination host unreachable. Pings are successful from the affected computer to any other device on the network. The only way to recover (at least for a few days) is to reboot the affected computer.
Also, from the display on the 7525, the network tests pass without issue. I can also download and print content from the internet with no issues.
Please do a quick google search of this issue and you will see several THOUSAND entries of people with the same request. This is a serious issue that people are having and everything is pointing to an HP problem (not routers, improper installation of software or drivers, etc...). I agree with several other customers that HP should be on the hook for this fix. I will give it another couple weeks, then back to the store for a reliable unit from another competitor (Canon, Lexmark, etc..)
Thank you in advance for escalating this issue to product engineering,
S. Hunn

Connection doctor and connection issues

I have nothing blocking my internet connection, however mail is a nightmare for me. I continually receive connection issues via the connection doctor for imaps, pops, and icloud.
Are my settings wrong? I have checked with each of the settings and they are set per instructions provided. Some are google, some yahoo, icloud, etc.
This is really annoying and I could really use some help.
Here is a typical message: Could not connect to this Google IMAP server. Check your network connection and that you entered the correct information in the Account preferences. Also verify that the server supports SSL. If it does not, deselect the 'Use SSL" checkbox in the Advanced tab of Account Preference"
I have done all of this and am still having troubles.
I am also receiving SMTP connection issues - "Trying to log into this SMTP account failed. Verufy that the username and password are correct."
I have checked and all are correct. Even more confusing, these issues are not present all the time - however I have not changed anything between when times are good and bad.
Sigh - I hope someone has an idea to help me out.
Thanks in advance for your time and thoughts.

Excel ODBC Connection Issues

I'm having some issues importing external data from an Oracle 9i database.
Here is what is happening:
I am initially able to import data from the table I want to into Excel.
I do this through "Data -> Import External Data -> New Database Query" where I have my .ORA data source. I'm able to log in using my user and password and import the table. My problems come after I import this first set of data.
If I try to "Edit Query…" I get an error box that says "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".
If I try to "Refresh Data" I get two error boxes. The first is just: "[Microsoft][ODBC driver for Oracle][Oracle]" and the next says: "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed". It then prompts me for the User name and password of the DB I'm connecting and after I enter the information, I get the same two error messages.
Also, if I attempt to establish another connection following the "Data -> Import External Data…" steps I run into a different problem. Upon entering the information for the User Name and password prompt I get two error messages. One says "!" and the next box says "Couldn't read this file". Once I click "OK" in those boxes, the Microsoft Query window automatically opens with nothing in it.
I can't seem to figure out why I can initially pull down data and then cannot succeed afterwards. I'm unable to connect to the DB I have through Excel until I completely closed all Microsoft Excel instances.
I also use this data source in Microsoft Access without any problems.
My Excel version is 2003.
I'm using Oracle Drivers I'm using are from an "Instant Client" package.
Any thoughts why I'm having these connections issues?
Thanks in advance.

This issue is closed.
The solution was:
"Data -> Import External Data -> Import Data"
Select "New Source" and select the "Oracle" data source and filled in the appropriate information. This was similar to the database query but it actually works.

My brand new mac pro always had Internet connection issues at school. WHY is that? I see the school's Internet working perfectly fine on other PC's, but there is never a day where my mac doesn't have Internet connection issues at school. How do I fix it?

I got my mac pro in the middle of August. School started the week after. Internet was working perfectly fine at home. But at school, I never had a good connection. Sometimes on the good days I get a connection when I'm sitting at the exact spot in class I always sit at. It's ridiculous and it's frustrating. I invested my money into this laptop and I'm beginning to regret it. I thought it was the school's Internet, but I don't see Internet issues with other PC users. It's most frustrating on registration days and I'm trying to register for my classes before it gets taken, but again... Internet connection issues. It's random. Majority of the time, it doesn't work at all. I've done Network Diagnosis and turning WiFi off then turning it on again. I've done everything I could. I put my money on this laptop and it was a lot of money. I could have bought an 800 dollars laptop and I would have Internet connection anywhere on campus. So, I don't want to continue everyday to regret on buying this laptop every time I try to connect to the Internet at school or Starbucks or anywhere else. How do I fix this? What's the problem ?
At school, I heard this guy had a problem with Internet connections too and he owned a new mac book pro. He said something like Apple messed up on something, but he fixed it. If I knew mac book pro's had these issues I wouldn't have bought it in the first place. It's freezing on me every other day. It's ridiculous. But what concerns me the most is the Internet connection. So someone please tell me what can I do next to prevent the problem? Am I doing something wrong maybe?

Hi Kevin,
I'm using an XLR input mic which is connected to the phantom power enabled XLR mic socket on a USB M-Audio M-Track. The M-Track is connected by USB to the Mac Pro - so effectively I've got an M-Audio USB soundcard with a mic input. I've also tried a microphone that is a straight XLR to USB cable (guessing with some soundcard chip buried in the usb plug) but that also yields the same effect of bad latency, intermittent quality, stuttering and repeating and echoing (without the speakers on during record so its not feedback).
The mic works absolutely fine with other recording applications I have on the mac at the moment - albeit non-adobe ones (tested it on the EasyAudioRecorder - and it lives up to its name. it's easy)
I will try with Audition and report back, but sitting here right now I can imagine it would work fine with audition too - it just seems to be the way premiere is set up for recording into the timeline is a bit sketchy. I'm willing to accept it might well be a quirk with the new Mac Pro trashcan - I'm not weighting all the woes on premiere.
Any thoughts or am I out of luck to sit with my fingers crossed for a fix in the next round of updates?
Nathan.

Connection issues with Safari 3

I'm having some connection issues with Safari 3.
When I connect wirelessly, Safari won't load any web pages. I go and use Firefox and everything is just peachy.
I've reset Safari, emptied the cache and whatnot. I went in and checked the permissions, everything checks out.
When I connect with Ethernet, there's nothing wrong, which is my dilemma.
Help would be greatly appreciated.

There are a number of posts in the Leopard forum from people with direct experience with upgrading from Panther to Leopard. Here is a relevant thread from there that should reassure you.:
http://discussions.apple.com/thread.jspa?threadID=1418714
Your system should be fine for Leopard, but you will probably need a current version of Photoshop if you don't already have it. See this download:
http://www.adobe.com/support/products/pdfs/leopardsupport.pdf
Also, Leopard doesn't run Classic (OS 9) apps.
One caveat - first make a bootable backup "clone" of your present system onto an external firewire drive so you can recover if anything goes wrong. You can use the "Restore" tab of Disk Utility to make such a clone, and there are also Panther-compatible versions of Carbon Copy Cloner (v 2.3) and SuperDuper (v 2.1.4), both excellent for this.
It's even possible to a create second Panther clone on a different external volume to create a "dual-boot" system, using that volume to continue to run old applications that you can't run with Leopard.

Connection issues with EA4500

I had bad connection issues with my mobile device, so i pressed reset on my EA4500 router, and now when i connect to my network, it gives my limited connection even though i have 5 bars of signal. Not sure what to do now...

Resetting the router will erase all the settings you configured on the router since the initial setup. You manually configure the router's wireless settings so your wireless devices can have internet access again.

Make sure to use a computer that is hardwired via Ethernet cable to the router.

X1 Carbon (20AX series) wifi connectivity issues

Dear Lenovo Support and all others,
I am posting this in hope that someone can help with my problem and also to share my unpleasant experience with a new Lenovo product.
Lenovo Thinkpad X1 Carbon
Model: 20A8A00VSG
OS: Windows 7 Pro 64bit
Purchase date: 27th February 2014
Since the first day I purchased the system, I have been having an issue with my wireless connection:
1. I am unable to reliably get a wireless connection to wireless access points (e.g. free wifi coffee outlets or malls) and personal mobile hotspots (mobile phone hotspots). It constantly says "LIMITED CONNECTIVITY". In other words, I cannot get internet access. Even when it does connect to the network and get internet access, there is a tendency for the connection to drop back to "LIMITED CONNECTIVITY".
The only time I can get a reliable connection is when I am connected to my home wireless router. The system does not seem to have problems on home wifi networks. Since the problem seems limited to wireless access points and hotspots, I believe its a hardware/software problem.
Please note that I have other wireless devices (laptops and mobile phones) that can connect to the same networks that I am trying to connect to and have no issues.
I have tested the networks with my friends' wireless devices as well and they have no issues accessing the internet so I am fairly certain that there is no issue with the networks themselves.
2. I have already called in twice and been given advice on both occasions but the problem still persist. I have updated all drivers, uninstalled and reinstalled and updated the BIOS for the system and also performed a system recovery but nothing has worked so far.
I have also tried disabling and/or deleting any anti-virus software and firewalls but it does not fix the problem.
I have also been advised that I need to go down to the Lenovo service center to have my laptop checked out by the technicians and that there MIGHT be a firmware upgrade for the wireless card itself.
NOTE: MIGHT? The support staff doesn't even know for sure whether there is an upgrade available.
3. Rebooting my computer, the wireless card or the hotspots does not solve the problem. It might work for a shortwhile before it reverts back to it's non working state or stops working again once I reboot the system.
I am really unhappy with the purchase so far. It's actually a good laptop per se when all is working, but without internet access, it is pretty much like a dead fish. And thats 90% of the time.
Like I said, this problem has been happening since day one and I've tolerated it long enough.
I hope someone can help me with this problem.
Thanks all.
UPDATE - 3/24/2014
I borrowed an ASUS Wireless USB adapter from a friend and installed it on the laptop. Lo and behold there are no connectivity issues to my iPhone wireless hotspot.
INTEL DUAL BAND WIRELESS AC 7260 - NO CONNECTION/LIMITED ACCESS
ASUS USB N10 WIRELESS ADAPTOR - CONNECTIVITY AND INTERNET ACCESS
I think this narrows it down to the software/hardware in the computer....

Hi, all
there is an issue bugged driver or even card firmware related. Intel confirmed that. Wait some time for the new release.
For the test purpose only disable 2,4 ghz band support and switch to 5 ghz. N-band seems unstable so switch to G-band. As the Linux users report the same issue it's firmware bug basically.
