WRT1900AC - Enabling/Disabling UPnP Causes Router to Reboot

I've been doing some testing here and there with the WRT1900AC and I noticed that whenever I enable or disable UPnP, the router reboots within a minute. Can anyone else confirm this behavior?

Hi melvin7822. Thank you for bringing this to our attention. We would like to get the Team to check into this case. Shoot us an email at [email protected] with your contact details and the link to this post.
We look forward to assisting you.

Airport Extreme external hdd causes router to reboot

When I try to access my external WD hard drive (formatted to FAT32) on my AirPort Extreme, it freezes and causes the router to reboot. How do I fix this?
I am accessing the hdd from windows 7 pc.

Try adding a powered USB hub....even if the WD drive has its own power supply.
Reason...the USB port is borderline as far as its ability to supply sufficient power for a hard drive even when the Extreme is new and even when the drive has its own power supply.
If the Extreme is a few years old, it is not delivering as much power to the USB port as it once did, and it needs some help.
Worst case, the internal power supply on the Extreme is starting to head South. That is usually not an issue until the device is 4-5 years old.

WRT54G2, FW 1.5.01 - Website Blocking by URL Causing Router to Reboot?

Has anyone seen an issue with the use of this feature causing the router to reboot frequently? Seems to be more prevalent with the amount of traffic. Router recovers but drops all wireless clients and real time protocol (voice) sessions are interrupted. I only had 3 rather short request URIs blocked--wasn't asking too much of the thing. Soon as they were removed, router was steady as a rock...
Anyone else seen the same thing/found a solution?
Thanks in advance!

Hard-reset the router for 45 seconds and try to configure the router again...

Vista causing router to reboot

Having problems with connecting my new Vista laptop to the home network. Every time I turn on the Vista computer either from sleep of from being full off, wired to the router or wireless, after logging in to Vista, the router reboots and causes the modem to disconnect leaving all network computers without internet connection and it takes anywhere from 1-5 minutes for it to come back. I have been using static IP addresses with the router, tried it DHCP and still the same problem. I am using the WRT54G Ver 6 w/1.02.0 firmware. Tried connecting to my neighbors unsecured WRT54G Ver 4 router and it worked fine, no problems or rebooting. Dont know what could be causing this but I am ready to send back this new computer if I cant figure it out soon. Any help would be appriciated since I am pretty much out of options. Thanks.

I think I'll take back my WRT54G and get the WRT150N now

Links in emails are not opening.. Have tried rebooting, enabling/disabling restrictions in settings but all in vain! Any help or suggestions would be gladly welcomed.

Anyone know anything about getting links to open in emails? It's as though links are just not responding.. Have tried settings/general/restrictions and enabling / disabling but to no avail.

A few more things you could try:
Settings->General->Reset->Reset All Settings...you will then have to log back into your wifi network
If you have access to your router's settings you could try changing the channel your network is on.
Try changing the password/key of your router...a bit of a pain since all other devices will have to login again but sometimes it can help with connectiviity issues.

Do you have to disable UPNP to use port fordwarding

I have a E3000 and I am having a bunch of problems getting xbox live to work. I have a feeling I am going to have to go the port forwarding route. The question I have is do I have to disable upnp to use port forwarding or can I just leave it on?

Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
On the set-up tab change the MTU Size to 1365 and click Save Settings...
Click on "Administration" tab and disable the option UPnP and click Save Settings...
Click on "Applications and Gaming" tab and then click on "Port Range Forwarding" subtab...
1) On the first line in Application box type in ABC, in the start box type in 53 and End box type in 3074, leave the protocol as both and under ip address type in 192.168.1.20 and check the enable box, click Save Settings once done...
2) Once you return to the set up page click on the Security tab and uncheck Block Anonymous Internet Requests and click on Save Settings...
3)Click on the Status tab and take note of DNS1 and DNS2 Addresses...
4) Goto the XBox Network Settings and IP Address Settings and select manual IP Settings and assign the following on your Xbox, IP Address :- 192.168.1.20, Subnet Mask :- 255.255.255.0, Default Gateway :- 192.168.1.1...
5) Also assign the DNS Addresses on the Xbox, Use DNS1 and DNS2 Addresses you took note off of the router status tab as Primary DNS & Secondary DNS for the xbox...
6) Turn off your modem, router, and Xbox...Wait for a minute...
7) Plug the modem power first, wait for another minute and plug the router power cable, wait another minute and turn on the Xbox and test it...it will connect...

My iPad2 no longer connects to my home wifi network but there is no problem connecting to other saved wifi networks. Currently using iOS8.0.2. with storage capacity of 12.2Gb but only 147Mb free. Disconnecting the router and rebooting the iPad worked

My iPad2 no longer connects to my home wifi network but there is no problem connecting to other saved wifi networks. Currently using iOS8.0.2. with storage capacity of 12.2Gb but only 147Mb free. Disconnecting the router and rebooting the iPad worked briefly as a temporary fix but not anymore

You could try this
Temporarily disable security on your home network
See if the iPad connects
If it does then reset the security - with the same or different password

Since installing Firefox 29, my router constantly reboots on its own

Since installing Firefox 29, my router constantly reboots on its own. Is anyone else having this problem? And could it indeed be caused by Firefox?

Do you have any security software that may undo changes and restore a previous setup?

Shared Variable Engine Buffering Enable/Disable

Hello -
I am running into a problem where I am seeing a read of data that seems to be lagging the writing of the data. The reading and writing functions are utilizing the same shared variable - a control to write to it and an indictor to display it somewhere else. The indicator is lagging by one value, ie. scrolling up the value from 1,2,3,4.. will yeild in a display of 0,1,2,3, lagging by one. I am writing/reading to/from a value in a PLC using an OPC server, binding the variables to the control/indicator.
I am assuming it is the buffering which is causing this, but I can not seem to find where the buffering is enabled/disabled.
Has anyone seen this behaviour before? Also, where do you configure the Shared Variable Engine to disable buffering?
Thank you in advance for your help -
John
PS> One other note, Datasocket binding of the control/indicator does not yield any problems.

John,
Buffering is configured in the main window of the shared variable (double click on the shared variable in the project). Also, you will see this behavior if you have the RT FIFO enabled and you're using the variable on a Real Time target.
I would also recommend taking a look at this white paper which covers the workings of the shared variable:

Cannot disable UPnP..

Hi.. i'm having trouble disabling my UPnP feature on the 9100EM.. what happened is that I have several guests who will be sharing my internet, and I don't want them to use UPnP to open up my ports for something such as torrenting.... I don't trust anybody in my network except for me so I need make sure they're not doing stupid things with my internet..
After I disabled UPnP on my router, I deleted all the ports that are being forwarded, but what happened is that when I run an UPnP application, it forwards that application's port automatically. I'm currently running on 1.03.00.08 firmware.
This is how I disable my UPnP:
Advance - UPnP - uncheck "Allow Other Network Users to Control Wireless Broadband Router's Network Features"
But it did not work for me..
Any help will be very appreciated.. Thanks in advance

if you have FIOS tv services, do not disable UPNP as many of your tv services require UPNP
That's incorrect. FIOS-TV does not utilize UPnP.

Disable or quiet UAC without reboot from command line

I need to be able Disable or quiet UAC without reboot from command line without user confirmation as local system
We use LANDesk and I want to add a part of the script to install turning off or quieting UAC, run install and them turn UAC on
Not all users are Admins so I can run as current logged on user but if admin rights are not need I can run a pre install task as local user run the
install task then run a post install task to turn it on
It doesn’t have to be a command line it can be an app Ii position on each machine then call if it can run silently

Hi,
Thanks for posting in Microsoft TechNet forums.
To disable UAC, you can take either of the following methods:
1.
If you use Group Policy to manage UAC, you can edit the local security policy to control this:
1)
From the Start search bar, type "Local Security Policy"
2)
Accept the elevation prompt
3)
From the snap-in, select Security Settings -> Local Policy -> Security Options
4)
Scroll down to the bottom, where you'll find nine different group policy settings for granular configuration of UAC.
2.
Use the following script to elevate the privilege in Windows Vista.
Scripting Elevation on Vista
3.
You can also modify the registry through the following command line:
REG ADD HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0x0 /f
Important caution:
please backup your registry before modifying it, any incorrect modification can cause a unrecoverable damage.

Why can't we simply have an option to enable/disable Javascript on sites again in the settings for Firefox 27? Suddenly my Gmail attachments won't open. Gmail.

Suddenly my Gmail attachments have stopped opening, and I receive the message: JavaScript must be enabled in order for you to use Gmail in standard view. However, it seems JavaScript is either disabled or not supported by your browser. To use standard view, enable JavaScript by changing your browser options, then try again.
I found a Mozilla support thread where it was explained that Javascript has been turned off for a while in FF. OK. Then there was a complicated answer about how you could still turn it back on by typing in a config code into the address bar. What? Or, you could download an extension to do that for you. Why?
Please-- if you really feel like users can't be trusted, and Javascript must be turned off, at least bring back the ability to enable/disable Javascript on a per site basis in options, without having to know code. It's Gmail.
Thank you.

There is nothing on that thread that says Javascript is turned off by default. to quote:
"In Firefox 23, as part of an effort to simplify the Firefox options set and protect users from unintentially damaging their Firefox, the option to disable JavaScript was removed from the Firefox Options window.
However, the option to disable JavaScript was not removed from Firefox entirely. You can still access it from about:config or by installing an add-on. "
The UI checkbox to disable Javascript was removed, but the option still exists in about:config (which isn't code btw, it's just preferences), nor was Javascript turned off by default, in fact the opposite is true, it is enabled by default with the option to disable it made a little more difficult to find, as only advanced users need to disable Javascript.
Please try to clear the cache and cookies for gmail, let's see if those are causing problems. [[Delete cookies to remove the information websites have stored on your computer]], [[How to clear the Firefox cache]]

Router continually reboots

hello,
I am pretty sure this qusetion has been asked a thousand times before but why does my router continually reboot?
If I just browse the internet and not use any applications that require a lot of connections all is fine. However, soon after starting a bittorrent client or uploading a large email the router decides it is going to reboot itself.
It isnt only internet traffic that causes this either, if i stream to my PS3 the same problem occurs, however the problem does not exist when sending files between 2 PC's.
I know this should all work fine as I was on Virgin Media before BT and never had any problems using the same configuration.
I have got a HH 1.5 with software 6.2.6.H and it is the second homehub i have had with exactly the same symptoms so i dont fancy calling the helpline only to be fobbed off and have it replaced with another one.
As an alternative can somebody please reccoment a good compatable router that i can buy so that i can chuck the BT kit where it belongs in the bin.
To give an idea how annoying this is I asked my wife to keep an eye on it and count how often she notices the router reeboot while she is using it and it has been 18 times in 2 days.

Generic setup instructions below for Netgear, similar for any other ADSL router. Details also in HH manual.

As of Firefox 36, disabling OMTC causes random crashes

As of Firefox 36, disabling OMTC causes random crashes in Firefox. This is particularly concerning, as THIS very support site (support.mozilla.org) has "please try disabling OMTC" as a common suggestion for a number of screen rendering issues. I think that going forward, asking people to "try disabling OMTC" will only WORSEN the issue, as a catastrophic Firefox crash which could cause loss of data is much worse than a screen rendering glitch.
To be clear, I am referring to the following setting in about:config:
layers.offmainthreadcomposition.enabled = FALSE

hello, could you provide your latest few submitted crash reports? please enter '''about:crashes''' into the location bar, copy the latest few report ids from there starting with '''bp-''' & paste them here into a forum reply. thank you
