D-Link DIR-615 :: It Freezes Every Night And Reverts To Factory Settings When Power-cycled
Dec 4, 2011
Our DIR-615 has started freezing and when reset (power cycled), it reverts to factory settings.This has been running 24/7 for several months with no problem. Three days in a row now I've woken up to find our home network is down and the DIR-615 status lights are "yellow". Power cycling the DIR615 resolves the problem however the DIR-615 looses its settings, reverting to factory defaults (looses the admin password, wireless settings, etc). I can reload the settings from a file saved on my computer but needless to say, this is a bit annoying. I don't believe there are any wireless clients connected at the time as most of the wireless is served by an airport two floors up. There are several wired devices always connected:
a Zoom ATA carrying our "land line"
a tivo (doing whatever tivo boxes do)
a SSL based Voip phone (different than the zoom ata)
an AirPort Express 802.11n (bridge mode) which may have a couple of wireless clients
a laptop which may or may not be sleeping at the time
There are a couple of ethernet switches in the network.Some of the devices acquire addresses via DHCP, others are assigned fixed addresses outside the range of the DHCP addresses served by the DIR-615.Nothing has changed on the network in months.
The only settings I've messed with on the DIR-615 are:
a) set the admin/user passwords
b) Set the wireless network name, enable WPA, set the WPA Key
c) enabled ntp (this is now disabled and I've set the time manually)
d) Change the network base from 192.168.0. to 192.168.4.
The DIR-615 is hardware rev E3, Firmware 5.10 The cable modem (from RCN) is a Scientific American model DPC2100R2
What would cause my Dir-825 to magically revert to it's default settings? This is the 4th time this has happened.We rely on a Verizon Network Extender for phone service. It requires an internet connection to function. When the router brain-farts, we don't have phone service... and we don't know it until we try to call out, or try to use the internet. We went to bed last night with the router working and woke up to it not working. It's just my wife and I here. I haven't seen the dog showing any interest in jacking with our computer gear.
When I access the setup utility and go to Manual Wireless Network Setup, the Wireless Network Name has defaulted to dlink, and Security Mode is None. I have to re-enter my personalized setup info, (because that is what our computers are looking for), then all works fine again.I'm a savy XP user, my wife has Vista (yuk) (she doesn't know any better; her daughter installed it).We are Comcast customers. We own a Linksys CM-100 modem. (When I connect direct by hardwire, (i.e. bypass the Dir-825 router), from the modem to any computer, or the Verizon Network Extender, they function just fine. Setup utility for Dir-825 says we have Hardware Version B-1; Firmware Version 2.02NA.
Set Firewall settings to Endpoint Independent for TCP and UDP. I see other posts addressing similar issues of reversion to default settings... but there don't seem to be any clear resolutions of these issues. On 2010-03-11, gunrunnerjohn posted, "I think there may be a shadow file that's actually in the FLASH that needs to get written back to make the changes stick. I seem to recall there is a command to sync the RAMDISK copies to the FLASH." Yet there is no more to this thread.
My computer is an XPS 360 with alot of upgrades. After looking at the specs of D-links routers I thought I give it a try. Hooked up, works like a dream. Couple months later my computer was saying I have "limited connectivity." All of the other computers have full access and works great. I tried going to my routers home page, but all I get is "The server at 192.168.0.1 is taking too long to respond." Ive tried renewing the ipconfig, restarting everything, new cables....everything I can imagine. I tried calling my ISP and they told me it wasnt there fault, that its pretty much on my end. I called Dell for support, said my warranty went out and they cant do a thing.
I currently have this router in use with verizon dsl (PPPoe) setup.I have this set to "always on". Since the verizon modem, which is also router has been set into bridge mode and the d-link came into play its been extremely slow, and dropping connection. The router is in a separate IP class, and has no conflict with the modem. My question is, if I upgrade this firmware from 1.0 to 1.02 will it default to factory settings? I know it says only some will. I do have the backup config file, but i would be doing this remotely, and would not be able to get to this router if it goes down. Has anyone gone from 1.0 to 1.2 and saw a difference and speed, and are you able to do this without losing settings.
Firmware asa805-k8 was installed and saved on an ASA5505. Upon power failure the ASA5505 reverts to an older firmware, asa724-k8. 1) Is it normal for ASA5505's to revert to older version upon power failure. 2) ASDM/web browser doesn't work using IE--username and password brings to empty screen. how to revert back to later image.

I have rebooted my netgear router to the factory settings and now the internet wont work , i have no idea how to get it to work again. On the box all the right lights are green exept the internet light which is red.
I am locked out of my Arris wtm652 (unable to login with default password or the password that i set). I have tried every way I know of to reset the modem outer to its factory settings but to no avail. I know that it is not being reset because I still can not login to it and it is maintaining the wireless security settings that were set for it.
Got a Belkin wireless modem router some 18 monthes ago, and after a bit of a struggle managed to set it up. It worked fine, aside from the odd depower repower. For some reason, it just stopped working yesterday. I initially checked all my cabling etc and everything seems fine. I next tried resetting my modem/router to factory settings. When I tried to install the Belkin software I fell at the first hurdle with a message saying "The setup assistant is not able to connect to the router". After googling my issue, I followed others advice and running the cmd setting and typing in "ipconfig" only to find that my media state was disconnected.
Had to so a install back to factory settings now I have no access to Internet, says network controller is missing, have tried downloading drivers but obviously not downloading the right one.
My DCS-942L is almost always in night mode with IR on resulting in a B/W picture. Only when the light is very bright it changes to day mode. How to adjust the day/night threshold?
I just restored my computer (Windows XP) to factory settings and it won't connect to the internet. I'm running an ethernet connection. I tried to look up a solution online but nothing has worked. Also, Im sure its not an issue with the modem, because all the other computers in the office are connecting to the internet just fine. It's only this one computer?
The ap 3502i has been registered to the wireless controller, but now want to restore the factory settings, repeated after the upgrade or will appear before the registration information of the wireless controller,
We need to "reset" a SG200-08P switch back to the factory default settings and noted the "Quick Start Guide" implies the "Reset" button next to the power button doesn't exist and refers the user to the "Cisco Small Business Smart Switch Administration Guide" for instructions. We couldn't find any information related to a "factory reset" in that document either. Pressed the "paper clip button" on the switch but we still can't get in.
Just set up 2 dcs-942 cams, and both were working fine. Now for some reason, the ir on one is not working, or very dim. This is in complete darkness, and its not seeing anything beyond 3ft. I've tried unplugging it, but didn't work. I haven't tried a hard reset yet, but may have to. Btw, no difference even if I force dark mode.
I use Cisco switch sg300-28. When i turn it off and turn on, it reset to factory reset include login password, dose it normal operation or I miss anything?
A few hours ago, I just restored my laptop to factory settings. Once it was done, I tried connecting to the internet but the computer could not detect ANY wireless networks!I already know it is not the modem or router because I have a Macbook Pro and two HP laptops that connect perfectly fine to the modem. I also made sure the wireless is on. The laptop with the problem is a Toshiba Satellite l645. It's running on a 64-bit Windows 7. When I try to look up wireless networks, it only shows 'MOBILE BROADBAND CONNECTION".

I have windows vista, and forgot my network password. I reset my router to factory settings by pushing the reset button on the back.I tried reconfiguring the router from the network icon, but at the end of the process it says it cannot configure my router.I lost my internet service in the process
I was having some connectivity issues with my network of WAP54G's, so I had a technician come to have them looked at. The technician turned out to be completely clueless, and he messed up one of the APs in the process. He changed its IP address and apparently updated its firmware, but he didn't write the new address down, so now I can't access its administrator panel. I've tried to retrieve the IP address using the setup CD that came with the AP, but it doesn't even see the AP in my network. I've tried to factory reset the AP by holding the reset button for 10, 30 and 60 seconds and unplugging the power cord, but to no avail. It still doesn't bring up the admin panel when I enter the default IP in the browser. I think I've tried everything I could find on the Internet about this problem that didn't involve cracking the AP open, but none of it has worked.
Iused my installation cd to re-setup my linksys. I moved and used a laptop previously. Now i am at a house that has a desktop. I want to keep the desktop wired and make my laptop wired. So, when i went to re-install it said i had to reset my linksys to factory settings.

Recently purchased a RVS4000 Router, which included v1.1.14 firmware. Is it necessary to reset the router to Factory Default settings, after upgrading to v1.2.11, as in most of the other previous upgrades?
I have a DCS-932L camera setup in my living room with motion detection activated in DView. During the day it works great, but after nightfall the camera shows random lines in the [poor] video. These lines are being picked up as motion and as such the camera records all night long taking up massive amounts of disk space. Even when I put the camera motion detection on 'lowest' value, it still picks it up.
I had something strange happen to my WRVS440N router yesterday. Our network had crashed for some reason. So I attempted to log into the device to see what was wrong and I was surprised to discover that all of the settings including user name and password had reverted back to factory default.
1. What are all of the possible scenarios that would cause this to happen?
2.Would disconnecting power in the middle of a boot up sequence cause the router to revert to factory settings?
I've just bought a pair of WAP121 for testing and validation. I've set it up properly (user/password, IP, management vlan, NTP, SNMP, 802.1x, etc). So far, so good, everything worked as expected. I've downloaded the configuration to my PC, and also saved it to startup-config. I've powered off the unit, went for a coffee, and powered it back. All my settings were lost.
Tried to restore settings from the file downloaded to my PC, but no luck. After reboot, it was factory clean, no trace from settings in the backup file. I've set it up again by hand, power cycled it, and the **** thing reloaded to default settings.
Faulty unit, I thought, so I opened the other one I have, and repeated the whole thing, but same results. Test were made using the power adapter supplied but also tried with a catalyst 2960 with PoE.
I have a DIR-600 (firmware 2.05) connected to internet and my computer. For a week or so, for some reason, there is a high number of SSDP messages on my internet cable (about 100/second). Probably a faulty equipment from the internet provider.
The problem is that this high traffic of SSDP messages cause the router to freeze, the instant I plug in the internet cable.
I have tried to block in the router firewall the address 239.255.255.250 on port 1900, but it get the error "invalid address". I have also disabled the Upnp function on the router, but without result.
How can I block these messages, so I can use my router again.
What do the broadcom power saving mode settings mean? If power saving mode is enabled, what is the time it takes to go into power saving mode? What does fast mean?
I upgraded my 3602i survey ap the other day to the public image the other day and I have to say.. I've got it up and going of course, but I have a concern on the transmit power settings. Originally, the only option it gave me was MAX and -4, which I hadn't seen before, interesting.. -4 of what? 20? 17 probably or I though? At any rate, I went into the CLI to set the power manually, no issues there, though my options are not what I expected, maxing out at 25mw basically, which is fine but.. in setting it manually in CLI, the web interface reports an Error on transmit power. So.. does this work or not? Any survey with this image to verify it's power settings? 15.2(23c)
