ryn0909 0 Posted March 21, 2015 i have an isis anf1648 standalone dvr runnin montevista linux and have lost the ability to connect to internet via the rj45 ethernet port. ok so now i have a bigger problem, for some reason, the network settings are screwed up and when i change them to what they should be, i save it but the setting go right back to where they were..... heres what im talking about> Login as ADMIN---> setup---->system setup--->network---> IP SETUP. CURRENT SETTINGS DHCP: (checkbox) checked Web Service: (checkbox) checked Ip Address: 255.255.255.255 Gateway: 0.0.0.0 Subnet Mask: 255.255.255.255 1st DNS Server: 192.168.1.1 2nd DNS Server: 0.0.0.0 CORRECT SETTINGS DHCP: (checkbox) checked Web Service: (checkbox) checked Ip Address: 192.168.1.149 Gateway: 192.168.1.1 Subnet Mask: 255.255.255.0 1st DNS Server: 0.0.0.0 2nd DNS Server: 0.0.0.0 In order to change the ip addresses, i have to "UNCHECK" the DHCP checkbox. When i do that, it allows me to change the addresses how i want to but when i click on save at bottom of page, it will save it but as soon as i exit the menu and re-enter the menu, the settings have changed back to what they were previously. I have done the factory reset using the "hotkey" and its still doing the same thing. so as it sits now, i have no NETWORK access to the unit whatsoever. the serial debug console still works tho Share this post Link to post Share on other sites
jazzar 0 Posted March 21, 2015 once you change and save the settings try rebooting the unit - it may need a reboot to take on board the changes. Share this post Link to post Share on other sites
ryn0909 0 Posted March 21, 2015 well once i click on save it will reboot the network server and then if exit the menu and then go bavk into it, without rebooting the unit, the settings have changed back Share this post Link to post Share on other sites
Securame 0 Posted March 22, 2015 CORRECT SETTINGS DHCP: (checkbox) checked Correct settings should be with DHCP disabled (that is, unchecked). And use 192.168.1.1 and 8.8.8.8 as DNS servers. Share this post Link to post Share on other sites
ryn0909 0 Posted March 22, 2015 no, my settings arent the issue, its gotta be either firmware or hardware issue. i just wish i knew where to obtain firmware for it. Share this post Link to post Share on other sites
Samir 0 Posted March 28, 2015 Very strange. Are you able to check the router logs to see if the unit is actually attempting to get an IP address? Share this post Link to post Share on other sites
ryn0909 0 Posted March 29, 2015 its not even trying to do that. with or without the ethernet cable plugged in, it does the same thing. when i chk the debug console output, connected via serial (rs232) port, it says "can not read subnet mask" Share this post Link to post Share on other sites

Is there a way to factory reset the unit and reconfigure? Share this post Link to post Share on other sites
Samir 0 Posted March 30, 2015 already tried itAnyway to try connecting it to a different router to test? Share this post Link to post Share on other sites
ryn0909 0 Posted March 30, 2015 yea i tried that too. itm pretty sure its firmware. the nand flash memory says it has a bad block. id flash the firmware to it but i dont have a copy of the firmware and tried looking EVERYWHERE online. lol Share this post Link to post Share on other sites

ryn0909 0 Posted April 1, 2015 the funny thing is, i DID end up buying the exact same one. so i thought it was exact. apparently it was the model before this one. same manufacturer but with older software and firmware. but it DOES work tho, thank god. the main difference is when i connect to it via serial port, im not getting any output like i do with my newer (broken) unit. and the hotkeys arent the same. im not even sure if it has them implemented into it.

I had to replace a unit and the built-in http viewer worked differently than the old one, not working properly with the desktops we had. I actually had to find one of the older units--luckily, the distributor had one and gave me a killer deal on it. Share this post Link to post Share on other sites
ryn0909 0 Posted April 4, 2015 the thing that sucks the most is that its made in korea, and trying to get tech support from koreans is almost impossible for an american and i dont have any korean friends. Share this post Link to post Share on other sites

Numb-nuts 1 Posted April 5, 2015 CORRECT SETTINGS DHCP: (checkbox) checked Correct settings should be with DHCP disabled (that is, unchecked). And use 192.168.1.1 and 8.8.8.8 as DNS servers. That is unless you can reserve the DVRs IP in the DHCP (reservation table) which will reduce the chances of IP conflicts, then it won't matter if it's selected or not but frankly it IS better to leave DHCP unchecked (or on some DVRs select static) as advised (Not all routers will allow you to reserve an IP address to a specific device) Share this post Link to post Share on other sites
ryn0909 0 Posted May 1, 2015 well i managed to fix the problem with the rj45 port. the problem was in the firmware. after a gazillion factory resets and system reboots, it finally corrected itself. I was also able to get their tech support guy to send me the link to download the firmware file. but now the dvr doesnt see the firmware file on my usb flash drive. it sees the flashdrive itself and shows it as removable storage in the system menu, but the firmware file doesnt show up in the list. im using a san disk cruzer micro 4gb formatted fat32. i just dont get it..... any ideas??

tomcctv 190 Posted May 1, 2015 Hi. Make a new file on USB and call it dvr ... Then move your firmware to that file Share this post Link to post Share on other sites
