If you can login Qnap without problem when directly connect to a laptop, but you cannot login Qnap when you plug to your Network, these titles may cause this problem;

I - Ip Conflict

II – Firmware Error;

III – Wrong Load Balance Configuration,

 

II – Qnapfinder can find my Qnap but when I double click on NAS, it says “Page Couldnt Found”

First, we must be sure if you configure and check basic setting;

1 – Plug Qnap directly to your Laptop / Pc

2 – Be Sure if Qnap and your Laptop / Pc is on the same Subnet

3 – Use different Web Browser. / clean Cookies of you Browser.

Open Google Chrome, then type this;

http://169.254.100.100:8080

 4 – Be sure that you close Antivirus or Firewall

Both of them is working at my computer, and I can login any costumers Qnap NAS device without Problem. But examle Karspersky + Qnao NVR devices cause problem to login and I have to close Karspersky program to use NVR)

 

III – I can Login Qnap when I directly Plug in to my Laptop, but when I plug Qnap to our Network, I cannot Login Qnap anymore.

Be Sure if there is no  Ip Conflict with Qnap IP. To understant this, please follow;

1 – Take out Qnap from your network and ping Qnap ip adress if its exist;

For IP possable conflict, Plug out Qnap’s ethernt cable from your swith, open command (windows -> start, then typ “cmd”) and type “ping 169.254.100.100″ (or whatever is your Qnap ip).

If this command gives reply, Plug Qnap another computer and change Ip adress which doesnt exist in your network.

2 – Change Qnap IP

Some device in network may not be reply your ping, so change Qnap Ip adress for this possability.

Before give Qnap another Ip, again go windows -> start ->cmd and type

ping 192.168.2.210

ping 192.168.2.210

If you take “no respond” message from this IP just like in this screenshot,  give this IP to Qnap

If you take reply like in this screenshot, DONT GİVE THİS IP TO QNAP.

.

IV – Qnapfinder can find Qnap, but Qnap firmware seems different?

If your Qnap Ip seems different like “1.0208″, this maybe a HDD or Firmware Problem;

Generally a new mainboard spare part comes with this firmware. To identify what cause this problem, simply shut down Qnap, Plug out HDD’s, and open Qnap back again.

a – If after Qnap restart, your Qnap Ip seems like  ”3.2.1″ or “3.7.1″, it means there is problem with your HDDs

Try to press reset button more than 15 seconds and check if problem still exist. If it doesnt work, contact with Qnapsupport Taiwan.

b – If after restarting device without HDD, your firmware still seems like this, start installation from first time. when Qnap request to show firmware, use 3.5.1 or down below firmware version. Installing fimrware may take more than 30 minutes, so wait patiently and dont close Qnap at this process.

If problem still continue, Please check my “Firmware Reflash Document” to solve this issue.

 

V – Qnap becomes unreachable after Load balance Configuration;

To Use Qnap Load Balance Feature, your swithc must support Load Balance and you must enable / configure Load Balance on your Switch,

If you didnt do this, simply plug out second lan port to make Qnap reachable again.
