Dear forum,
I installed my eBlocker 1 week ago and was awesomely surprised how easy the installation was. Good work! Everything was even fine so far until yesterday. Since yesterday all my mobile devices (iPad + Android devices) in my network stopped reaching the internet. They were completely blocked. Neither internet pages in the browser nor mobile apps (such as Slack) were online. When I deactivate eblocker for those devices everything is back to normal, but unfortunately without eblocker protection. I tried all of what is described in this article: https://eblocker.org/docs/no-internet-but-the-eblocker-can-still-be-accessed/
No success. Do you have an idea?
P.S.: First I thought that eBlocker struggles with same naming of my devices for different IPs (when I move myself from floor to floor the Wifi connection switches from one repeater to another, everyone connected via LAN and not WLAN). This was due to the fact that I saw that my devices occurred multiple times in the devices list in the eBlocker admin area. Thus, I changed their names by adding a number to it. As a result I had devices in my list which are all uniquely named. But this made no good. Didn't work neither.
Please provide all infos from here to get focussed help: https://eblocker.org/community/announcements/before-posting-here-please-read/
As you say you‘ve changed some network topology (which probably caused the issue) please also describe your network setup in terms of routers/switches/repeaters/WLAN access points etc. and the changes you applied. (ie. Where are the clients connected not getting WLAN Internet access - I guess that‘s what you mean by „mobile devices not getting access“.)
Regarding your „double naming“ this sounds like a (new/changed) repeater is not in bridge mode (s. https://eblocker.org/en/compatibility/)
BTW: You can safely delete ALL devices from the device list, scan your network anew and start all over.
THX!
@random thx for your response
First things first - here you have the requested information:
- Hardware you use for running eBlockerOS: Raspberry 4 2GB+
- eBlockerOS version as well as filter lists version: 2.6.2, 2021-05-05-06-15-02
- eBlocker network mode (auto, individual or expert): auto
- eBlocker network settings (IP, mask, gateway): 192.168.178.136, 255.255.255.0, 192.168.178.1
- eBlocker DNS firewall settings: Custom list of external DNS servers (was the default)
- Client network settings (IP, mask, DNS, gateway): 192.168.178.127, 255.255.255.0, 192.168.178.1
- Whether eBlocker’s https integration is enabled for client: no
- Client browser and OS version (i.e. FireFox 80.1 running on macOS 13.4): Chrome 87.0.4280.163, iOS 14.4.2
- Exact way or a link / screenshot to reproduce the issue: no
- If VPN or Tor is enabled for the client in eBlocker (and which VPN provider you are using): no
- Router: AVM Fritz!Box 7490
- relevant topology:
- WLAN repeater connected via WLAN ➡️ client (iPad) is connected to this repeater
Changes I made:
- I recognized in the eBlocker configuration that there where many devices listed which are denoted as not connected
- those devices had generic names (e.g. "Device No. 1")
- based on the listed IP addresses I found out in the device list of my router that they belong to my respective client (iPad)
- thus, my assumption was that the different IP addresses stem from the fact that when I move the iPad inside my house it gets connection from other repeaters being set up on the other floors
- for being able to identify those devices directly in the eBlocker configuration I adjusted their names and changed them from "Device No. 1" to "iPad 2" (and so on)
- this is what I changed, I haven't changed the topology of the network from my point of view, I just changed their names
This evening I also noticed that I received a message in the client dashboard regarding the fact that a Fritz!Box 7490 has been detected and that this router is not compatible. It recommends to use eBlocker's individual setup. Is this what I should try? If yes, what is it about and good for?
Thanks in advance 🙏

There is aan issue FB7490 with eBlocker , best is to use "Network Individual Mode"
Hope this fix your problem, let us know...

@janhasfun Thanks for the good tech feedback! Very helpful.
I agree with @Pio78. For 7490 you must switch to Individual Mode (or Expert Mode). This will eliminate the WLAN issues. It‘s a known 7490 bug.
BUT: I suspect your repeater is not set in bridge mode or not compatible with eBlocker. This is causing the doubled devices, as the repeater is not properly propagating the MAC address of the client (which identifies the device - not the IP!).
Which repeater model are you using? Please also check if it can be configured to Bridge Mode or Transparent Mode (not changing client’s MAC addresses).
To prove the repeater is causing the doubled entries (after network setting to Individual Mode!): remove all devices from device list, unplug repeater, rescan network (other tab in device list). Then leave it for a day (or a few hours) and I bet not doublets show up. Then once you add the repeater and move devices in repeater range - the doubles show up again. THEN the repeater not kompatible or needs Bridge Mode setup...
THX!
Dear @Random and @Pio78, thank you a lot for your guidance. I successfully activated the individual network mode for my eblocker. Everything seems to work again. One learning for me was that the double appearance of the devices has nothing to do with the network mode but only with the capability of the repeaters of working in bridge mode. Unfortunately this is not the case for my repeaters (Netgear EX6120 + Netgear EX2700). I consider this a minor problem, do you agree? The drawback, from my perspective, is only that the devices appear multiple times, once they switched the router while moving. Can you confirm? Other than that, the activation of the eblocker as DHCP server seems to work. My iPad and my mobile phone are back in the game.
