IP Configuration failure - EX6120 Range Extender
So I have setup my Range Extender, everything seems to be working fine, except I cannot connect on the 5Ghz band. I just get the error report IP Configuration Failure. I'm connecting on an Andro...
Hello.
I have exactly the same problem with connection via 5GHz-band.
Computer is running Windows 10-64b, WiFi is Intel 7260.
My Computer is configured to DHCP and pulls properly an IP address when connecting directly to the Router.
But when connecting the Computer to the Range Extender 5GHz-WiFi, it does not pull any IP and Windows tells me that ther eis no internet connection.
When connecting to the Range Extender 2.4GHz-WiFi, the computer pulls IP address and Internet works fine.
The status page of the Range Extender shows connection to both router´s WiFi´s 2.4 and 5GHz.
Could this be a configuration error?
Best regards
Andreas
Hello sfallon36 and Andreas_1
I have seen that this could be a channel issue I would try changing the channel on the main routers 5ghz to see if the extender will start working.

I checked with WiFi Analyser and they are both on the same channel (36) switching the Router to 40. WIll let you know how it goes.
I have Virgin Media as my Broadband supplier, with the Superhub 2. I've switched that to modem only, which connects to my Asus RT-AC66U. I went into the settings of the Asus and switched the 5Ghz channel to 40 from 36, then went back on wifi analyser on my phone.
The 5Ghz channel from the router had gone to channel 40, but so had the extender..... However, they were both away from other 5Ghz systems in my area and gave it another try. For some reason it still can't get an ip address, same message.
Am I right in assuming the extender 5Ghz channel should be on the same as the original Router? Or does that not matter?
Hello sfallon36
Yes the extender picks up the channel that the router is using so they are both on the same channel.

- Hello. I had some time and investigated the issue more in detail. Conclusion and 'Questions are copied from bottom to the beginning, for the details read the post all the way down. ========================================================================== Conclusion: It appears that the EX6120 with Firmware V1.0.0.16_1.0.11 cannot extend two WiFis (2.4 AND 5GHz) at the same time. It can extend one WiFi (2.4 OR 5GHz) and add a second subsidiary WiFi to the extended ones on the other frequency band. This looks to me like a firmware bug . Questions to Netgear: 1. Does Netgear confirm the above conclusion? 2. What is Netgears response to this issue? 3. By when does Netgear consider to fix this issue? ========================================================================== Issue: No Internet connection on extended 5GHz WiFi and on LAN-port of EX6120. Pre-Requisites: - Main Router is working with two different SSIDs on 2.4GHz (SSID:Test_2.4, Ch:11) and 5GHz (Test_5, Ch:36) using same passphrase. - Target #1: EX6120 to be connected via 2.4 and 5GHz WiFi to main router and to create its own 2.4 and 5GHz WiFis with same passphrases as main router. - Target #2: Use of 2pcs of EX6120-100PES to extend exsiting WiFi from one floor to three floors. - Firmware is up to date V1.0.0.16_1.0.11 - Tests are performed with only one EX6120, the other ones is still in the box (for goods return purposes if needed). - Setup of EX6120 is set to "Repeater", main Routers WiFi´s are properly detected, passphrases are entered. - EX6120 SSIDs are Test_2.4_EXT and Test_5_EXT. - EX6120 shows to have good connection to both Main router Wifi´s (green indicators). - EX6120 Ethernet Port is configured to use 5GHz WiFi. - EX6120 Regional setting is Europe - All other settings are unchanged and factory setting . - Laptop is Sony Vaio SVP1310, Windows 10 with Intel WiFi card a+b+g+n+ac+Bluetooth - Laptop connected to main router WiFi SSID Test_2.4: internet is available, connection okay. - Laptop connected to main router WiFi SSID Test_5: internet is available, connection okay. - Laptop connected to EX6120 SSID Test_2.4_EXT: internet is available, connection okay. - Laptop connected to EX6120 SSID Test_5_EXT: Does not receive IP-address (DHCP not working?), no internet connection. - Wireshark traces on computer connected to Main router show that absolutely no traffic passes through EX6120 , coming from Laptop. - Laptop#2 connected to Ethernet port of EX6120, configured for DHCP, does not recieve IP address, no internet connection. - Wireshark traces show a short period of traffic passthrough via EX6120 (via Ethernet port or 5GHz WiFi) when applying changed settings to EX6120. Passthrough Time frame is 8 to 16 seconds. 1. Check if WiFi Channel change on main router would improve situation Performed action: change channel from 36 to 40 Result: No change on Laptop and Laptop#2 Performed action 2: change from channel 40 to 48 Result: no change on Laptop and Laptop#2 2. Factory setting of EX6120 and exact identical configuration as before Result: no change on Laptop and Laptop#2 3. Re-Flash Firmware into EX6120 V1.0.0.16_1.0.11. Result: no change on Laptop and Laptop#2 4. Change Ethernet Port to use 2.4 instead of 5GHz WiFi 5. Result: Laptop#2 =internet is available, connection okay. Laptop=no change 6. Change passphrase of Test_5 and set EX6120 again to use same passphrase as Test_5 for Test_5_EXT. Result: Laptop#2 traffic passed for 16 seconds. 7. Set back identical passphrases for Test_2.4 and Test_5 on main router and set one new different passphrase for Test_2.4_EXT and Test_5_EXT on EX6120. Test_2.4_EXT and Test_5_EXT have now different passphrase as Test_2.4 and Test_5_EXT. Result: Laptop#2 traffic passed for 3 seconds. 8. Set two different passphrases in EX6120 for Test_2.4_EXT and Test_5_EXT Result: Laptop#2 traffic passed for 2 seconds. 9. Extend only 5GHz WiFi (Test_5, Ch:36), using same passphrase for Test_5 and Test_5_EXT and Test_2.4_EXT . Result: Laptop#2 internet is available, connection okay. Laptop internet is available, connection okay. Conclusion: It appears that the EX6120 with Firmware V1.0.0.16_1.0.11 cannot extend two WiFis (2.4 AND 5GHz) at the same time. It can extend one WiFi (2.4 OR 5GHz) and add a second subsidiary WiFi to the extended ones on the other frequency band. This looks to me like a firmware bug Questions: 1. Does Netgear confirm the above conclusion? 2. What is Netgears response to this issue? 3. By when does Netgear consider to fix this issue? Looking forward to a positive feedback Regards Andreas
