Can't use my router as access point.

Model: Archer C6   Archer C20  
Hardware Version: V4
Firmware Version: 1.13.1 Build 230609 Rel.31746n(5553)

Hi,

 

I have two routers, Arcehr C6 and Archer C20. I am getting my internet from the ISP on C6 and want ot use C20 as an access point.

 

The current IP from ISP:

 

Internet :

IP Address: 192.168.100.4

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.100.1

Primary DNS: 192.168.100.1

 

Current LAN on C6:

IP Address: 192.168.0.1

Subnet: 255.255.255.0 

 

I have set the IP as static on C20 at 192.168.0.2 and would prefer it to be this only unless it is not at all possible. I have disabled DHCP on C20. I also want the network name to be the same for both routers ( I don;t know if this matters at this moment). I only see the wifi names and am not able to connect to teh network once C20 is powered on. However, if I turn it off, it is working fine. 

 

How do I fix this ? I've been stuck for 3 hours.

 

Thanks,

Fenris

Hey

 

From what you have described, this appears to be a IP addressing issue, namely the 192.168.100.x network cant talk to the 192.168.0.x network.   You have two options

 

1.  Change the C6 address to 192.168.100.SOMETHING and that means its on the same network as your other router, this should then work

 

2.  Bit more fiddling required.   Change your DHCP to offer a subnet mask of 255.255.0.0 (not 255.255.255.0) that way it can connect to any network using starting 192.168.x.x     however I would then recommend setting your default gateway to 192.168.100.1 as primary and 192.168.0.1 as secondary

 

Personally, I would go option 1 as its WAY less stressful.   Your hardware isnt really designed for routing between different subnets, home grade stuff generally expects just one subnet in play and manually over-riding that is very messy at times!

  @Philbert I am sorry for the confusion. C6 is my main router and is getting internet form the ISP. 192.168.100.4 is the IP I'm getting from my ISP. The LAN on C6 is at 192.168.0.1 and the LAN on C20 is at 192.168.0.2.

Personally the second option made more sense to me. I'll try that and let you know. As for the first one, would your solution work with the address I mentioned above?

 

PS : Sorry if I'm being dumb.

Hey

 

 

Yes both should work for you fine, if you have an ISP router then all should be good.  The IPs you provided should suffice for that.

 

Is there a reason you want the APs on a different subnet?   Its really no advantage to you and will only add more complexity if honest.

  @Philbert I'm not sure if I'm putting them in another subnet. My first router and all my devices have IPs in the 192.168.0.OneHundredSomething. That was the DHCP pool assigned earlier. I have since changed it to 192.168.0.2 - 192.169.0.254

 

How am I putting them in different subnets ? I'm setting the IPs to 192.168.0.1 and 192.168.0.2 for the exact same reason. The 192.168.100.4 is the WAN IP and not the LAN IP. Not sure how that works. 

 

I appreciate you for taking out the time to help me out.

AH so the 192.168.100.x  address is the WAN.. ok get it now ignore me!    Looks like your ISP is running NAT also in that case, not uncommon in fairness but its usually a 10.x.x.x address and not a 192.x.x.x address.    I live in Ireland and our ISPs dont NAT so took a second to register with me.. :)

 

You should be good with your setup in that case :)    Follow the addresses you mentioned, should work for you

  @Philbert it's not. I'm stuck for 3 hours trying to figure it out. I don't understand what I'm doing wrong.

Ok 

 

Are you on a windows PC?  If so open command prompt and post a pic of the result to command   ipconfig /all

 

If you can even post a quick diagram of your setup that would help too

  @Philbert I'm on Linux mainly. 

 

The current setup is like this :

 

ISP >> C6 >> C20

 

I'm getting 192.168.100.4, 255.255.255.0 as WAN on C6. I've a wired connection between the LAN ports of C6 and C20 ( Let me know if I need to switch the port to WAN on C20, I tried it didn't work either). 

 

The LAN IP for C6 is set to 192.168.0.1 255.255.255.0

The LAN IP for C20 is set to 192.168.0.2 255.255.255.0

 

Not sure about the subnet mask on C20 as I don't remember it and can't verify unless I plug in a wired connection to it through my laptop with a static IP defined.

 

I have DHCP disabled on C20 and hence can't connect to it wirelessly. 

Let me know if you need any more info.

Hi, what is the hardware version of your Archer C20? And did you change operation mode to Access Point mode or only changing the IP address and disable DHCP server manually on the C20?

 

Please refer to the Case 1 in this guide to configure the Access Point mode again on the C20:

  @Sunshine Hardware version for C20 is V5. I have done both, i.e., changed the operation to access point and have turned off DHCP and assigned a static IP to it. Was I supposed to do only one of them ? If yes, why ? Also, I have connected a wired connection from C6 LAN port to C20 LAN port. Let me know if that needs to be changed.
