Posted: Sun Jul 07, 2019 3:42 Post subject: wifi repeater
Yes I did. A few days ago...a more through reading is probably necessary, haven't had time yet. I've been trying this and that in between renovation tasks at home and then there is always work.
I'm like the jack of all trades when it comes to computers (programming being the exception-hate it). Meaning I know enough for normal everyday simple configs and a few intermediate things (pfsense, snort, apache etc,etc). I don't know anything about bridging and/or wifi repeating, never had to set it up.
I do know the wiki said it's best not to use WDS unless you have identical routers or at least chip-sets. Which I do not.
The difference between the versions is, I think, throwing me off. What is "client"? What is "client-bridge". Where is the "repeater" option on the Archer C7 firmware? I'm sure it's there, but which is it?
I'l go over the wiki again and see if I missed something.
Posted: Sun Jul 07, 2019 4:45 Post subject: OK re-read wiki and have a few more questions.
Repeater Bridge allows wireless AND wired clients - this is what I want but don't see the option in the Archer C7 firmware.
Primary router is configured in a 192.168.1.X subnet and leases DHCP address in the same pool. Secondary router is running DD-WRT.
Question: I assume any subnet will do as long as they're identical - I use 192.168.175.x
Question: - Will, and I assume so, all clients on the secondary router get their dhcp lease from the pfsense firewall as normal?
No security setup will be covered in this Wiki. It will be up to the user to set up security between the Primary and Secondary routers, must be identical.
ok, on the R6300 it's simple for me(very typical) "WPA2-PSK AES"
I assume the AES in "WPA2-PSK AES" is SHA256
On the Archer C7 version it's different terminology that, to me anyways, isn't clear. There are 2 choices for WPA2. WPA2 Personal and WPA2 Personal with SHA256.
Question: I assume WPA2 with SHA256 is all I need to check here?
Also, on the Archer C7 Wireless Mode I see choices of:
AP/Client/Client Bridge (Routed) /WDS Station/WDS AP/ and Mesh / 802.11s
I am looking for repeater but maybe I have to settle for one of the bridges and if so which one? I wanted the repeater mode so I could extend the network coverage also, however, it is quite possible to wire in the devices connected to the secondary router, the Archer C7.
Question: Should I choose Client or Client Bridge (Routed?
I assume Client Bridge (Routed) as I want all devices to be able to communicate with each other?
OR, would an easier, better solution be to just purchase another R6300 router ( I saw a few on kijiji in my area:-)run the same firmware on it as I am on the other one and bobs yer uncle?
As you can see, not having much experience with all this I am a little lost.

After all of the above I was going to log back onto the Acher C7 and do Status>Wireless>Site Survey>Join to the SSID of main router to connect to the R6300 to estabilish the client bridge. However, I cannot get the Acher C7 Web GUI to load - it says page cannot be displayed - even though I am connected to it via wire on my laptop. I CAN however browse the web with no issues whatsoever but I cannot connect to the WiFi-5g-VAP I created - it just says cannot connect - no specific error messages AND WORSE thing of all - inssider 4 reports the WiFi-5g-VAP is an open wireless network - but I can't connect to it either way and when I try it does not prompt me for a password - I am 110% sure I put the same passphrase on the VAP as I did on the ATH1 (5g) wireless radio. Dunno what this is all about.
However, I think I might reset and do this all over again - omitting the addition of a VAP (like I said I don't mind connecting 3 devices directly to the Archer C7 by RJ45 - its the wireless link between the two routers that is important to me.
I would be happy without the VAP honestly, but I want to be able to logon to the Web GUI of the Archer C7 -I was just trying it to see if I could get it to work. If I can get the wireless link working (and I know I did simply by the fact I am connected to the Archer, even now, and browsing and the Archer is not connected to anything via RJ45 except my laptop so there MUST be a wireless link established between the R67300 and the Archer.
Posted: Sun Jul 07, 2019 15:39 Post subject: More of a failure than I thought however...
@Per Yngve Berg -thanks for the response. I figured the main wireless should be the R6300. Am I wrong in thinking the hardware is better and will provide better wifi coverage/stability? If so, please explain?
I figured out the reason I couldn't load the web GUI. It had the same IP as the main router .I was tired. Either way, I got logged in again last night and simply changed the Archer router IP to what it should be (192.168.175.224 instead of 192.168.175.225)after applying that change I lost all connectivity on the Archer? No clue why that would happened?
After more than a few reboots I decided to do 30-30-30 reset and start over again. After the 30-30-30 reset the router now has nothing - no LAN connectivity (says cable unplugged on my laptop) and no wireless signal at all (it briefly flashes on boot and about every 30-45 seconds after boot).
Not sure but I may have pooched this router. I will try the 30/30/30 reset once or twice more and if that doesn't work I'll toss it out - had it for two years now and paid $60 for it so meh, whatever.
Posted: Mon Jul 08, 2019 19:19 Post subject: ALL GOOD NOW - WORKING AS EXPECTED AS CLIENT BRIDGE
Not sure what happened. I let the router sit overnight unplugged from electricity. This morning I thought what the hell, try one more time. I did not do 30-30-30 reset though, I just hit reset button for 10 seconds and after it was done I had access to wireless and LAN connectivity again.
I think I was "borrowing" to heavily on other peoples posts. Once I figured that out, I threw all the posts out and did what I thought would work on MY network (as opposed to some posters network). And it did work. The client bridge router is now sitting in my sons room with a wireless bridge to the primary wifi router. My sons devices are all wired into the bridged router via RJ45.
His connection speed went from average 20-25mbps to 130mpbs. He is happy, I am happy and more importantly, my wife is happy because the 50 RJ45 cable I had running from the basement office to the third floor is now gone:-).
SO, basically I used ALL of the steps on the bridged router from djkad's thread on how he/she did it with one exception. I did disable the dhcp server but I enabled the dhcp repeater - the only difference.
For the LAN setup of the bridged router I used the settings to get to my pfsense firewall like all the other devices in the house, but the bridged gateway IP I set to the IP of the primary wireless router.
I did not change anything on the primary wireless router at all.
If anyone is interested I can post my exact settings from pfsense firewall to primary wifeless router and then the settings for the bridged wireless router. I'll monitor this thread for the next week or so to see if anyone is interested.
Other than that - THANK YOU all for you comments and especially thank you to djkad for posting his tutorial on client-bridging, that was a game changer for me as it really opened my eyes to what settings would/should work.
Posted: Tue Jul 09, 2019 0:12 Post subject: dhcp repeater not needed?
Thanks for the advice.
I did try it with all dhcp disabled. It only seemed to actually work when I enabled dhcp forwarder (yes you're right no "repeater" in dhcp menu). My setup was fairly unstable at the time I had completely disabled dhcp though so who knows. Learning as I go here.
It most likely won't be an issue for me disable the dhcp forwarding and see if all is well though:-)
I'm just scared to turn the dam thing off or reboot it now though - it's finally working...sigh...
