Unable to connect to the Router setup after changing IP & factory reset (WNDR3700v2)
Hi Everybody, I got a new internet provider today, so i had to change the settings of my Router. Therefore i changed the Router IP to 192.168.0.2 (following a tutorial online), but after that...
- OK, well the rough process is as follows; 1. Log into the base router and find its DHCP server settings, set the DHCP range to end at some convenient address e.g. a range of 192.168.100.2 to 192.168.100.199 2. Connect to and log into the WNDR3700 3. Set all WiFi and other settings as desired, but don’t bother with any router related functions e.g. Port Forwarding 4. When you are happy with the settings go to the LAN Settings page 5. Set the router IP address to a convenient address on the same subnet as the base router e.g. 192.168.100.200, do not apply the setting yet. 6. On the same page disable the DHCP server and apply the setting, the configuring computer will now lose its connection to the ‘3700 7. Connect a LAN port of the ‘3700 to a LAN port of the base router, power cycle the ‘3700 8. Computers that now connect to the ‘3700 by wire or WiFi will now be allocated IP addresses by the base router 9. The ‘3700 can be accessed at http://192.168.100.200 10. If all goes well, log into the ‘3700 and in the Maintenance area save the current configuration to a file on the computer, just in case. Sorry if the formatting of this reply is one big block of text, it's a browser issue with the computer I'm using.
Yes, thats is the case. The provider sent me a CBN-CH6640E modem, which is also a wifi-router. I want to set the '3700 as an Access Point to connect my devices in the upper floor via LAN and Wifi.

OK, but I have a question about point 1:
I can't log into the base router. When i type in 192.168.100.1, i'm redirected to a page with some information, but i can't change the settings, i think it's blocked by the Internet provider. Also, there's no information about the DHCP server settings, but cause my wifi devices i connected i know some IP's were are possible before (e.g. 192.168.0.30 and 192.168.0.96) do you think thats enough to "guess" that the DHCP range is 192.168.0.XX ?
And another question about point 7:
You mean i must connect a LAN from the '3700 to a LAN from the base router? That could be the reason i failed the last time doing it, because i connected the "Internet"-port to a LAN port of the base router!!!
Edit:
I am able to login, i just didn't find the option before...
:smileysurprised: :smileylol:
Is that the the right information?
Hello,
It’s not exactly mandatory to reduce the DHCP range of the router, the purpose is simply to avoid the risk of the router allocating the same IP address that the ‘3700 is using to another device. Cable modems often have a reduced DHCP range anyway, e.g. 30 devices. So if you set an IP address for the ‘3700 high in the range you might be OK.
I notice in post 8 that you gave example IP addresses in the 192.168.0.x subnet, not the 192.168.100.x subnet. Are you absolutely sure about the subnet that the modem uses to allocate IP addresses? The best way to check is with a single computer connected to the modem, then power cycle the modem, check the IP address allocated to the computer.
It is in fact possible to set other Private IP subnets to the ‘3700 is AP mode e.g. you could set its IP to 10.0.0.1, however this would make it inaccessible using a computer that has been allocated an IP from the modem subnet. In that case all you would need to do is to temporarily set a static IP for the computer e.g. 10.0.0.2 and you could then access the ‘3700 admin pages, then afterwards set the computer back to dynamic.
So, you really have quite a few options when setting the IP of the ‘3700.
Some routers have a dedicated AP mode in their firmware options, certainly newer models like the R7000, and I believe maybe even the WNDR3700v4, this allows the use of the WAN (Internet) port to link back to the gateway router. Otherwise without a dedicated AP mode, one of the LAN ports has to be used.
Hope that helps.
