I have a Cloud Router Switch CRS125-24G-15-2HnD-IN connected to my ISP. It is currently acting as my wireless network at my home. Unfortunately, it is spotty in some areas. Would it be better to hard wire an extender (12-57 VDC) or hard wire another Cloud Router Switch to my main router in my attic? I want the wireless network to be the same as the orginal wireless network obviously as opposed to having two separate ones. Any help with configuration would be great.
Thank you

If you want it only (or mainly) for wireless, something smaller than another 24-port CRS would be probably better:

Hard-wire another access point (any wireless routerboard will do, just configure it as AP bridging wireless with ethernet ... without routing/firewalling/nating) and configure it with identical security profile. Devices will then more or less seamlessly roam between both APs. You can even choose a dual-band device and with some luck client devices will transparently switch between both bands.

Would you mind being more specific with each step of the configuration process as described below?:

I guess some of it could be done by selecting correct QuickSet profile. I'm not acquainted to those, so I'll describe a bit harder way:

• Download and install utility called winbox on your computer. It's a windows app, but works fine on linux and OS-X under wine as well
• connect to your AP through one of "LAN" ethernet ports and perform reset without default configuration
• at this point the device won't have any configuration and the only way of connecting is using winbox via MAC
• now create a bridge and add all ethernet and wireless interfaces (CLI commands are the following, in winbox the structure is similar):
  Code: Select all

  /interface bridge
  add name=bridge
  /interface bridge port
  add bridge=bridge interface=ether1
  add bridge=bridge interface=ether2
  add bridge=bridge interface=ether3
  add bridge=bridge interface=ether4
  add bridge=bridge interface=ether5
  add bridge=bridge interface=wlan1
  add bridge=bridge interface=wlan2 # if your device has 2 radios
  

• add basic IP configuration to bridge to make "normal" management connection possible. You can run DHCP client for auto-configuration from your existing DHCP server, preferrably create a static lease for your AP:
  Code: Select all

  /ip dhcp-client
  add dhcp-options=hostname,clientid disabled=no interface=bridge
  

  Or you can statically set IP address etc. Just take care to use bridge as interface.
• Configure wireless (security profile identical to your main AP, radio settings, etc.). Use same security profile for both wireless interfaces if your device has two radios.

At this moment the AP should be a transparent L2 bridge between wired and wireless...

Sorry for the additional questions, but I am not too familiar with the New Terminal command codes. Additionally, are you able to specify which steps are intended for the original router updates and which steps are for the new router?

Also, if you have screen shots of the configs, that would be great. I got lost on some of these steps:
