How to disable wireless on Verizon FiOS Westell 9100em and use personal router device

smart84 2,446 688 June 8, 2012 at 12:43 PM
I have Verizon FiOS Internet which has Westell 9100EM cable modem + router in one device. Recently I have observed that wireless signal from this device deteriorates if my laptop or streaming device is about 15 feets away. (I get around 15Mbps down speed when my laptop is sitting next to the device, and get only 3Mbps when sitting about 15 feets away from the device).

I did not had this type of issue in the past with my linksys router device.

So I am thinking to turn Wireless OFF from Westell device and use my linksys router to provide wireless in home.

I know how to turn wireless OFF on Westell device, but not sure what procedure I need to follow to turn internet ON thru linksys router device. Can someone please help on this?

Thanks a lot in advance!

You sure something is not blocking the wireless signal. Maybe your FiOS router is in a different place than your old router was.

As long as the FIOS router allows you to turn off wireless, then just give the Linksys router a static IP address in the same network as the FIOS, disable its DHCP server, and patch it to a LAN port (LAN to LAN) on the FIOS router. Anyone needing wireless access connects to the Linksys SSID and is dropped on the FIOS router’s network. Simple.

I think I should have stated that this problem is mostly from day # 1 (started FiOS about 8 months ago) but I recently paid attention to it. My FiOS is in bedroom and couch in my living room is about 15 feets away from the device, and I see a major download speed drop and also able to see signal getting 3/5 bars on laptop.

You mean to disable DHCP server on FiOS, correct? Should I enable DHCP on Linksys router?

Shouldn't I connect FiOS LAN port to Linksys WAN port instead of LAN port on Linksys?

Well it depends on your intent. If your intent is to ONLY switch wireless to the Linksys and otherwise continue using the FIOS for DHCP, its network, etc., then you need to convert the Linksys into a simple WAP (wireless access point). And that requires disabling the Linksys DHCP server and patching it to the FIOS router, LAN to LAN.

But like many networking problems, there are multiple solutions, again, depending on your intent. For example, many of these combo modem+router devices can be placed into "bridge" mode, which demotes it to strictly a modem (no DHCP server, no wireless, etc., just a modem). And like any other modem, you patch it to your own router (LAN to WAN, respectively) to create your local network.

Or you could leave the FIOS router as is, except disable its wireless and connect it to the Linksys, LAN to WAN (as you suggested). ***BUT***, now you've created a second network downstream of the FIOS network. IOW, now you're double NAT'd. It's not that it won't work, but it unnecessarily complicates your network topology. For example, now you have to port forward both routers' firewalls. And things like UPnP requests from clients may fail since these aren’t normally propagated beyond the first firewall encountered. Again, it would otherwise work, but it's generally considered poor form because of the issues I've mentioned. Btw, if you do it this way, you also have to make sure each router is using DIFFERENT networks, e.g., 192.168.1.x and 10.1.1.x.

Aaaaah this is getting complicated for me laugh out loudlaugh out loudlaugh out loudlaugh out loudlaugh out loudlaugh out loud

Let me explain what I want to accomplish, and this may give you a clear idea to answer my problems bounce

1. Verizon FiOS: I want to use it just like a regular internet modem.
2. Linksys Router: I want to use it to provide wired internet connection (for my HP network printer, home desktop, VoIP phone adapter) and wireless internet connection (for my laptop, roku streaming player device).

If I convert Verizon FiOS device as a modem, will I be able to use their LAN ports for wired internet connection to other devices besides connecting Linksys router device?

Thanks again!

I have no idea if your particular FIOS device supports "bridge mode". Some combo devices do, some don't. That's just something you need to investigate. But if it does, then you switch it to bridge mode and connect its LAN port to your Linksys router's WAN port (just like you would in any situation where you had a separate modem and router). NO, you can NOT use the other LAN ports on the FIOS router at that point. It's now ONLY a modem and therefore it’s only valid to have a single connection between that modem and your Linksys router's WAN port!

I believe it does support bridge mode but I will double check once I reach home this evening. So once it's in bridge mode which LAN port will be enabled? My guess is port # 1 only on FiOS device and other LAN ports will be forced shut-down by FiOS device firmware?

What eibgrad first posted is the easiest solution. Just follow what he said in that post and you should be good.

Each device may be different in this regard. It may require use of a specific LAN port, it may accept any LAN port. The problem is not really which LAN port is used. The problem is if more than one device attempts to make a DHCP request for the public IP on the FIOS router. IOW, once the FIOS router is in bridge mode, all DHCP requests propagate up to the ISP for a public IP assignment. But since your ISP most likely only allows a single public IP to be assigned per account, THAT'S the problem w/ having multiple devices connected to the FIOS router in bridge mode. You don't want that to happen. So you limit your usage of the FIOS router to only one LAN port.

OK sounds like I need to investigate which LAN port on FiOS device I should use to connect it to WAN port on Linksys and then I should follow this steps:

1. Connect FiOS LAN <-> WAN Linksys ports.
2. Disable Wireless on FiOS and turn the device into bridge (need to verify it supports bridge mode)
3. Configure Linksys router to enable DHCP and wireless security settings.

I think I should be good to go if all above steps work. Correct?

Yes. And most likely it won't matter which LAN port you use on the FIOS router because if you had an ISP that supported multiple public IPs, it would be valid to connect multiple devices on the FIOS router in bridge mode. Each would get a public IP. We're limiting ourselves *logically* to one LAN port because we KNOW our ISP does NOT support multiple public IPs.

Great! I will try to set this up tonight and will post updates.

Thanks a ton for your input worship

I spent couple of hours on yesterday afternoon to disable router and DHCP on FiOS device and enable them on Linksys router but things got messed up. Internet totally got out of service on FiOS and Linksys wired/wirelss respectively. Also assigned unique static IP address to both devices. FiOS network was running in bridge mode, but still did not work. For now I gave up on setting my own router until I know fixed steps to get it to work Smilie Thanks for your all suggestions worship
