Re: "Unable to turn on Bridge Mode"

I have the same issue but i was reading that if i have the Bridge enabled, then i am not able to use the current Wi-Fi extenders i have. Is that correct? I work from home and it is creating so many issued with my work phone. I can be on calls and it automatically drops. There has to be a way to fix this without interrupting other services.

@user_a2sqd3 - The "Bridge Mode vs. Wi-Fi Extenders" dilemma is a common one, but we can definitely untangle this. Here is the breakdown of how to handle SIP ALG and your connection setup.

 

1. How to Disable SIP ALG
SIP ALG is intended to help "translate" VoIP traffic, but more often than not, it misinterprets the data and kills the connection. Here is how you can resolve it:

Option A: The DIY Route

- Log into your router's web interface (usually by typing 192.168.1.1 or 192.168.0.1 into your browser).

- Navigate to the Advanced or Security/Firewall settings.

- Look for a tab labeled ALG, NAT, or VoIP.

- Locate SIP ALG and toggle it to Disabled or Off.

- Save settings and restart both the router and your work phone.

Option B: Contacting your ISP If you have a modem/router combo provided by us, these settings are sometimes hidden. We may be able to take a closer look at your account on our end.

 

2. Does Bridge Mode Break Wi-Fi Extenders?
Generally, yes. Here is why:

When you enable Bridge Mode, you are essentially turning off the "router" and "Wi-Fi" parts of your gateway, turning it into a simple "pass-through" modem.

- Because the gateway's Wi-Fi is turned off, your current Wi-Fi extenders (which rely on picking up that specific signal) will have nothing to talk to.

- The Fix: If you need Bridge Mode (usually to use a higher-quality third-party router), you would need to plug a new Mesh Wi-Fi system or a new router into the bridged modem. Those new devices would then provide the Wi-Fi signal for your house.

 

3. The "No Interruptions" Strategy
If you want to fix the phone issues without losing your current Wi-Fi extender setup, try this order of operations:

- Check for "SIP ALG" first: Try to disable this without turning on Bridge Mode. This is the most likely culprit for dropped calls and won't affect your Wi-Fi extenders at all.

- Assign a Static IP: If the phone still drops, go into your router settings and assign a "Static IP" or "DHCP Reservation" to your work phone. This prevents the router from "forgetting" where the phone is.

- Prioritize via QoS: See if your router has a QoS (Quality of Service) setting. You can tell the router to prioritize your work phone's traffic over things like Netflix or gaming.

 

A Quick Tip: If your work phone has an Ethernet port, try plugging it directly into the router (or even an extender with an Ethernet port) using a cable. Hardwiring bypasses many of the "handshake" issues that Wi-Fi introduces.

 

Please let me know if this helps!

My phone is connected directly to the router. When I had this issue on the past, I had to change internet providers and i did not have that issue.  You mentioned "Contacting your ISP If you have a modem/router combo provided by us, these settings are sometimes hidden. We may be able to take a closer look at your account on our end." I tried called and whoever i spoke to had NO idea what i was saying... this has been the most frustrating issue to resolve with xfinity, to the point that i am looking to cancel my account. :( Who can i contact that can actually walk me through this? Thanks!!
