Not found an IP address.
Not found an IP address.
Hi, your question is clear and well thought out. I’ve recently bought an RE650 range extender and it’s functioning perfectly. Yet I’ve noticed that while all the devices in my home—computers, smartphones, etc.—connect smoothly, my Note 9 keeps showing a connection failure because it can’t find an IP address. It will eventually connect after several attempts, but it’s frustrating to have to do this daily. I’m aware of various workarounds, like assigning a static IP, but I’m curious about the potential downsides of doing that. I’ve read about the differences between static and dynamic addresses, but I still don’t understand why my phone is affected differently or what problems might arise from setting it to a static IP. Also, I’m wondering why most phones aren’t configured with a static IP to avoid this issue altogether. Any insights would be greatly appreciated. Thanks!
I explored this topic earlier while trying to resolve a comparable problem. What I recall: Dynamic IP addresses function by letting your device check which IP addresses are currently used on the network. Your device then selects an available one so you can join the network. You shouldn’t have two devices sharing the same IP on the same network. Setting a static IP ensures your phone always uses that fixed address, regardless of the Wi-Fi network you’re connected to. If you attempt to connect to a public Wi-Fi or someone else’s network where that IP is already taken, your device will fail unless you switch to dynamic IP or manually change it to an unused one.
Unfortunately, I don’t understand why your phone is experiencing this problem with your WiFi connection. I just wanted to remind everyone about the drawbacks of using a static IP address. Maybe another member of this forum can suggest a fix!
The router allocates IP addresses to clients using the DHCP pool it manages. The assigned dynamic IP is reserved for a specific duration, after which a fresh one is provided to the same device. Initially, static IPs aren't required at the device level. You can assign an IP based on the device's unique MAC address through the router. Most home routers support this capability, which prevents you from manually updating the static IP when relocating to a different wireless area. Additionally, certain client devices may struggle with particular routers or range extenders. Since your phone is the only one affected, it’s likely a device-specific issue. Upgrading its firmware or software could help. Personally, I prefer avoiding range extenders. If they’re necessary for your needs, testing by disabling them temporarily can reveal if the problem persists.
Sure, I can expand on that first point. Let me know if you'd like more details. It seems like the issue might be specific to your Samsung device, which could be different from others in your family. I understand range extenders aren't a flawless fix, so it's possible something unique is affecting yours.
Check the router's web interface to discover where IP reservation is managed. You may also transfer the reservation from the client list on the router. The remaining family members likely don’t rely on iPhones, do they? Which wireless configuration is your router currently using?
You're asking about which settings apply to the device. The user mentions one iPhone user and others with Android devices, including Samsung phones. Clarify if you want details on specific settings for iPhones or Android phones.
