Reboot The Router, Refresh NetworkWithout changing anything in your phone and router settings, this is what you’re going to do before digging further into the problem.
- Power off or unplug the router from the power source. Leave it off for 5 minutes while you do the following in your phone.
- From the Home screen, tap the Menu key.
- Choose Settings, then touch Connections tab.
- Tap WiFi.
- Touch and hold the network you’re connecting to then tap Forget Network.
- Go back to Connections tab and turn WiFi off and stay on that page.
- Going back to your router, plug it back into the power source and wait at least 30 seconds.
- Once the router has fully booted up, turn WiFi on in your phone and let it detect the network.
- Connect to your network.
- Now, try to browse to see if the internet is working. Continue browsing to see if it drops after several minutes of use.
By the way, ZDNet published a report today saying that Samsung acknowledged that there is indeed an issue with the Galaxy S4′s WiFi connectivity, although it didn’t go into details. On the same report, D-Link also said they are no researching deeper into the problem as a “limited number of customers has reported connection issues.” With both companies acknowledging the problem, Galaxy S4 owners could expect updates that will fix this compatibility issue. But it seems like there’s more problem on Samsung’s side than D-Link’s.
Some of our concerned readers emailed us that the following could also remedy the problem.
Update The RouterFirst off, this procedure is risky as you might end up having a bricked router. However, for those who can follow simple instructions and have the courage to proceed, here’s what you need to do:
WARNING!!!: You must have a machine connected to the WIRED LAN port of the router to perform this upgrade. Do not attempt to upgrade the firmware over the wireless interface.
- Unplug your router from the power source and find the sticker underneath it. Find the H/W label to know if it’s revision A (A1) or B (B1). You can actually do this without unplugging the router but we want to make sure you are safe.
- Download the latest firmware for your router. These are the links for: Revision A | Revision B. You will be downloading a zip file so you need to extract its contents to a directory you can easily find or navigate to.
- Launch a web browser and open the gateway address: 192.168.0.1
- If you haven’t changed the default password, then you just have to leave the Password field blank and hit the Login button.
- A D-Link page will open. Find Tools tab and click on it.
- To the left, find Firmware and click on it.
- Scroll down a bit to find the Choose File (when using Chrome) or Browse (Firefox)button. Navigate to the directory where you extracted the content of the zip file you downloaded awhile back. There is only one .bin file in there.
- Once you’ve selected the file, hit the Upload button and hit OK.
- You will be redirected to a page showing the progress of the update.
- Once it’s completed, powercycle the router then try to reconnect with your Galaxy S4.
If all else fail and updates from Samsung or D-Link is nowhere to be found, you might want to consider replacing your router with a new one. You know what I mean.
