![]() Motherboard is the only thing that's left out. This problem is clearly beyond OS, Drivers, WiFi card, Antenna and Router (yes tried with multiple routers at multiple locations). Not every connection problem is a result of weak signal strength. My Lenovo on the other hand worked really well with the swapped antenna and WiFi card. ![]() What are the odds of new and old antenna and new and old WiFi cards to be faulty? So this time I swapped the antenna and WiFi card (one at a time) with my Lenovo to really isolate the issue. Installed Ubuntu alongside Windows, still no notable improvement. This made me really curious about the root cause. I tested it by plugging into a different machine (Lenovo Ideapad 320) and it worked really well. Next I suspected the antenna and replaced it with a new one. So I replaced it a better one (Intel AC 7260) hoping it will solve the problem. I always thought it's the stock WiFi card that's creating this problem. Since I was an early buyer of this model, I didn't find much info on this back then. I see that many other users of 5447 complaining about the same on Dell's forum too. I can also see the signal dropping in the taskbar. It works totally fine within 2m of the access point, anything more than that makes the WiFi extremely slow (less than 2Mbps). My machine always had poor WiFi reception ever since I bought it. New/Current WiFi card: Intel Dualband Wireless AC-7260 In both cases, a lack of dense obstructions between the AP and the device will help, especially when using 5GHz channels.Original/Stock WiFi card: Intel Dualband Wireless AC-3160 If the device is not mobile, advise the subscriber to move the AP closer to the device. If this device is mobile, advise the subscriber to move closer to the AP when using high bandwidth, such as streaming video. Also determine when (i.e., how long ago) the subscriber had the poor experience and look at that portion of the graph, selecting other Timespans if necessary. Determine which device the subscriber was using during their poor Internet experience and select its device tile from the WiFi page.Troubleshooting Weak WiFi Signal Procedure While this image depicts an overall healthy connection, your subscriber complaint scenario graph would be marked by multiple troughs in the throughput and signal strength during the timeframe in question. ![]() The data rate later jumps to 65 Mbps with no appreciable difference in signal strength indicating that the device simply moved closer to the gateway and was able to achieve a higher WiFi data rate. However, at approximately 10:43am, the device comes back online with a data rate of 12Mbps while the signal strength remains good (anything above 50% is usually sufficient for good throughput). In this case, the pink line (data rate, read against the left axis) and the blue line (signal strength, read against the right axis) both go to zero. Consider this display:Īt approximately 10:41am, the device turned off or left the network, so there's no signal at all. This is both to conserve power, especially for mobile devices, and to free up WiFi bandwidth for other devices that may need higher data rates. For example, many devices go to a low-bandwidth mode when not in use. Second, the AP or the device may voluntarily select a low bandwidth mode if no higher bandwidth need is detected. The signal strength decreases as it passes through walls and other objects some objects, like metal cabinets, might block the signal entirely. A clear line of sight from your router to your devices provides the best WiFi signal. It has nothing to do with available bandwidth between the AP and the system on the Internet being accessed by that device. To resolve poor wireless range or a weak WiFi signal from your NETGEAR router, try the following: Move your router. In order to effectively troubleshoot WiFi issues, the following two concepts need to be understood.įirst, WiFi Data Rate is only the available bandwidth between a device and the AP. In the second case, the subscriber is using a mobile device such as a tablet or phone and temporarily moved it to a location or orientation with poor signal. In the case of set-top-boxes, gaming consoles, printers, thermostats, and other such devices, the signal strength is not always easy to observe on the device itself. In the first case, the subscriber has placed the device needing high bandwidth in a poor signal area. Two general cases cover most scenarios here. If a device has a weak WiFi signal at the AP (even if the device is showing strong reception on its own display), then the throughput will still be low.
