In these cases it may be beneficial to switch off this feature (see below). In worse cases with certain cards, drivers, and infrastructure, such as in the OPs case, the scans can cause noticeable connectivity issues and packet loss. In most cases this results in a few tens of milliseconds of latency every X minutes.
The duration and impact of said scanning varies according to operating system, driver, access point, and card parameters. Background scanning is a normal process and occurs on all cards but it should not be noticeable and definitely should not be causing packet loss. The lags and interruptions appear to be associated with background scanning by the wireless card. I'd like some help as where should I start to solve this problem, like any actual software to extensively diagnose the connection (and do the same to the other machine, to have a comparison), or, if not possible, a different approach to the problem (getting a new ac router due to incompabilities-merely speculation). I have more machines in my network, namely a Toshiba L650-11E (Windows 7 Home Premium 64-bit, with the wireless card being BCM2070 integrated in BCM94313), and it has literally 0 problems with the connection. The second one is a SMCWBR14-GR, which was used getting the Hitron into bridge mode and stopping all its router activity. My main router is a Hitron BVW-3653, which is the ISP modem as well. I've tried updating the BIOS, updating the drivers from Toshiba (which has the policy of publishing the drivers for their own machines), updating the drivers directly from Intel (which were clearly more recent, despite not solving the issue), changing routers and replacing the laptop. The connection is always strong and I'm located in a room with no other electronic devices (to avoid interferences), no farther than 2 meters from the router. Web browsing simply hangs for a couple seconds (YouTube suddenly stops buffering, Facebook loses connection to the server).Online games report ping increase as well, and may show that the connection is loss for the second (CS:GO, LoL).TeamSpeak connection quality reports an increase by 800% (!) in the latency, and the packet loss increases to 30% (note: the server is located on my LAN, so the ping is usually 1 to 2 ms).I use this computer mainly for gaming, and I've noticed that the connection doesn't seem too stable as, every now and then, the connection stutters for a second, causing in-game lag.īecause I lack knowledge of the proper software to diagnose these issues, the only things I can say about the issue, when it happens, are: So, I got a new Toshiba L50-B-103 (Windows 8.1 64-bit, specs) which comes in with the wireless card indicated in the title, Intel® Dual Band Wireless-AC 3160.
