Lanbench client was running on a Thinkpad P50 laptop, which was using either its built-in adapter, or USB adapter (in the latter case, built-in adapter was disabled). To exclude random errors, we run each of the tests at least twice at different times and averaged the results. We used Lanbench v1.1.0 (which is nothing fancy, but just enough for our purposes). Lanbench was set up with the following parameters: test duration=10s, packet size= 2048. I.e., turned off QoS, Client for Microsoft Networks,Ĭhannel Width: Auto (Only other option is "20MHz Only")Ĩ02.11n Channel Width for band 5.3 or congested Wi-Fi channel, but this is a subject of very separate testingįor the purposes of this test, we measured throughput of TCP connection, over a trivialized WiFi network consisting of one router and one client WiFi adapter.

I cannot figure out how/why this laptop suddenly dropped to 10% of the speed I was getting with Vista. If testing this provides any troubleshooting benefit at all, I can but haven't done it, yet. Besides, it is not the NIC that is crawling and not how I would normally use it. I have NOT tried a hardwire connection to the router because I have never LAN connected this laptop to the router before and wouldn't have a baseline. A lot of the "solutions" did not apply to me (like the lack of Smartbyte or the NIC option of 20/40 Auto). I cannot remember everything else I tried (again, I spent > 4 hours on this) but if it is anywhere in the first 7-8 DuckDuckGo pages, I tried it.

I also reset winsock and ipv4 and ipv6 connections.

Smartbyte was not installed (saw that in a lot of places, including this forum).

I also disabled non-essential Windows services (too many to list) like AllJoyn, Bluetooth, etc.

I downloaded and ran TCPOptimizer ( :: TCP Optimizer / Downloads), also to no avail.

Most of what I tried can be found here (pardon the expletive in the title-not my site): 10 garbage-Easy Ways to Fix Slow Internet on Windows 10 - Saint None of these worked for me.

It is also slower than the upload speed.įor the past 4 hours, I have exhaustively tried every forum "solution" to speed So, the download speed is 16-25x slower than the ISP speed and 9-13x slower than the 802.11g rated speed of 54Mbps. My ISP connection is 100 Mbps download and 6 Mbps upload. All report about the same download speed: 4-6 Mbps!!! The upload speed for each is consistently 5-6 Mbps.

I installed offline w/ all privacy settings turned off (e.g., location, cortana, voice recognition, etc.).Īfter it finished updating, noticing how slow the Windows updates were, I tested the bandwidth speed on and 5 or 6 other bandwidth speed sites (e.g.,, , etc.). Other than installing Chrome and turning off unnecessary services, I have made no other customizations, yet.

All NIC drivers are updated and current (according to Win 10).

The install went well and the Windows updates, while slow, completed w/o failures.

So, I formatted and installed Windows 10. Vista is not supported for the new software.

Well, I needed to install some software on the Vista laptop because it is the only machine I have w/ a BluRay/DVD player.

No other device has connection or speed issues. I have made no router changes in 5 years and my other devices run as expected (another Win 10 laptop, Roku, Amazon Firestick, NAS, etc.). It ran fine for years and the Internet speeds were as expected for an 802.11g connection (~45-55 Mbps download).
