Resolved Ethernet and wifi are producing different speeds

Yesterday, I began to experience drastic speed results with my two computers. The Ethernet-connected Desktop produces normal speed results (~100Mbps) and the laptop is fluctuating but only producing 5-19 Mbps. I suspected a three week old router (NETGEAR R6200v2). I replaced the R6200 router with my old NETGEAR WNDR3400 and it is producing the same, low and fluctuating speeds at the laptop. I did use software:URunstaller to clean the disc on the hard drive, earlier yesterday, on the laptop and suspected that I clean something important off the drive so I did a restore back to December 9th restore point...no help.
Chatted with a tech at my ISP and he suspected the ethernet connection from the modem to the router but, if that were the case, I would think that the Desktop would show the same fluctuations and low speed but that isn't the case. The desktop is a steady 100Mbps.
Any suggestions would be appreciated. Thanks

 

Thanks, TonyT. Would that be the Microsoft Virtual WiFi Miniport Adapter that you are suggesting I delete or uninstall?

 

In programs and features, what specifically should I be looking for to uninstall? Theres a long list of programs, some obviously not what I should be looking for to uninstall but, I don't see a program called wifi drivers. excuse my ignorance

 

Is it the Intel PROSet/Wireless Software?

 

or the Widows Drive Package-Lenovo (ACPIVPC) System?

 

After resetting the Modem and Older Router and with the laptop positioned within two meters of the Router (residing at my desktop desk), I obtain a Download speed of 14.68 Mbps and an Upload speed of 12.19 Mbps, using my ISP's Speed Test web page. The Desktop tested at 85Mbps using the same web service.

 

Hi papernpaste, I think you will find what you're looking for in Device Manager.
In W10, Right click Start button > Device Manager > Network Adapters > xxxxxbrand WiFi Adapter > Right click > Uninstall > OK > close out > Shut down comp > Restart. Neil.

 

Firstly, deleting the network adapters and rebooting, forcing an automatic re-installation by Windows, DOES increase the speeds on the wirelessly connected laptop.

After further research, I've determined that the distance from the router is proportionate to the speeds, received.
If my laptop is carried into the room in which the router resides and brought within a meter of the router, I'm getting speeds close to those received, via Ethernet.

If I carry the router into another room from the router room, the speeds drop off drastically. The makers of routers knew exactly what they were doing when they designed routers with the 2.4mhz systems so that they could up-sell everyone to dual band and 5.* mhz wireless systems and increase their profits. This is all by design, of course. One would need to purchase and "extender" to provide more efficiency between the router and the laptop. It's Capitalism at its finest example.

It's analogous to the laundry detergent manufacturers weakening their laundry soaps, gradually and over time, so that the consumers are forced to purchase "laundry booster" products. It's ALWAYS about the profit at the consumers' expense.

I'm considering this thread resolved.
