hi folks, I was wondering if any gurus in here could shed some light on why I'm only getting a transfer speed of 5mb/sec (approx 45-50Mbps) on the wireless network below comprised of an older (but very fast), rock solid M6700 Dell Workstation and a newer Asus Q324UA laptop using a Linksys EA6350. Setup below:
1. Dell M6700 Workstation with Windows 7 Pro with Intel Centrino Advanced N 6205 a/b/g/n wireless card , driver Date 6/16/2013, v 22.214.171.124 , provided by Microsoft)
Looks like Dell has a slightly newer driver, v 126.96.36.199, A06 Release date 10/23/2013 but I'm afraid of installing this version as I don't believe the wireless on this Dell is the problem, see below, further details; UPDATE: I just installed this latest driver but the system did no take it, so still back to the older driver).
2.Asus Q325UA (UX370UAR) with Windows 10 Home with Intel Dual Band AC8260 wireless card. (Driver Date 3/19/18, v 188.8.131.52, provided by Microsoft)
3. Between them, I have a Linksys EA6350 router with latest firmware, supporting both 2.4 and 5ghz.
The 5ghz is set to mixed/auto (802.11n and 802.11ac) and both laptops are connected on this 5ghz protocol.
For testing purposes, the laptops are near the router such that I have max connectivity, 5 bars on the Windows 7 laptop and Link up-speed is 300Mbps but Utilization is only 15% on a transfer, Dell to wireless router to Asus.
On the Asus laptop, the "Connection Type" is 802.11ac, but the transfer is 45Mbps.
If I force the router to only use 802.11ac, then the older Dell Windows 7 cannot connect to it, because it's only supporting the N protocol as the best protocol. So I'm leaving the router to "mixed mode" for the 5ghz connection.
Per article at
Setting netsh interface tcp set global autotuning = disabled and restarting both laptops, I now show on both laptops: "Receive Window Auto-Tuning Level" = disabled.
Further, on Windows 7, I can turn off the Advanced "Large Send Offload (IPV4)" -- disabled under the Windows 7 laptop but I cannot find this on the Windows 10 Home Edition network advanced properties.
I suspect that since the Asus Windows 10 Home edition connects to 802.11ac but the Dell Workstation connects to 802.11n, there must be something with the router that may slow the connection, even though the router has the latest firmware applied.
So far, I can only get a 5mb/sec transfer between these two laptops (approx 50Mbps) which I feel is suboptimal.
Any thoughts on how I could increase the speed?
Thanks much for any thoughts,
P.S. hi folks, a quick update: I've connected both laptops to another network 802.11n, the router very close, and while both laptops (windows 7 and Windows 10) show being connected at 300Mbps (Link Speed), again, I could still only see an approx 45Mbps transfer rate between the two laptops.
