For well over a month now I've been trying to fix our internet and I've done everything to try and fix it.
I've replaced the wireless adapters in all computers around the house, I've replaced our router, I even had our ISP come out and give us a completely new line and yet we still have slow download speeds.
It's a 10mbps line with TWC and I'm only getting about 2mbps with perfect upload speed.
These are results I got from running tests:
Client System Details
OS data:: Windows 8.1, Architecture: x86
Flash Info: Version = WIN 16,0,0,287
Your PC is connected to a
Cable/DSL modem
This connection is network limited 93.91% of the time
Cable modem/DSL/T1 link found.
Link set to Full Duplex mode
No network congestion discovered.
Good network cable(s) found
Normal duplex operation found.
Web100 reports the Round trip time = 126.46ms
the Packet size = 1460bytes
2 packets retransmitted
142 duplicate acks received
66 SACK blocks received
The connection stalled 2 times due to packet loss
The connection was idle 1.27 seconds (12.70% of the time)
C2S throughput test: Packet queuing detected: 8.23%
S2C throughput test: Packet queuing detected: 8.23%
Web100 reports TCP negotiated the optional Performance Settings to:
RFC 2018 Selective Acknowledgement:
ON
RFC 896 Nagle Algorithm:
ON
RFC 3168 Explicit Congestion Notification:
OFF
RFC 1323 Time Stamping:
OFF
RFC 1323 Window Scaling:
OFF
The theoretical network limit is 88.09 Mbps
The NDT server has a 90.56 KByte buffer which limits the throughput to 11.19 Mbps
Your PC/Workstation has a 62.73 KByte buffer which limits the throughput to 3.88 Mbps
The network based flow control limits the throughput to 4.23 Mbps
Client Data reports link is T1
Client Acks report link is T1
