Windows 7: Unstable Latency to Router

Unstable Latency to Router

I've recently moved into a new house, and we had our internet connection installed today. However, from my laptop (I've tested on my house mates), I have odd spikes in latency when pinging the router.

In an attempt to solve this I've moved the router to transmit on an empty channel, as well as checked that the router firmware is up-to-date, and my wireless card drivers are up-to-date.

I've attached my IP config (which is 2 images stitched together as it is kinda long), as well as a picture of ping attempts to the router. It's worth noting that wile I was pinging the router for the picture I didn't attempt any browsing, but if I do attempt to change webpage, it can jump to over 1000ms.

Apologies for the double post, but I have some new stuff that might be helpful:

I ran a test using the ISCI Netalyzr, and these were the restults

Direct TCP access to remote FTP servers (port 21) is allowed.

Direct TCP access to remote HTTP servers (port 80) is allowed.
Direct TCP access to remote POP3 servers (port 110) is allowed.
Direct TCP access to remote RPC servers (port 135) is blocked.
This is probably for security reasons, as this protocol is generally not designed for use outside the local network.

Direct TCP access to remote NetBIOS servers (port 139) is blocked.
This is probably for security reasons, as this protocol is generally not designed for use outside the local network.

Direct TCP access to remote IMAP servers (port 143) is allowed.
Direct TCP access to remote SNMP servers (port 161) is allowed.
Direct TCP access to remote HTTPS servers (port 443) is allowed.
Direct TCP access to remote SMB servers (port 445) is blocked.

Network Access Link Properties +

Network latency measurements (?): Latency: 170ms Loss: 8.5%
The round-trip time (RTT) between your computer and our server is 170 msec, which is good.
We recorded a packet loss of 8%. This loss is very significant and will lead to serious performance problems. It could be due either to very high load on our servers due to a large number of visitors, or problems in your network. All the packet loss appears to have occurred on the path from our server to your computer.



TCP connection setup latency (?): 200ms +


Network background health measurement (?): 18 transient outages, longest: 1.0 seconds
During most of Netalyzr's execution, the applet continuously measures the state of the network in the background, looking for short outages. During testing, the applet observed 18 such outages. The longest outage lasted for 1.0 seconds. This suggests a general problem with the network where connectivity is intermittent. This loss might also cause some of Netalyzr's other tests to produce incorrect results.



Network bandwidth (?): Upload 480 Kbit/sec, Download 770 Kbit/sec +


Network buffer measurements (?): Note +


HTTP Tests +

Direct probing of DNS resolvers (?)
Your system is configured to use 5 DNS resolver(s).
The resolver at 8.8.8.8 can process all tested types. It does not validate DNSSEC. It does not wildcard NXDOMAIN errors.
The resolver at 194.168.4.100 could not process the following tested types:
  • Large (~3000B) TXT records fetched with EDNS0
It does not validate DNSSEC. It does not wildcard NXDOMAIN errors. The resolver reports a number of additional properties. Show them.
The resolver at 194.168.8.100 can process all tested types. It does not validate DNSSEC. It does not wildcard NXDOMAIN errors. The resolver reports a number of additional properties. Show them.
The resolver at 128.243.46.113 is not responding to requests.
The resolver at 128.243.42.59 is not responding to requests.

I have also attatched some test restults from pingtest.net.
