Different ways to optimize your internet

Want an optimal connection to the internet?  Speedguide has an excellent analyzer.  Remember don’t just use a benchmark to analyzer your connection.   It is good to look at all aspects of your connection.

You can run their analyzer and see if you need to tweak your connection.   Remember set a control by using a benchmark such as before you begin then tweak with TCP Optimizer

http://speedtest.net/

http://reviews.cnet.com/internet-speed-test/

http://www.bandwidthplace.com/

http://testmy.net Note: This is the best way to TRULY test your bandwidth


Then run:

http://www.speedguide.net/analyzer.php
Example (above)

After reading the recommendations, use TCP Optimizer .  Windows 7 users must right click and run as administrator after saving this file.  This file runs stand alone and is not installed.   TCP Optimizer makes a backup that you can restore if you forget your settings.

Optimizing your network speed with netsh

While this post is for advanced computer users, it shows the inner workings of how an internet connection works.

Disable Remote Differential Compression (Many users state this speeds up file transfers and network transfer speeds – although many question this)

To Optimize your internet connection –

From a command prompt (administrator) type the following commands –

netsh int tcp set heuristics disabled
netsh int tcp set global rss=enabled
netsh int tcp set global chimney=enabled
netsh int tcp set global autotuninglevel=restricted
netsh int tcp set global congestionprovider=ctcp
netsh int tcp set global ecncapability=disabled
netsh int tcp set global timestamps=disabled

To return to your default settings, go to a command prompt as an administrator and type –

netsh int tcp set heuristics default
netsh int tcp set global rss=default
netsh int tcp set global chimney=default
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global congestionprovider=default
netsh int tcp set global ecncapability=default
netsh int tcp set global timestamps=default

So what is heuristics?  Windows Vista/7 has the ability to automatically change its own TCP Window auto-tuning behavior.

What is RSS?  The receive-side scaling setting enables parallelized processing of received packets on multiple processor.

What is Chimney?  TCP chimney offloading enables Microsoft Windows Vista or Windows 7 to offload all TCP processing for a connection to a network adapter.

What is autotuning?  Uses a fixed value for the tcp receive window. Limits it to 64KB (limited at 65535)

__________________________________________________________________________________________

If you have trouble navigating to sites and time out to Facebook or Microsoft for example, or you want to improve your download speeds -you may need to set your MTU settings –

So what do you set your MTU to?  Normally your MTU is set to 1500.   Every connection is different.  First log into your router if you have one and set it to 1492.  Retry the sites that are timing out.  If this did not work, you may need to set the MTU on your network card.

You can go to a command prompt (as an administrator with elevated privileges) and type –

netsh interface ipv4 show subinterface

(to see the name of your network Interface – it is important to write down the MTU settings and network interface name at this time)

To set the MTU value to 1492, type the following command at a a command prompt (Note: You MUST substitute the name of your network connection  –

netsh interface ipv4 set subinterface “The Name of Your Connection” mtu=1492 store=persistent

Many users have reported an increase in download and internet speeds after adjusting their MTU to 1492.  This setting may not be the optimal setting everyone.

Find your optimal MTU using Ping.

Connect to older SAMBA servers and older network devices (Article on NTLM)

Enable NetBIOS over TCP/IP

Disable LLMNR from the command line (Database connections and moving large files across a network)

Drivers and Firmware for the Microsoft Surface

Need to get the latest firmware and drivers for the Microsoft Surface series?  Here’s the link on where to get the drivers and firmware and how to install them through PowerShell.

While the Surface will get its drivers and firmware through updates, you may need to put the drivers on in order to get the updates.   An example of this was my Surface would not connect to our wireless unless I put in a static IP address.   The surface needed an update for the wireless controller.

I downloaded the drivers to a folder on the main drive of a desktop and copied them into a folder on the Surface.   I found the wireless driver and manually installed it.   Once I installed it, I was able to connect to get updates.   To go ahead and install the drivers, I followed the blog link on Microsoft and then I wrote the PowerShell script and placed it in the folder with the drivers.

Note: Microsoft does push these drivers and firmware through updates.

Here’s how to install the drivers –

Setting up a wireless repeater with DD-WRT and Tomato firmware

So you can’t cover your home or business with an adequate wireless signal. Here’s what you can do.

You can purchase a wireless router at local thrift stores for under $10.  When shopping for routers, look for Wireless N routers and try to find a router that supports tomato or DD-WRT.

A mixed network

I decided to put tomato on my main router and DD-WRT on my second router.

First Router Setup

The first router I setup with tomato, setting a SSID, turning on QoS and setting wireless security.

Tomato

Second Router Setup

  1. Set your computer to a static IP of 192.168.1.3.
  2. Connect your computer to the second router by one of the wired LAN ports.
  3. Open the address http://192.168.1.1 in a web browser.
  4. Click on  the Wireless -> Basic Settings tab
    • Under the Physical Interface Section, set the following
      • Wireless Mode : Repeater Bridge
      • Wireless Network Mode : Must Match Primary Router
      • Wireless Network Name(SSID) : This should match the first router exactly including exact the letter case
      • Wireless Channel : Match the first router’s channel
      • Wireless SSID Broadcast : Enable
      • Network Configuration : Bridged
      • Save

    • Under the Virtual Interfaces Section
      • Click on Add
      • Wireless Network Name(SSID) : Make this different from the first router’s.  Although you will connect to either, setting roaming under the advanced settings to aggressive on your laptop or other devices  will help your device go to the strongest signal.  (you should remember each connection)
      • Wireless SSID Broadcast : Enable
      • AP Isolation : Disable
      • Network Configuration : Bridged
      • Save
        Wireless Basic
  5. Click the Wireless -> Wireless Security tab
    • Physical Interface Section
      • Security Mode : Has to match the security on the main router- You must set the security to WPA2-AES
      • WPA Algorithms : Make it the same as the first router
      • WPA Shared Key : Make it the same as the first router
      • Key Renewal Interval (in seconds) : Leave the at the default
    • Virtual Interfaces Section (note if you don’t see this section your firmware should be atleast v24-sp2)
      • Security Mode : Must Match Physical Interface
      • WPA Algorithms : Must Match Physical Interface
      • WPA Shared Key : Must Match Physical Interface
      • Key Renewal Interval (in seconds) : Leave default
      • Save
        Wireless Security
  6. Open the Setup -> Basic Setup tab
    • Connection Type will be: Disabled
    • Set STP for Disabled (Enabled sometimes can cause connection problems)
    • IP Address : 192.168.1.2 (Assuming Primary Router IP is 192.168.1.1)
    • Mask : 255.255.255.0
    • Gateway: 192.168.1.1 (again assuming Primary Router IP is 192.168.1.1)
    • DHCP Server: Disable
    • Local DNS: 192.168.1.1 (if IP of Primary Router is 192.168.1.1)
    • Assign WAN Port to Switch : Optionally enable this to use the WAN port as another LAN port.
    • Save
      basic setup
  7. Log back into the router at it’s new IP address of http://192.168.1.2
    • Open Setup -> Advanced Routing tab
    • Set Operating mode to “Router”
    • Save
      Adv Routing
  8. Open Services
    • Disable Dnsmasq
    • Save
      Services
  9. Open the Security -> Firewall tab
    • Uncheck all boxes…except Filter Multicast
    • Disable SPI firewall
    • APPLY Settings
      firewall
  10. Reboot the router.
  11. Once you have it working, go to the wireless security tab, and set the same type of security AND key for both the primary and the repeater ssids and hit apply. Avoid WPA2 Personal MIXED, as it will likely kill communication between the routers (see Security section below for more on this). WPA2 Personal is fine.
  12. Set your wireless back to auto

The router should now be connected to the main router.   This will extend your wireless across your home.  Why?   Your router is more powerful than wireless cards and can ‘reach’ the main router.

Wireless Surveys/Spectrum Analysis
It is important to perform a wi-fi survey so that you can determine not only the perfect place to locate your access point or bridge but to gain an understanding of the channel co-existence challenge you may face.  With wireless access points in surrounding neighborhoods and businesses, you will need to  perform a survey by walking around and mapping out the BSAs (Basic Service Area) of wireless that surrounds you and your organization.

Below is an example of our school’s perimeter.  Matt, Chris and James, students in the Computer Information Technology, class performed a survey using a Microsoft GPS and Vistumbler.  This survey revealed access points and their channels of current wireless at our institution and  includes APs in surrounding businesses and neighborhoods.  These were mapped using Google Earth after exporting their KML file from Vistumbler.

This type of survey allows IT professionals to analyze data exported to ensure the correct channels can be used at their organization.

Miller Goodroe Felts

After exporting the wireless information, you can analyze each access point or wireless device by clicking on it.  Below is an example of the information exported into Google Earth.   Each device shows SSID, Network Type, Mac Address, Channel, Security, Encryption Type, Data Rates, Latitude, Longitude and Manufacturer information.   Analyst using this information can also determine the best placement of wireless devices along with channel information.

ESSID Expanded

Channel co-existence is when access points share channels that are very close to one another.

802.11 wireless on 2.4 Ghz has three non-overlapping channels.  These channels are 1, 6 and 11.  The closer channels are, the more likely interference will take place.  With the amount of wi-fi in use today, IT professionals have to chose between 2.4 Ghz and 5 Ghz and and try to select channels that are not in use if possible.   Professional access points and bridges can also adjust power as necessary.   A dense population can make this very challenging.

If you look at the students’ survey by zooming out to see how many access points can be seen, this is what you are looking at!  Now you can see why site surveys are important at your organization.

Exploded

In addition to this survey, a secondary survey using a spectrum analyzer is very important to search for interference from other sources.  (See our review of the Airview Spectrum Analyzer)

Netgear Used in the above repeater/bridge modification
The Netgear WNR2000v2 is an excellent router to modify if you want a router that supports DD-WRT.  Although the router has reached its end of life, you can modify the router by flashing it with DD-WRT.   How much did I pay for this router? $3 at a thrift store.

Flashing with DD-WRT

  • Flashing with DD-WRT – Link
    • You must flash with .chk file first
    • Flash of .bin file must be <4mb
    • Follow the instructions thoroughly
      • After flashing with the initial and the firmware, you can upgrade the firmware again here.

The router can also be modified with antenna wires from an old laptop screen and wireless card.

A few freeware picks from an excellent source

First, go visit Rick over at What’s On My PC.  An excellent blogger I have followed for years, Rick can find some of the best freeware out there. Here’s just a few picks of some really good software that he’s featured.

Win Network Tools (from his November 30, 2015 post) –

 “If you manage a network, Win Network Tools may be helpful. The program provides a graphical interface (or launcher) of common command line tools that are built into Windows (that are typically run from the command prompt) and some other options (such as Speed Test) that will launch a site to test out your connection speed.”

Wireless Dropping? Change your Scan Valid Interval

Is your Wireless dropping?  Update your driver of course and then try changing your Scan Valid Interval.   By default, most wireless cards are set to 60.   This is the amount of time before your wireless ‘looks’ for other access points (for roaming).   Try changing the interval to 120.

Open the device manager, double click on the wireless adapter, under advanced, click on Scan Valid Interval – change this to 120.   If you have a card that has roaming under advanced, select the lowest option.

1 Device Manager

 

2 Scan

Note:  If you have a laptop and are moving around in an area, you may need to lower this number.

Also, you may want to lower the Beacon Interval in your router if your signal is low or if you have drops.  This sends beacons more frequently and can help with your signal.   This may slightly decrease your bandwidth (wireless) and use a little extra battery on mobile devices.

While the default is 100, did you know if you increase this time (assuming you have a great signal in your home or business) that you can increase wireless bandwidth (slightly) and even increase your battery life of devices?

Got Atheros? Follow this link to drivers.

Also, do a quick survey of your entire home.  As you can see, one side of our house has interference on channel 11.   Because the ‘user’ of the other wireless is using Channel 6 + 10 (40 mhz ) spread, Channel 6 and 11 are NOT optimal.  Therefore, channel 1 is the optimal channel (you can see two devices – my AP and printer)

Left – host computer  Right – TightVNC into another computer in my home.

Avoid Wireless Interference

Remember, router position and direction matters.  As you can see below, repositioning the router got rid of “Saw Tooth” (signal that goes up and down).

Tomato Cache Optimization with DNSMasq and DNS Benchmark

Want to speed up your internet’s resolution of websites?  One way is to flash your router with Tomato (Tomato is Linux core firmware for many routers that provides advanced features.) or other open source firmware.  Below is an example of how to cache DNS queries using Tomato’s firmware.

So what is DNSMasq?

DNSMasq a lightweight DNS, TFTP, PXE, router advertisement and DHCP server. It is intended to provide coupled DNS and DHCP service to a LAN.

Dnsmasq accepts DNS queries and either answers them from a small, local, cache or forwards them to a real, recursive, DNS server. It loads the contents of /etc/hosts so that local hostnames which do not appear in the global DNS can be resolved and also answers DNS queries for DHCP configured hosts. It can also act as the authoritative DNS server for one or more domains, allowing local names to appear in the global DNS. It can be configured to do DNSSEC validation. ~Read more at –http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html

So how can you make the internet faster?  During name resolution, your router can act as a small DNS server with DNSMasq.  Optimizing the cache and webpages will resolve almost immediately.

First, download DNS Benchmark from GRC and find the fastest DNS servers in your area.

Next, click on Basic and Network.   Enter the DNS servers that you found best for your area.

Click save when you finish.

Next click on Advanced and enter the following information under Custom Configuration.

cache-size=2048
log-async=5
#strict-order

By default, 150 queries can be cached by default but with dozens of devices in homes today, this allows for 2048 queries (below).   The maximum is 10,000.

Once you click enter the information, click on save.   To fully flush the DNS information, reboot the router and on your computer, go to a command prompt as an administrator and type ipconfig /flushdns.

Note:
For Mac OS X El Capitan, Mavericks and Mountain Lion, go to a terminal and type:
sudo killall -HUP mDNSResponder
For Mac OS X Yosemite, type:
sudo discoveryutil udnsflushcaches

To verify my settings, I connected by telnet into the router.  (I also changed my cache to 4096 on my router).  If you decide to telnet into your router, you will have to enable telnet on the router and add telnet to your computer under program and features (you will have to add telnet).

By typing cat /tmp/etc/dnsmasq.conf, you can verify the information was programmed into the router.

Want to make sure your router is answering and resolving names?  Go to a command prompt and type nslookup http://www.microsoft.com.  You should see your router and the IP address information for the domain.

nslookup

You can also see the mail server for the domain by typing something like this –

nslookup
set type=mx
