Batch File to Maintain Wireless Connection

This is a Windows batch file and a hack for working around intermittent wireless disconnects. If your connection periodically goes to “no internet access”, this script may help. Obviously, it would be better to find and fix the problem but this may keep you going until you do.

This seems so easy that there must be something wrong with it, but I don’t know what that is yet, so I don’t promise anything. It works for me and I can even keep a putty session going with this script running despite frequent intermittent disconnects.

My script figures out the default gateway and the SSID. It pings the default gateway and upon failure, it will reconnect using the SSID. Then it waits 30 seconds and starts over.

I came up with this script after finding plenty of scripts that were pretty close but not quite what I wanted. Some required that you figure out the default gateway and/or the ssid before running the script. Some required the name of the interface. I wanted something that didn’t require my input.

This will open a command window. The command window reports when a reconnection was required and also allows you to hit a key to bypass the 30 second wait period for one round.

@setlocal enableextensions enabledelayedexpansion
@echo off
for /f "tokens=3 delims= " %%a in ('netsh wlan show interfaces ^| findstr "^....SSID"') do (
set ssid=%%a
for /f "tokens=13 delims= " %%a in ('ipconfig ^| findstr "Default.Gateway.*[0-9]"' ) do (
set gateway=%%a
ping -n 1 %gateway% | find "TTL="
if errorlevel 1 (
goto :reset
) else (
@timeout /t 30
goto :loop
time /T
netsh wlan connect %ssid%
@timeout /t 60
goto :loop

Take a Look at These On Line Scams

This screen popped up after I clicked on a link on Reuters. It looks like an official page from Adobe, telling me I have to install the latest version of Flash. It is not. At the bottom, there is a disclaimer telling us what it is:

We are not affiliated or partnered with Adobe […] This offering is for a download manager that will install independent 3rd party software that will update the advertised program.

Flash Scam
I do believe that if I download and run the installer, it will in fact install the latest version of Flash. I’m sure it will also install applications that deliver a steady stream of popup ads. It will probably hijack my browser and prevent me from using Google, instead delivering a bunch of paid-for results whenever I try to search for something. It might do even worse than all that.

But it looks so real. Here’s another example.

This is a page from Sourceforge, a big repository for open source projects, and it’s the Sourceforge page for Xming, a server which allows you to run Linux X applications from a remote server on a Windows desktop. It’s OK if you have no idea what that means. Xming isn’t the problem. The problem is those “Regular Download” and “Premium download” buttons on top. They have nothing to do with Xming and almost nothing to do with Sourceforge. Those are part of an ad. The real download button is the green one closer to the center of the screen. If you click one of the buttons on top, it will take you to another page where you can download another malware installer like the one disguised as the flash updater.

So why Doesn’t Sourceforge do something about these scammer ads on their website? Probably for the same reason I don’t do anything about the ads that may appear on this blog. We don’t see them. In my case, I have nothing at all to do with them. Whatever ads appear on this site are delivered by WordPress, not me. In the case of Sourceforge, they’re just renting space out to Google Ads, and Google Ads is probably working with other companies. Sourceforge has about as much to do with the scammers as your mail carrier does to the scammers who send junk mail to your door.

At any rate, they’re getting trickier out there. They’re doing a good job making their spamware and spyware installers look official, so be sure to double check what you’re clicking on before downloading anything.

My Upgrade to 8.1 is Not Going Smoothly

Update 2013 October 29: And the solution is here:
To summarize, if you can’t get online after upgrading to 8.1, or if you can’t get online from certain access points, then this might be the solution: Click the link, search for “Kyle”. Read Kyle’s answer then read the paragraph that starts with, “Hey Kyle! You are the man”. Choosing the Broadcom driver worked for me.

Here’s what happened after the original post: As I said in the original post (below), I refreshed the laptop. That dropped me back to Windows 8.0. I waited until I was at school with some free time before trying to upgrade again, so if it failed again I would be able to use a school computer to chat with a tech. It failed again. This time, the tech said, “Unfortunately, the driver for Windows 8.1 isn’t available [from Acer]”, and suggested that I download the latest driver from Broadcom. But I couldn’t find the latest driver on Broadcom’s site. What I found was a forum reply from August


Is there a driver that works properly for Windows version 8.1 preview 64 bit.

for BCM57780

Can you please provide me the link to the correct 64 bit driver?

I am always getting disconnects etc



Sorry, no drivers yet for Windows 8.1, they won’t be available until around the time the OS is available at retail. If you’re having problems with the in-box driver then report it to Microsoft so they’re aware of the issue.


So I used Kyle’s suggestion and seem to be up and running with 8.1.

Below is the original post.

I upgraded from Windows 8 to Windows 8.1 because Windows Store offered the free upgrade in a big purple tile. Then I couldn’t get on-line as school, and I ended up refreshing Windows IAW advice from Acer’s tech support.

Update to Windows 8.1 for free

I started the upgrade while at school but it took so long that I paused it and finished it at home. Everything seemed fine until I got back to school the next day.

Although I could get online at home, I couldn’t get an IP address from either of the schools’s networks. I tried a few things on my own, asked advice from friends, and then spent an hour or so with Acer in a couple of different sessions over two days. The tech in the last of those sessions gave up and advised me to refresh the laptop. That’s not nearly as bad as wiping your hard disk and reinsalling everything, but it’s still a pain. Refreshing saves your files and re-installs the original configuration plus your Windows Store purchases, but you’re on your own for re-installing any programs you got outside of Windows Store.

The refresh took me back to Windows 8.0, and I will try to upgrade again. I’ll let you know how it goes.

First day with a Win 8 laptop

I ordered and Acer E1 with a third generation (aka Ivy Bridge) Intel i5 processor and Windows 8. It arrived yesterday. Almost certainly, I should have waited a couple of weeks longer as prices are likely to keep falling through August, but ordering the laptop was the only way to stop myself from obsessively checking for deals. If you want a laptop with a 3rd generation processor, the first weeks of August are probably the best time to buy, if you look for deals. My laptop has a 3rd generation i5 processor, 4 gigs of RAM, and a 500GB hard disk, and I got it for $399 plus shipping (after a mail in rebate) from Tiger Direct. It does not have a touchscreen. Prices are falling so dealers can make way for the 4th generation (Haswell) processors. If battery life is important to you, you might want to pay the extra money and hold out for a Haswell.

Acer Aspire E1-571-6837 3rd Gen i5, 4GB, 500GB, from Tiger Direct: 449.99, 399.99 after Rebate

While looking for deals, don’t get tricked into buying a 2nd generation (Sandy Bridge) chip or older. If you get a great price on an older chip and it’s what you want, that’s fine, as long as you know what you’re getting. The generations are marked by the first number after the dash. My chip is an i5-3230M, and it’s the first “3” that designates the generation. Also don’t get fooled by a “5” after the dash, followed by two more digits instead of three more. Those are actually older.

The i5 seemed like a good match for me. I’m on too much of a budget for an i7 and I’m not a gamer. An i3 is better for budget buyers who don’t run a lot of intensive applications. Budget buyers who will primarily use their laptops for email should also consider the very low prices available on 2nd generation Intel chips, Pentiums, Celerons, and several others out there. AMD makes comparable chips to Intel. The AMD A8-4500M seems to be at about the same level as the Intel i5. As with Intel based computers, be careful about chip model numbers.

One of the first things I tried to do was load Ubuntu 13.04 in a dual boot configuration, but the Ubuntu setup didn’t recognize the existing Windows 8 installation and wanted to format the disk as if it was empty. There’s plenty of information on-line about working around that problem, just like there’s plenty of information about working around the new UEFI security feature, but the less then perfect installation start and the difficulties I’ve read about overcoming the UEFI feature were the last of a dozen or so reasons that made me decide, for now at least, to leave the laptop configured as a single boot Windows 8 machine. Instead, I installed Virtualbox and loaded Ubuntu on a VM.

So I’m succumbing to Microsoft for now. My first impression of Windows 8 is: I like it. The negative backlash against Windows 8 is wrong-headed but I do appreciate the affect that it’s had on prices.

Windows 8 is surprisingly keyboard friendly. Even though it’s designed for touch, I can hit the Windows Key and then type a command or part of a command, like “chrom” or “word”, and get a list of matching applications. It works better than hitting Alt F2 in Unity or Gnome. I can also navigate the start screen easily with the keyboard arrows, and I can shutdown the system without touching the mouse or touchpad by hitting ctrl-alt-delete, then using the tab key to get the power icon. When using the keyboard is easier in Windows then in Linux, it might be time for a shift in thinking.

Windows 8 results from typing 'word'

I also like the live tiles.

I’m still wary of using Windows as my primary OS. I spend a lot of time fixing bugs and removing spyware from my wife and daughter’s computers. My son uses Linux and I never had to fuss with such problems on his laptop. But I like Windows 8 so far. I like the UI more than the UI of previous versions of Windows and I’ve gotten very frustrated with Unity and Gnome. I’m willing to give Windows another go.

So, so far so good. As of Day 1, I’m happy with my Acer and I’m happy with Windows 8.

Update (same day) I’ve already had to remove adware extensions from Chromium. I was getting ads when I clicked on links, and while poking around the settings found an extension called “tidynetworks”. I removed the extension but I don’t yet know if I’ll have to do more to properly get rid of it. I also had something called webcake and I removed that as well.

GKSU keeps rejecting the password.

If you’re using a Debian based Linux distribution and gksu keeps rejecting your password, try “gksu -S”. If that works, use gconf-editor to make sure “sudo-mode” key under “gksu” is checked.

Cable Signal Loss Causes Modem to Disconnect Router

I’m crowd sourcing this among the three or four people who read this blog. And it might help someone who’s experiencing similar symptoms.

If you’re experiencing intermittent disconnects between your modem and router, it may be a problem with your incoming signal.

It makes no sense to me either, but when my cable modem loses the signal from my provider it disconnects the router. The router’s status changes from “connected” to “connecting”, and of course the modem’s status page is inaccessible from wireless network. What I thought was a problem between the modem and router was actually caused by a poor signal from the provider. It’s a Motorola Surfboard and a Medialink router, but this also happened with a Cisco modem which the cable company replaced and old Cradlepoint modem.

Any ideas why this might happen?

Fixing a strange Graphics Problem with Ubuntu on a Dell Laptop

I’ll just stick this out here in case it helps somebody who stumbles across it. I have Ubuntu on an aging Dell Inspiron. After a while, my display would start getting crappy. The interlaced lines in desktop icons and website images would fall out of alignment, making the image look smeared horizontally. I would also get a pattern of rectangles on my desktop, each made of black or white horizontal lines, so it looked like a sideways barcode label. After a longer while the system would bog down.

The solution was realizing that I had a Mobile Intel® GM45 Express Chipset. Using Ubuntu’s Unity desktop, you can find your graphics information by clicking the gear in the upper right corner and then “About this Computer”. With that knowledge, I searched Ubuntu Software Center for an appropriate driver. I just had to search “GM45”. From there I downloaded the “VAAPI driver for Intel G45 & HD Graphics family (transitional package)”. And that was it! Everything seems to be fine now.

Update Jan 3rd: The fix isn’t perfect, but my laptop still seems to be working much better. The problem has reappeared but the effect is much smaller and the system hasn’t slowed down. The reappearance has given me an opportunity to post a screenshot, which I didn’t think about taking before downloading the driver.

So not perfect, but still a big improvement.

Update (2013 March 14) Like I said, still not perfect. Others with this problem have found that having a mismatched memory sticks may be causing the problem; that is the GM45 chipset doesn’t work well if the two memory sticks aren’t the same. I have 3Gigs, so the problem may be solved completely if I upgrade to 4 or downgrade to 2. I’m probably not going to bother. More info on that here: and here:

Redirecting a Request with Path Information is mapped to my share on totalchoicehosting‘s servers. But users can still type in the address bar and get redirected to the WordPress blog along with any extra path information. So becomes

I do this with a simple index.php in the home directory:

$_SERVER[‘REQUEST_URI’] is everything after the .com. In case the code wraps on your screen, this is just one line of code between the <?php and ?> tags.

But this wouldn’t work unless I ensured that my index.php file would respond to the url with the path info.

To do that, I copied‘s .htaccess file (described here as “genius”, and explained in more detail here), which is found on self-hosted WordPress blogs. This requires Apache’s mod_rewrite.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php  [L]

Without this, would simply return a “page not found” error.

That’s all I need to make the redirect. The redirect only occurs if the request is without any path information or with path information that doesn’t correspond to anything on my share., for example, doesn’t get redirected.

This also seems to work for any feeds that people may have subscribed to before I moved from to There’s no need to create a feed directory on totalchoicehosting, as I described in an earlier post.

I could have just put a self-hosted blog in my home directory and had a smoother effect without the redirect, but I like the convenience of using’s servers. And if they make a little money with ads on my blog then I’m happy to support them, especially if it doesn’t cost me a dime.

I’m messing around with my domain settings

I’m going to map to another server because I’m so much more than just an erudite blogger, I want to have a place under my URL for such projects as my WordPress themes and by blog reader/sharer if I ever get around to finishing it.

This blog will still be under, but no longer under

If you’re one of my countless devoted followers, there’s no need for panic or suicide! I think I can keep the old RSS feeds going by creating a directory on the new server called “feed” and creating an index.php file with the following code:


if(isset($_SERVER['QUERY_STRING'])) {
$url=$url . '?' . $_SERVER['QUERY_STRING'];
echo $output;

So the RSS feed “;, which was mapped to this wordpress blog but will be mapped to the new server, will grab and return the contents from “;. That should work.

I don’t know if email subscriptions will be affected at all, but I think when I select as my primary URL, those will automatically be updated.
