Connection keeps timing out ( solved

Hey, I’m having problems with my wireless connection, the internet works for all our other comps in my shop, but mine!! It dies out every couple of pages or so and says that my connection has timed out.

So to keep browsing I have to disconnect and reconnect to the internet. Then it times out after a few pages again. It’s HORRIBLE. Every page or 2, I’ve got to disconnect and reconnect!!

I have been researching this problem for weeks and the most logical thing I’ve come across so far is that it is related to either an IP connection timing issue, (which must be resolved by modifying the registry key (http://support. microsoft. com/kb/813827), or it is related to a port blocking issue (which I have yet to resolve.)

The port blocking suggesting makes sense, because some folks report losing access to secure sites (https) and others report losing connection to regular websites (http). I personally can connect to the secure sites, such as my credit union account (https), but lose the http connection after about a minute or two. The only thing that restores the connection is a complete restart, and then it only lasts a couple minutes.

Since internet connections are routed through two different ports, depending on whether it’s a secure or unsecure site, the port blocking concept has a lot of merit. I don’t know how to access these controls or modify them, but I am posting this here because a) someone may know how to resolve the timing/port blocking issue, and b) these are the newest questions regarding this problem. I have found similar questions dating back to 2004, using all versions of the OS, all browsers, all computers and all kinds of routers, with and without firewalls. The problem almost assuredly has to do with an IP setting on ports, connection timing, or both. Help me Obi Wan Kenobi, you’re my only hope.

I have a netgear router from AOL on this desktop which has the normal DSL connection. I have recently bought a Sweex wireless dongle to connect my dad’s comp to the wireless. All installed and says I have excellent reception, however when I load firefox I only get the google homepage and occasionally one other page before it dies – ‘connection times out’ or ‘address not found’. IE wont even connect.

I work for a big for-profit online university, and we see this problem all the time. It’s a big deal for us because we’re for-profit, and when a person can’t attend our school because their HTTPS connections keep dropping, it cuts into our profits.

I’m going to be upfront though; I am not a networking person. I do not have an understanding of TCP/IP protocol.

That being said, I’m pretty sure this is what is happening:
Most wireless connections are encrypted. That is, encrypted while your data is traveling through a radio signal between your computer, and the access point or router, where it is de-crypted, and passed along completely unencrypted through the rest of its journey.

That last part is normal. Wired network connections are NOT encrypted. This is not a problem for the most part, because nodes (the big servers your data hops across on its way to its destination) have SO MUCH traffic moving through them, an unscrupulous employee with a high level of access would have to fish out your data from the stream, and your data is probably no more interesting than the next guy’s data. (Sorry.)

However, it is because of that remote possibility, that we use encrypted secure connections for bank transactions, VPNs, email, and connections to our colleges and universities websites. That way the unscrupulous employee would have to fish out your completely nonsensical data, and spend the next 2,000 years using a supercomputer to figure it out.

So here’s where the dropped or timed out connection comes into play. This is kind of difficult to explain using plain language terms, so techies please bear with me:

First, you have to understand that encryption increases the amount of data you are transferring. Say that you were going to encrypt my name, Seamus. The encrypted version would not be six characters long. The encrypted version could be 60 characters long.

Ever notice how sometimes on a secure site your web browser will say “this page contains both secure and non-secure items. Do you want to display the non-secure items?” You get that message because the web page you’re on does not want to encrypt the transfer of images between you and their server. One little image can easily be equal to the data of all the text on the page. Encrypting the images would make the page load on your computer EXTREMELY slowly.

When you are on a secure (aka encrypted) wireless connection, and you try to access a secure website, you are overlapping encryption. At that point, you are sending a massive amount of data between your computer and the wireless access point. Just a few dropped packets or network interference (even if you have maximum signal strength) can bring your connection to a crawl, or time it out completely.

I agree with post # 11, Online University IT. Before I got my laptop my PC had no trouble at all. My internet connections never timed out. Since I got my laptop and set up my wireless router to be encrypted I now have problems with my laptop and PC both timing out. Now my laptop is connected via a wireless connection but my PC is not and yet I have the same timing out issues on both computers.

The problem started as soon as I set up the encryption on the wireless router and I hadn’t realized that until I read that post. I’m am going to try and remove the encryption and see if my internet connection is better, if so then I’ll have my answer. I guess at that point I will have to avoid doing sensitive work on my laptop, such as logging into my bank account, etc.
