Windows Problems Connecting to internet via U-Verse RG 3801 HGV

Windows Problems connecting to internet via AT&T U-verse RG (Residential Gateway) 3801 HGV.

We have discovered that certain versions of Windows has trouble getting an internet connection via the AT&T U-Verse RG 3801 HGV Residential Gateway. It took our Engineers many hours to figure this mess out! And with No help from AT&T!

The symptoms are as follows:

When rebooting or cold starting the Windows PC the internet was not available only a local connection to RG 3801 HGV. This would happen 99.7% of the time. It did not matter if the connection type from the PC was Ethernet, Wireless, static, or DHCP. This was a real issue and pain to say the least.

I am sure many Windows users have the same problem and no way to solve the problem. All AT&T could offer; was to get a newer Windows OS and or newer computer! Really! What kind of answer was that? People pay good money each month for internet service from AT&T U-Verse and that is the best their TIER 2 Tech support could offer up?

We have the fix for you, just follow these steps:

Get a pencil & paper ready!
Using any web browser, Login to the RG 3801 HGV:
http://192.168.1.254

Click the “Settings” TAB
Now Click the “Broadband” TAB, the following will be displayed:

U-Verse 3801 HGV Broadband Settings

We have marked the above image with two (2) red arrows, simply write down the complete primary DNS IP Address and the Secondary DNS IP Address on the paper you provided above.

You can now shut-down the web browser connection to the RG 3801 HGV.

Next we need to modify the DNS settings for your wireless or ethernet connection in Windows. Please see the diagram below for the proper settings:

Windows Network Settings

Notice we have set the DNS Settings for our Windows Network to use the same DNS Servers that the RG 3801 HGV uses.

Of course your DNS IP Addresses for the Primary and Secondary will be different for the general area you are located in, but if you copied the two (2) Addresses correctly from the RG 3801 HGV, then you should be able to enter them in your windows local network or wireless network settings under IPV4 Proprieties.

Important to note, it is ok to obtain an IP Address Automatically, but make sure you check “Use the following DNS server addresses” and then fill-in the ip addresses you wrote down.

Now click Ok and your settings will be saved! That’s it, now windows can access the internet instantly after a cold boot or restart!

Fix Your Slow Internet Access – Wi-FI Problems SOLVED

HughesTech Labs:

Fix Your Slow Internet Access, if you use Wi-Fi for your Internet Access and for no apparent reason it becomes very slow or just un-useable, then check this out:

Did you know that the wireless Telephones most people use around the house or office operate in the same Frequency Spectrum that is also allocated to the Wi-fi band of frequencies? Of course not, most people don’t.

Here is a real-life scenario; My Son was using his wireless Xbox 360 and started complaining to his Mother that the Internet wireless provided by AT&T’s U-verse RG 3800HGV-B (2Wire) wireless router was super slow, she was also on her laptop seeing the same results.

Of course they confronted me with their problem, which I was not seeing while using a LAN connection to the RG 3800HGV-B Router.

So I walked upstairs to my Son’s room and had a look around, there it was, in plain sight an AT&T Wireless house phone sitting about 2 feet from the XBox 360. I removed the phone and put it back where it belonged (down stairs) and the Wi-FI Problem was SOLVED.

REALLY, was it solved? I was curious as to why my Wife’s laptop was also slow, when the problem was in the Kid’s room.

I checked the RG 3800HGV-B Router’s status page and noticed that the wireless was getting almost 100% in errors while the wireless phone was near the Kid’s Xbox 360.

This FIX of moving the wireless phone to another location also fixed the Wife’s slow Internet Access. So not only did it cause problems with the Kid’s Internet Access, it was a Wi-Fi wide problem for all users.

So the moral of this story is, MOVE YOUR WIRELESS TELEPHONES away from Wireless Routers, Laptops, video games and anything that uses Wi-Fi.

This should really FIX a ton of Wi-Fi issues people are having.

Att U-verse Static IP Setup RG 3800HGV-B (2Wire)

HughesTech Labs:

Setting Up the AT&T U-verse RG (Residential Gateway) 3800HGV-B (2WIRE) with Static IP Addresses. Login to the RG using any web browser at 192.168.1.254

If AT&T Supplied you with a block of Static IP Addresses, then you want to navigate to Settings>Broadband>Link Configuration

You must be logged in using a password, the default password is located on the bottom of the RG unit. 

In our case we were assigned by AT&T a block of 64 Static IP Addresses. Our Engineers set the Upstream MTU to 1492

Broadband Link Configuration

Set your Gateway Static IP Address (AT&T Provided) and the Net-mask AT&T provided. Do Not Enable the Auto Firewall Open!

Before you click the save button, make sure your servers and client machines have all been set with a static IP address from the block that AT&T provided and are connected via a Ethernet switch or hub to one of the LAN ports on the back of the U-verse RG unit.

Here is the secret to getting the RG unit to detect each machine (Computer/Server) with a Static IP.  Our Engineers found that the RG unit would take hours or days to detect the different machines.

Simply click the save button on the Link Configuration page and navigate to Diagnostics>IP Utilities

Traceroute IP Addresses

Simply select Trace-route, enter the Static IP Address for the machine/computer you want the RG unit to detect. Next click the start button, once the reverse look-up displays, click the stop button. You must repeat this for all Static IP Addresses that you assigned.

We know this is a pain, but still better than waiting hours or days for the RG to detect your machines/computers on your LAN.

Now that you have detected all your Computers, servers etc., we will show you how to let the Internet community see your web servers etc.

We have Linux servers on our LAN and we set the MTU on all servers to 1480, just seems to work better with the RG unit.

Firewall settings for our system, you may select something different (use at your own risk).We found that the following settings on the RG unit worked best for our Internet servers:

Navigate to Firewall>Advance Configuration

Uncheck Stealth Mode, Uncheck Block Ping and Uncheck Strict UDP Session Control

Next we unchecked the following:

Excessive Session Detection

TCP/UDP Port Scan

Invalid Source/Destination IP address

Packet Flood (SYN/UDP/ICMP/Other)

Invalid TCP Flag Attacks (NULL/XMAS/Other)

Invalid ICMP Detection

Miscellaneous

Next click the save button. (Again use at your own risk)

Last and final phase, navigate to LAN>IP Address Allocation

scroll down the page, you will now see all your Machines/Computers listed, to give each machine full access to the Internet, you will need to do the following:

Device: unknown0010E00233EC

Current Address 99.31.171.155
Device Status Connected Static IP
Firewall
Address Assignment
WAN IP Mapping

You need to disable the firewall so that your  severs will work like a normal ISP:

Device: unknown0010E00233EC

Current Address 99.31.171.155
Device Status Connected Static IP
Firewall
Address Assignment
WAN IP Mapping

Now click the save button, repeat these steps with all machines….

That’s it, your servers/computers now have full Internet access, make sure you have DNS entries for all machines.
