A Fast Guide to Troubleshooting Slow Speeds
Your Sprint Broadband Direct
connection may not be the problem.
When you encounter a web site that is loading slowly, your first
reaction might be to think that the connection is slow. But this may
not be the case.
Sprint Broadband Direct (SBBD) does not connect you directly to
individual web sites; it connects you to an intermediary, the
Internet Service Provider (ISP). All SBBD can do is see that the
transmission from (and to) the ISP goes like greased lightning.
Unfortunately, we can't do anything about problems in other parts of
the Internet or your computer. These can include:
-
Bogged-down web sites - When a web site experiences a very
high number of visitors, it may become unable to respond. You may
receive the message: "The page cannot be displayed" or the web
site will respond, but slowly. You may be able to get to and from
the web site very quickly, but once at the site, processing is
delayed, resulting in what appears to be slow Internet speeds. It
is similar to waiting in a slow grocery store line.
-
Heavy backbone traffic - You may have a network in your
residence or business. When you connect with your ISP, you become
part of a larger network. When your ISP connects you to the
Internet, you become part of the largest network there is, the
Internet, or the information superhighway. You share the same
routes, routers, and backbones with other Internet users.
Sometimes these backbones (the "main lines" through which packets
of data flow over the Internet) get overloaded with traffic,
resulting in slower speeds when getting to and returning from web
sites. It is similar to being stuck in rush hour traffic in a
large city. Sprint is not responsible for the maintenance or
performance of non-Sprint backbones.
-
Faulty or broken routers - Any component on the Internet is
liable to fail. If routers fail, your transmission will be
redirected to another router, but that adds time to the trip. You
have been forced to take a detour. Sprint is not responsible for
the maintenance or performance of non-Sprint routers.
-
Your computer and networking peripherals - If you have an
older computer, the components may not be up to date. The speeds
on the SBBD network may be fine. However, your computer's ability
to receive and process information may happen at a slower rate. If
you are running several different applications simultaneously,
your computer's ability to process rapidly may be compromised.
Also, if your computer is part of a Local Area Network (LAN), the
hubs and routers required by the LAN can also take a bite out of
the Sprint delivery speeds.
Here's a quick rule of thumb: If you can connect quickly to
certain web sites, but notice that it takes much longer to connect
to others, then it's likely that the slowdown is due to factors that
are out of the control of SBBD and the ISP.
Help yourself to faster speeds.
If you are experiencing
across-the-board slow download speeds, you might think your only
recourse is to call SBBD technical support right away. But in fact,
there are actions you can take on your own that could resolve, or at
least clarify, the problem. And no, you don't need an advanced
degree in information technology to follow them. Below, we'll
outline the procedures, most of which are similar to what an SBBD
technical support representative would take you through.

Testing Speeds
Here's an easy way to see whether your download speeds are up
to par. We've devised a speed gauge that will tell you what
your current download speed is. Using it is as simple as looking at
the speedometer on your car.
Click here to use our Speed Test. Within seconds you'll
see a speed gauge in the form of a bar graph, with a box to the left
listing line speeds in Kbps (kilobits per second) and KBps
(kilobytes per second). If the bar in the graph goes into the green,
you know that your download speeds are in the broadband range - that
is, you are getting the fast speeds from SBBD that you signed up
for. On the rare occasions when the bar only extends into the red-
or mustard-colored part of the band, then there is an SBBD download
issue, and you should contact technical support. (There will soon be
an extensive searchable knowledgebase of solutions on the Sprint
Broadband Direct site, from which you can obtain support and answers
for many issues.)

Troubleshooting Slow Speeds
- Temporary Internet Files
Don't Let Them Keep You Waiting
When you browse the Internet, your browser stores various files from the sites you visit, in a folder or folders on the computer's hard drive. Up to a point, the files are beneficial, because retaining these elements can enable a site to load faster. Your browser can pick up part of the web site right from your computer instead of retrieving all the data from the site. Naturally, this makes your connection faster.
Unfortunately, your browser doesn't know what sites you'll be returning to, so it retains every image, header, and piece of text that it can grab and store.
As temporary Internet files accumulate on your hard drive - and they accumulate quickly if you spend much time on the Web - their virtue becomes a liability. The temporary Internet files soon begin to take up space on the hard drive that could be used for more productive purposes. Worse, these files can slow everything your computer does, including downloading from web sites.
There are, however, simple procedures recommended by both Microsoft and Netscape that you can use to recoup valuable storage memory that can increase your download speeds. For additional questions or concerns regarding either browser, please visit their independent sites at http://www.netscape.com and http://support.microsoft.com.
Sprint is not responsible for hardware or software failures that result from the use of recommended troubleshooting procedures provided.
Deleting Temporary Internet Files
To delete temporary Internet files using Microsoft Internet Explorer 4.0
1. On the View menu in Internet Explorer, click Internet Options, and then click Delete Files.
2. In the Delete Files dialog box, click OK, and then click OK again.
To delete temporary Internet files using Microsoft Internet Explorer 5.0 or higher:
1. From the Menu bar in Internet Explorer, click Tools>Internet Options.
2. Under the General tab>Temporary Internet Files, click Delete Files, then click OK in the dialog box that is spawned.
3. Under the General tab>History, click Clear History, then click OK in the dialog box that is spawned. Note: This will remove the items in the History log that provide a trail of each site you have visited, so if you want to retain this feature, skip step 3.
Sometimes the time it takes to delete the files can be lengthy if there are a large number of temporary files.
To delete temporary Internet files using Netscape Communicator 4.0 and higher:
1. Click edit in the Tool menu.
2. Click Preferences.
3. In the Preferences dialog box, click the + sign to the left of Advanced to expand the menu.
4. Click Cache to select it.
5. Click Clear Memory Cache, then OK.
6. Click Clear Disk Cache, then OK.
To delete temporary Internet files using Microsoft Windows:
1. Open Windows Explorer.
Windows Explorer is usually found on the Start menu. If it is not, from the Start menu, click Run, type "Explorer" in the field that appears, and click OK.
2. In the left frame of Windows Explorer, go to C:>Windows>Temporary Internet files (in Windows NT, C:>Winnt>Temporary Internet files).
3. Click Temporary Internet files, and in the frame to the right, a list appears.
4. Hold down Control+A. All the files in the frame to the right are highlighted.
5. Delete them, either by going to File on the Menu bar and clicking Delete on the drop-down menu; by clicking the Delete icon in the toolbar; or by pressing the Delete key on the keyboard.
The time it takes to delete the files may be lengthy if there are a large number of temporary Internet files.
An alternative method using Microsoft Windows:
1. On the desktop, double-click My Computer.
2. Double-click C:>Windows>Temporary Internet Files (in Windows NT, C:>Winnt>Temporary Internet files).
From here on, the steps are the same as 4 and 5 above.
Limiting the Hard Drive Space Available for Temporary Internet Files
You can control the amount of hard drive space on which temporary Internet files are stored. For more information on controlling the amount of disk space used for storing temporary Internet files, direct your browser to http://support.microsoft.com or http://www.netscape.com, and use their comprehensive search engines.
To limit the hard drive space available for temporary Internet files in Microsoft Internet Explorer:
1. In Internet Explorer, click Tools on the Menu bar and Internet Options on the ensuing drop-down menu.
2. In the Temporary Internet Files section, click Settings.
3. In the Setting section, slide the pointer under "Amount of disk space to use" all the way to the left.
To limit hard drive space available for temporary Internet files in Netscape:
1. Click Edit in the menu bar, then click Preferences.
2. In the Preferences dialog box, find the Advanced line in the left-hand side of the box. Click the + sign to the left of Advanced.
3. Click Cache. On the right-hand side of the box, designate how many megabytes of space you want to allot to the cache. Suggested size is 7.5 megabytes, which you enter as 7500 KB.

- Firewalls/Proxy Servers
Your firewall protects
you against hackers. It may also protect you against maximum
speeds. Don't get us wrong - we're big fans of firewalls.
Especially with an "always on" connection like SBBD, it's wise to
have a firewall for security. Unfortunately, there is a tradeoff,
because firewalls can degrade speeds.
If you are part of a
network that uses proxy servers, or shares bandwidth by using
proxy software, this can also apply some drag. If one computer is
assigned an Internet Protocol (IP) address and acts as a proxy
server, it will take the bandwidth of that single IP and
distribute it among other computers using the same Local Area
Network (LAN), and can cause severe degradation and latency - both
of which amount to slow downloads.
You can test whether
this is happening. Disable the firewall or proxy server (if you
need assistance, consult the firewall or server instruction
manuals or contact the manufacturer) and open the speed gauge
again. If speeds have picked up significantly, the firewall is a
likely suspect. If not, go on to the next step.

- Requirements
For your Internet connection to be
up to speed, your computer must be up to speed. To get the
most out of your SBBD connection, your computer must meet certain
specifications.

- Registry Enhancements
To see better, open your
window. On a computer running Microsoft Windows, there is
something called a TCP receive window. This basically determines
how much data your computer can receive in a given period of time
before it chokes. If the receive window is too small,
broadband-transmitted data can overwhelm it. Not to worry: we have
a fix for this.
It's called RegEdit (also known as the
Registry Patch). It expands the receive window from the default
setting of 8,192 bytes to 49,152 bytes. To download RegEdit, click
www.sprintbroadband.com/utilities. When the download is complete,
reboot your computer and run a speed test using the speed gauge
again. If speeds have picked up considerably, your problem may be
behind you. If not, go on to the next step.

- DNS Settings
Try a new setting. No, we
don't mean move to a location with a better view. We're talking
about DNS settings. DNS stands for Domain Name System, which is a
program that translates web addresses in words - those familiar
URLs such as www.yahoo.com - into numbers that computers and
Internet routers understand. Your computer needs to know the DNS
server (and the secondary server, if any) for your location. If it
is mistaken for some reason about which DNS server to work
through, speeds will suffer. The best preventative is to manually
configure your DNS settings.
Check out the speed gauge again. Do
speeds look a lot better? If not, go to the next step.

- Bypassing the Network
Shut off the computer and
disconnect any hubs, firewalls, and/orrouters in the network.
(As noted earlier, firewalls and networking equipment can
reduce the overall performance of your Sprint Broadband
connection.) Then, using a crossover cable (the connectors have a
different sequence of colored wires at either end), connect the
Sprint Wireless Broadband Router (WBR) directly to the Network
Interface Card (NIC) of your computer. After powering the
computer, launch your Internet connection and check the speed test
once more. Has eliminating the networking brought the download up
to broadband speeds? If so, consult with your company's networking
manager or the manufacturer or installer of the networking
equipment.
- Power Cycling
Off again, on again. The
next potential fix is to power cycle the Sprint Broadband Wireless
Router (WBR), the device connected to the coaxial cable from the
wall outlet and to your computer, and the transceiver, the dish on
the roof. "Power cycle" is just the technical way of saying to
turn something off and back on. Sometimes that's all it takes. To
power cycle the WBR:
- Shut off the computer, as well as any hubs, firewalls, or
routers in the network
- Disconnect the power cable for the WBR. (All lights on the
WBR will go off.)
- Wait 30 seconds. (Electricity needs to drain from the
circuitry.)
- Reconnect the power cable for the
WBR.
Restart the computer and other hardware that
you shut off. Back to the speed gauge. Is the speed now in the
hot rod category? If not, power cycle the transceiver:
- Disconnect the power cord for the transceiver. Do not
disconnect the coaxial cable from the WBR.
- Disconnect the power cord for the WBR. This will turn off
all lights on the WBR.
- Leave the WBR and transceiver disconnected for 15 minutes.
- After 15 minutes, reconnect power to the transceiver and
then reconnect power to the WBR.
Check the speed
gauge once more. If the bar is in the green zone, congratulations.
If not, congratulations are still in order, because you have
successfully completed the same steps we would have taken you
through during a technical support service call. But, it appears
that the problem will not yield to a standard solution, and it's
time to contact Sprint Broadband Direct technical support. Send us
an e-mail, describing the problem and mentioning the specific
troubleshooting steps you have taken. You can click on the Contact
Support link on this page to initiate an e-mail.
