Please feel free to add to this thread, as most of the problems i come across are due to network issues and not the Pronto.

First check the following:-

1,The Prontos and RFX's have the most uptodate firmware, and your using the current version of PEP.

2, The Wireless Access Points/wireless routers are of good quality or on the recomended Pronto list under the FAQ's

3, The AP's have a unique IP address on the net work and only one device should have the DHCP enabled!

4, Make sure if you are using DHCP that the lease time is set to 3weeks, so if you go on a 2 week holiday you wont get any clashies :)

4a. If using DHCP, check the DHCP range on your router and ensure that no equipment on your network is configured for a static IP address in this range.

Most Linksys routers reserve 50 addresses (192.168.1.100-149) for DHCP. One common error is to configure equipment with static IP addresses such that the static IP address is assigned in this range (192.168.1.101, for example).

Doing this can lead to problems when network drops or router is rebooted. DHCP-based devices will renegotiate their IP addresses and if it so happens that they negotiate and lock in an IP address that is used by other static-IP Address-based equipment before the equipment with static IP address reboots/reconnects, the equipment with static IP address will fail to work.

5,Wireless encryption , WEP 64 ,128 , NONE or WPA or MAC address, Start with None! then at least you will know that its working first, then chose the type you want.

6, Wireless Channel number, fist get you self an application to run on your laptop to see what other devices near by are using, i use WiFi spy 2.4x this works very well. Then pick your channel numbers with little or no interferance, if your using more than one access point try to keep the overlap of the signal strength to a minimum and set to to diferent channels at least 5 apart.

7, Read this page of FAQ's on the philips site [Link: pronto.philips.com]

8, If you are using Fixed IP address make sure they are outside the DHCP range!

9, Make sure the SSID is easy to remember , i had an installer call me because he couldn't get his Pronto to connect to the network, i wasn't surprised with an SSID like this " tHe Big_Apple Never r0Ts", it took the installer 3 hours to get it right , use all upper or lower case and spaces or under scores.

10, Make a list of all the devices and there IP address on the network, it will help!

11, Make sure your access point is set to "G" or "B, G" only!

12, Look for help on the "Ping" function on Google, you should get results <23ms from the Pronts, if you can not ping them they are either "asleep" or not connected to the network.

13, IP ranges, Make sure all the devices are in the same IP range e.g 192.168.1.XXX,

14,Use the Diagnostic page with in the TSU , key press "Backlight + Menu + 2nd hard key" this will also show you the IP address of the TSU.


15, If all that fails post on Remote central :)

LRM - Mod Edit - Added 4a which is an error that novice network admins commonly make.

I'm not fond of Airport Extremes. Fixing the Pronto IP addresses increases the likelhood of success.

The WRT54G2's work very well.

gopronto,

I just posted this question here: [Link: remotecentral.com]

Sorry for this lame questions, but I really have to get an Access Point to make this things to work? An Ad-Hoc net won't work?

LRM - Mod Edit - In interest of keeping post count down on this thread, I replied yes on the other thread. An Ad-Hoc net won't work.

I have used many Linksys/Cisco WRVS4400N's with great success.
Found them very stable, never having a problem with the remote connecting, nor having to reset the routers.

As a note, I run them in wireless G mode only, and disable wireless N.

We use Netgear WAG102, seem fine also. Set on B/G except 9300 which seem to only work on B? Fixed IPs for everything.

Dupe...

Thats odd as the prontos are wireless G .

There are many causes for poor wireless connections, and many solutions:

First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbour’s router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.

Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbour’s wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.

In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbours. For example, if you have a strong neighbour on channel 9, try any channel 1 through 4.


Try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.


For wireless g routers, try setting the "Transmission Rate" to 54 Mbps.


If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.

I think you can one more settings on your wireless Router. Login to your Router setup page. Click on Wireless Tab , and Click on Advance wireless Settings, and under that you can change the Beacon Interval to 50, Fragmentation Threshold : 2306 and RTS Threshold : 2307 and click on save settings. This should solve your problem.



These settings gave a new life to my wireless router, signal strength has improved and I do not have to go to another room just to restart the router to get it working again. But can you please tell me what really are these settings and are these optimal or is there still room for improvement.


RTS, Adjusting the "RTS Threshold" can help alleviate Packet loss. If one of the Wireless computers can obtain an IP address but can not ping, then set the "RTS Threshold" to 2304. After changing the value click on the Apply button on the "Advanced Wireless" screen, then a page will appear prompting that the settings were successful, and when that page appears, click on the Continue button .



--------------------------------------------------------------------------------
Beacon Interval
Adjusting the "Beacon Interval" can help association problems. If there is a wireless adapter that is able to see the access point, but is unable to get locked, try adjusting the "Beacon Interval" to 50. After changing the value click on the Apply button on the "Advanced Wireless" screen, then a page will appear prompting that the settings were successful, and when that page appears, click on the Continue button .


Fragmentation threshold
Adjusting the "Fragmentation Threshold" can help association problems. If there is a wireless adapter that is able to see the access point, but is unable to get locked, try adjusting the "Fragmentation Threshold" to 2304. After changing the value click on the Apply button on the "Advanced Wireless" screen, then a page will appear prompting that the settings were successful, and when that page appears, click on the Continue button .

~~~~~~~~~~~~~~~~~~~~~~~~~~


This leaves nothing to do apart from tweaking the advanced wireless settings to marginally improve problems related to weak signal and/or RF interference, so I've been reading everything I can find on these boards and elsewhere about changing Fragmentation Threshold, RTS threshold, and beacon interval. However, I'm left with the following questions.



1) There seems to be disagreement about Fragmentation threshold and RTS threshold settings. Some (including the Linksys Technical Troubleshooting Wizard) recommend that both be set to 2304. I have also seen people insist that Fragmentation be set to 2306 and RTS to 2304. A few recommend 2306 for both thresholds, and some advise 2306 for Fragmentation and 2307 for RTS (though by my limited understanding, it simply disables RTS when the value is higher than the fragmentation threshold value). Which of these settings is best? And more importantly, WHY is it the best? Generally, I understand what the settings do, but I am reluctant to change them when there doesn't seem to be a consensus about exactly what they should be.



2) With respect to beacon interval, I've seen both 75ms and 50ms recommended to replace the default of 100ms. For a network of my size (4 APs, averaging 5 users each), will increasing the number of beacons (and hence the RF traffic even when the network is idle) pose a problem? Also, I'm a little less clear as to how this would improve connectivity.



Since these settings will affect all users, I want to make sure that I'm using settings that will be beneficial on the whole. The last thing I want to do is inadvertently make things worse.

You may also want to search for DLink DIR as I think there is a firmware update from DLink that was required to stabilize lots of things.

Just not sure if it was for the DIR-600.

Hi,

In general my TSU9400 makes good connection with my router.
But the moment the screen of the TSU9400 dims (after 240 sec.), it looses the networkconnection. And then it takes long before re-connect.
The strange thing is, when the TSU9400 is in the dockingstation and the screen dims, the network connection is not lost.
Why this difference in behaviour? And how to change this? I want my remote to keep the network connection when not in dockingstation after the screen dims.

Because, when docked, the Pronto is always awake. When undocked, it goes to sleep when the screen goes dim.

What is your wireless timeout set to? If not twenty four hours, then set it to 24 hours (which is, in effect, the always on setting).

For my TSU9400 I have setup a second, dedicated wap (router) that acts as a switch in my network. DHCP switched off, Pronto has fixed IP. Pronto network timeout is 24 hrs. WPA2 security and restricted access by MAC adress.
It all looks good. The TSU9400 makes fast and easy connection. When the screen dims and I pick up the Pronto, network re-connect is immediate.
But... when I leave the Pronto alone for a few hours, then re-connect does not work. The connection goes on / off / on / off / ... every few seconds.
Resetting the router, then everything works okay again.

What is going wrong?

I read this on the Pronto FAQ: "Note that the Pronto will only connect to a new WAP if it looses the WiFi connection." What does this mean? Is this related to my problem?

you can manually disable and re-enable the wifi of the pronto when it wakes up. Maybe it would prevent the issue.

What does your router's log say? Maybe the pronto tries too many connections and then the router blocks it.
