try a full power down of everything I do mean everything. Power off the computers, the router, the modem etc. leave all power off for 5 mins or so, then power up in this order, power to modem only let it get fully lit up, then power on to router, let it get fully lit up, then power up your computers letting each get fully loaded. Then try to connect to your wireless, I assume you have put in your wireless network passphrase for the laptops that are trying to access the wifi network.

I have enjoyed the disucssions here. I am on the quest to find what I will be able to do in my new RV. The main issue will of course be first getting a wifi signal from something. I do have an ATT air card which has a 5GB cap, I have my cell phone but have the minimum data plan on it currently and they do not offer an unlimited. I have a zyxel portable router that can make a hotspot from a wifi signal. 11n-compatible Wi-Fi router supports DSL/Cable and 3G connectivity, and a unique failover capability; should your wired connection be interrupted for any reason, the MWR222 will automatically switch to a 3G/4G wireless signal via the users Mobile Broadband Adapter modem. So now I have the ability to have enough wifi in the RV to use any of the devices I want to use. but I need to search out other cheap(ha!) sources to obtain an internet signal on the road. I know some places we will stay do provide free wifi and using my own portable router will make that wifi secure, but for those places out in the boondocks that don't provide wifi, I will need some kind of access. My ATT air card at 5GB cap sure won't allow much streaming of anything. Any thoughts? I have been looking at Roku and other boxes and with the usb port I definitely could download plenty of my own content to have available to view for the times I am not able to gain decent access to anything. The RV does have a roof top antenna and it is wired for cable for when we are at a site with cable. I do have direct tv at home and I know they do offer an on the road version to be able to use you current direct tv account with RV direct tv equipment, no idea of additional costs. the zyxel I have MWR222

Possibly. The first thing you should try is moving the existing router around. Sometimes even a few inches of movement can make a difference. Generally speaking you want the router to be up high and free of obstructions around it. The are also, depending on the router, hacks for the firmware that allow you to change the settings increasing, for example, signal strength. You could also look into different antennas for the router. Another possibility is to use a "repeater." While there are devices especially made for the purpose, they tend to be a little expensive. You can use another router, access point, or even some print servers to function in the capacity of a repeater and position it on, say, the first floor somewhere. The last alternative and one guaranteed to work, is to run a length of CAT5 cable between the basement router and your bedroom. Although depending on the layout of your house, that may or may not be easy to do. Another option might be to run CAT5 between the basement and first floor, positioning the router there.

Good point... There is a label above the slot that identifies it as a hdmi port. A number 6 was also identified. I then went back to the external ports option and label video 6 as hd. hd was one of the choices it gave me to use. After that I was able to point the tv to slot 5 and the Roku displayed the first screen. For the benefit of others who might be going down this same path at some time...If the label does not identify the slot then as kudzu9 suggested... simply try each slot in turn until you click on one. The label though makes it a lot easier. Another problem poped up next and this was simply a case of the online Roku install procedure falling a little short of leading a new customer through the process. The install process accurately identify the att wireless name. In case you need to know what your wireless name is... it is, in my case, labeled on the router. After I selected the att choice it then asked me for my password. One would think that they wanted the password that I setup for the wireless. No, not the case... it came back each time I tried saying the wireless could not be located. It would have been helpful if their on screen instructions asked for the router number instead of the password. I found this numeric number also pasted on the router. Bingo... every thing worked and I completed the process. I then had a cocktail and vowed never to install another new system again. Once again I got some very good help from the att support staff as well as the vendor where I bought the tv from. They still had my purchase on line and was able to pull up the manual which helped a lot. Now it is on to looking at the channel lineups and see what is there. Btw, I have now watched 2 movies and the 3 mbps process did not break up once.
