My family has been having a strange problem with our home network. We have found that we can connect to our Trendnet router for more than a few minutes at a time (on laptops and desktops with wireless cards) before the connection is dropped. The router is always well within range (always displaying 5/5 available bars), but is only sometimes connectable. Sometimes computers will be completely disconnected from the router, while other times it will simply say the network has limited connectivity.
Initially, I suspected this was a router issue. I figured that there might be a configuration proble with the router. So I reset (by unplugging the power) the Trendnet router to its default settings. I left it on its most basic settings: no encryption to access the router... dynamically assigned ip addresses... etc
This did not solve the problem. The disconnecting still occured.
Then I suspected it might be a hardware problem with the router, though it was only a year old. To check this, I bought a brand new Amped Wireless router from Micro Center. I configured this router to its most basic settings, as with the previous router. The second router still had the disconnect problem. Like the old router, we could establish a connection for a very brief period of time before the router would drop the connection entirely. Unlike the old router however, once it dropped the connection, we couldn't connect to it again. In order to connect to the internet, we have to reset the router (again, by unplugging the power). Resettting the router only temporarily fixes the problemm. Like I said before, we only get a few minutes of wireless internet upon each reset.
I think this establishes that it IS NOT a router problem.
Now then... still something seems strange to me. With both routers, I am able to establish a reliable internet connection by plugging an ethernet cable into one of the 4 available ethernet ports. When using an ethernet cable, there are no problems. I do realize that this is a physical switch that basically eliminates the router from the network configuration, but it's strange because the router is clearly NOT the problem. I would have assumed that plugging directly into the modem would give me similar connection problems, but this is not the case.
Summary of above: I can connect to the internet reliably via physical link between my laptop and the modem, as well as my laptop and BOTH routers.
Last bits of info about my network:
ISP: Time Warner Cable (cincinnati area)
-we have a business class internet connection, easily getting 30 Mb/s down, and 6 Mb/s up
Modem: Brand new Arres model... (this can operate wirelessly, though that option is disabled)
Routers: Trendnet TEW-639GR ... Amped Wireless R10000
1. Dell Laptops
4. Dell XPS desktop computer
FINAL BIT OF INFORMATION: (perhaps an important clue that might help solve the problem)
With the Trendnet router plugged in, the apple devices were almost ALWAYS able to establish a connection to the internet. Though the connection to the internet was inconsistent and slow-loading at best, it would maintain this connection. The windows devices (DELL computers) would all disconnect or display limited connectivity, and would not be able to download any webpage. WITH ONE EXCEPTION: we were almost always able to make a google search.
I also bought new ethernet cables to ensure it wasn't a physical layer issue...
Does anyone have an idea as to how I might diagnose and fix this problem?
