I walked out to the street, about 30 ft from the AP, and the N800 started to see the local neighborhood AP's, and my own 'N' AP. I connected to my N AP without a problem and walked back into the house next to the AP. The N800 maintained a connection. When I tried to reconnect to the N AP while in the house, the N800 went blind again. Walking back out to at least 30ft from the AP allowed the N800 to connect to the N AP. So if I stay far enough away from the N AP, it works. When I get close, if is already connected, it stays connected, but it can't reconnect.

Of course when I switched the AP back to G-only mode, the N800 could connect no matter where I was.

So maybe there is something nearby that prevents the N800 from seeing WiFi. If not an N access point, perhaps something else that
generates enough 2.4 ghz noise to muck up the N800.

All of a sudden yesterday, the N800 started seeing my SSID's and connect fine, though i had to re-scan several times because it wouldn't list them all the time. On the plus side, it has maintained a solid connection for the whole time without disconnecting.

Pheew, at least a start.... I'm finally using it the way it was meant to be.

On a side note, is there a way (or an app) to get a (digital) clock on the top where it is visible all the time? I was so engrossed doing stuff on it that i didn't realize it was 3.35am !!!

Re: N800 - Wifi problem. Cannot detect router at home

My N800 doesn't see all local wifi networks all the time either.

ANd, I'm suspecting my DLINK DIR-655 isn't playing nice when it is in mixed N-G-B mode.

In G B it'll see it. Disconnect. Set to N G B, can't find it. (actually during the router little reset moment, the N800 can't see anything at all) Back to B G, there's my router. Though my laptop won't see it now.... Grrr

I've had similar issues with notebooks not seeing anything and having to do IP configs manually where DHCP isn't getting along. Time to write DLINK.

So, I'm really thinking there's something wrong with the router firmware. DIR-655 1.0.5

... If only I could figure out why Google talk is not able to connect "unable to connect to one or more accounts". On two accounts, password logs in on gmail, so it is correct. Updated skype and microb and fm. (if that matters) Used to work fine before, though I've never actively used it.

It's a confirmed bug on the DIR-655. Mixed BGN does NOT work properly. I bought the same router and had to return it.

Well, better some security than none! :D

Re: N800 - Wifi problem. Cannot detect router at home

Regarding WEP, just use MAC address filtering. Oh, and my $.02 on this whole thing: pre-N sucks. I will not (voluntarily) use until it's an approved specification. Otherwise, look what happens. It's insane. My b/g Linksys router serves me just fine.

Just don't fall into the trap of thinking that MAC filtering is a reliable means of security - it's true it will deter a complete ignoramus from accessing your network, but MAC spoofing will form a part of any half-decent WiFi attack kit because the MAC address of any computer can be changed to match a valid MAC address on your network (of course the attacker would have to learn one of your MAC addresses but that isn't too difficult).

Once I've defeated WEP encryption within about 5-10 minutes it only takes me a few more seconds to change my MAC address and I'm past any MAC filter that might be in place... :)

Re: N800 - Wifi problem. Cannot detect router at home

True. But I guess the point is not to thwart attacks, but to deter them. A home network will never be attacked, except by opportunistic wardrivers. If my neighbors have unsecured WiFi and I have WEP with MAC address filtering, I'm not going to be the one attacked. Of course, I really should be using WPA2 encryption. I suppose I could use that, if I could get Ubuntu and the (future) n800 to play nice with it.
