I recently purchased a DIR-825 to replace a dead DGL-4500 (OOP), which ran like a top for years. Setup was easy, and everything ran fine (and we have a LOT of electronic devices) until my wife tried her Acer Aspire One - it linked up quickly and easily (54M/100% signal), but it refused to access the Internet.
I checked the router, and the Acer netbook showed up perfectly, with its own DHCP assigned IP, but again, packets were going out, but nothing coming in. Like the DIR-825 was stopping any and all transmissions to the AA1.
So naturally, I upgraded to the latest firmware - same deal, so I started fooling around with settings, trying all the N/G/A options, then changing all the security settings (WPA 1/2, AES/TKIP) in order, with the AA1 sitting on my desk. Still no change, the netbook linked up quickly and easily, but there was no data coming from the router. Trust me, I methodically used ALL WPA/2/AES/TKIP combinations (Open and WEP are *not* viable options) and there was no change - the AA1 linked up perfectly each time, but no physical access.
We also had two other AA1 devices, with the same Atheros AR5007EG network cards (since upgraded and out of use) I tried those thinking my wife's netbook was faulty, but the *exact* same thing happened with both machines - link up perfectly to the router, but no data coming down the pipe.
I then tried downgrading the router firmware and seeing if a change was made along the way, but again, no change to the outcome. There are also no driver updates for this card on the Acer website past what we are using, and any attempts to update using online drivers has not worked either. I also updated the AA1 BIOS to current and upgraded any other drivers - no luck.
Router Info:
DIR-825 Rev B
Firmware used: 2.03NA, 2.05NA, 2.06NA
Security Setting Tried: WPA/WPA2 and AES/TKIP all combos
Wireless N/G/B Settings Tried: All
2.4/5 GHz Networks active/inactive: all combos
Aspire 1 Network card: Atheros AR5007EG
Security Setting Tried: WPA/WPA2 and AES/TKIP all combos
Now, as I stated before, the router seems to be working and functions absolutely perfectly with the following hardware in our household, so it seems to be a specific problem with the AA1 and/or its Atheros network card:
D-Link DAP-1522 Bridge
Multiple HP, Dell and Toshiba notebooks (G/N)
2x MSI Wind netbook
Dell Mini
Multiple 2nd-gen to 4th-gen iPod Touch
iPad
iPad 2
4x HP Touchpad
2x PS3 Slim (120GB and 320GB)
Xbox 360 Phat (wireless G adapter)
Xbox 360 Slim (integrated N)
Wii
2x DSi
2x DSi XL
4x PSP
2x Wireless HP Printers
Asus O!Play
and probably more I am forgetting.
Everything works perfectly, *except* the Acer AA1's, which seem to link perfectly, and show up in the Wireless list, but are not able to access the Internet/network/any data stream.
I am just posting this as a last-ditch effort to get a potential solution (although I realize there probably isn't one) before taking the DIR-825 back to BB, as I like the router otherwise.
