Netgear DGN2200 connected with Galaxy Tab

[#1]

Just got ebay Netgear DGN2200 v3. Connected with XP PC & Win 7 laptop ok.  Problem with link with Galaxy Tab 1 7". Connection made ok but some of the apps not working saying "no network". Browser, google earth & some of the apps working ok. Got a feeling when I was setting up router I didn't get to the end of network setup. Gone back to previous DG834g v3 & everything working ok.
Is it best to hit the reset button on new router & start again? Would welcome any advice.
Cheers

Unless you can get in easily and finish the network config manually (thus saving what you've done already) that is probably the best bet, though I have to admit I've not used that router before.

Thanks Matt. Will try reset in couple of days. Don't want to bugger my line up as I made quite a reboots yesterday when trying to set up that router. Letting things settle back down for a while on old DG834. Long line, 2.5mb at best so dont want to loose any speed.
