It depends... If your G adapter is getting a good signal, then going wired probably will not help. Did you check your ISP speed?, it could be the lowest denominator. Wireless G has a better penetration (due to lower frequency then N) than N when your router and adapter are far apart (several walls, floors etc). Before doing more work or considering N router, check the signal level on G adapter. If it is good then ideally you should able to achieve about 50Mbs (providing no other wireless device is hogging the channel, which does not have to be your own but can even be your neighbors wireless network). If you live in a densely populated area you see many other wireless networks, it would be a good idea to look for a less crowded channel. But if you do not want to mess with wireless channel settings on your G router, that alone would be a good reason to go wired.
