Occasional lag spikes when tethering or something like a lag spike

[Anna'ire]

So while tethering on my HTC TP2 I get occasional lag spikes. This has been going on since day one with my TP2. I'm wondering if this is NORMAL for the TP2 and, if it's normal, if there is a fix available.

For example, when surfing the Internet my internet connection will stop for 1-5 seconds and then it'll come right back on. When playing online games, I do NOT get disconnected but rather lag and then my client lags behind but then catches up after my Internet reconnects in the next 3 seconds.

I noticed that when this happens the data arrows on the notification bars go gray before this happens but then light back up to white after 3-5 seconds and then my internet connection re-establishes.

It happens occasionally and I've noticed it's not just my phone but all 3 HTC TP2's that I have in my house (owned by my family members) including mine.

Help please!
