First TiVo can see the second, but not Vice Versa

[jayfest]

I haven't found this exact problem in this forum before, but if it is here somewhere, please redirect me.

My PC can see both my S2 and my TiVoHD.
My S2 can see both my PC and my TiVoHD.
My TiVoHD can see my PC but NOT my S2.

What could cause this? This only started happening recently and it is not true 100% of the time, maybe 75%.

Reboot the two TiVos.

Reboot the two TiVos.

Wouldn't hurt to force a few connections to tivo, either.

If all else fails, reboot the network and then restart each TiVo.

I think I tried rebooting one time and the problem was not there afterwards. I agree that would probably be at least a temporary solution, but it does not explain the problem. I'll have to see if it recurs. Rebooting is a nuisance and I don't see why I should have to do it repeatedly (but see below). If there is some underlying cause why my machine can't see the other one, I'd rather fix that condition than have to reboot my DVRs every few days.

Or...

Is there some Conventional Wisdom that says you should reboot every so often anyway, similar to the CW that says you shouldn't let your computer go more than a few days without rebooting?

Update: I have new symptoms.

I went to my HD before rebooting and there in the Now Playing list was my S2. So I quickly went into the S2 NP list and scheduled the transfer of two shows, the first of which started transferring. I went back to my HD and watched some other show, then when I went back to the NP list there, the S2 was NOT showing, even though my To Do list on the HD shows the two shows I ordered to be transferred are still on the list (with my S2 shown by name on the TD list), and the first show is still transferring. So now it appears that it's not that my HD can not see the S2, but only the NP list on the HD isn't showing it. This is starting to sound like a bug.

Actually, it sounds like you have a LAN issue. Are you using wireless? If so, are you using the TiVo-branded adapters?

[jayfest]

Hmm. I did recently change routers from a 802.11b to 802.11g. The transfers have been going faster, including the ones I mentioned above. My S2 is using a wireless, non-TiVo adapter (which always worked fine with my -b router). My HD is wired. But even when my HD can't see my S2, I check the S2 for connectivity and it always says "excellent", generally in the 80%-90% range. And the PC has always been able to see the S2. I suppose it's possible that it could be an intermittent LAN problem that I'll just have to live with until I get around to getting a new adapter (not in the forseeable future). I never felt the need to spend $40 or $50 for a TiVo adapter when a cheap one always worked.

I never felt the need to spend $40 or $50 for a TiVo adapter when a cheap one always worked.I've noted a very significant improvement in performance using the TiVo-branded adapter. Keep in mind that there is TiVo-specific circuitry in the adapter.

[jayfest]

I believe you. Although I'm sure it could have been better, I've never really been that unsatisfied with the performance of the cheaper adapter before, or even with the -b router. I really only bought the -g router because I needed a router anyway for another location and I figured I'd use the -g with the HD TiVo and the better computer and switch the -b to the other location.
