Comcast Internet Connection drops with SonicWall TZ 150W

Posted on 2011-05-01
Last Modified: 2012-05-11
I have a 2009 SonicWall TZ150W (Firmware SonicOS Standard, ROM SonicROM ) .  The support and download renewals have long expired and it would cost more to renew (3 years retro) than buy a new device. The wireless is causing the internet connections to drop for all users and I have to restart the Comcast RCA cable modem and the SonicWall several times per day!  Now I have a purchasing decision to make and I'm asking EE experts for advice.
Should I buy a new all-in-one router/wireless DOCSIS 3.0 cable modem with 4 LAN ports like the Motorola surfboard SBG6580 and dump the SonicWall?  The reviews of this product online are horrible.  Is there a better "business class" modem I should consider instead?  I don't mind paying more money if it will work well on all technologies, low maintenance and easy to set up.
Otherwise, should I just rent a wireless modem from Comcast?
Who makes the best internet appliances now?
Thanks to anyone that would like to share recommendations.

    In order to help you make a good decision we need to know a few things at least.

    1) How many users do you have on your network

    2) What technologies are you using?

    There is a new SMC Business Class router from Comcast that I have heard good things about. They have been using SMC exclusively for five or so years and they finally have got it right.  The new device is solid from what I hear from people who have received it.  You need to have Business Class Service from Comcast in order to get this device.

    1. I never combine my modem and router.

    I'm still using a surfboard 5100 that was $80 at best buy, with an $80 rebAte for signing up with cox (I cancled the cox I had 5 min before, I love no contracts) and a $75 bestbuy gift card, and 3 months of Internet for $20.

    To be clear, this is a home network so Comcast business service at $99 per month is probably not feasable from a cost standpoint. At home we have 4 users and 3 wired computers (1 MacPro, 1 WinXP, 1 Windows 7 business pro) and 2 wireless laptops (1 Mac, 1 Windows 7 business pro).

    I did install an SMC router and Comcast business service at my small office and the modem works very well.

    You still have not told us what services you use?

    At my house I have a plain old netgear gig router:;jsessionid=87F7938B26F95DDE8A6A3F61BEC77BF1.bbolsp-app04-41?id=1218007383662&skuId=8998506

    I have 4 wired computers, 1 linux server and three wireless laptops and have no issues at all.

    I'm sorry I guess I don't know what you mean by "services."  I'm sorry. I'm not using the SonicWall to access my home computer anymore by VPN so I don't need that, if that's what you mean.
    Anyway, the Netgear N600 looks like it gets good reviews and has 4 ethernet ports.  Will the Netgear router replace both the SonicWall and the Comcast modem?  Do you recommend this?

    I'm sorry was away for a while.

    Well yes if you are not using any special services (VPN, tunneling, etc..) then this NetGear device works well.  As I said I use this at home and it serves up my 8 machines just fine. I probably do some more advances stuff than most people running samba, a web server and SFTP server.

    BTW, The NetGear would replace your sonicwall, not the modem.  You will still need a modem.
