3Com's OfficeConnect wireless router brings Internet connectivity to your business. It has the ability to handle (through supplemental switches) up to 253 (64 wireless) simultaneous users. The four 10/100M RJ-45 ports and 802.11b/g functionality make it easy to configure your network for maximum efficiency.

Because security for a business network is at least as important as for a home network, 3Com includes a full suite of features. Wireless clients are protected by WEP and WPA/WPA2 encryption algorithms. The NAT/PAT firewall helps prevent outsiders from hacking into the network. Keyword and URL filtering increase productivity and security by blocking access to certain sites.

  • newegg Wi-Fi Certified The 3com 3CRWER100-75 features compatibility with 802.11b and 802.11g wireless devices to preserve existing wireless network investment, while Wi-Fi certification assures interoperability with similarly certified products.
  • newegg 10/100Mbps Network Connection The 3com 3CRWER100-75 features a built-in 4-port 10/100Mbps Ethernet switch for direct connections to four PCs or additional switches, and one DSL (Digital Subscriber Line) port for broadband Internet connection.
  • newegg eXtended Range Technology With the eXtended range (XR) technology, the 3com 3CRWER100-75 delivers longer range connectivity and single access point coverage for home networks, eliminates dead spots for corporate wireless LANs, and provides an outdoor coverage of up to double the distance of the last generation competing WLAN solutions.
  • newegg Dynamic DNS With the Dynamic Domain Name Service (DNS), access the Internet with dynamic IP addresses to use network applications such as Web or FTP servers that normally require static IP addresses (Subscription with Dynamic DNS providers is required).
  • newegg High Wireless Security The 3com 3CRWER100-75 supports WPA and WPA2 with TKIP/AES and 40/64 and 128-bit WEP encryption for highly secured data transfers on your wireless network.

1 out of 5 eggsThink twice

Pros: They seem to work reliably for many years

Cons: On recent purchase of three of these, the firmware is 1.3S and reject a flash. 3com messed up on the firmware and the update firmware won't flash over. The internet policies don't work, which is what the flash is supposed to fix. One of the releases was for outside the US for a US Router.

Other Thoughts: Trying to get an RMA from 3com requires that the House is in session and that Congress will approve it. It's over a month and I still don't have an RMA from 3com, and they messed it up.

3 out of 5 eggsGood for the average office

Pros: This item offers some pretty advanced firewall features. (You should apply the latest firmware 1.3.06)
Advanced content filtering for all PCs or specific PCs. You can even single out individual PCs by IP address for internet blocking, especially in situations where PCs cannot be directly monitored by supervisory personnel. you can run Virtual Servers for FTP, HTTP, HTTPS and more.

Cons: There is really no apparent way to put in advanced firewall rules or routing. For example, if you see attacks coming from specific IP or range of IPs, you cannot block a specific IP or range of IPs from access, nor can you permit specific outside IPs access to certain network resources. The rules are extremly limited.

Other Thoughts: This unit would be great for a small professional office or factory of 20 or less PCs.

4 out of 5 eggsConnect Directly to Cable Modem--No Hubs In Between

Pros: Once you get it working, the bandwidth, range and stability seems great. The price also seems pretty reasonable. Finally, it has four wired LAN plugs, which alslo worked fine with non-wireless systems.

Cons: Product diagrams suggest that you can connect this device downstream from another switch or hub. I found this not to be the case, at least with the small Netgear Gigabit switch I had been using. However, once I moved the 3 Com Wireless router directly downstream from the cable modem, it worked great. Also, with Vista SP1 32 bit, you may not need the driver CD--Vista seemed to have built in drivers which found the 3 Com router immediately. I had previously tried to install the driver CD but Vista did not appear to do much, if anything, with it (full install wizard never opened). My TymeWarner Cable modem (SE WI, "Road Runner" service) appeared to like the 3 Com just fine. During the install wizard, I selected the option to have the device clone the I-Mac numbers from the cable modem. I selected the option to make the 3-Com router the only device in my system which assigned auto IP addresses. Documentation is pre-Vista, but seems works great with 32 bit Vista Ult on older Dell

Other Thoughts: Documentation needs improvement. Does not receive Wireless N signals, but works well with G in my somewhat rural area.

3 out of 5 eggsVery tempermental

Pros: When it is working, it is EXCELLENT. Don't get me wrong, it usually IS working.

Cons: The problem with this router is that if the cable modem drops the connection, this router is very tempermental when you try to reboot it and the modem. I literally have to reboot both the modem and the router three or four times (5 to 10 minutes of screwing with it) to finally get the net connection to come back. This only happens once every few months, but it does happen.

Other Thoughts: 3com is an excellent company in general, so the name is always good. I always purchased Linksys routers for home applications, but decided to try 3coms router. When this finally dies, I am going back to Linksys with 3rd party firmware (DD-WRT).

2 out of 5 eggsDefinitely not for Console Gaming

Pros: None for me.

Cons: MTU is ONLY (non-adjustable) 312 with Auto IP Detection, can be set to 1500 with Static.

Other Thoughts: Basically this is NOT XBox Live Compatible UNLESS you have a Static IP Address.

3Com shows no interest in fixing this well know/documented flaw.

Avoid this router if you're a gamer.

5 out of 5 eggs3com works

Pros: I have the 3com 3CR858-91 10/100Mbps OfficeConnect Cable/DSL Router model but this is close to it. Used the 3CR858 to replace linksys BEFSR-41 which continued to lock up and got worse.. 1 month and NO LOCKUPS! Thanks NEW EGG! and thanks for all the reviewer who recommend it.. I recommed 3com office connect routers!!!

Cons: limit documentation on each item to setup but can get around

Other Thoughts: Highly recommend the 3com 3CR858-91 10/100Mbps OfficeConnect Cable/DSL Router but if you cant your hands on it.. find one thats close to it.. Im sure this one will do as good or better. Went from a 4.2MB download on Linksys to a 6.2MB download just swaping out to this (3com 3CR858-91 10/100Mbps OfficeConnect Cable/DSL Router) router
