Wired and Wireless Conflict
I bought a new tp link router to facilitate a new FTTC connection in my small office. Things seemed difficult to set up but I got there. After that sometimes things wouldn’t work correctly. Eventually I sussed that having Wi-fi enabled and Ethernet connected was the problem. My IT specialists have not resolved the issue.Without getting too technical has anyone got advice for me?I am running W10. My first thoughts would be along the line of IP ranges.A few questions...
Did the old router provide DHCP for the network?If so, what range?
Does the new router provide DHCP for the network?If so, what range?
Are these ranges different?
Do you have any statically assigned/fixed IP addresses?
Can you get a screenshot/C&P of 'ipconfig /all' from a command prompt on a device that works and a device that doesn't? I can look at that. The old router was a BT HH5 which had little or no modification and it is a simple office situation with laptop printer hard drive and franking machine. I don’t think anything has a static ip. Even at the initial set up logging in to the new router was so slow it was virtually unresponsive. Everything works as long as the laptop is on Wi-fi only. I can also make it work by disabling Wi-fi on router and rebooting laptop and router. Connecting laptop by Ethernet cable obviously. The peripherals are wired although I can’t be sure they are using wired. They could have accessed the Wi-fi. I think you need to give a bit more information about your setup. You mentioned a "new" connection, do you now have two routers running in the premises (an old one and the new one) ?
It would also help to say exactly what "things wouldn't work correctly" and what the symptoms are. Have you got the latest firmware update, if so do a factory re-set and run the set-up again.
If you are using DHCP make sure every piece of equipment is set to use DHCP, if a particular item of equipment requires a fixed IP, make sure you reserve this IP in the router. Old router is on the shelf (disconnected).
Web browsers will not connect to internet or indeed log in torouter. One Cloud will not connect. Microsoft Exchange will not connect. The router is successfully on line to www.
To be honest if I can’t get on line I don’t get further to see what else works or doesn’t. It all fixes when I disconnect Ethernet from laptop and wireless only. I was thinking of doing that. The problem started at initial set up. I can’t remember what order I did things other than power off laptop, power up new router. Power up lap top. I possibly connected by Wi-fi and then plugged in Ethernet cable and the router log in took ages. If things take too long I start fiddling. For example disabling Wi-fi. Unplugging Ethernet. It took a couple of days to twig it was the two connections at one time that caused the issue.I am 90% certain the two connection methods conflict. I have no recollection of setting anything up with a static ip. At the next opportunity I will power down all peripherals and see if issue persists. Have you by any chance "bridged" the two NIC's together on your laptop...? If so that could create a loop in your network which would be bad. (If so, unbridge them.)
What happens if you disconnect your laptop and power it off and try using any other devices (phones, tablets, TV's, other computers, etc.) Are they OK or do they have problems also...?
Even if accessing the routers UI is slow, how is performance out to sites on the WWW...? Sorry being thick, NICs?Laptop will not get out to www at all when dual connected.Even when laptop is struggling the phone will connect to www by Wi-fi and even log in to router in an instant.
