I'm trying to replace CSP supplied router with an Archer C8. The CSP's DHCP server won't supply an IP address to the C8 unless I configure the hostname of the CSP's router in the WAN settings. The problem I'm facing is that the hostname uses non standard characters, a slash '/' and a @ symbol. The C8 WAN configuration webpage rejects this as an invalid character. Is there any way to get the C8 to accept the hostname with this format?

Thanks.
